Our verdict on each
Chunghwa Telecom
Chunghwa Telecom is a carrier roaming plan rather than a marketplace eSIM, and it suits travellers on short or long trips who want a set daily allowance instead of streaming. Prices start at TWD 388, and support runs through phone, chat and email when a plan needs adjusting.
O2 Espana
O2 Espana sells carrier plans, not travel eSIMs, so it suits anyone already on its home network who wants a single plan for trips abroad. Plans start at €5, run on Telefónica with 5G, and carry a fair use policy instead of a fixed travel data allowance.

Pros and cons
Chunghwa Telecom
Pros
- Prices start at TWD 388, with the Japan and Korea bundle at TWD 588.
- Support covers phone, chat and email, so help reaches you outside a single channel.
- Top-ups are available, so a longer stay can be extended without starting over.
Cons
- Hotspot sharing is listed as no, so tethering a laptop is out on these plans.
- Unlimited data is listed as no, so heavy streaming needs a larger bundle.
- The fair use policy slows speeds once the daily allowance is used, and tells customers to avoid long video streaming, hotspot sharing and software updates.
O2 Espana
Pros
- EU roaming is included at no extra cost with reasonable use under the fair use policy.
- Runs on Telefónica with 5G, so home phones behave the same on a trip.
- Help is available on chat, email and help centre.
Cons
- Unlimited data is not part of the offer, so heavy users sit inside fair use limits.
- A fair use policy caps data in the first roaming zone, with usage past that point billed per GB.
- As a carrier plan from an operator headquartered in Spain, it is built around an existing home line.

Questions about each
Chunghwa Telecom
How much does a Chunghwa Telecom roaming plan cost?+
Prices start at TWD 388. The bundle covering Japan and Korea is TWD 588, and the range is sold for both short trip and long trip, so a longer stay can be planned with top-ups rather than a new provider.
How much data do I get on these plans?+
Data comes as bundles by the gigabyte, with the Japan and Korea option at TWD 588. A fair use policy also applies: once your daily allowance is used, speeds are slowed and you are told to avoid long video streaming, hotspot sharing and software updates.
O2 Espana
How much does O2 Espana cost?+
Plans start at €5. That entry point sits above the €5 site median, and the price ranks 149 of 313 compared brands, so the value depends on what is already on the bill.
Is data unlimited on O2 Espana?+
No. Unlimited data is not included, and use sits under a fair use policy: EU roaming is included at no extra cost with reasonable use, while mobile plans face a cap in the first roaming zone before data is charged per GB. Its short trip and long trip focus fits ordinary travel use.
