Questions?
See all FAQs →How much does a United States eSIM cost?
Masteresim plans for United States start from $5.22, depending on data size and validity. Prepaid, contract-free, and the price you see is the price you pay — no roaming charges.
Which networks does the eSIM use in United States?
Your eSIM connects to Verizon, AT&T and T-Mobile on 5G, and your phone automatically picks the strongest signal. Hotspot / tethering is supported.
How do I get my United States eSIM?
Buy online and your QR code is emailed within seconds. Install it over WiFi before you fly, switch the line on when you land, and you're online in minutes.
Will my phone work with an eSIM?
Most phones from 2018 on support eSIM (iPhone XR/XS+, recent Samsung/Pixel). Your phone must be carrier-unlocked — dial *#06#; if an EID shows, you're set.
When does my plan start?
Validity begins when the eSIM first connects to a network at your destination, not when you buy. Install at home over WiFi and activate on arrival.
Can I keep my own number?
Yes — the eSIM runs alongside your physical SIM, so your number stays active for calls and texts while the eSIM carries your data.
