Can't send text messages with Dash s620

[Guest swj]

I recently bought a new unlocked T-mobile Dash off ebay and I really like it except I am unable to send text messages. When I try it says:

"The following errors occurred while sending and receiving messages: ------ Your text message cannot be sent."

Does anyone know a fix for this?

I am using it with cingular prepaid, wm5.

I have a similar problem on Rogers if I don't provide the area code in the contact.

After calling Cingular and T-mobile tech support I got this fixed. I had to: 1. change the call center service number under settings.phone and 2. change the SMS Service to GSM Preferred under settings.connections
