The Problem

!

International roaming charges can cost $2–5 per minute, turning a short call into a $50 bill.

!

Hotel phones charge exorbitant per-minute rates for both local and international calls.

!

Carrier WiFi calling is unreliable abroad and often blocked by hotel networks.

!

Buying local SIM cards means a different number every trip, confusing your contacts.

!

Many messaging apps require a data plan, which still means paying roaming fees.
