Super easy to set up, and the unlimited data was a game changer. No throttling, no hidden fees, just smooth internet everywhere I went!
Check phone eSIM compatibly
iPhone
Go to Settings, then General, then About.If it says "No SIM restrictions" under Carrier Lock, your phone is likely unlocked and can support eSIM.
Android
Go to Settings, then Connections, then SIM Manager. If you can add an eSIM, your phone likely supports eSIM.
Look for an EID number
Collect *#06# then press Dial button, if there is 32 digits of EID number your phone is compatible with eSIM.
