    W10 TP is NOT an update. I wish people would stop calling it that. It's a TECHNICAL PREVIEW. It is not meant to be used on a daily basis if you have no other phone.

    If you want to use your phone daily you should go back to W8.1 using this - How can I recover/reset/restore my phone software? - Microsoft - USA

    Read carefully before using as it wipes your phone completely clean. Backup is required.

    Good luck.

    In my case it detects the sim but does not allow to change the data connection to on :(

    Is there a workaround yet?
