You dont need a international text messaging plan to send international text. Text messages, sent or received, internationally:
Do not pull from text messaging plan
Charged at $0.20 per message
International charges do not apply to Canadian numbers.
To send enter 011 + country code + phone number
Are you looking for an international messaging plan similar to the international long-distance calling plan where there is a fixed monthly charge with reduced per-message rates by country? We'd be happy to pass your suggestion along to Marketing but need more information as to what exactly you're looking for.
