Mysterious cellular data usage in early morning
This is happening to me over the last 6 months and they refuse to look into it and say that we use the data. We have unplugged the hotspot to make sure that there isn't anyone hacking the data. When the device is unplugged it continues to show data usage at 6:30 am when 1. nobody is in the office as this is a business hotspot and 2. the device has been turned off. Customer services has been a nightmare. They insist that we used our data and that we can upgrade. We have upgraded despite knowing that we aren't using the data, but I refuse to continue the upgrade as the data usage is not us. Tmobile needs to look into this because it's ridiculous.
It turned out that it was not a T-Mobile problem but my iPhone setting problem.
To avoid those unnecessary internet access from iPhone, you should do:
Settings->Cellular->Cellular Data Options->Data Mode->Low Data Mode.
Default setting of the data mode, “standard” allows the IPhone to access the celluar network to do some kind of bookkeeping functions.
”Low data mode” blocks it.
I seem to be having this same problem. Last night I turned off my Samsung 5G Flip at about 9:00pm then turned it back on today at about 6:00am. My account shows useage just after 3am. How can this happen? Is this from T-Mobile being hacked?

Thank you! I appreciate your response!
Hey there! I am very sorry you are having so much trouble with your hotspot! What kind of device is it exactly? Can you try taking the SIM card out of the device and letting us know if the usage is still occurring?
SIM Card is out. It's a ZTE on the sim TM9260
When did you take the SIM Card out of the device? Has there been usage while the SIM card was out of the device?
Hi, no I just took the SIM card out after I saw your message. I can tell
you that the device was unplugged and turned off during the hours that the
data was being used. Again, this started about 6 months ago. If you go into
my account as I told the customer service reps you can see that I barely
used data and then all of a sudden there were spikes in my data usage when
I was not in the office, not utilizing the data and/or the device was
unplugged and turned off.
We are unfortunately unable to access your account here on a public forum 😥 All data recorded on the network comes from your SIM card. If the SIM card is out of the device and there is still active usage, you can let our tech care folks over the phone know the specific times you had the SIM card out of the device and they can compare that to the recorded usage.
I have found with past carriers TMobile included that usage statistics can lag behind the actual use time frame. All depends on when the network and Towers report usage. They don't report the time it was used just the time it was reported.
So there has been no usage since I took the sim card out. Why would the sim
card still show data usage when the device is unplugged or turned off as we
were doing when we started seeing strange data usage.
