For the past 5 days I have been reviewing the upcoming MR6150 12.01.29.00 firmware (not sure if this is final or beta) With T mobile service The MR6150 never connect to 5G service in fact it keep falling into LTE and speed barely reach 100. This happens in 3 different cities and states.basically it becomes an overprice MR 1100.
Current firmware 10.04.22.00 it will connect to 5g service and the speed range between 300-500 with the same sim card from T-mobile. again this is tested in 3 different cities and states. It does have quirk the modem wont stay on over 2 days. it will either turn off or rebooting. So make sure you have battery inside.
.
So if you like the speed AVOID the update until they fix it, cause you have no recourse to downgrade . But if you want stability BUY MR1100 instead which is known for stability and affordability 🙂
