Why am I getting an "Invalid IMEI" error when registering myFirst Fone S4?
The "Invalid IMEI" error occurs because the myFirst Fone S4 is an eSIM device. eSIM activation must be done through the myFirst Circle app and cannot be activated via the FreeSIM website.
To activate your eSIM on myFirst Fone S4, please refer here: Activate myFirst eSIM on myFirst Fone S4.
