What Does “O2 Has Turned Off 4G Calls on Your Account” Mean

“O2 has turned off 4G calls on your account” is a message that some O2 users may encounter. It suggests that the Voice over Long-Term Evolution (VoLTE) or 4G calling capability on your account has been deactivated for some reason.

4G calls, or VoLTE, is a network feature that allows voice calls to be carried over 4G networks, which leads to improved audio quality during calls, better coverage, and faster call set-up times.

If this feature is deactivated, your phone will default to 3G or 2G networks for voice calls, which may result in a noticeable drop in call quality.

Here are some potential causes that may have caused this notification to pop up on your phone:

1. Your Phone Had a Data Update

It is possible that there has been a data update on your phone recently.

This data update could have been manual or automatic.

Devices often turn off VoLTE/4G/WiFi calling on their own when there has been a data update, which may have caused it to be turned off for your account.

As such, this may be the reason why you are getting that error message.

2. Changes in the O2 Network

O2 often carries out maintenance, whether it be online or offline, to improve their network and thus provide a better experience for its customers.

It is possible that they were carrying out such maintenance on the network that your O2 account is a part of.

During these maintenance processes, some features of your O2 connection might become unavailable for use –– one such being VoLTE/4G/WiFi calling.

This might have led to you receiving that notification on your phone.

3. Technical Issues with O2 or Your Device

There might be a technical issue behind the notification, be it a glitch or bug with the O2 network or your device itself.

These errors are often temporary and will not have any permanent effect on your network or your phone.
