Phone specs out of the way first: GT-i9300, Android 4.3 (via OTA), sim unlocked, not rooted, Baseband i9300UBUGNF1, Kernel 3.0.31-2320216, and the IMEI matches the frame.
So I've got a problem that's very similar to a lot of other people with one or two exceptions. I get the "Mobile Network Not Available" error message and I've tried the suggested fixes except for the Ariza patch and I haven't tried changing my modem. I don't want to jump into either of them yet because I'm not sure my problem is the same as all the others. Here's why:
When I go to set the network manually via Settings > More Networks > Mobile Networks > Network Operators > Wait till your device is searching for operators. Once the search is done it will showa list of Network Operators ... Nope, not mine. Mine shows nothing and goes right back to the menu showing Search Networks and Select Automatically. Tapping Search Networks brings the same result. If I set the Network Mode on the previous menu to GSM only, it takes less time to search, but still returns nothing.
Also, I don't have any bars. Not as in having bad signal, but as in there is no signal strength indicator in the status bar. Instead, I have a circle with a line through it next to the battery level indicator. I can not even make emergency calls with the phone.
I haven't found anyone with this particular problem yet, even though I've been searching all day. Perhaps I'm not searching for the right thing?
I've tried an old ATT sim and an active GivMobile sim, both with the same results. Both sims will register networks on other phones. I started out on 4.1.2 and did the OTA updates to get to 4.3 with no change in symptoms. I did a factory reset before doing the updates. I've never had a custom ROM on the phone. The IMEI doesn't show up as blacklisted on any site I used to check it. I even went as far as replacing the SIM card reader.
Could my antenna be bad? Could I have the wrong modem for the networks I'm trying to get onto? Any opinions or direction would be greatly appreciated.
