Hey there @Mark ayman You might want to use the International roaming checklist T-Mobile Support page to check some requirements for when you are traveling in other countries. Turn on data roaming and use the enter the name of the destination or country link to check coverage there in Egypt. Unfortunately, it does not look like there is a lot of partner coverage out there. If you are talking about unlocking your phone so you can use an Egyptian SIM card instead of your T-Mobile SIM, you would need to make sure that you meet the eligibility requirements and then follow the unlock steps on your phone. Both of those are outlined on our T-Mobile device unlock support page. 

There is no code/password for unlocking OnePlus devices. It is in the settings on the phone and you can find those steps on that unlock page.
