I called T-Mobile support about this, but they really didn’t have any answers for me, so wanted to see if anyone else had experienced anything like this.
My TM 5G Home Internet usage skyrocketed without any change in our household’s usage behavior during this current billing cycle (May 2023). We have the Nokia 5G21 Gateway. In March we used 66.55 GB, April was 9.23 GB and May is 417.31 GB.
I’ve checked all the devices connected to our home network and have been able to identify them all, so I don’t think anyone is tapping into our network. We aren’t experiencing any decrease in speeds or dropping of the network, so maybe I don’t have any reason to be concern, the jump in data usage was just alarming, since we only really web browse, stream video and connect smart home devices. We don’t do anything that would send massive data outwards, either.
A few things I noticed in my usage reports over the last few months was the number of reports jumping from 8 in March and 1 in April to over 3,000 in May. Also, the previous reports showed as “Mobile Internet,” whereas May’s report shows all as “Internet Access.” So those were both odd.
