I've had a 4GB plan for several years now and went over maybe once or twice this whole time. Then out of nowhere last month I started going over my data well before halfway through the billing cycle. I looked up my data usage and my Message+ app had used nearly 4GB of data. By the end of the billing cycle it had used 7GB! In past billing cycles I can see that on average the Message+ app used not even 0.1GB of data. I haven't made any changes in the app or to the settings on my phone. I haven't done anything new recently and can't figure out what is causing it to use so much data. I've changed the settings on my Galaxy S7 (not a new phone, had it for almost 2 years) to restrict background data although the majority of the data being used by this app is displayed as foreground data. Any insight would be greatly appreciated!
