eSIM or a local SIM card in Asia?
Across Asia the eSIM wins on borders: one plan keeps running in all 20 countries and needs no registration, while local cards mean a new purchase at each frontier and passport checks in places like India or China.
| Feature |  Simbye eSIM |
Local SIM card |
|---|---|---|
| Crossing a border | Nothing to swap, the plan keeps running in all 20 countries | Buy a new card in every country |
| Setup | At home before you fly, with the QR code from your email | At the airport or in a shop, often with a queue |
| ID and registration | Not needed, you travel on a foreign plan | Required in several countries, among them India, China and Saudi Arabia |
| When you get online | As soon as your phone finds a network after landing | Only once you have bought the card |
| Your own number | Stays active in your phone as a second line | Takes the card slot – with only one slot, your card has to come out |
| Local phone number | None, this is a data-only plan | Local number included, handy for delivery drivers and callbacks |
| Hotspot | Allowed, laptop and tablet can share it | Allowed on some plans, the terms are usually only in the local language |
| Data and validity | 1GB to 20GB, 7 to 90 days, fixed before you travel | A new package in every country, top-ups often cash or local card only |

Frequently Asked Questions about Asia eSIM
Data, calls, real phone numbers, top-ups and setup — everything you need to know before you buy a Simbye eSIM.
The Asia eSIM is a profile that covers twenty countries, from Japan and South Korea through Thailand, Vietnam and Indonesia to India and Australia. You buy once and use the same eSIM in all of them, and you change nothing at the border. The full list is on this page.
Yes, the eSIM does work in mainland China, with mobile data there too. But Google, WhatsApp, Instagram and similar services are blocked in China. Whether a foreign eSIM changes that depends on how your traffic is routed – do not count on it. Set up a VPN before you fly. The block does not apply in Hong Kong or Macao.
No, Taiwan is not included in the Asia eSIM. Taiwan is not one of the 20 countries in this plan. Laos, Myanmar, Nepal, Bangladesh, Bhutan, the Maldives, Brunei and Mongolia are not included either.
How much data you need for two weeks in Asia depends on use: 5GB over 30 days covers maps, chats, bookings and occasional social media for most people. If you stream video or make daily video calls, take 10GB; for a long weekend 1GB to 3GB will do.
No, you can't make calls or receive SMS. This is a data-only plan without a phone number. Calls and SMS codes keep going to your usual number as long as you leave it in the phone. Calls through WhatsApp or FaceTime run over data – though in some countries those calls are restricted.
No, no need to register with a passport. You are travelling on a foreign plan. The registration rules that apply to local SIM cards in countries such as India or Saudi Arabia do not apply to you.
The eSIM that is best for Asia starts at 4,95€, and it depends on how many borders you cross. One regional plan across 20 countries saves you switching at every stop, while a single-country plan usually gives you more data over the same trip. This one is data only, no local number, riding local 4G and 5G. Strong in Bangkok, Tokyo, Seoul and Singapore, thinner in rural areas and on small islands.
