I'm having some problems with my mobile data connection which is likely to be a network issue, but just wanted to check if it could be down to my phone. I've had the phone a few days, and mobile network connection certainly was working when I set the phone up. I've since been using wireless which works with no problems. Today i've tried to connect using the mobile network and get an error message. Also, when I try and switch on the mobile network connection in the settings/wireless and networks menu, i get the message 'trying to connect' beneath mobile network and the option becomes greyed out and stays that way. The only way I can force it to stop trying to connect is by going into airplane mode. Anyone else experienced this?
