That also doesn't make sense because up until recently my sms were sending just fine to the exact same number. The format hasn't suddenly changed.
My SMS messages are also not getting through from the UK to Thailand even though they say they have been delivered. A lousy service. The frustrating part is NOT knowing whether they have been delivered or not.
ME too!! USA to India! I did google and read some network/government junk there?! Not sure if that is why? Cant BBM. email, even a phone call.. very frustrated
