- Make sure your iOS device has an active cellular cnecti that allows it to access and use the field test mode to measure signal strength.
- Note that you will ly be able to check the power of 4G recepti the nearest cell tower. the iPhone with an Intel wireless modem. I'm sorry, you can ly get it the device with a Qualcomm modem.

- The devices which you can see the cellular cnecti in decibel-milliwatts are iPhone X: A1901, iPhone 8: A1905, iPhone 8 Plus: A1897, iPhone 7: A1778 and iPhone 7 Plus: A1784. Go to this post to check if the …
