Our verdict on each
Chattr SIM Only
Chattr SIM Only suits people in GB who want a rolling SIM that can leave any month and will not raise the bill. Roaming is already included.
TalkMobile
TalkMobile suits adults in GB who want a plain sim only deal on Vodafone and Three with no credit check. Entry sits at £4.98, but that rate covers only the opening part of the annual term, so the standard rate afterwards is the figure to plan around.

Pros and cons
Chattr SIM Only
Pros
- £5 is the entry price on the SIM only plan, and No price hikes means the renewal bill does not climb
- included roaming across 43 countries comes as standard rather than as an add-on
- Rolling billing on a term of 1-month means the line can end without an exit charge
Cons
- Support runs on email only, so a question with no quick email answer waits for a reply
- Service covers GB alone, so the SIM does not work for a trip outside the UK unless roaming applies
- Chattr SIM Only is an mvno on the O2 network, so coverage follows the host rather than a network of its own
TalkMobile
Pros
- No credit check is required, so a past credit issue does not block an order.
- eSIM, 5G, wifi calling and hotspot sharing are all included as standard, with nothing extra to switch on.
- Host network is Vodafone and Three, so a line can sit on either network without changing provider.
Cons
- The £4.98 rate is introductory, applying to the opening part of the annual plan only, after which the standard rate takes over.
- Roaming is fair use across 47 countries rather than an unrestricted allowance, so heavy roaming abroad is capped by the terms.
Who each suits
Chattr SIM Only
Who it suits
- Anyone in GB already holding a handset and happy to bring their own SIM
- Travellers who want included across 43 countries without a roaming add-on
- People who need a credit check free line and prefer rolling billing over a locked contract
Who should look elsewhere
- GETESA, Lonestar Cell MTN and yesss! sell as networks rather than an mvno, so buyers wanting the host's own support and shop presence should look there first
- Phone buyers wanting a handset bundled with the line, as this offer is SIM only
- People wanting phone or chat support, since help runs on email alone
TalkMobile
Who it suits
- Adults in GB who want a sim only line on Vodafone and Three without a credit check.
- People with an eSIM handset who want 5G, wifi calling and hotspot sharing active from the start.
- Travellers who need fair use roaming across 47 countries rather than a fully unrestricted allowance.
Who should look elsewhere
- Buyers who want the host network's own tariff: GETESA and yesss! both sell as network operators, while TalkMobile is mvno.
- Anyone set on unlimited data, since no unlimited plan appears among the reference plan prices; yesss! and Lonestar Cell MTN run as network operators on their own brands.

Questions about each
Chattr SIM Only
What does the cheapest Chattr SIM Only plan cost?+
The SIM only line starts at £5. That is the entry price for the plan rather than a promotional first bill, and No price hikes applies, so the same figure carries over to renewal. Larger data allowances are available on the same rolling billing.
Does the price go up when I renew?+
No. The stated position is No price hikes, so the monthly figure a customer starts on is the figure carried forward. Renewal pricing is therefore predictable, which is unusual among rolling SIM only deals where providers often adjust charges over time.
TalkMobile
How much does a TalkMobile sim only plan cost at the start?+
Entry pricing starts at £4.98. That figure is introductory on the annual plan and covers only the opening part of the term, with the standard monthly rate applying after that. A monthly plan with a smaller allowance is listed as well, so the annual rate is the figure that matters at renewal.
Do I need a credit check to get a TalkMobile SIM?+
No credit check is required, and that is why the provider shows up in no credit check plan lists. Entry at £4.98 can be set up without a credit search on record, so a past credit issue does not stand in the way of ordering.
