There are still a number of countries not supporting instaboost. I would not recommend calling long distance to another country to try to instaboost though. Your call to another country to get rerouted to instaboost will cost you way more than the instabooster will. Best solution is to either buy one of the montly boosters via another method, or wait until instaboosting is supported in more areas.
