Sorry, I should have updated this ASAP.
So what I figured out was that back then, Telus signals weren't up to date with signals. They have updated/graded their transmissions/send/receiving back in 2010 October-ish so that Korean txt coming from other providers can be read and sent.
So it's all smooth flying from here.
This is TELUS Provider in CANADA. So now I guess all providers in Canada can send/receive txts in Korean whether it'd be different providers or not.
