Telcel is the dominant cell phone carrier in México. Google AppEngine uses a SMS to confirm the registration process but Telcel it’s not supported (I can figure out why, since Telcel is not known for it’s openess). So that leaved us trying to get some friend with a Telefónica phone to use it to register on AppEngine… until today. I filled the form to report a failure on the SMS service and got a reply from Google saying that they have activated my account. Cool and fast!
