Our verdict on each
O2 CZ Datamanie
O2 CZ Datamanie suits Czech readers who want a prepaid sim only line with eSIM, 5G and no credit check, and who will stay on their home network rather than travel. Entry sits at CZK 199 and the unlimited plan at CZK 499, a solid pair for a single market.
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
O2 CZ Datamanie
Pros
- Entry pricing starts at CZK 199 on prepaid billing.
- An eSIM, 5G and sim only are all available, so a handset you already own keeps working.
- No credit check is needed to start the line.
Cons
- Roaming in Europe runs on fair use terms rather than being included, so frequent travel abroad costs extra.
- Plan terms are 1 month, so plans renew on a short cycle with no longer term to hold a lower price.
- Service is confined to CZ, so the line does not travel beyond the Czech Republic.
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
O2 CZ Datamanie
Who it suits
- Readers in the Czech Republic who already have a phone and only need a line for calls and data.
- People who want to activate a prepaid line without a credit check or a long commitment.
- Travellers in Europe whose roaming is occasional rather than everyday.
Who should look elsewhere
- getesa, if you want a contract tariff alongside prepaid, since its billing options are prepaid and contract.
- yesss!, if you want rolling billing, since its billing options are contract, rolling and prepaid while this line is prepaid only.
- lonestar-cell-mtn, if you need a plan that serves a wider set of countries, since this line runs on CZ 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
O2 CZ Datamanie
How much does O2 CZ Datamanie cost to start?+
Plans start at CZK 199 on prepaid billing, with plan terms of 1 month. Because billing is prepaid, you pay for the period you want and nothing beyond it, so no minimum spend has to be reached before the line is live.
What does the unlimited data plan cost?+
The Datamanie NEO plan gives unlimited data for CZK 499 and renews on a short cycle. If your data use swings from month to month, that flat cost removes the guessing, while the capped plan at CZK 199 suits steadier, lighter use.
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.
