I've had this phone for 3 days and I love it but it's not working properly. I need wifi calling as I have no cell coverage in my home, and I have successfully used wifi with other phones in the past. I can make outgoing calls on wifi fine, and I can use wifi to browse and surf the internet. However, if someone calls me when when I am on wifi the phone doesn't ring, I don't get a "missed call" notification, and the call doesn't show up in my call log. I have tried calling the phone myself, and most of the time my call just goes straight to voice mail, although sometimes it rings 4 times before voice mail picks up. Regardless the phone itself shows no sign of any incoming call until a voice mail message is left.
I took the phone to the T-mobile store the day after I got it and they tested it on their wifi network and told me, yes, I am right, the phone doesn't ring for an incoming wifi call. They tried my sim in other phones in the store, and it worked fine with wifi. However, I don't think they tried my sim with another Blaze. Regardless, the rep at the T-mobile store told me he thought my phone was defective and I should return it. I packed the phone up to return it, but decided to call tech support first.
After multiple troubleshooting steps with a first level tech, I was put through to a second level tech who told me that he doesn't think it's a defective phone, but a network problem. Hmm, everybody else in my home can use wifi and I can use wifi on my old phone if I take the sim out of the Blaze and replace it in the old phone. The second tier tech tried everything he could think of including not one but two factory restores. The phone positively will not ring if it is on wifi calling.
Ultimately the tech put though a ticket, whatever that means, and told me he would follow up with me within 3 days with a resolution. In the meantime, I have another week or so to return the phone and buy another, or I can wait and try to get it replaced under warranty if it turns out to be a phone problem.
I see people with the HTC 1 having a similar problem. Does anybody with the Blaze have this problem as well? And if so, does anybody have a solution? I really like this phone, but I really need wifi calling to work, it's why I stick with T-mobile.
