O2 and Vodafone have issued information around this, which we are sharing to help customers be aware before they travel.
Our O2 network will continue to support all types of mobile devices in the UK. But if you are planning to travel to the USA, you will experience service issues. A phased 3G switch-off has begun and will continue into 2023.
Issues will impact all mobile network operators with roaming agreements within the USA.
O2 advise, if your customers are going to the USA, you should have the following to ensure the best levels of service:
· A 4G or 5G phone, which supports 4G Calling when roaming
· 4G or 5G enabled SIM
· A compatible tariff - 4G Calling enabled on subscription and device
As device manufacturers release new firmware updates from time to time, you should make sure your device has the most recent software version.
Vodafone’s network roaming partners in the USA (AT&T and T-Mobile) have switched off their 3G services. This means customers may have noticed an impact on their roaming experience, including voice calls.
Vodafone has worked hard to improve the roaming experience for customers travelling to the USA and can confirm that 4G Calling USA is now live.
4G Calling, also known as Voice over LTE or VoLTE, is a way of making phone calls over the 4G network, which should result in improved call quality.
To access 4G Calling abroad, customers will need to make sure their phone is updated to the latest software version.
Simon Gardner, sales manager for Lister Unified Communications, said: “Roaming has changed a lot in the last year, with charges brought in for roaming in the EU. But most people are not aware of changes to the US networks that will affect your ability to be able to use you mobile whilst roaming in the USA.”
If any further information or guidance is released to us by the networks, we will ensure this is passed on to our customers at the earliest opportunity.
If you have further questions on anything about roaming in the USA and 3G, please get in touch with your account manager at Listers.
