Help Can't send pictures attached to texts

[DarkSky]

Just found this out... I'm on Telus (in Canada) - I can't seem to send a picture attached to a text. Worked fine on my Droid (Milestone).

Now it just keep saying "Currently unable to send your message. It will be sent when the service becomes available"

I know my carrier is available because I'm showing 3 bars, and have send 3 regular texts to the person already.

???

It's either not supported by your provider, or you need to check your mms/apn settings from your providers site.

Ok, but why would it work before? It worked the first time I tested it a few days ago. I didn't send anything for the last few days, tried today, and it doesn't work ( ? )

'Seem to have found the problem.

Settings > Wireless and Network > Mobile Networks > Use Packet Data

.. my box was unchecked. I checked it, and it says that using it may incur extra charges. 'Called Telus and asked, answer was it doesn't cost anything extra.
