01

Arrival and immigration

Airports in these countries may have free wifi, but it is often time-limited or requires a phone number. Having data helps with e-arrival cards and transport bookings.

02

Cash and payments

Cash is still common in many places, especially markets and small vendors. QR payment apps are popular, so data is useful.

03

Local SIM registration

Each country has its own registration requirements for local SIMs, often involving passports. A regional eSIM avoids dealing with multiple local SIMs.
