Network - continuously - doesn't stay connected

how long ago did that tower covering you go live with 5G?

and since you mentioned 4 of the other devices work fine minus yours..what phones do they have and which phone do you have?

all 5 phones having issues in the same area i would say network related..but since its only yours its going to boil down to either a problem with the sim card..how the phone itself is trying to read/use the 5G or something mucked up with your line only..

if its an iphone (been seeing a lot of network issues with them and 5G lately) you can try going into your mobile data settings and try changing to 4G instead and see if it stabilizes or not..
