On my FP3 /e/. There’s an empty program called the Sim Tool Kit. There’s nothing in it, just a blank window.
Depends on your SIM card provider.
I have a Telekom SIM card, and SIM-Toolkit for me lists some mostly useless online service offers from Telekom, apart from some perhaps useful account info queries.
That is possible that my provider does not provide this for me. Thanks for your answer.
I remember that there were entries in Fairphone 1, but with a big sim card.
For Orange/Sosh (France), this app is mandatory to enable the proprietary “Mobile Connect” 2FA.
