I have a Samsung S10 and I am having issues receiving SMS vis WiFi. I have very bad reception where we live, but was thrilled to receive today my first WiFi call. I had no idea we could use that feature on VM. I am now able to place and receive calls over WiFi.
However, I tried sending and receiving SMS which only worked partially. Tried sending an SMS, and worked like a charm. Tried replying form the other device, and message was sent, but never received.
I've read like 50 different blogs about WiFi text messaging and haven't been able to find a solution.
