T-Mobile Data Usage When On Home WiFi

Hi there @w3wilkes Good on you for keeping an eye on your account and usage details. Does it seem like it is large amounts of data being recorded during the time that you are on your home wifi? There are a few things that I think could be happening. There is a slight delay in when the data is used and when it is timestamped. Since usage can be a continuous thing, the usage details are not tagged minute for minute so you will see chunks used minutes apart. Since you are home and sleeping, I don’t assume this is the only cause, but a variable to consider. The data that registers on network could also be times when the phone is connected to wifi but still pinging the T-Mobile network for software updates, T-Mobile App diagnostics, and other things related directly to T-Mobile and your phone. These shouldn’t be very large amounts of data, but can vary in size depending on what is happening. There may also be times when the wifi network might hiccup causing the phone to default to mobile data. These are just a few possibilities. 

Any data that you see on the usage details screen is considered mobile data and does add up to the monthly usage on your account. I am curious if there is a specific reason that you are worried about the data counting against your account. I like to make sure that all your concerns are addressed, so if you elaborate a bit, I would be happy to help any way that I can. 

Hello,

    I seem to be having an issue with Tmobile tracking my wifi data too. I received a text notification stating that I have used 50GB of data & that they are going to start reducing my speeds. When I look up my usage, I have only used 4 GB of mobile data, but 54 GB of wifi data. I have called Tmobile to ask them why I’m getting a text message stating I have used 50GB of data this month, when it's not their data that has reached the 50GB cap. Their solution was to block the text messages I receive on their end & then I should only truly receive them when the account reached 50GB. This makes no sense to me because their system is obviously sending out that notification for a reason. Their next solution was for me to toggle between mobile data & wifi data. She said to just toggle off of mobile data, so that only wifi data was being used & then she thought it wouldn’t track it anymore. Then when I leave my home or office & no longer have wifi, go back into settings to toggle back to being able to use mobile data. I honestly laughed that this was an option. I am expected to go into my settings every day (multiple times a day) to toggle on & off the mobile data, just so that Tmobile doesn’t slow down my usage, when I haven’t even come close to their 50GB cap on the mobile data? This seems crazy to me. I’m thinking this notification is a glitch in their system, but does anyone have any advice as to how I can get this error resolved? 

I’ve been checking the data usage lately on my wife's phone because I suspect possible cheating. I noticed 28.7753 MB being used at 5:30am while at home on wifi and she usually asleep.

Does that much data usage mean she’s on her phone? I see the much smaller amount of random usage throughout the night that I assume are apps and whatnot operating in the back ground.

Anyone have any info or suggestions?
