Suddenly this morning I can no longer send texts (get "Message not sent" notification). I thought great, my new phone has broken, tried power cycling, no luck. Next I transferred the SIM card back into my old phone, and it has the exact same problem. I doubt both my phones broke identically at the same time, so what's going on? I can receive texts on both phones no problem.

Hi Steve,

Where are you located at as well? It may be an issue with the network sending your text messages through in your area, or it may very well be your sim card. If you can provide a few more details we may be able to figure out a solution for you.

Original phone (bought from Kodoo) is a Samsung Galaxy Discover, then I recently upgraded to a Cat B15 (bought unlocked from ebay). From my post history you'll see I made the switch 2 weeks ago, and had been using the new phone no problems until this morning. Tried switching the SIM back, but same problems.

Hmm, just discovered I can send MMS but not txt, and also data is working fine.

I'm near Petawawa Ontario, looked here (http://canadianoutages.com/status/koodo) and maybe there's an issue on the network end? Is 'failure to send txt messages' a possible SIM card failure mode?

Keep in mind that MMS requires a data connection in order to send pictures on the network. Text messaging uses the voice network to send them. Now since you have tried pulling the battery and sim card out of either phone to no prevail then I'd suggest try another Koodo sim card in the phone to see if that cancels out the issue, if not then it very well may be an issue on the network side of things. Before switching the sim card though, try calling tech support and see if they can do a switch on the network and see if that helps on their side of things.

When a sim card normally starts acting up you will either get errors on your phone or certain services (network strength, data) will not function properly, it can happen at anytime, whether the card is new or old, some things can be faulty.

Unfortunately I only have 1 SIM card so can't try another :( I tried voice and calling and talking to someone works fine. Going to try tech support now.
