Worked examples
Two weeks in Phuket, then Vietnam
Thai 10 GB ($13.20) plus Vietnamese 5 GB ($11.52) = $24.72, or about $22.25 with 10% off for two eSIMs. South-East Asia 20 GB: $27.96. Two separate eSIMs win.
Phuket only
No need for a regional plan: 10 GB for Thailand is $13.20 against $19.20 for South-East Asia.
Three countries, a little in each
Thailand 5 GB ($8.40), Vietnam 5 GB ($11.52) and Malaysia 5 GB ($11.52) = $31.44. South-East Asia 20 GB: $27.96. Here one plan can win, if all three countries are on its list.
Downsides of regional plans
- Check the country list yourself. Before buying, open the plan on Yesim's site and make sure all your countries are there, Thailand included.
- No 1 GB plans, and Asia-Pacific has no 3 GB either, so a short stop means buying more than you need.
- The 15-country Asia-Pacific plan costs more than the 8-country South-East Asia plan at every size. If you do not need the wider coverage, it is overpaying.
Before you buy
- Data only: no calls, no SMS, no local number. Talk to developers through messaging apps.
- Regional plans and the Thai and Vietnamese eSIMs must be activated within 180 days of purchase. The 30 days start when you connect.
- Speed may be limited under the operator's fair usage policy. No ID check, and one QR code installs on one phone.
- yesim.app accepts Visa, Mastercard, Apple Pay, Google Pay, PayPal and UnionPay. Promo code travelpayouts24 gives new users 3 EUR off, under the affiliate programme terms.

For Phuket, is a Thai or an Asian eSIM better?
Thai: as of 22.10.2026, 10 GB cost $13.20 for Thailand, $19.20 for South-East Asia and $22.32 for Asia-Pacific.

Is Thailand included in the regional plans?
Look at the country list on the plan page. Check it on Yesim's site before buying.
Is there a multi-eSIM discount?
Yes, Yesim gives 10% off when you buy two or more eSIMs.
