Hello,
I am currently travelling within the EU (France) with my German O2 phone.
I am trying to send an (urgent) SMS to a French contact.
I keep on getting error 38 message, and the SMS cannot be sent.
Note : I have 4g reception, I have tried with and without wifi.
I have reset all the settings of mobile data.
Can someone please help me (as it is impossible to reach someone from O2)?
Thanks a lot in advance for your support!
