Hi, I'm trying to send SMS message from my 6620 (not via PC suite) and it fails.
I tried restarting the phone, as well as reconnecting the batterie with no luck . I can see the message icon on the top but it stays there until a "Message send failed" pops up . Tried to delete the cache using PC suite, no success .

I used to be able to send messages but it stopped sending a few days ago.

Any idea how to get it fixed ?

Just FYI, I just formatted the phone using the instruction in the respective sticky thread, and I'm now able to send SMS . This is after I've spent 30+ minutes on the phone with Cingular tech service with no luck.

Cheers .

make sure you have the correct messafe center number, the option can be found in messaging, options, text message ask cingular for the correct "Message Centre Number"
