After a day on Verizon I'm finding myself wondering why I didn't do this quite awhile back. Call quality in my area is much better on Verizon than it is on T-Mobile, and the data service is miles better. TMo is 2G here, Verizon and AT&T are 4G/LTE. Sprint is 3G. After talking to some friends that have different services around here, the bottom line is that if you want the best coverage for voice/text, it is Verizon and Alltel and data is better on Verizon since Alltel is EDVO(?).
With my calling patterns and useage, the Senior Plans that both Verizon and AT&T have are fine with me. Those I talked to that had AT&T said that the service with them was a bit spotty and more narrowly around the major highways where Verizon is really strong nearly everywhere. I live in the boonies so that is a concern.
I was very surprised at the FaceTime performance. I played around with it and tried my daughter. I didn't even know she had an iPhone as the subject never came up. I called and she answered and the quality was great on the picture and sound. I tried it both with wifi and using the 4G/LTE and the difference wasn't much at all and I'm on 6M/.5M DSL service! A question. If I'm on wifi at home and call via Facetime, does it use my cell for the voice and wifi for data or wifi for both??
