I have had my MPX200 for some time, but do not send SMS messages very often. I receive them fine, but I am no longer able to send them from the phone.

Would the fact that I have ActiveSync setup to sync with my Outlook make any difference? I honestly think I sent messages before, and that this is something new. I am using T-Mobile if that makes any difference.

Any assistance appreciated!

I am having this same problem... I was able to send SMS message without any problems for the first few months after I got my phone, but I have since performed a Master Reset, and now I can only receive messages. I have performed a Master Reset before, and was still able to send and receive SMS messages, but I have had no such luck this time....

Mine seemed to "self-correct" after a couple days. I didn't change a thing, and all started working again. I am using T-Mobile service, and not sure what you might be using. The same thing happened for MMS messages, didn't work for a few days, but then started working and has worked ever since all on its own. Go figure.

Good luck on yours - and hope it self corrects. If not, you might try the master reset and resetting the phones settings for your service provider.
