there is an exploit that least gives you a chance at nailing the local first, but it's far from reliable... anyway, what you do is make sure you're capped before the 1st and have the router keep the session alive.. come new month don't reset the router, then local will be used firsthey guys...I know this has been asked 3 billion times on this forum, but can you access the local cap before abusing the international data at all? I can't afford my uncapped anymore and my parents have 8gb Telkom.
you see diane, you have to modify the hosts. file (see the link Pada gave) to force google stuff to run on local. uhm, how old is your son? kids are pretty tech savy these days, maybe he could help?
