I've been in need of wifi calling. I was happy to see we was finally getting it. I have 2 Turbo 2's on my plan, and neither have received the update. I've tried using the computer with upgrade assistant also. Says we are up to date even though I see everyone talking they've had updated for several weeks.
Try to pull the update down while the SIM card is out of the phone.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
