Our verdict on each
cellcard
Cellcard is a Cambodian network that suits visitors and prepaid users who want data at a low entry price rather than a long fixed term. The AO MOBILE range starts at $1, sold on prepaid and contract terms with an eSIM option and rollover on the bundles, so a short stay costs little.
congstar
congstar suits anyone in DE who wants a low entry price, short terms and no renewal jump, on the Telekom network. Entry starts at €2, and the price rise rule keeps that figure as agreed, though the top data tier stops short of unlimited.

Pros and cons
cellcard
Pros
- AO MOBILE plans start at $1, and each prepaid bundle rolls leftover data into the next period.
- Plan contracts run 1 month and billing is prepaid and contract, so a trip does not need a long fixed term.
- An eSIM gets you a line without a store visit, and roaming reaches 20 countries destinations.
Cons
- Roaming is a paid add-on rather than part of the bundle, so the 20 countries destinations cost extra on top of the plan.
- Support runs on chat and help centre only, so a line fault means a chat or a store rather than a call.
- Billing is prepaid and contract, so there is no rolling monthly option of the kind yesss! lists in contract, rolling and prepaid.
congstar
Pros
- Entry pricing starts at €2, well under the €9.30 site median, with prepaid billing available through contract, rolling and prepaid.
- No price rise - price stays as agreed, so what you sign up for is what you keep paying at renewal.
- Terms run 1 month, short enough to leave without a long tie-in.
Cons
- The largest reference plan, Allnet Flat L, is a capped data allowance, so constant streaming or heavy hotspot sharing meets a ceiling.
- The entry figure of €2 belongs to a prepaid bundle, so the monthly contract option Allnet Flat S sits well above the €9.30 site median.
- Support reaches chat, phone and help centre, where email is not among the listed channels.
Who each suits
cellcard
Who it suits
- Travellers who want data working before they land, since an eSIM is available and a SIM can be taken without a new handset.
- Prepaid users who top up only when they run low, since rollover carries unused data forward and plan contracts run 1 month.
- People who want 5G on a plan that does not tie them in, since the same bundles cover speed and leftover data.
Who should look elsewhere
- Travellers who expect roaming inside the bundle, since cellcard sells roaming as a paid add-on on top of the plan.
- Buyers after a rolling bill, since yesss! lists contract, rolling and prepaid terms and cellcard bills on prepaid and contract.
congstar
Who it suits
- Households wanting one bill option across contract, rolling and prepaid types, from prepaid to contract.
- Travellers in the EU who want roaming at included rather than paying per use.
- People on the Telekom network who would rather buy through an mvno than go direct.
Who should look elsewhere
- Anyone who needs truly unlimited data, since the congstar reference plans stop at Allnet Flat L; GETESA, listed as a network, is worth reading if you prefer a direct network tariff.
- Those wanting a single monthly contract price, since the cheapest figure belongs to a prepaid bundle while Allnet Flat S costs more each month.

Questions about each
cellcard
What does a Cellcard plan cost at the start?+
The AO MOBILE range starts at $1 for a prepaid bundle, with a 5G version of the same range sitting higher. Billing is on prepaid and contract terms, and plan contracts run 1 month. In practice you are buying a bundle and topping up again rather than signing a long fixed deal.
Do prices rise when I renew?+
Renewal is simply the next top up on prepaid and contract terms, with plan contracts of 1 month. The AO MOBILE bundles are listed as monthly prepaid plans, so the same bundle price applies each time you buy one. That is easier to budget than a subscription with a cheaper opening month that turns into a higher charge.
congstar
How much does congstar cost to get started?+
Entry starts at €2, which sits below the €9.30 site median for this kind of plan. That figure belongs to the prepaid option, Prepaid wie ich will, on a short prepaid billing cycle. The contract option, Allnet Flat S, costs more each month, so the cheapest headline price and the monthly contract are separate products.
Will my monthly price go up when I renew?+
The stated rule is No price rise - price stays as agreed. Nothing in that rule allows the agreed figure to climb, which is the main thing to check before signing a contract option. Contrast that with typical market behaviour, where the €43 site median for a post-contract price sits well above the €9.30 entry median.
