I just got a 35$ monthly plan yesterday with an iPhone. It says unlimited sms and mms is included, so this means I can text and send and receive picture texts as much as I want without being scared I'm going to have a huge bill right?
Yes however your data connection needs to be on to send and receive mms which could incurre charges from other apps running in the background. To avoid this you can go into your settings and under data usage choose to restrict background data. You will not recieve notifications from your apps through your data connection however and will have to open an app to see if you have any notifications unless your on wifi then everything will work as normal.
