Next update: when Talkmobile or iD Mobile changes its high-data SIM-only prices.
By: Switch Editorial Team, Switch Squid Ltd
As of 6 October 2026, Talkmobile’s SIM-only page lists 100GB at £4.98 a month for the first 3 months (then £9.95 from 6 January 2027) and 150GB at £5.97 a month for the first 3 months (then £11.95), both on 12-month contracts, plus 30-day plans at lower data tiers. We couldn’t see a 200GB plan on that page when we checked. If you want around 200GB on a flexible month-to-month plan today, the closest like-for-like we can link to is iD Mobile 200GB at £12 a month on a 30-day rolling plan, with unlimited UK calls and texts and 5G where available. The main limitation: iD runs on Three’s network, not Vodafone’s, so check coverage where you live and work first.

This guide is for people searching for Talkmobile 200GB SIM only: what Talkmobile actually lists today, what a 200GB allowance suits, and how the nearest live 200GB option compares on total cost and network.
What Talkmobile lists today
Talkmobile is a Vodafone-network provider. Its SIM-only page on 6 October 2026 showed these headline plans:
| Talkmobile plan | Data | Price | Contract | 12-month total |
|---|---|---|---|---|
| 100GB half-price offer | 100GB | £4.98 a month for 3 months, then £9.95 | 12 months | £104.49 |
| 150GB half-price offer | 150GB | £5.97 a month for 3 months, then £11.95 | 12 months | £125.46 |
| 30-day plans | From 15GB | Shown on Talkmobile’s site | 30 days rolling | Depends on plan |
Talkmobile says all its SIM-only plans include unlimited minutes and texts, 5G where available, Wi-Fi calling, no credit check, and roaming in 47 European destinations with up to 5GB of data at no extra cost. Prices and plans can change, so check Talkmobile’s own site on the day you buy. Talkmobile isn’t on our comparison list, so we don’t link to it directly.
Who a 200GB plan suits
200GB is a heavy allowance. It tends to suit people who use their phone as a hotspot for a laptop most evenings, stream video daily on the commute, or don’t have reliable home broadband. If your last three bills each came in under about 80GB, a 100GB or 150GB plan will usually cost less over a year.
If you regularly go past about 180GB, an unlimited plan may be simpler, because you won’t need to keep an eye on your usage. Your phone’s settings (or your current network’s app) will show your monthly usage, which is the best guide to the right tier.
Cost comparison: 12 months at around 150–200GB
| Plan | Data | Monthly price | Contract | 12-month total | Network |
|---|---|---|---|---|---|
| iD Mobile 200GB | 200GB | £12 | 30-day rolling | £144 (if the price stays the same) | Three |
| Talkmobile 150GB offer | 150GB | £5.97 for 3 months, then £11.95 | 12 months | £125.46 | Vodafone |
| Talkmobile 100GB offer | 100GB | £4.98 for 3 months, then £9.95 | 12 months | £104.49 | Vodafone |
Prices checked on 6 October 2026. Talkmobile figures are from talkmobile.co.uk; the iD figure is from the iD Mobile plan we link to. Rolling plans can change price with notice, so the 12-month total for iD assumes today’s price holds.
iD Mobile 200GB — £12 a month (£144 over 12 months if the price holds)
- 50GB more than Talkmobile’s 150GB offer for about £18.54 more over a year
- No 12-month lock-in
Talkmobile 150GB vs iD 200GB: which fits you?
Choose Talkmobile’s 150GB offer if Vodafone gives you the best signal at home and work, 150GB covers your usage, and you’re happy to commit for 12 months. It is the lowest total cost of the three.
Choose iD Mobile 200GB if you need the extra data or want the freedom to leave at short notice, and Three’s coverage is good where you spend your time. A rolling plan is also a sensible way to test a network for a month before committing.
Coverage matters more than a pound or two a month. Use Ofcom’s mobile coverage checker for your home, workplace and commute before you switch.
Roaming, 5G and eSIM
Talkmobile includes roaming in 47 European destinations with up to 5GB of data. iD Mobile also includes EU roaming on many of its SIM-only plans; check the roaming terms on the plan page before a long trip, because fair-use limits differ. Both providers offer 5G where there is coverage and your phone supports it, and both support eSIM on compatible handsets, which avoids waiting for a SIM in the post.
How to switch and keep your number
- Text PAC to 65075 from your current phone. You’ll get your code by text, usually straight away.
- Order your new SIM or eSIM and enter the PAC code during checkout.
- Your number usually moves within one working day. Keep your old SIM in until it does.
If you are still in a minimum term with your current provider, early termination charges may apply. Check before you request the PAC.
Rolling vs 12-month contracts
A 30-day rolling plan gives you flexibility: you can change plan or leave with notice and no early exit fee. A 12-month contract often has a lower introductory price, like Talkmobile’s half-price first three months, but you are committed for the year. If you are unsure about coverage or how much data you use, rolling is the lower-risk choice.
Sharing data and second lines
A 200GB allowance is usually enough for one heavy user, including evening hotspot use. If two or more people share one phone’s hotspot every day, separate SIMs or an unlimited plan may work out better. Tablet and smartwatch add-ons are usually separate products, so check the provider’s terms before assuming data is shared.
