9900 getting no signal!

For the past week, my BB9900 has been getting no mobile network signal (SOS) therefore I cannot call or text whatsoever or use the internet when I'm out of the house. I am with EE (Orange). Phone has no trouble connecting to Wi-Fi. About a month or two ago the same thing happened for around a week then one day when I got on a bus it started working again. Strangely, when I turn the mobile network off then on, it gets 4/5 bars of signal for 1 second but does not display EE, then it switches straight back to SOS. Obviously this is causing serious difficulty, no point of me having a phone right now. Please help.
