FAQ: USA eSIM
Does the eSIM work in all 50 states?
Yes. T-Mobile covers all 50 states including Hawaii and Alaska. Coverage is strongest in urban areas and along major highways. Remote national park areas may have limited service.
Can I use it for Uber, Lyft, and Google Maps?
Yes. All apps work normally with your eSIM data connection. Navigation, ride-hailing, food delivery, and social media all function exactly as they would on any US mobile plan.
Do I get 5G speeds?
Yes. If your phone supports 5G, you'll connect to T-Mobile's 5G network automatically in 300+ US cities at no extra cost.
Can I get a US phone number too?
Yes. Simbye offers real US mobile numbers starting at $14.99/month. Perfect for receiving SMS verification codes from US services like banks, Uber, and DoorDash. Your number works on a real cellular network — not VoIP — so it passes all verification checks.
What's the difference between unlimited and capped plans?
Simbye's unlimited USA plans ($20/7 days) offer genuinely unlimited data with no throttling. Capped plans (1-50GB) are cheaper and ideal if you know your usage. Not sure? Start with the free 100MB trial.
