I am on a 20GB plan alone through my parents. I work in an office without wifi and I text moderately throughout the day, send and receive pictures with friends, etc. I browse Instagram on and off..maybe 3 times an hour. I was streaming podcasts via YouTube that can sum up to 2 hours worth of audio and video. Our pay period ends the 26th or so and last month I was accountable for 17GB. **I havent deleted conversation threads in maybe a little over a month or two but on the "Details" tab on some convos with friends the photo exchange can be up to 2,200. Does it cost me data to receive photos from others even if they have an iphone?? I dont know what my settings should be but I have since shut off Cellular Data on Tumblr, Instagram, Chrome, Youtube, App Store, etc. and at the top I turned off Enable LTE (left Cellular Data on). When I am at home, I am automatically connected to WiFi. However, do I need to turn off Cellular Data too when I am connected? I reset my statistics in Settings for Data Usage and so it reads as this: Last Reset: January 7th, 2015 3:10pm Cellular Data Usage Current Period: 738MB Mesaging Services is at 237MB Instagram: 116MB Chrome: 106MB Tumblr: 56MB Largest ones consuming most data. Why is Messaging so high? Is it just a simple restraint I need to set on myself and not use Chrome/YouTube for watching and listening to podcasts? Instagram and Tumblr dont account for a lot of megabyte usage.. I think I'll invest in an audio cable to run from my computer for headphones. Any advice would be appreciated!
