I just upgraded my phone from the HTC one v and now have the moto g. I have unlimited SMS and MMS messaging included in my plan, and I have never used data (I have WiFi at home and use that instead) my mobile data option has always been turned off (both previous phone and this one) to avoid surprise data charges. Previously I never had an issue receiving or sending MMS messages. Since getting the moto g, I can no longer send or receive MMS messages. This is very frustrating, I am terrible with electronics. How do I fix this so I can enable my MMS without being charged for data?
