I am very grateful that my wife have made few Korean friends to talk to here but I have just one small issue. Now that she is befriended with few people here she has started to use a lot of calls to cell phones. We got charged for about 500 minutes for couple of months now. That's about $1400 + Tax extra we are paying on top of our multiplan charges. I don't mind paying for extra but I am afraid of the consistent rise in minutes she uses each month and I am sure minutes will be rising higher as time pass and makes more friends. Is there better solution to paying less for calling her friends here?
