VoLTE and VoWIFI

Your usual calls, now with
top-quality sound and at no extra cost

We’ve enabled VoLTE and VoWiFi. Enjoy clearer call quality and stay connected even in areas with no mobile coverage – all natively from your smartphone.

What is VoLTE?

VoLTE (Voice over LTE) is an advanced technology that allows users to make and receive standard voice calls directly over the 4G data network, rather than via traditional 2G or 3G networks.

The revolution:

Instead of forcing the mobile phone to switch to older networks, VoLTE digitises the voice and sends it as high-speed data packets over the 4G network. This allows you to talk and browse the internet at the same time, at top speed.

What is VoWiFi?

VoWiFi (Voice over Wi-Fi) es la tecnología que permite realizar y recibir llamadas de voz tradicionales utilizando una conexión Wi-Fi, en lugar de la red móvil.

The revolution:

The phone uses the Wi-Fi network you’re connected to as if it were its own mobile signal. The call is routed seamlessly, allowing you to talk as normal indoors where there’s no mobile coverage.

What are the benefits?

Exclusive Benefits of VoLTE

  • High-Definition (HD) voice quality: Your calls sound much clearer, crisper and more natural, completely eliminating the annoying tinny sound typical of older networks.
  • Almost instant connection: No more waiting. When you make a call, the dial tone starts ringing in less than a second.
  • Browse at top speed whilst you talk: Talking and using the internet no longer gets interrupted or slowed down; you can continue to use your 4G/5G data seamlessly during an ongoing call.
  • Better battery life: As your mobile no longer needs to constantly switch between 4G, 3G and 2G networks to complete a call, the device’s energy consumption is significantly reduced.

Common benefits of both services

  • No apps or complicated settings: They work natively on your smartphone using your usual calling app, with no need to install anything else.
  • Más estabilidad en tu línea: Al utilizar las tecnologías de voz más modernas, tus conversaciones sufren menos caídas o fallos inesperados.
  • Completely free: Both services are included at no extra cost in all our tariffs, both current and discontinued.

Exclusive Benefits of VoWiFi

  • Calls where there used to be no signal: Stay connected from basements, garages or buildings with very limited mobile coverage, provided you have a Wi-Fi network available.
  • Smart, automatic handover: If you start a call over Wi-Fi indoors and then step outside, your device will automatically and seamlessly switch the call to the 4G network, without any interruption.
  • No mobile signal? No problem: If, for any reason, you don’t have a mobile signal on your phone but are connected to Wi-Fi within the UK, you’ll still be able to make and receive calls as normal.

FAQ

Frequently asked questions

Getting started is easier than it looks.

Do I need to change my SIM card or switch to an eSIM?

No, not at all. The SIM and eSIM cards you currently have in use are 100% compatible, so they do not need to be replaced.

No. Both services are included free of charge in all our plans, both current and discontinued. You will only be charged for standard usage, such as international calls or special roaming charges, that are not covered by your current plan.

Yes, that’s one of its key advantages. With VoLTE, voice calls are transmitted as data over the 4G network, allowing both voice and data to be used simultaneously at top speed, and with VoWiFi, both voice calls and data traffic travel simultaneously over the same Wi-Fi network.

The VoLTE mobile calling service will be available abroad provided that the operator in the country you are visiting offers this service on its network. For legal and regulatory reasons, the VoWiFi service is restricted and can only be used within the UK.
