Cell Phone Signal Strength

This post is only for technology-curious people who have an iPhone.  Android users can find the information somewhere in their phone's Settings.

When you dial *3001#12345#* (including all the special characters), you can find some information about your connection to the cellular network.  The carrier listed below is TFW, which is short for TracFone Wireless, which Verizon bought and is now the label for Total Wireless.  The signal strength is the RSRP (Reference Signal Received Power) and RSRQ (Reference Signal Received Quality) numbers.  Since the phone has one bar, you would expect some bad numbers, and they are.  An RSRP between 0 and -90 dBm is considered good and the -127 dBm shown here is solidly in the bad range.  The RSRQ of -29 dBm is also really bad.

Lots more information for the curious can be found at the link below.
