Is there an email interface for this so you wouldn't have to pay for each SMS? I get unlimited email, but have to pay for each SMS.

Bad news civicmon. I think I did the definative experiment. Sent a message to Google SMS on my monthly billed TMobile phone, it worked fine. Pulled out the SIM and put in a prepaid TMobile SIM and sent the same message. It came back with a "Prepaid Service Error" message. They do seem to be blocking it.

Yeah.. i found it out today because T-Mo 2 Go blocks all shortkey phone #s for some bizarre reason.

I clicked on this thread to update that. Weird that it worked when I first got the phone but when my phone # was re-assigned from my old phone to my new one, it stopped working. Thought it may be related but it doesn't seem likely.

Thanks for trying, nonetheless. :(

if it mean anything, www.synfonic.com is the same thing, but their replies are SO slow...
