How the 3G switch-off may affect your service while you’re abroad

Network operators around the world are starting to switch off their 3G services. This is so they can free up capacity to expand their 4G coverage and add new 5G services.

If you travel to a country where 3G services have been switched off, your roaming experience might be impacted. This will depend on whether 4G Calling abroad is available in the country you’re visiting, and if your device is compatible.
