Charles33579, first and foremost, I personally apologize that you've been on the line with our Technical Support team for 30 minutes and haven't received an answer to your inquiry about the Wi-Fi Calling feature failing to activate on your prepaid device. We know how extremely busy many of our customers are and we truly value your time. Wi-Fi Calling is a great convenience for our customers and many HD Voice-capable devices also support Wi-Fi Calling for both postpay and prepaid devices we offer. You can view additional information about Wi-Fi Calling including how to enable this feature for your device at https://www.verizonwireless.com/support/wifi-calling-faqs/?cmp=COMM_RELCON. I hope this is helpful. - RobertC_VZW
