It looks good for spreading BTC around the World, don't think about your own countries guys! We will use QR Codes, NFC and others will use SMS;BTC is going to win at the end I hope...
SMS tends to be more expensive when sending internationally (and generally free domestically). I would argue that SMS payments would be better for sending money domestically.
If bitcoin is going to be a mainstream way to send money internationally then the "internet" is almost certainly going to be used to provide bitcoin addresses to send money to by the receiver.
I guess the sms would be sent only locally to the sms provider, even if the money is going to be sent internationally. The service provider would of course use the internet to move the coins.
Sending international sms'es to move bitcoins would be a deal breaker. Nobody would use it because of the prohibitive costs involved.
