Which eSIM is best for 90 days in Southeast Asia?

Airalo Asialink's 50GB/90-day plan at $69 is the best option for a 90-day stay. It has the lowest cost per day, covers 8 of 9 key SEA countries, and has a truly unrestricted hotspot policy, which is essential for remote work.

Can I use my Asia eSIM as a hotspot for my laptop?

Yes, but the rules vary. Airalo allows unrestricted tethering from your data allowance. Saily and Yesim are also hotspot-friendly. Holafly restricts hotspot use to roughly 1GB per day on its Asia regional plan, making it unsuitable for laptop work.

What happens if I cross from Thailand to Laos with my eSIM?

With Airalo or Saily your eSIM switches to a partner network in Laos and service continues. With Nomad, Yesim, or Roamless the regional plan stops working because Laos is not included in their coverage.

Do I need KYC or passport registration for an eSIM in Asia?

No. The regional eSIMs recommended here are roaming-based and are not subject to local KYC laws, so you activate them by QR scan without a passport scan or biometric registration.

Will an eSIM bypass Indonesia's IMEI registration?

Yes. Because roaming eSIMs connect to Indonesian towers via a foreign carrier partner, they are not treated as local SIMs and are exempt from IMEI registration and the IMEI whitelist block.
