Our verdict

Taiwan Mobile suits anyone living in Taiwan who wants a network operator's own SIM only or 5G plan rather than an MVNO. Entry starts at TWD 100 on a prepaid card, the 5G plan with unlimited data costs TWD 1,399 a month, and contract terms run long.

Pros and cons

Pros

  • Entry is low in local terms: the prepaid card starts at TWD 100 and carries a small data bundle rather than a monthly bill.
  • The 5G plan pairs a monthly data bundle with bonus data and unlimited 5G data during the contract, priced at TWD 1,399.
  • Sim only, eSIM, WiFi calling and hotspot sharing are all available, so a phone already in hand can be brought across.
  • Billing covers both contract and prepaid terms (contract and prepaid), so a short stay and a settled stay can use the same seller.

Cons

  • Contract plans run 24 months, which suits a settled stay rather than a short trip.
  • EU roaming is paid rather than included (paid), so time in Europe adds a separate cost.
  • Support runs on phone and help centre only, with no chat or email listed for questions that are not urgent.
  • yesss! adds a rolling monthly option to its contract and prepaid mix (contract, rolling and prepaid), while billing here covers contract and prepaid terms (contract and prepaid).

Who it suits

  • People in Taiwan who want SIM only plans from the network itself, with a prepaid card for shorter stays.
  • Travellers taking an eSIM for data, since eSIM and WiFi calling are both available on this lineup.
  • Long-stay residents who want unlimited 5G data during a contract, and who can check yesss! if a rolling monthly option matters more (contract, rolling and prepaid).

Who should look elsewhere

  • Anyone wanting a rolling monthly option: yesss! sells on contract, rolling and prepaid terms (contract, rolling and prepaid), while billing here covers contract and prepaid terms (contract and prepaid).
  • Short visits that want a month-to-month deal, since contract plans run 24 months; GETESA is worth checking for its prepaid and contract terms (prepaid and contract).
  • Shoppers comparing only the lowest starting figure, since Lonestar Cell MTN lists $0.20 against the TWD 100 prepaid card here, in another currency and market.

Core features

Taiwan Mobile covers the main ways a phone connects on its own network. Sim only plans are available, so you can bring a handset you already own, and an eSIM is offered for anyone who would rather not handle a plastic card. WiFi calling is supported for calls on a weaker mobile signal, hotspot sharing is available for tethering, and 5G sits inside the range rather than being an extra.

Plans and prices

Entry and ongoing cost are two different figures here. The prepaid card starts at TWD 100, a small data bundle bought as a top-up rather than a monthly bill. Monthly plans sit above that: a SIM only plan carries unlimited LTE data, and the 5G plan runs at TWD 1,399, pairing a monthly data bundle with bonus data and unlimited 5G data while the contract lasts. The contract figures are the monthly rates to weigh once the plan is running.

The company behind it

Taiwan Mobile sells as a network operator rather than a reseller, and it is based in Taiwan, having been founded in 1997. That matters for help: support runs on phone and help centre, so a phone call or the online help centre is the route in, with no chat or email option on the list for questions that can wait.

How Taiwan Mobile compares

Frequently asked questions

What does a Taiwan Mobile plan cost to start with?+

You can start small: the prepaid card costs TWD 100 and comes with a small data allowance for a limited period, bought as a top-up rather than a monthly bill. If you want a monthly contract instead, the 5G plan with unlimited data runs at TWD 1,399. Prices are quoted in the local currency, so weigh them against your own usage.

What is included in the monthly price?+

The lineup runs from the prepaid card, through a SIM only plan with unlimited LTE data, to a 5G plan that pairs a monthly data bundle with bonus data and unlimited 5G data while the contract runs. The 5G plan is the one priced at TWD 1,399, and the SIM only option is the lower monthly commitment of the two.

Do I have to sign a contract, and for how long?+

Billing runs on both contract and prepaid terms (contract and prepaid), so you can pick either style. The contract plans are not month-to-month arrangements: they run 24 months, which suits a settled stay rather than a short trip. The prepaid card is the option for anyone who does not want a long tie-in.

Do I need a new handset or a physical SIM?+

No. Sim only plans are available, so you can pair a phone you already own with the SIM or the eSIM. WiFi calling is supported, which helps when the mobile signal indoors is weak, and 5G is available if your handset and local coverage allow it.

What does roaming in Europe cost?+

Roaming in Europe is a paid extra here (paid), not something folded into the monthly plan. If you will spend time in Europe, budget a separate roaming charge or look at a travel eSIM before you commit to 24 months of contract.

Can I share data from my phone?+

Hotspot sharing is available, so a laptop or tablet can be tethered from the handset using the plan's data. The 5G plan is the one to consider if sharing matters, since it carries the largest bundle at TWD 1,399 together with unlimited 5G data during the contract.

How do I get help if something goes wrong?+

Support runs on phone and help centre, so a phone call and the online help centre are the routes in. No chat or email option is listed, which can be awkward for questions that are not urgent. If written help by email or live chat matters to you, compare the alternatives before signing up.

Who am I actually buying from?+

Taiwan Mobile sells as a network operator rather than an MVNO, and it is based in Taiwan, having been founded in 1997. Buying from the network means the coverage, the eSIM service and the help centre all come from the same company, which is a different arrangement from a reseller or a virtual operator.

How does this compare with the other sellers on billing?+

Billing here covers contract and prepaid terms (contract and prepaid). yesss! adds a rolling option to its contract and prepaid mix (contract, rolling and prepaid), and GETESA sells on prepaid and contract terms (prepaid and contract). Lonestar Cell MTN lists a starting price of $0.20, quoted in another currency and market.
