How to ensure your phone is ready for the 3G switch off

[JonathanB]

We've phased out our 3G network in most areas around the UK.

Please check your settings are correctly enabled to be able to connect to our network.

Here’s how to check you have the right settings for 4G data and 4G Calling (VoLTE) connectivity;

1. Check for a software update:

Android: Settings > System > About phone > Updates > Check for update

iPhone (iOS): Settings > General > Software Update

Samsung: Settings > Software Update > Download & Install

2. Check you have 4G data enabled:

Android: Settings > Network & Connection > Mobile Networks > Preferred Network Type > Tap 4G

iPhone (iOS): Settings > Mobile data > Mobile data Options > Voice & Data > Tap 4G

Samsung: Settings> Connections > Mobile Networks > Network Mode > LTE/3G/2G

3. Check you have 4G Calling (VoLTE) enabled:

If you’ve bought your device from Three, we’ve got you covered and have auto enabled this setting already. So, you may not see the options to change this.

If you have bought your device from outside of the UK then we can not guarantee this option will be available.

To check follow these steps below

Android: Settings > Network & Internet > SIMs > Tap preferred SIM > Tap 4G Calling to ON to enable

iPhone (iOS): Settings > Mobile data > Mobile data Options > Voice & Data > Toggle VoLTE button to ON to enable (iOS)

Samsung: Settings> Connections > Mobile Networks > Toggle VoLTE button to ON to enable

• If using a dual SIM phone, check the Three SIM card is in SIM slot 1 and the Three SIM is selected as your primary SIM.
• Check if you have battery saver setting. If enabled, toggle off.
• Try turning off Wi-Fi while changing any device settings.
• If you need to reset your mobile network settings, this will revert all network settings to the original factory settings. Note this will include all Wi-Fi networks and passwords, cellular settings and VPN/APN settings that you have used before.
  
  

Settings may differ depending on your device and software type. Please refer to the device support tool for device-specific settings help. You can also find info in the specifications tab which will confirm whether your phone is compatible with VoLTE/4G calling on the Three UK network.

We aim to include as many device makes & models as possible, but if your device isn’t listed in our support pages, please reach out to your manufacturer for support. You can also find more info about our plans to switch off 3G here.
