Is kc VoIP traffic used to send text messages?

Hello, landlord. The mobile phone you mentioned can't send text messages at present. It uses the Internet as the medium of voice transmission, thus realizing voice communication. Like you, I'm beginning to have this idea. There's nothing to lose by trying, so I'll use it. If you want to make a phone call, it's good to use this

Save it, because as long as you have traffic and the network is smooth, you can make calls with traffic.
