WHAT IS VOLTE?

With VoLTE (Voice over LTE) you are making calls via the 4G network (LTE network) and thus using the latest telecommunications standard and the strongest connection. For your telephone calls this means crystal clear sound quality and an especially fast call connection.

FAST CONNECTION

Connection established immediately: calls with Voice over LTE ensure a much faster connection than with 2G or 3G.

OPTIMAL SOUND QUALITY

Make calls with excellent HD voice quality – especially if the person you’re talking to is also using VoLTE.

LOWER BATTERY USE

Without VoLTE, your mobile phone switches from 4G to 2G/3G and uses electricity to do so. With Voice over LTE this switch does not take place and your battery lasts longer.

FAQS

What does it cost to use VoLTE?

Calls via Voice over LTE will be billed as normal calls according to your UPC Mobile subscription and listed as usual in your UPC bill (without special labelling).

Why doesn’t VoLTE work for me?

There are various possible reasons for this:

No 4G network available
Please check whether a 4G network is available where you are. Only then is it possible to use Voice over LTE.


VoLTE is not activated.
If you have not yet activated VoLTE, simply open the Mobile Assistant and follow the step-by-step instructions.

Smartphone is not VoLTE compatible
If your mobile phone is not VoLTE compatible, you will not be able to use VoLTE. Check in the Mobile Assistant whether your smartphone model is listed for VoLTE.

You are abroad.
You can only use Voice over LTE within Switzerland.

Call I use VoLTE abroad?

No, Voice over LTE is only available within Switzerland.

What is the difference between VoLTE and Wifi Calling?

The difference is that calls with Voice over LTE take place via the 4G mobile network, and calls with Wifi Calling take place via a wifi connection. Both technologies are options that offer you even better call quality.

Wifi Calling can be convenient if you are in a place with weak mobile coverage, for example. When Wifi Calling is activated, you can simply make calls via your wifi connection in this case.

Can I deactivate VoLTE?

Yes, if you have activated VoLTE, you can deactivate it again in the same way.

Please note: If you deactivate VoLTE, you will miss out on the advantages such as excellent HD voice quality.
