How To Check Your Phone’s Signal Strength

Do you often find yourself struggling to get a good signal despite having bars? This is an inaccurate reading of your phone’s strength. The accurate way of reading your phone’s signal is by checking the decibel-milliwatts (dBm) reading. Begin discovering how to check your phone’s signal strength to understand why you’re dropping calls.

How To Check Signal Strength

Checking signal strength differs from phone to phone, and sometimes you can download apps to do the job for you.

Checking Your Signal on an iPhone

If you’re an iPhone user, checking your signal is a bit tricky. However, if you have an iPhone with an Intel chipset, you check your signal this by:

  • Dialing *3001#12345#* then pressing call

  • Tapping “LTW or Menu”

  • Tapping “Serving Cell Meas”

  • Finding “rsrp0”

“Rsrp0” is representative of your phone's signal strength. Once you've done this, close out of the tabs. Note that running a field test differs depending on the chipset and model.

Checking Your Signal On an Android

Running a field test on an Android is typically the same for all models. Do this by:

  • Going into “Settings”

  • Selecting “About Phone”

  • Tapping “Status or Network”

  • Tapping “SIM Status”

Once you’ve clicked into “SIM Status,” you’ll find your dBm reading.
