How to Fix Signal Problems With Your LG V20

If you own an LG V20 smartphone you may have encountered a problem where your phone does not seem to have any signal, or has problems making proper calls, but you know you aren’t in a cellular dead spot. In this article, I will provide a brief tutorial on how to resolve issues with your LG V20 signal.

Issues Causing LG V20 Signal Error

There are three main reasons that you could encounter a problem with your LG V20 smartphone. The most common reason is that the radio inside the smartphone has been turned off. The radio sometimes switches off automatically if there are issues with your WiFi or GPS services. It’s also possible that you could have a problem with your IMEI number, or with the SIM card in your phone.

Resolving radio issues on your LG V20

  1. Go to the Dial pad
  2. Type in “*#*#4636#*#*”. NOTE: You don’t need to press the send button, your LG V20 should automatically give you the option to enter Service mode.
  3. Enter Service mode
  4. Select “Device information” or “Phone information”
  5. Select Run Ping test
  6. Click on the Turn Radio Off button and your LG V20 will restart
  7. Select reboot

Resolving IMEI issues on your LG V20

If you have a “No service” error on your LG V20, most of the time this occurs because of a nulled or unknown IEMI number. Fixing this issue is a little more complex, and you should read this article to fix this problem: Restore Null IMEI # and Fix Not Registered on Network

Resolving SIM card issues on your LG V20

The SIM card can also be an issue causing a signal problem. Check to see if the SIM card is inserted correctly, or replace the SIM card with another one, and this should resolve an issue with the SIM card.
