My cell phone strength is one bar inside but 3 and 4 in the back yard. We are looking at booster amps but I don’t know what bands my phone uses. The importance of this is uncertain to me, but the ads for some of the amplifiers list the bands that the device supports.
Some searches say to dial *3001#12345#* to get those numbers. My phone does not look like any of the examples provided. Searching through what is displayed does not yield any of the expected fields.
This phone is model 11 and the iOS is 17.1.1
Here is the display obtained from that number.
What can be done to determine the bands used? What is the probability that just picking one of the amplifiers will work out well?
