What is VoLTE?

VoLTE stands for "Voice over LTE". This means your calls are made over the 4G network instead of the older 2G or 3G networks. It provides better coverage, clearer sound, and faster call setup.

What are the benefits?

• Improved coverage throughout the country

• Faster call connection times – especially in satellite areas (applies to local, national, and international calls)

• Better sound quality during calls

• Ability to make calls and use data at the same time

• Longer battery life on your mobile phone

Do I need to do anything?

No. In most cases, VoLTE is already activated. You just need a mobile phone that supports it.

Can I use VoLTE on my phone?

Most modern smartphones support VoLTE. You can check on your phone by going to Settings > Mobile networks > VoLTE. For more details, find instructions for iPhones and Android phones here:

Does it work abroad?

Yes – but only in countries where we have VoLTE roaming agreements. You can find a list of supported countries here

Do additional services like call forwarding still work?

Yes – but please note that changes made on the 4G (VoLTE) network don’t automatically apply to 2G/3G. If you switch between networks, you may need to adjust settings on both.

Does it cost anything to use VoLTE?

No. Using VoLTE doesn’t cost extra. It simply replaces the older 2G/3G calling technology.

Does VoLTE use my mobile data?

No – calls made over VoLTE do not use your mobile data allowance.

What if the sound quality is poor, even with VoLTE turned on?

Just like with 2G or 3G, you may experience poor signal in remote areas or in buildings with thick walls or basements. Call quality is also best when both parties have VoLTE enabled. If you experience ongoing issues, please contact Customer Service via our contact form or call 808080 (Private) or 808090 (Business).

Important information for customers with Huawei and OnePlus devices when traveling abroad

We would like to point out that customers with certain Huawei and OnePlus devices may experience restrictions when using voice calls while in selected countries.

In countries where the 2G network has been phased out and voice is only supported via VoLTE (Voice over LTE), affected customers may experience that they cannot make or receive calls.

What still works?
Mobile data will continue to work via our roaming agreements.

Who may be affected?
Customers with Huawei and OnePlus devices who are traveling to countries where voice is only provided via VoLTE.

Tusass is on the issue together with the relevant manufacturers to clarify possible solutions.
