Does Huawei charge for continuous calls?

Huawei's continuous call is a service provided to users free of charge and will not charge users extra fees. This service aims to improve the call quality and stability. By applying the speech codec technology independently developed by Huawei, a clear and smooth call experience can still be guaranteed in the case of poor network signal or congestion. Users only need to use Huawei mobile phones that support this function and make sure to turn on the relevant settings, so they can enjoy this optimized calling service without paying extra fees.
