Can an ATT Customer Keep a US Number While in Mexico (or Canada)?
I am a US resident AT&T customer with Unlimited Extra as wireless plan. I am considering snowbirding (or more) to Mexico.
One of the features of my plan is, "Enjoy unlimited talk, text, and data use in Mexico and Canada...." There are restrictions on data speeds, etc. For the context of my question, however, I am mostly concerned with talk. I want to keep my number with AT&T so that relatives can reach me easily, I can call the bank, I can stay in contact at work, etc. In short, I want to keep the US number and not have to deal with porting to an MVNO etc. I am very happy with AT&T. I will have a local number and data plan for daily use. I am not calling other foreign countries.
At one point, carriers placed a limit on roaming in Canada and Mexico as a percentage of total usage. However, when I look at the customer agreement for my Unlimited plan, it states that the plan covers use in AT&T's "North American Coverage Area," and the area in Mexico where I will be is within that area. I can view it on AT&T's coverage map. Some plan features are restricted to AT&T's "Domestic Coverage Area" which is basically the US, but, again, I have "unlimited talk, text, and data," in Canada and Mexico and I will be within the "North American Coverage Area." (Not all of Canada or Mexico is within that area.) I know AT&T has a presence in Mexico, if that makes a difference.
Does this mean that I can keep my number indefinitely or will I one day get cut off?
