CoreESIM profiles are designed to operate as a local data service, completely bypassing your primary SIM's international roaming tariffs. Given that Andorra is outside the EU/EEA free roaming zone, a standard home mobile plan would trigger significant per-megabyte charges. By utilizing your CoreESIM, your data consumption is pre-paid and managed, ensuring you connect through local carriers like Andorra Telecom at a predictable cost, effectively eliminating bill shock.
