Our client has asked us to create an ExactTarget Landing page which captures international phone numbers into a data extension for possible later use in SMS messaging. This leaves me with a few questions.
First, is my understanding right that I cannot use ET's Phone Data Type because that is limited to 11 characters?
Second, should the number be formatted as if you are calling from within the non-US country or from the US. For example, in Argentina, the country code is 54 and to call a Buenos Aires number from the US, would look like this: +54 9 11 1234 5678.
However, to call a cell phone from within Argentina, one needs to add a 15 like this (11) 15 1234-5678 where 11 is the area code and 15 indicates it is a mobile number. If I am sending an SMS message from ET, does it already know the country code because of the short or long code I am using and should I then add the 15 (which is required
Third, should I use a number format or text format to get proper importing into ET's SMS Subscriber list. Does ET care whether I use (123) 123-1234 or 1231231234?
