Data Usage Discrepancy


Ever since I switched out my Sprint SIM card for T-Mobile's, the amount of data usage the carrier thinks I use is almost exactly double what my phone is telling me I use. I suspect the phone is more accurate because I've never used as much mobile data as they're claiming I am now using.

Support was no help and didn't even seem to understand the problem. Any ideas?

What your carrier sees as data use and what the device sees as data use can be very different amounts.

In fact, the device will actually tell you this.

Thanks for that info. I am curious why the large discrepancy though.

Mostly because of how devices use data in the background is my guess.

Also, your device may not account for some of the tracking, pinging, and other connections that the carrier does with your device.
