High-data SIM guide

Best 200GB SIM Only Deals in the UK

Quick answer: For exactly 200GB of UK mobile data, start with the confirmed options from 1pMobile, iD Mobile, SMARTY and giffgaff. The network is the main difference: 1pMobile uses EE, iD Mobile and SMARTY use Three-based coverage, and giffgaff uses O2. iD and SMARTY can be cheaper, while 1pMobile suits you if EE signal and a rolling 30-day Boost matter more than the lowest bill. Check 1pMobile's 200GB deal or compare all 100GB+ SIM deals to see current prices and neighbouring allowances.

200GB makes sense if you regularly pass 100GB or 150GB, though a smaller plan may do the job for less. A well-priced unlimited or 250GB plan can be the better buy if you go over. Match the network, total cost and commitment to the data you actually use.

Which UK operators offer a 200GB SIM-only plan?

Four operators had an exact 200GB offer in DealPriceCheck's selected catalogue when the offers were checked: 1pMobile, iD Mobile, SMARTY and giffgaff. These linked product cards are the buying shortlist, not a claim that no other UK provider sells 200GB. A 200GB rolling plan, a prepaid plan and a longer contract can have very different costs and cancellation rules, even when the data allowance matches.

Compare today's exact deals: Open the four linked 200GB cards and note the current payment, commitment and renewal method on each. Compare 1pMobile's 30-day Boost with the one-month iD product, SMARTY's prepaid plan and giffgaff's monthly rolling product. Do not substitute a promotional 12- or 18-month price for a rolling plan. Check the next higher allowance and Unlimited on the same network too: a retailer-exclusive unlimited offer may occasionally be priced as keenly as a network's own 200GB product, but availability and eligibility differ by sales channel.

Ready to buy on EE? The exact 1pMobile 200GB offer has its own View Deal button through our existing Awin route. Read Full plan details, including excess-data charging, before checkout. If EE is not suitable or 1pMobile costs more for your needs, compare the other 100GB+ live offers. Never choose weak coverage simply to match a 200GB search term.

Do Lyca, Lebara and Sky Mobile have a 200GB plan?

No exact 200GB partner offer from Lyca, Lebara or Sky Mobile was established in our selected cards for this comparison. These three are DealPriceCheck affiliate partners, but their other allowances, including possible unlimited options, must not be presented as labelled 200GB deals. This distinction matters because a broader data plan can still win on price, network or flexibility without meeting the exact keyword.

If EE coverage is your reason for looking at 1pMobile, compare the real allowance and term with Lyca Mobile's selected offers. For Vodafone coverage, see Lebara's data plans. For O2 coverage and an unlimited alternative, check Sky Mobile alongside giffgaff. A partner offer doesn't automatically beat a non-partner one.

Which 200GB SIM is best for you?

No universal winner exists. Start with a network that works at your home, workplace or hotspot location, then decide whether the lower cost of iD or SMARTY outweighs the flexibility and coverage of the other options. A low headline price on an unreliable network is not a saving.

Is 1pMobile 200GB worth paying more for EE coverage?

1pMobile's 200GB Boost gives a fixed UK allowance over 30 days, with standard UK calls and texts, on EE's network. That makes it a real alternative to Three-based 200GB deals where EE gives stronger indoor or commuting coverage.

Its case isn't that it is the cheapest 200GB operator. It combines EE coverage, a finite high-data allowance, eligible 5G and a short rolling commitment. If Three reception is poor at your address and EE is dependable, paying more for data that works is reasonable. If EE, Three and O2 all work equally well, cheaper alternatives deserve a look.

Before checkout: the specific 200GB Boost renews automatically every 30 days under the published terms. Crucially, 1pMobile separately charges 1p per MB for excess data taken from your account credit, and its product information describes automatic £10 credit top-ups when the usage balance falls below £2. So 200GB is not a harmless soft limit. At the published rate, one extra GB could cost roughly £10 when charged per MB, depending on the operator's billing units. This is an illustration of a real out-of-bundle rate, not an extra fee on every 200GB plan. If your hotspot or downloads regularly reach the allowance, check your account's top-up and spending controls and consider an additional Boost or a larger 1pMobile plan before drifting into out-of-bundle use. Its EU roaming data cap is separate from the UK 200GB allowance.

Purchase route: open the exact 1pMobile 200GB deal, check Full plan details and then use its existing affiliate View Deal button. This is the relevant product-specific route, not a generic 1pMobile international-calling page.

iD Mobile 200GB: a price benchmark with application requirements

iD gives a strong price benchmark for 200GB on Three-based coverage. Its range has included 200GB pay-monthly SIMs on rolling and longer terms, plus neighbouring 250GB, 300GB and unlimited offers, and a larger allowance sometimes beats the exact 200GB option on value.

The linked iD offer is a one-month pay-monthly contract, not a prepaid SIM. iD explicitly says its pay-monthly SIM-only applications require a credit check, even when the advertised minimum term is short. That is a real distinction from prepaid SMARTY or 1pMobile Boosts. iD's wider range also contains longer commitments, so compare the exact linked plan rather than borrowing a promotion from a different contract.

On eligible iD plans, rollover carries unused data into the following month only. It doesn't build a permanent bank, so it helps if you use 100GB one month and more the next but isn't a reason to overbuy 200GB every period. Roaming has its own fair-use ceiling.

See iD Mobile's 200GB listing and its wider range. iD isn't a DealPriceCheck affiliate, so this is a fair comparison with no commission behind it.

SMARTY 200GB: a simple prepaid rolling option

SMARTY is worth comparing if Three-based coverage works at home, on your journey and wherever you use most of your data. Its 200GB SIM is prepaid on rolling monthly terms, with no conventional credit check advertised on its ordinary plans, eSIM on compatible devices and tethering allowed against the UK allowance.

That suits renters, students and people testing mobile internet before committing to a long contract. SMARTY explicitly permits tethering with the full UK allowance, including using a phone as a hotspot. If you only use around 100GB, a smaller plan can cost less; if you routinely exceed 200GB, compare its unlimited option. Abroad is different: SMARTY's standard included EU roaming fair use is 12GB per plan month on large plans, with a paid EU Roaming Pass available to access more of an unused UK allowance for a limited time. Do not assume free roaming of the whole 200GB.

Review SMARTY's 200GB listing and the full SMARTY selection. SMARTY isn't an approved affiliate, so its purchase link goes direct to the operator.

giffgaff 200GB: an O2 option, so compare its unlimited price

giffgaff gives you an O2-hosted alternative, which matters if O2 works in your home or workplace and EE and Three don't. It sells different plan types, so check the product's actual rolling or fixed term, eSIM eligibility and roaming limit, because conditions aren't identical across plans.

One particularly easy pricing mistake: giffgaff offers 200GB under different purchase models, including a monthly rolling plan, an 18-month contract and pay-as-you-go-style options. The allowances may match while the monthly price and flexibility do not. Our linked 200GB card is the rolling choice; do not use a cheaper fixed-term headline as if it came without that commitment. Check the contract length shown for the exact linked product and verify it at checkout; do not let a general price-rise note about another plan type change which product you think you are buying. A longer contract may still suit you, but calculate its full cost. Also compare O2-based unlimited: at some prices it can be a better option for frequent hotspot users than buying extra data on the rolling 200GB plan.

Is 200GB enough for everyday mobile internet?

For one person, 200GB is a large allowance. It covers frequent video calls, social media, commuting entertainment and substantial hotspot use at moderate quality. It isn't infinite, and a TV, laptop, console or several people can use it up quickly if the phone replaces home broadband.

Spread evenly over 30 days, 200GB averages about 6.7GB per day. That is a planning figure, not an actual daily cap. For example, large updates and downloaded films may use much of an allowance in a weekend even if weekday usage is small. Check whether your operator issues usage alerts and what happens at zero remaining GB, particularly if automatic charging or top-ups are possible.

Your usageDoes 200GB make sense?What to examine

How long does 200GB last for Netflix?

Netflix's own guidance gives upper planning figures of about 1GB an hour at High SD, 3GB at HD and 7GB at Ultra HD. These are "up to" values, and your phone's playback setting may use far less. See Netflix's data-usage guidance.

Netflix settingPublished use (up to)200GB on video aloneWith 40GB kept for everything else
High SD1GB per hour200 hours160 hours
High HD3GB per hourAbout 67 hoursAbout 53 hours
High 4K7GB per hourAbout 29 hoursAbout 23 hours

Two hours of HD a day for 30 days is 60 hours, which at Netflix's published HD upper figure could use up to 180GB, leaving very little for other mobile activity. By contrast, Netflix's mobile Save Data setting aims for roughly six viewing hours per GB, so your actual phone use may be far lower. Quality, playback settings and device matter; the table is a planning ceiling, not a prediction for YouTube, TikTok, gaming or every Netflix stream.

Is 200GB enough to use a phone as a hotspot?

For a single laptop or a temporary connection, it can be. Check what runs in the background, because cloud backups, software updates, game downloads and other devices can use tens of gigabytes without looking like browsing, and a TV may request higher quality than a phone would.

A 65GB game download followed by five hours of Ultra HD streaming at up to 7GB an hour could use about 100GB in just two activities. Repeat that twice and a 200GB period is exhausted before routine browsing or updates. If the phone is the household's main connection, assess sustained evening speeds, latency, router compatibility and fixed-broadband alternatives; a large phone allowance alone does not make home broadband reliable.

Our hotspot and tethering guide covers hardware and restrictions. SMARTY explicitly permits tethering against its UK allowance, and for any other product you should verify the device and plan terms. A phone SIM isn't automatically a substitute for home broadband or a data-only router plan.

Should you buy 150GB, 200GB, 250GB or unlimited?

Start from your highest normal usage period and ignore the advertised GB. If your busiest normal month was 115GB, 200GB may add nothing over a suitable 150GB plan. If you regularly hit 190GB, 200GB leaves no buffer for a trip or a big download. If a 250GB or unlimited plan costs less than 200GB on an equally reliable network, don't let the "200GB" label stop you moving up. A price from one provider's own shop and a price on a third-party sales channel may differ, so compare the actual plan terms and checkout price, not merely the headline GB. Our 100GB vs unlimited guide covers that wider decision.

Your recorded use per periodCompare firstWhy
Usually below 90GB100GB or smaller200GB could be needlessly expensive
Often 100 to 130GB150GB, then 200GBHeadroom without automatically paying for unlimited

Swings from 50GB to 200GBA flexible plan with rollover or plan changesContract flexibility may matter more than average GB

These ranges are editorial planning guides, not official thresholds or typical British usage. Look at three or more complete bills if you can, and note whether each covers 30 days or a calendar month. The mobile data usage guide shows how to find your figure.

Worked example: is 150GB to 200GB worth the jump?

Take two hypothetical rolling 30-day SIMs on equally reliable networks:

150GB SIM200GB SIM
Renewal price£15£18
12 renewals£180£216
Differencen/a£36 extra
If normal use is 115GBPlenty of spare data85GB spare that may go unused
If normal use is 165GBShort without a plan change or add-on35GB spare

At 115GB of normal usage, the hypothetical 150GB choice saves £36 across 12 renewals, assuming the two offers work equally well. But a hypothetical £5 top-up in eight periods costs £40, wiping out that saving. Do not assume these invented £5 add-ons exist with either real provider, and do not treat 1pMobile's published out-of-bundle 1p/MB rate as this £5 example. Use the actual charge or Boost price displayed at checkout.

Calculate the price difference across the whole period, then compare it with the extra data you will realistically need. A low price per gigabyte on 50GB more is no reason to buy it.

Worked example: 200GB versus unlimited over a year

Assume a 200GB rolling SIM costs a hypothetical £18 every 30 days and a comparable unlimited SIM costs £21. The £3 gap is £36 over 12 renewals (360 days), which is not twelve calendar months.

If your busiest normal use stays below 160GB, unlimited may be unnecessary provided the capped plan is genuinely cheaper. But seven hypothetical £6 top-ups would cost £42, more than the £36 premium for unlimited in this example. Real overage mechanisms differ: some providers require purchasing extra data, others charge account credit, and the plan may stop data until you act. Compare the actual mechanism, then inspect speed, fair use, hotspot and roaming restrictions using our unlimited fair-use explainer.

Compare real offers: 200GB and neighbouring allowances in the 100GB+ catalogue against selected unlimited SIMs. Open Full plan details before View Deal to check the real renewal price and any contract liability.

Which 200GB SIM has the best coverage and 5G speed?

No nationwide winner exists for every home, postcode and commute, and a 200GB allowance doesn't guarantee a speed. For the plans in this guide:

Use Ofcom's Map Your Mobile for indoor and outdoor predictions for EE, Three and O2. Its performance view also summarises the likelihood of successful video streaming by postal district. It is a guide, not a promise of speed in a particular bedroom or train carriage.

For heavy data, test where you will actually use the 200GB: the desk where you tether, the room where you stream in the evening and the route you travel. A 5G logo matters less than a stable connection at peak time.

Does a 200GB SIM need 5G?

No. 200GB is the quantity of data you can use and says nothing about the connection speed you need. A stable 4G network handles HD video and video calls. 5G can speed up downloads or help in busy areas, but it doesn't make 200GB last longer, and a faster connection can use your allowance sooner if apps pick higher-quality streams or you download more large files.

Check any speed tier, tethering policy and your phone's band support. Our 5G vs 4G guide and speed-caps guide cover those in depth.

Is a rolling 200GB SIM better than a 12 or 24-month contract?

A rolling 30-day plan suits you if your budget, network or home may change. A 12 or 24-month contract is worth it if it gives a real total-cost advantage and you are sure about coverage. Neither term is automatically cheaper.

Watch three different clocks:

  1. 30-day allowances renew every 30 days, so twelve renewals cover 360 days, not 365.
  2. Calendar-month billing has different renewal dates and may have different notice requirements.
  3. Minimum-term contracts can keep you liable for payments or early-termination fees even if you stop using the SIM.

A low opening payment can rise after an introductory period; add all scheduled charges, potential early-exit liabilities and any upfront fee. giffgaff's rolling, longer contract and PAYG-labelled 200GB options must be treated as separate products, not merged into one imagined price. iD's one-month plan likewise cannot borrow the promotional price of a 12-month offer. Where a future price change is merely permitted rather than quantified, identify the uncertainty instead of manufacturing a guaranteed total.

If credit history matters: SMARTY's ordinary prepaid plans need no conventional credit check, and iD's pay-monthly SIM-only application does. For a no-credit-check route, see our no-credit-check SIM guide and confirm the product's payment and identity requirements.

Can you use 200GB abroad?

Mostly no. The 200GB figure is a UK data amount, and roaming follows separate rules, destinations and fair-use limits. Even a plan with inclusive EU roaming may cap the data you can use abroad at a much smaller amount, which matters if you expect to run a 200GB hotspot on holiday.

For a concrete distinction, 1pMobile's 200GB Boost currently has a 14GB EU roaming cap under its published Boost terms; SMARTY's normal included EU fair-use data cap is 12GB on its large plans, although its optional paid EU passes can change the limit temporarily. iD and giffgaff have their own different rules. The limits, eligible destinations and pass availability are operator terms, not guarantees for every future product. Verify your actual holiday country and whether your roaming usage will trigger charges or need an add-on.

If roaming is central to your choice, use our EU roaming comparison and don't assume 200GB follows you overseas.

Should you get an eSIM or a physical SIM for 200GB?

It makes no difference to the allowance: eSIM doesn't make 200GB faster or bigger. Eligible operators offer eSIM on compatible devices, but support varies by phone model, account type, location and activation method.

Check your exact handset and plan if you need eSIM immediately, especially with an imported or eSIM-only phone. If indoor signal is patchy, check Wi-Fi Calling and 4G Calling compatibility too, because a shared EE, Three or O2 host network doesn't mean every brand supports the same features.

Our UK eSIM catalogue helps if digital activation is a requirement. The provider pages for 1pMobile, iD, SMARTY and giffgaff let you compare terms before ordering.

How do you buy the right 200GB SIM?

  1. Check your usage. Read your last three complete allowance periods and ask whether you need 200GB or 150GB would do.
  2. Choose networks that work. Check Ofcom for your postcode, then test indoor performance if you can.
  3. Compare exact 200GB options: 1pMobile, iD, SMARTY and giffgaff. The same GB label doesn't make them interchangeable.
  4. Compare one tier down and up. Check 150GB, 250GB or 300GB and unlimited in the 100GB+ catalogue, so an exact-200GB search doesn't lock you into a worse deal.
  5. Read the full payment schedule. Check the term, introductory discounts, price changes, data extras and the cost of leaving.
  6. Check hardware and roaming. Confirm tethering, eSIM or physical SIM support, speed-related terms and the data you can use abroad.
  7. Buy through the matching offer card. Open Full plan details, verify the 200GB product, term and out-of-bundle charges, then use View Deal. The 1pMobile 200GB card has the existing product-specific Awin route; there is no reason to replace it with an untracked merchant URL.

Frequently asked questions

What is the best 200GB SIM-only deal in the UK?

No single deal wins for everyone. Compare the exact 200GB offers from 1pMobile (EE), iD Mobile (Three), SMARTY (Three) and giffgaff (O2). A cheaper Three-based plan may be best where its signal is good, and 1pMobile is worth considering for EE coverage and a rolling 30-day Boost. Check the current total cost and term, not an outdated price list.

Which 200GB SIM is cheapest?

That changes with promotions, term and sales channel. iD and SMARTY have shown cheaper exact-200GB offers than 1pMobile in DealPriceCheck's selection, but it is not a permanent ranking. Compare like with like: a one-month iD payment is not an 18-month giffgaff total, and a prepaid Boost is not a financed phone. Use the live high-data cards and check the entire payment schedule.

Is 200GB a lot of mobile data?

Yes, for a typical phone user it is a large fixed allowance, though repeated high-quality streaming, several hotspot users or big downloads can use it up. Across 30 days it averages about 6.7GB a day, and your real needs matter more than an average.

Is 200GB enough for Netflix and YouTube?

Often, depending on quality and hours. At Netflix's published upper HD use of 3GB an hour, 200GB covers about 67 hours with no other mobile data use. YouTube and TikTok have no single hourly rate, so leave room for messaging, background activity and downloads.

Is 200GB enough for a hotspot or home internet?

For occasional tethering or a temporary single-user connection, yes. A household watching 4K TV, downloading games and using several laptops can burn through 200GB fast. Check tethering permission, and consider unlimited or fixed broadband if the hotspot is your main home connection.

Is a 200GB SIM better than unlimited data?

Choose 200GB if it comfortably covers your busiest normal period and costs meaningfully less on a suitable network. Choose unlimited or a bigger fixed tier if you regularly exceed 200GB, pay for top-ups or have unpredictable usage. Unlimited may still carry fair-use, speed or roaming conditions.

Can you get 200GB on a 30-day rolling SIM?

Yes. The offers we checked include a 1pMobile 200GB Boost, a SMARTY prepaid 200GB plan and rolling 200GB products from other operators. Confirm whether the product runs for 30 days or bills by calendar month, and whether it is prepaid or pay-monthly with a credit application.

Does a 200GB SIM have a speed cap?

The allowance says nothing about speed. Check the plan's speed-tier terms, network, local congestion, device support and fair-use policy. Some 5G plans are not speed-restricted in ordinary UK use and others have limits, and a 4G connection with good coverage can outperform a poor 5G signal.

Can I use all 200GB in Europe?

Not under the standard included allowances of the providers checked here. For example, 1pMobile publishes a 14GB EU limit for its large Boosts, and SMARTY's normal included EU allowance is capped at 12GB, with paid passes as an alternative. Other operators differ. Check your destination and actual roaming terms before travelling.

Does iD Mobile need a credit check for its 200GB SIM?

Yes for the pay-monthly SIM-only offer linked here: iD says its applications require a credit check, including short-term pay-monthly SIMs. A rolling payment is not automatically prepaid. SMARTY and the relevant 1pMobile Boost advertise no conventional credit check, but still have payment, account and verification requirements.

Can I keep my number when I switch to a 200GB plan?

Usually, for a UK mobile number. Text PAC to 65075 and give the code to the new provider. Porting doesn't clear any minimum-term or handset-finance liability.

Verdict: which 200GB SIM should you buy?

For exactly 200GB on EE, first inspect the 1pMobile 200GB product and use its verified View Deal button if the terms suit you. Remember that automatic renewal and out-of-bundle charges matter if you tether heavily. On working Three-based coverage, compare iD Mobile for price and SMARTY for prepaid flexibility. On O2, check giffgaff but identify whether the offered 200GB price belongs to the rolling or longer-term product.

Then make one last comparison with 150GB, 250GB and other high-data offers and unlimited SIMs. The best deal is the lowest sensible total cost for enough usable data on a network that works, not necessarily the plan with 200GB in its name.
