Is VoLTE (Voice over LTE) supported by SumoSim?

Absolutely! SumoSim fully supports VoLTE (Voice over LTE)

VoLTE is a modern voice calling technology that enables high-definition calls over the 4G (LTE) network, rather than relying on older 2G or 3G connections.

Why VoLTE makes a difference:

• Exceptional call clarity – Enjoy crisp, HD-quality conversations.

• Faster call setup – Connect calls more quickly than with traditional networks.

• Seamless multitasking – Talk on the phone while using mobile data for apps or browsing.

• Improved indoor coverage – VoLTE often enhances signal strength inside buildings.

There’s nothing you need to do to activate it. If your phone supports VoLTE and you're in a compatible area, it will work automatically.

Not sure if your device is VoLTE-ready? You can check by going to your phone’s Settings > Mobile Networks > VoLTE, or simply reach out to SumoSim Support via our Online Chat ****
