Why an eSIM is Essential for the United States
International Roaming Doesn't Work
Unlike Europe, the USA has no free roaming agreements. Using your home carrier in the US costs between $5 and $15 per MB - a bill that can reach hundreds of dollars for just a few days.
Benefits of a USA eSIM
- Massive savings: 10 GB for $8-15 vs $100+ in roaming
- Nationwide coverage: access to all 3 major networks
- Instant activation: connected as soon as you land
- No airport queues: skip SIM kiosks at the airport
