Do a iPhone signal quality test! The bars that your iPhone displays are guesstimates of your true signal quality. To find the true quality of your signal go into the phone app and press *3001#12345#* and call. Look at the top left corner (where the bars are) and you will see some numbers. This is your -db number and is indicative of your signal strength. Its a negative number so lower is better. Anything below 75 is legit. 85-75 is average. 95 is getting kinda meh. 110+ is wtf. Mines about 100+ where i live and i get about 85 else where. What yours?
