I've double and triple checked all APN settings and they are match what Koodo provides. My mobile data is working fine, and everything else on the phone is functioning as intended. The error message I get from ChompSMS is "Can't download MMS, check your APN settings". I just don't receive anything in the stock messaging app. I'm not sure how to go about resolving this issue. I have recently upgraded an Android version 4.4.2 Thanks for the help, if anyone can help me.
