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.
Youfone
Pros
- Magic Deal plans start at €1 a month, well under the site wide entry price median of €9.30.
- A credit check is not required, while 58.7% of the listings on the site do run one.
- Roaming in the EU is included, while the wider market sits mostly on fair use (32.5%) or paid (31.4%) terms.
Cons
- The Magic Deal bundles behind the €1 headline price are sold on the longest of its 1, 12 and 24 month terms, so the cheapest price carries the longest commitment.
- Billing covers contract and rolling only, so there is no prepaid top up option in the range.
- On entry price Youfone ranks 19 of 258 brands, so cheaper entry points exist further down the list.
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.
Youfone
Who it suits
- Readers in the Netherlands who want a sim only line with a large data bundle at €1 a month.
- Readers with a thin credit file or no credit history, since a credit check is not required.
- Travellers who cross EU borders, since roaming is included.
Who should look elsewhere
- Prepaid shoppers who top up as they go, since Youfone's billing covers contract and rolling and the priced bundles are all fixed term.
- Buyers who would rather buy from the operator itself, since GETESA is a network with its own infrastructure.
- Readers outside the Netherlands, since the service runs on KPN while Lonestar Cell MTN is a network for a different market.

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.
Youfone
How much does a Youfone sim only plan cost at the start?+
Prices start at €1 a month on the Magic Deal plans, which pair a large data bundle with a multi year term. That sits below the site wide entry price median of €9.30, and Youfone ranks 19 of 258 brands on entry price, so it is cheap without sitting at the top of the cheap list.
How long is the contract and can I leave early?+
Youfone sells over contract terms of 1, 12 and 24 months, and billing runs on contract and rolling terms. The Magic Deal bundles that carry the lowest monthly cost are each priced for a multi year term, so the cheapest headline price is tied to a longer commitment rather than a rolling one.
