Review on 📶 Maximize Your Cell Phone Signal Boosting With SureCall's Five-Band RF Signal Meter (SC-METER-01) by Jeremy Carpenter

I live in the area and go to areas with very poor line and reception. I also have an iPhone for which Apple has largely disabled diagnostic information such as LTE-Verizon. Signal level in dBm SMH! So this is the next best thing after buying an Android and running it in "Field Test Mode (with valid SIM)". For me, my maximum signal level was -49 dBm. but for some reason the weakest signal is shown as "-70dBm" which as we all know is not the weakest signal reading (should be closer to -120). So, I believe this is a counter error - let me rephrase, The only readable range on the meter was -49dBm to -70dBm. No matter which way I point my Yagi directional antenna - IMHO it should read "low" or a number down to -120dBm and then low which would make more sense. But again, if you have an iPhone like me, we're stuck.
