Im no expert on these data plans or anything techie really. I had the unlimited plan with verizon,lost it with the upgrade. Im at 6gb a month so is wife. I barely go online to facebook and youtube but i go through my plan apparently in only a few days. So i've been turning off the mobile data icon on my phone and not going online unless im home where i'll connect to my wifi. But when i want to send texts or receive any that include images i can't, it says i need mobile data turned on. Can someone explain why i can't send pics in a text without and not wifi? Is there a way to check to see how much data i might be using unknowingly even with the mobile data off?
