Voice over LTE (VoLTE) FAQs

What is Voice over LTE (VoLTE)

Voice over LTE lets you make clearer phone calls over our 4G (also known as LTE) network, where it's available

More importantly, when our 3G network closes in June 2024, you’ll need VoLTE to make or receive phone calls. We’ll share more information about the 3G network closure in later 2023.

What devices are compatible with VoLTE on Belong’s network?

To use VoLTE, you'll need a 4G/5G device which is VoLTE-capable. It will also need to be compatible with the following technology and bands:

  • Required: 4G 700 MHz (B28) banding

  • Optional: 4G 1800 MHz (B3) banding

We have listed some common devices based on our reporting support VoLTE below. Device manufacturers may update device firmware from time to time, which may impact the device’s ability to support VoLTE. Also, handsets purchased overseas may not be compatible. (Check back regularly as we will update this list as more devices become compatible.)

You sent me an SMS. What's this service issue all about?

From January to March this year, some customers had problems with:

  1. Making and receiving calls

  2. Sending SMS over wi-fi connections.

The issue has been fixed

These issues were likely caused by a software update in January that affected your phone’s ability to use VoLTE.
