I went back and looked at yesterday's posts. I couldn't find anything related to the number of customers already signed up in Mexico. I didn't read every post (looked at the first few words to see if somewhat relevant), so could have missed it.
At this early stage, even without the Uli issues, I would expect the number to be small, if any at all.
While looking, found this copy of a post from modlam that was at least an interesting read:
