Hi can anyone help, I bought a CECT P168 a few days ago, (quad band and unlocked). It worked with my O2 sim at first, I then tried to used the Data cable to transfer my files, (which didn't work) and now the phone says "Sim Invalid". It won't accept any O2 sims but other sims seem to work.

Did you disconnect correctly?

I read in the manual, that we can get problems when disconnect wrong.

If you have not disconnect it wrong, might be you should try the other slot?

Might be something wrong with the simcard?

The computer didn't recognise the phone as a removable drive it just started to charge it. My O2 sim works fine in my other phone, I've also tried other O2 sims in the phone and they don't work either. I switched the phone off before I connected just like the manual said. Looks like it might be going back on ebay!

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!
