I have a similar problem my P168 which was working on O2, is now suddenly saying "invalid sim". T mobile sims work in the phone and my O2 sim works in other phones, so I know its not the sim. Please someone HELP!!!

Hi the solution is simple , after days of trawling the net for a solution i figured it out myself by ripping the receiver module to bits , the reason why you get invalid sim is because the phone cannot operate 2 simcards on the same frequency , i.e. o2 and vodafone (uk) both work on gsm 900 and you cannot use them together but if you use a t-mobile and a o2 or a t-mobile and vodafone they work fine because t-mobile works on 1900gsm !! , slight design flaw methinks!
