The 7-day math
An international roaming pack costs ₹2,999 for 7 days. A Thailand eSIM with 15GB costs ₹350–500.
- Keep your Indian SIM active for OTPs (SMS roaming is usually free to receive)
- Install the eSIM before you fly, activate on landing
WhatsApp calls work fine on hotel Wi-Fi — you rarely need minutes at all.
