Hello. I’ve had my phone for 4 years now I think. A few days ago, it started dropping calls & the T-Mobile network would suddenly fade out. Then yesterday, unable to make calls at all. I’ve called & there’s nothing wrong with T-Mobile in my area. I’ve tried turning the phone off & on repeatedly, Taking the sim card out & putting it in the second sim card slot, taking out the battery for a bit then restarting. Nothing seems to budge the problem. Any ideas? I so hate to buy another phone. Thanks!
Welcome!
Sorry to hear that.
Can you share the first four of the serial, as well as what Android version you are currently using?
You can find this information in Settings
Hello, I was rather desperate to have a working phone so I ended up calling customer service. They think the phone has just gone bad & are sending a new one. Thank you anyways though!!
Ah, okay. Let us know how you get on!
Thank you!! It’s so amazing how dependent we get on our phones these days! I hope it arrives soon!

Since August 2026, I have suddenly had similar issues with T-Mobile and the Teracube 2e. The phone suddenly reports zero bars and no service–the mobile bars icon shows an exclamation mark.
I am using the latest /e/OS and had no issues previously. No changes. No updates (that I know of). The issue suddenly started around August 26, 2026. Note: this affects TWO seperate Teracube 2e units similarly so I am skeptical that this is a phone issue itself. Reports to T-Mobile suggest the Teracube 2e does not support Band 12 although the Teracube 2e specs seem to suggest the phone does support this band and no prior issues. This is frustrating as BOTH phones are now effectively dead when used at home (but seem to work in other areas). Anyone with any ideas?
If it helps, the first four of the serial numbers are 2021. The Android version is 16 (/e/OS 4.2-a16-20260815).
Do you know if they are changing the infrastructure in your region?
I have had ATT change the main band in my region, which resulted in me not having much service until I changed my SIM last week for a new one (I was still using my SIM from cingular wireless haha).
If your SIM is more than maybe 5 years old, perhaps try swapping that as well.
