I bought an S23 from O2 Germany about a year ago and have been using it with two German SIM cards since. I took a trip to the UAE last month, and I couldn't use my phone with a du SIM card. Everything I read says that I have to use my phone in Germany for one hour before I can use another SIM card. The du SIM card was activated and worked fine with my other phone. Is there any solution to unlock my phone?
