I bought a phone that is software upgradeable. The company that makes it has continuously make improvements, from 2G, 3G through 4G generations. I can use the phone to communicate anywhere on the 2G, 3G and 4G networks.
Last week, the company who makes the phone released firmware version 2.0 saying that this is the future and the phone would be able to run 5G. Apparently, the phone only works with 5G. If you go to areas that don’t have 5G coverage your phone won’t work at all.
This Sunday morning, I am driving in the woods just outside my neighbourhood, an area that don’t have a 5G signal and my car breaks down. I need to contact someone for help. I see clearly on my phone screen that 4G, 3G and 2G signals are available and very strong. But, still I cannot make a call and or even text a message to anybody because my phone now only works on 5G.
