Today, many new phones are able to utilize the Voice over LTE (VoLTE) signal to transmit calls more clearly and over stronger data signals. However, there may be times that this option is either unavailable in your area, the LTE signal in your area is weak or unavailable, or your phone does not have the ability to either utilize the VoLTE option or receive calls from someone utilizing this feature. When this happens, we have found that some people cannot place a phone call. There may be a way to get around this issue if VoLTE does not work.
Apple Support came out with an article recently, educating customers on the use of VoLTE with an iPhone. You can view that article here: https://support.apple.com/en-us/HT203078.
Here are the steps with an iPhone 6 or newer:
- Go into your iPhone "Settings" app
- Go into "Cellular" (should be the fourth option from the top)
- Go into "Cellular Data Options" (should be the second option from the top)
- Go into "Enable LTE" (top option)
- Switch the LTE to "Data Only"
- Go back to your home screen and toggle Airplane Mode on and off - this resets your phone to the new settings
- Now attempt to make a call. You should now have a fully-functioning phone!
Found through Verizon's website, there was an FAQ section about turning HD Voice (VoLTE) off on Android devices.
Here are the steps for Android devices:
- Go to "Settings"
- Tap "Advanced Calling" under "WIRELESS NETWORKS"
- Tap "Advanced Calling" again to turn it Off
If you have an older device like Samsung Galaxy S5 or Motorola Droid Ultra/Maxx/Mini, follow these steps to turn HD Voice off:
- Go to "Settings"
- Tap "More Networks" or "Tethering & Networks"
- Tap "Mobile Networks"
- Tap the "VoLTE Call" setting to turn it to Off
- You can access this setting after you've added the HD voice feature to your account
- "If VoLTE Call" is set to Off, then HD Voice is disabled
There are only currently only certain phones and carriers that will allow for calls to be transmitted over the 4G/LTE signal.
