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.
Simpel
Simpel is a Dutch virtual network operator for people who want a cheap sim only plan, a 5G connection and an eSIM without a credit check, with tariffs starting at €2.50 a month. The catch is commitment: plans run on 12 and 24, and data rollover is not on the menu.

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.
Simpel
Pros
- A credit check is not required, so an application does not rest on a credit file.
- An eSIM and 5G are both offered, so a recent handset works without waiting for a card in the post.
- EU roaming is included in the sim only line, and only 36.1% of the listings include it.
Cons
- Data rollover is not offered, so unused data from a quiet month is lost rather than carried into the next one.
- Plans run 12 and 24 with billing on contract, and leaving early is governed by After minimum term rolling monthly with 1 month notice, while only 78% of the listings are month to month.
- Support runs on email, help centre and community, with no phone line listed, while 81.5% of the brands offer one.
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.
Simpel
Who it suits
- People in NL who bring their own handset and want sim only service on 5G with no credit check.
- Households that want both lines in one place, since fibre runs to 1,000 Mbps and hardware is Modem included.
- Travellers who would rather not buy a roaming pack, since EU roaming is included.
Who should look elsewhere
- People set on a network operator rather than a virtual one: Simpel is an mvno, while GETESA (network) and yesss! (network) sit on the other side of the market.
- Anyone unwilling to sit a full term: plans run 12 and 24 with notice set by After minimum term rolling monthly with 1 month notice, so if your plans may change, read the terms at Lonestar Cell MTN (network) as well.

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.
Simpel
How much does a Simpel sim only plan cost to start?+
Sim only plans start at €2.50 a month, below the €9.30 median across the brands tracked here. The lowest priced bundle with a larger data allowance runs on a year contract, and unlimited calls come as a small monthly add-on rather than a plan of their own. Read the tariff terms, since the entry price is separate from what you pay later.
How long is the contract and can I leave early?+
Plans run 12 and 24 with billing on contract, and the notice terms are After minimum term rolling monthly with 1 month notice. Only 78% of the listings are month to month, so a shorter rhythm does exist elsewhere in the market. Read that notice wording before you sign, because rolling monthly is not the same as having no term.
