Is anyone else have data overages with their new phone, even with the LTE being shut off

I have upgraded to the iphone 5s about 3-4 months ago, and my data usuage has gone up and over within 2 weeks of the billing cycle. with my old iphone it never went over the 4g limit, and that was with nike + and pandora running apps loaded [im a runner and have done this with 3 half marathons in one month plus additional miles]. i am now afraid to even use pandora for an hour on my phone. I have turned off as many things as possible to lighten up the data usage, ie LTE is off, and so is a lot of location servces and background app refresh. i still cant figure out why im reaching my max data usuage so quickly when i am using it 80% less than i use to.

is anyone else having similar issues and has anyone found a solution to this?

i have also done a factory reset on my iphone to see if it helps at all - since, that is apples answer to everything.
