How about giving the user option to use VOLTE without being supported by the provider? I can understand that it takes a lot of time and money to support VOLTE for a provider, but if you are not willing to spend the time and/or the money then please allow us to use it but without support. saying that if there is a problem we cannot fix it since you don't have support. Exactly like the custom roms provide it....I doubt there will be legal issues with this since all the custom roms use it....If not, please speed up the VOLTE support for the markets where you are selling the phone...It's been more than 6 months since I bought the phone in Germany and there is no work about VOLTE support for Vodafone DE.
