I'm getting the dreaded 'Emergency calls only' issue on my Galaxy SII. It was working absolutely fine for about 3 months, then it suddenly stopped connecting to the Vodafone network. When I try to connect manually I get the error "Unable to connect. Try again later". The Sim works fine in other phones. I can see the Vodafone network (and others) when I search for it. I get the same error trying GSM only, WCDMA only and GSM/WCDMA (Auto) I'm currently running rooted 2.3.6 (XWLA4) with the XKI3 baseband. I have tried: Pulling the battery and sim and leaving for several hours Manually entering flight mode and back using the *# codes to switch network mode and turn the radio on/off Re-flashing the Radio Checking my Imei and CSC Checking the sim socket for debris damage. Nothing seems to work! Unlike others with this problem, I have not been able to connect to the phone network since this issue started (wifi is fine). Please - someone must have an idea as to what causes this and what can be done? I'm going to try ICS when the Vodafone one comes out and see if that helps, but I have my doubts! I will be trying a factory reset later.
