Phone says no sim inserted


    Can someone please tell me why my phone is all of a sudden saying no Sim inserted when it is inserted correctly. It has never done this until today.

        SIM went bad?  Not likely, but possible if it's old.

        Phone's SIM slot went bad?

        SIM somehow shifted? (this is likely if you put a smaller SIM than the device requires in)

        Or, the weird thing my tablet did -- it just wants you to toggle airplane mode?


        There's a large number of possibilities it could be.  The easiest troubleshooting is to take a SIM from another device and swap to see what happens and help you determine the exact cause.  If you don't have a friend or family member with T-Mobile and the same size SIM your device requires, you can go to a T-Mobile store and they can help troubleshoot.

          Hey mjlongbine - we definitely stand behind smplyunprdctble's input here.  Is your phone still giving you this error message?  Were you able to try the test he recommended?
