Went from 3 bars to 1 after upgrade
I upgraded to the Iphone 12 almost two years ago. Since then I had 3 bars in my house across all devices. Now as of September 2022 after “upgrades” to towers I now have 0 bars in my house across all devices. Turn phones off an on again, updating software does not work. I look at the online coverage map it says I should have 4G. I contacted customer support they said their was a service lock on my phones and transferred me to technical assistance. The person I talked to says they show no service in my area. This is unconscionable. How can my family go from 3 bars to none after T-mobile network upgrades to towers as of September? How can T-mobile show bright pink coverage for my address and yet no service according to your tech support? Is T-mobile forcing phone upgrades if they want signal. What has happened and what am I paying for?!!
