    Since yesterday my girlfriends Samsung Galaxy S3 started showing a forbidden sign on the place in the notification bar which normally shows the network bars. When I try to make a phone call it says "Mobile network not available" and when I go to Settings > More > Mobile networks, it says "Insert SIM card to access network services". I think this started with that *(#&$(*@# Gmail update which first put her phone in a reboot loop and later on made it so slow you had to litterally wait 5 to 10 seconds after every touch input. But she disabled and enabled a couple of services, after deleting all Gmail updates and the phone was back to normal. But now she can't make any phone calls............

    What I did to try to fix this:

    • Reboot the phone
    • Turning off the phone and removing the battery
    • Putting the SIM in another phone: the SIM works
    • Putting another SIM in the S3: still no network
    • Cleaning the SIM with a cloth
    • Putting a piece of paper between the SIM and the slot to make sure the pins are connected
    • Wiping cache
    • Disabling and enabling system services
    • Checking if services were disabled that should be enabled
    • Updating all unupdated apps


    Does any of you have another solution? I see a full wipe and restore only as an ultimate measure, so I'd rather try some other experimental things first.

    Thanks in advance!

    Since I have no way of knowing what other system services may still be disabled (the phone is rooted?) I could only suggest a Factory Reset.

    If you're using the right tools it should only take a half hour to get the phone back the way you like it.

    I haven't rooted the phone yet. Also, I've enabled every service / process / app that was disabled, rebooted, wiped cache and still no luck.

    Well, I've just done a full wipe and factory reset and no luck I guess that only leaves a hardware failure. That's the second broken S3 within a year (the first one had a defective camera).

    As a last resort you could use the Kies software on your PC to reload the firmware. Hard to imagine that something in the OS got screwed up by a Gmail update; perhaps it was just a coincidence.

    Sadly I have no luck in getting the S3 to connect with Kies on a Windows 8 or Mac computer. File explorer kan browser all files on the phone, but that useless Kies won't connect. It keeps on saying "connecting" and then finally gives the notifications "Device not supported".

    EDIT: so Kies did connect with Kies over Wifi.... but guess what Kies on my PC says? No Sim card inserted. Unable to continue communication...................... Are they serious?!?!

    Well, you can't load the firmware over Wi-Fi, so I guess it doesn't matter.
