I have the Pixel 2 and I just found out at&t doesn't support advance messaging because it's not a phone from at&t. Are there any plans to change this? Because if not I'm 100% leaving at&t. I'm studying abroad in a few months and Google Fi works abroad so I will just keep that afterwards.

Can I add HD Voice capability to an iPhone  5 by getting a new SIM card for it?When the iPhone 5 was first announced by Apple it noted that the iPhone 5 was HD Voice capable.  The problem was that AT&T did not have HD Voice at that time. I want to make my iPhone 5 HD Voice capable so I can use AT&T

Hello, My name is Dan I recently had some issues with my Samsung Galaxy S5 Active, and AT&T sent me a manufacturers refurbished phone.   Several months after having this refurbished phone is the data is extremely slow, and my coverage map is full of LTE and good HD voice and regular voice coverage.

I have owned my AT&T S7 Edge (6.0.1, Build MMB29M.G935AUCS4API2) for many months now, and love the phone. It is better than my previous Samsung AT&T phones in all aspects: Captivate S, S3, S5.
