I have a samsung galaxy S3 with Salt prepay connection. The network at my school is quite unstable, so I hope to be able to use the wifi-calling option. Does anyone have an idea about how to configure the wifi-calling option? I did activate from "my account" in the webpage, but do not know what settings to make on my phone. The new website advertises a lot about wifi-calling but I cannot (or am blind
) find much info about how to use it. I read somewhere that they support only S5 and up, does that mean they are showing middle finger to old handset users?
