American traveller's complete guide to travel eSIMs in 2026

Stop paying AT&T and Verizon international day pass fees

AT&T's International Day Pass is $12 per day. Verizon's TravelPass is $10 per day. For a three-week trip that's $210–$252 just for your phone.

Travel eSIMs are a better option for most American travellers. Here's everything you need to know.

What is a travel eSIM?

An eSIM is a digital SIM card built into your phone. You scan a QR code and your phone connects to a local network at local prices — not US carrier rates.

Which American phones support eSIM?

All iPhones from the XS (2018) onwards support eSIM. iPhones sold in the US from iPhone 14 onwards are eSIM-only — no physical SIM tray. Most flagship Android phones from 2020 onwards also support eSIM.

Check your phone is unlocked

US phones on carrier payment plans may be locked. Contact AT&T, Verizon or T-Mobile to unlock before purchasing a travel eSIM. Most carriers unlock after 40–60 days of active service.

Why buy from an Australian provider?

Proost plans are priced in AUD, which is weaker than USD — so you pay less in dollar terms than the listed price. All purchases are also covered by Australian Consumer Law regardless of where you live.

Keep your US number active

When you add a travel eSIM, your US number stays active. You can still receive calls and texts. The travel eSIM handles data only.
