Hui 'an County, Quanzhou City, Fujian Province, I have a telecom "all-in-one", and there is no signal this year. Is it reasonable for telecom to upgrade to Tianyi on the grounds of base station maintenance? Because PHS is going to be delisted, the base stations are basically not powered for maintenance, and the final choice is still in your hands. You can use it or not. If your number is used for a long time, you can continue to use it. If you don't mind, you can change the number to something else, but personally, changing to Tianyi won't affect you, and the signal of Tianyi really doesn't make sense now. If you use it, it will be quick, because I use Tianyi.
