Buying a Nighthawk M5 outright to replace my Nighthawk M1 WITHOUT changing or adding a plan.
My question is that if I purchase an M5 outright, put my sim card from my M1 into it, would it be able to access 5G on my current plan. I will not be changing my plan, or adding a new plan. The main reason I have the one that I do is because of the unlimited on the hotspot that is currently on it. This is the only option where I live for internet and we use 600-1000 GB/mo
We are grandfathered in to the Unlimited Plus plan with a 4g lte modem on the plan. Our phones are now connecting 5g where we live. If I purchase an M5 outright from say...Amazon, will it also start connecting 5G. I do not intend to change my plan, and I do not intend to add ANY kind of plan to be able to use the new M5. It simply wouldn't be worth it to me. I still get 100-200 Mbps now, but it's sometimes a little buggy. My phone can get 300+ Mbps and seems a bit more stable.
The M1 currently has a 5G nano sim card in it because I needed a new sim some time ago.
I could get an M5 and experiment with the intention of returning it if it didn't work, but I also have this thought lurking in the back of my mind. A few years ago, a friend of mine had multiple phones with unlimited on his account. He took the sim out of one and put it into a mobile hotspot. Then he got some ridiculous bill from AT&T once the system detected that it was a hotspot and not a phone. I'm concerned that they will somehow change my plan without my consent if it detects the different modem.
