Phone access affects maps, banking, airport transport, landlord messages, delivery apps, two-factor authentication, and emergency calls.
Set up connectivity before arrival so you are not solving it while tired at the airport.
An eSIM is often best for the first few days. A local SIM or local plan may be cheaper for long stays.
The best setup is often both: arrival eSIM first, local plan after you understand coverage and requirements.
Before changing numbers, check which accounts use SMS verification. Banks, email, tax accounts, payment apps, and work tools can lock you out if you lose the old number too early.
Keep backup codes and recovery email access ready.
