Gateway stopped working after two months

I’ve had my gateway for about 3 months to the day when mine just dropped out, even though I have 4 bars and shows connected to the internet but can’t get any data. Went out 12/6/23. I have exchanged my gateway 4 times with new SIM cards each time. Spent over 5-6 hours on the phone and had to go to the store 5 times. Done every thing you can do troubleshooting. They opened up several tickets for technicians to check the towers and they have come back saying they are fine. I’m not far from the tower and I’m in the center of a strong 5G area. Even on my cell phone I have trouble even running data. I was using my wife’s hot spot on her phone which is Verizon 4G LTE and can run video without any issues. So I turned my 5G off and turned on 4G LTE only and haven’t had any issues since on my phone. Gateway still not working!! I think it’s safe to say that tmobiles 5G is total garbage, that or their technicians aren’t doing their jobs. My wife works from home and had to use her Verizon hot spot to work for the last 8 working days. Liked the $30 a month internet, but I talked to spectrum and got 500 megabytes per second for $29.99 a month for 2 years. Might have to figure out a way to get out of T-Mobile and go to Verizon. Only time will tell. Good luck anyone having issues like this.
