and sending and receiving texts internationally? can anyone do that and on what service? i have personal and can't..
It's possible, but without an international plan (pack) it can eat up your credit quickly...
To send an internation text, just enter the number with country code and prefixed with a "+" plus sign. For the US:
+1 555 555 1234
To receive from abroad, the sender has to do the same thing, but should add a "9" before the argentinian city code:
+54 9 11 5555 1234
(note: no "15" cell phone code is needed).
To get the "+" sign on your cell phone, it depends on the phone you have, but for motorola you usually have to hold the "0" key for a second or so, and it will output the + sign.
You can store your numbers in that full format as well in your phone as it works also for making phone calls (locally or international). Its the best format to save your numbers if you travel with your cell or call international regularly.
