Pete,
How long have you had that burner phone?
When the phones get outdated they are unsupported in all sorts of ways.
The memory gets faults just by aging. The battery uncharged? Or too old?
Murphy’s law your car breaks down in a place with no reception. You hoof it.
After some checking, it appears to be about 3 or 4 years old. Based on the model number, it is supposed to use 4G (LTE) technology.
As I wrote in the previous post, I charge it up every few weeks, after making sure it starts up properly and I can still make calls. I can also send a text to the carrier, and they text back with my remaining minutes and end date for the pre-paid plan.
I’ll probably buy a new one in a few years, but I think I will need to buy a new desktop computer first.
