Then I tried another sim card from T-mobile, and it worked on my Passport. I don't know why my nano sim card worked on other phone but didn't work on my Passport. And I don't know why my Passport worked with another sim card but not the new one I got.
then I came to T-mobile store and replaced the sim card to take the new one. Now, it worked on my Passport but when I came home, it still "SIM not detected". I took out then put the sim card again and I had signal. Many times the Passport doesn't get the signal of the sim card, I have to take the sim out for a while and plug it in later. Is it phone problem or OS problem?
