I recently switched to a pre-paid account from being a monthly subscriber. I'm using an unlocked Lumia 925, which has worked very well since I brought it to Koodo as a monthly user. Since the switch, I can't seem to send or receive picture messages, nor can I seem to access any mobile data. I don't know if I had the problem even before the switch, but it has only become apparent to me now. I'm turned the phone on and off, but no help there. Any ideas? Is there a way to check if it is properly functioning? From my Self-Serve Pre-Paid web account, it says I've used no mobile data, and my phone's DataSense tracker shows 0mb data usage. Any help is useful! Thanks!
