Mobile Data Shows PLMN instead of cellular provider
my iPhone is showing the PLMN (the mobile country code) instead of the actual name of the provider for the Mobile Data network(for example it shows just the number 262-01 instead of (germany)telekom or 262-02 instead of (germany)vodafone , I tried updating to current IOS, reseted settings and network settings...didn"t help. I alsotried to insert the sim card inside other iPhone, the issue is not shown there.
How can I make it for the Mobile Data Cellular providers to be shown with names and not with the code?
