So, every upgrade, we all seem to get the same problem... getting wifi calling sorted.
I decided today to have a go so...
Call to vodafone...
"Hi, Can you send me a provisioning message please.
Its activated on my account but phone won't show option unless YOU send me a provisioning message"
"Yes sir, text CALLING to..."
Nope, that doesn't work!
Line goes dead.
Called back, same convo with another guy... "New phone - settings probably aren't available."
Please send me S22 Ultra settings, same basic phone running same O/S...
"Done"
Me - "Yessssss! It's working, thank you"
So if you have wifi calling issues, just tell them to send provisioning settings for S22 Ultra 👍👍
