On many smartphones, dialing this number *#06# will bring up a screen. If you see an "EID" listed, your device is eSIM compatible.
Check Settings:
iPhone: Go to Settings > General > About. Scroll down to see if an "EID" is listed. You can also go to Settings > Cellular to see if an "Add eSIM" option is available.
Android: Go to Settings > Network & internet > Mobile network or Settings > Connections > SIM card manager. Look for an "Add eSIM" or "Download a SIM instead?" option.
Find the EID in About:
For both iPhones and some Android devices, you can find the EID in the Settings > About section.
Check Carrier Lock Status:
On iPhones, go to Settings > General > About and look at "Carrier Lock". If it says "No SIM restrictions," your device is unlocked and ready for an eSIM.
