All three sell prepaid SIM cards to tourists, usually requiring in-person purchase and passport registration.

A Practical Alternative to Local SIM Cards
While local SIM cards work well, they come with a few drawbacks:

Airport queues after landing
-
Passport registration
-
Store visits during business hours
-
Language barriers during setup
Some travelers prefer to avoid these steps entirely and use an eSIM instead, especially for short trips.
