I am getting AIO even thought AIO was not able to port my AT&T number. It really didn't matter that I get a new number since I like to refresh my number every few years to get rid of all the dead connections anyway. but the point is, Not every AT&T can be transferred. I called AIO to report the problem, then I conference call to AT&T, let those two talk but none of them knew what to do.
AIO customer service is very nice in terms of friendly and kind but, they are not able to resolve any technical issues as they are only following the script.
For instance, with my porting problem, AIO customer service could only try it the EXACTLY same way that I tried the first time. type my information AIO website and see if they have a better luck... they have no way to tell you what's wrong nor any authority to fix anything if anything goes wrong, like ordering the wrong thing.
so even if AIO rep does something wrong, they no way to fix it, and you have to deal with it on your end.
Even though they are very nice, it's frustrating to hear "There's nothing we can do " with smiley face in the end. They must be told to put at the end of every sentence by their trainers.
so if you are absolutely sure to go with AIO, then do it. I did. It's the same AT&T network and owned by AT&T. Even AT&T rep told me I should go with AIO for better pricing.
but if anything goes wrong technically like if you can't activate or number can't be ported or any other issues, AIO has NO WAY to fix it for you. I mean, NO WAY.
hope this helped.
