When I make a call with my FP4, it appears that my caller identification is hide (unknown number). Given that I did not had this issue with my previous phone, I assume there is a default mode on the FP4 to hide the caller ID. However, I am not able to find any setting that could change that.
I went through the options of the Phone app, but I did not find any “Show your caller ID” option.
In case it’s not an issue with your carrier, the setting you’re looking for is indeed not easy to find.
Open the phone app and tap the menu in the top-right corner (three vertical dots), select “Settings”.
Then go to “Calling accounts” and tap on your carrier name.
Then go to “GSM call settings > Additional settings > Caller ID” where you can select one of “Network default”, “Hide number” or “Show number”.
