You simply need to call the number 3001#12345#, and it will put your phone in “Field Test Mode.” Admittedly, the iPhone system sometimes fails to give accurate readings. Android phones are better at measuring signals, so you are better off borrowing one of those to make the test and decide if you get a signal booster or not.
