Why does my mobile hotspot disconnect every 5 minutes?

What plan do you have and what is your hotspot thresh hold?

I am on the Magenta plus plan and I have 30gb of hotspot data and I haven’t used even half of the data. 

Does it only happen in one spot/area?

No. Multiple areas of my home. 

Hey, was this resolved for you? I've been having the exact same issue since starting to work from home due to the pandemic. Some days I have no issues at all and then the next day it's constant.

No it was not. It still happens all the time. 

Any update on this from anyone? I got back to NYC after 5 months in Puerto Rico and Mexico where I was using my cellular hotspot on my iPhone X on T-Mobile and Telmex networks respectively. Even when the signal dropped to one bar of LTE or even 3G, the speed and connection was well stable to both of my laptops,  Macbook Air (Intel, Mojave), and my X1 Carbon (Windows 10). As soon as I was back on the T-Mobile network in mainland US, my hotspot has not worked properly since. Constant dropouts every couple of minutes and that is whether any of my devices can even find the network despite being on full 5G or LTE Signal. I'm on the Magenta with and extra 20GB of Hotspot data per month, too. After trying everything and speaking with T Mobile multiple times and for hours, there has been a ticket sitting with their tech team for over a week. They called back the other day asking if I have seen any changes, which I haven't, but would not tell me what they even attempted to resolve the issue.

Also to add to the more devices to the mix, the hotspot works equally as bad from my iPhone 12 Mini to Macbook Air (M1, Big Sur). I share my plan with a friend and his line (using iPhone 11 Pro) is experiencing the exact same issues as mine.

Same here - in fact I had to disconnect and reconnect three separate times just to read and post here. Stays connected for a couple minutes and then drops out. Have to forget it and shut off wifi on my laptop, and disable and enable the hot spot discoverability on my iPhone X. Very frusterating. Considering paying for the AT&T hotspot built into my truck but the service isn't as good so you can't win.

Same.  Hotspot on. Cellular signal drops constantly.

Same here. Got new iPhone 11 and new laptop and can't connect. Laptop doesn't sense the hotspot OR connects for a minute or so and then hotspot disappears and can't be found again. T-Mobile has to fix this!!!
