Sorry, no solution - just some added info. I have the same problem with a Palm Centro. Changed sim card (O2) but no improvement. Palm eventually replaced Centro, but fault persists. Anyone with similar problems / solutions?

If the problem repeated when you swapped your SIM card to another phone, it rules out it being a hardware issue. You can take your SIM card to a cellular store and have them replace it. That should fix the issue. I doubt it is the card itself since the card simply holds your account info for accessing the network. It sounds more like an issue within the network where the internal settings associated with your SIM # weren't properly set. Getting a new SIM card will force the system to fully set and associate your account with the SIM and should (fingers crossed) help fix the issue. Good luck!

palm treo 755p doesnt have a sim card tray!

sorry

set different ring to different callers.

need a puk code for my palm treo 750

If all contacts are on computer, I'd pull out sim card and do a hard reset:

The SIM card is dirty or scratched.

Try taking the SIM out and wiping it with a dry cloth... then insert it back in firmly. If that does not work, you may need to replace the SIM card, or find a way to get it to press itself more firmly against the phone.
