Our verdict

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.

Pros and cons

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.
  • It is a network selling in Cambodia, so the same firm runs the network behind the plan and takes your payment.

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.
  • Plans are sold in KH only, which narrows the choice if you split time between markets.

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.

Core features

You can take a SIM without a handset, which helps if your phone already came with one or you are switching numbers away from home. The network runs 5G, so a compatible phone can use the faster service rather than staying on an older connection. An eSIM is available too, so you can set up a line without waiting for a physical card to arrive. Data rollover is on, meaning data you leave unused in a period carries into the next one instead of disappearing, which matters on a trip where some days go unused. Roaming reaches 20 countries destinations, so short trips abroad are covered by an add-on rather than a new local plan.

The company behind it

Plans come from CamGSM Plc., a company headquartered in Cambodia. It has been trading since 1996, so the network and the name on your bill belong to the same established business rather than a new entrant. Support runs on chat and help centre, which means you can open a live chat or search the help centre. Both channels suit a prepaid arrangement with short plan contracts, where the questions tend to be about topping up, bundles and activating a SIM rather than about long-term account changes.

Frequently asked questions

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.

Can I get Cellcard without a new handset?+

Sim only is available, so the plan works with a handset you already own. An eSIM is offered too, which removes the wait for a physical card to arrive, and 5G runs on the network for a compatible phone. Roaming is a separate add-on for trips abroad.

Does unused data carry over?+

Data rollover is on, so whatever you leave in a period moves into the next one rather than expiring. On a prepaid bundle you top up only when you run low, rollover means an unused chunk is not wasted. It also makes heavier months cheaper to cover, since you are not paying twice for the same data.

What happens if I use my SIM abroad?+

Roaming reaches 20 countries destinations and is sold as a paid add-on rather than folded into the bundle. Your normal allowance applies at home in Cambodia, and you pick a roaming pack for the trip instead of a new local plan. Worth budgeting before you fly, since the add-on sits outside the price you pay each month.

How do I get help if something goes wrong?+

Support runs on chat and help centre only, so a live chat or the help centre is the route in rather than a call. For a prepaid plan with 1-month contracts, the usual questions are about top ups, bundles and SIM activation, all of which sit with the operator. Chat suits quick fixes during a trip.

Who is behind Cellcard?+

Plans come from CamGSM Plc., a company based in Cambodia that has been trading since 1996. Being an established operator matters for prepaid plans, where you pay up front and rely on the network being there next month. A long trading record says nothing about service quality, but it does mean the company is not new to the market.

Is Cellcard a network or a reseller?+

Cellcard is a network, so the firm selling the plan also runs the network behind it. When something is not working, the same organisation deals with the SIM, the coverage and the bill rather than passing you along. The AO MOBILE range is sold by the operator itself.
