As is says above. I've put in a 3 PAYG sim, attracted by the low charges. I'm not sure whether I'm pleased with the change. Coverage was supposed to be OK at my location on 3G and Good on the Enhanced H systemThe mobile network type shown in 'About Phone - Status' is hunting between 3G and H, but that may be due to the geography round here. In looking around I noticed that in 'About Phone - Status' phone number is Unknown. I've seen by searching that it may be possible to correct that using another phone with the facility to modify the SIM. Is it possible to do on the G300?
Is there anything to be gained, performance wise, by changing the ROM? Is another ROM more suitable for use on the 3 network?
