The O2 network will continue to support all types of mobile devices in the UK, but if you’re planning to travel to the USA, some phones won’t be compatible with USA networks from 2023. This is because American mobile phone carriers are upgrading their networks and shutting down their 2G and 3G services. It impacts all mobile network operators with roaming agreements with networks in the USA.

So, if you’re going to the USA on business in 2023 or beyond and wish to use your phone, you’ll need to ensure you have the following:

  • A 4G or 5G phone, which supports 4G calling when roaming (see below) with the latest software installed
  • A 4G or 5G-enabled sim
  • 4G calling switched on, on your device. If you don’t think this is set up on the network please get in touch with your account manager.

You can make calls, send texts, and use data if you have all the above.

As device manufacturers release new firmware updates from time to time, please make sure you have the most recent version. Apple devices require iOS 15 or above. Manufacturers using the Android operating system may have enabled it on different versions.

Device compatibility may change from time to time. However, the following devices can currently make 4G calls when roaming.
