Texting a South Korea Cell Phone Number
Can anyone tell me how to text a South Korea cell phone number? I am in the USA and using an AT&T phone. Tried various methods and all result in error messages. From the internet, it looked like I needed to enter +01182xxxxxxxxxxx. I also tried +82xxxxxxxxxxx. Neither way worked.... Thoughts?
Also, any info on texting rates from USA cell to South Korea cell phone number is appreciated.
