How Do I Check My Phone’s Signal Strength? Cell phone signal boosters can help those with below-average signal. At -120 dBm or lower, your phone is just a paperweight. Calls drop, texts take long to send, videos constantly buffer, and webpages are slow. Around -100 dBm is where most experience inconsistent service and weak reception. You’ll be able to enjoy uninterrupted calls and fast data speeds. The closer you are to -50 dBm, the better your signal strength.

Decibel-milliwatts, or dBm for short, measures the strength of the wave. For Commercial Decibel-Milliwatts: The Most Accurate Cell Phone Signal Strength MeasurementĬell phone signals are radio waves (AM/FM) operating within certain cellular frequencies.
