Is there a trick to text messaging friends overseas from my iPhone? I tried texting Mexico and it bounced. I know the phone number is valid.
You want to make sure you put + then the country code then area code when sending internationally.
Example: If you are in Mexico sending to US you would put +15553339999 (1 is US country code)
In fact, Mexico is 011 52 1 <area code> <number>, while Canada is still 1 <area code> <number>.
Hmmm. I think I tried that too. I'd give it another go.
I know that they list how to dial it in the front of your local phone book, so you may want to have a look at that, if you have one near you.
