As someone might know, no SIM card work on my pre3. I almost tried more than five SIM cards, from O2, Orange, 3-Mobile. They are all unlocked and none of them works on my phone ---- always showing "sos-only".
I have to ask Palm Europe serivice for a replcement or even refund. I could not stand for this any more -- even if HP have already gave up this device.
But I am not sure if Palm Europe would be happy for this -- of course, they are not happy.
I will update what I get from Palm.
