not gonna lie this is driving me nuts my office had weak signal so i used iPhones hidden Field Test.
dial 3001#12345# and press call. A diagnostic screen opens with cellular details. i looked for RSRP values while walking around, near the window it was much better than at my desk.
it doesnt change anything, its just information. the screen is very technical, but you only need teh signal number :) i moved my desk by teh window, and calls stopped dropping. pls help 🙏
