  1. My wife and I bought two Motorolla G7 cell phones at Walmart in Guaymas MX. And took them to the AT&T store next door and they unlocked the phone and put in an international chip, but unfortunately they gave us two phone numbers. One with a Guaymas prefix and the other with a Hermasillo prefix which we definitely want changed to a Guaymas prefix for both phones. We paid $120 US for each chip which they said under a promotion we were getting 5 months free on a 12 month contract.
    We are in the States and went into an AT&T store in San Diego because we were not getting emails unless we were connected to WIfi so we were showing there were days that we were getting emails but they were not showing up in our inbox. The AT&T representative told us that we needed to go back to AT&T and tell them that we were not getting data which is necessary to get our emails in real time. This is absolutely necessary as I get STOCK OPTION ALERTS through my subscription service and THE ALERTS are sent out in real time and I need to act on them as soon as I receive them and waiting until I can get a wifi connection is not acceptable and I need the DATA to be able to get an ALERT to make me aware when I receive a new ALERT in my inbox.
    Because I do not speak Spanish I think there is a communication barrier.
    We are coming back to Guaymas Mexico in a week and we would very much appreciate it if you would make your AT&T office or store in Guaymas aware of our problem so when we come in we can resolve these issues?
