How to get connected
At the airport, follow signs to the telecom kiosks, show your passport, and choose a prepaid package. For eSIM, purchase the profile online before arrival, install it via QR code, and enable data roaming.
If you travel by train on the north‑south corridor, 4G coverage is reliable; otherwise, keep a backup SIM for rural areas where signal can be spotty.
Wi‑Fi and other tips
Wi‑Fi is common in hotels, guesthouses, cafés and some airports; speeds are modest and often require a password from staff.
Turn off automatic roaming to avoid surprise charges, and set your phone to 4G/LTE only.
Consider a power bank; charging outlets can be scarce in remote guesthouses.
- Check Wi‑Fi availability on hotel booking pages.
- Use Google Maps offline maps for navigation without data.
- Keep a copy of your passport registration receipt for SIM activation.
