Why it worked

The video provides a practical, actionable tip for a common user frustration (poor signal) that is easily overlooked. The use of a 'hidden' menu adds an element of discovery, and the clear explanation of metrics with a visual demonstration makes the information accessible and valuable.

Summary

This video demonstrates a hidden menu on iPhones that allows users to check their true cellular signal strength using RSRP and SNR values. By dialing a specific code, users can access this data and identify areas with better signal reception within their homes.

Structure

5Demonstrate signal strength variation by moving around
6Conclude with a call to action

Product placement

iPhone: ACTS - it is operated to show signal strength. Removing it would change what happens in the video. Apple: APPEARS - it is the brand of the phone, a corner watermark. Removing it would not change what happens in the video.

Original caption

Your iPhone has a hidden menu that shows your real signal strength. Open the Phone app and dial: *3001#12345#* Then tap Call. Go to Serving Cell Measurements and look for these two numbers: RSRP (Signal Strength) • -80 to -90 dBm = Excellent • -91 to -100 dBm = Good • -101 to -110 dBm = Fair • -111 to -120 dBm = Poor • Below -120 dBm = Very Poor SNR (Signal Quality) • 20+ dB = Excellent • 13–20 dB = Good • 5–13 dB = Fair • 0–5 dB = Poor • Below 0 dB = Very Poor If your numbers are low, try moving closer to a window or a different room. Your iPhone’s signal bars don’t always tell the full story.
