I have a HK mobile phone number (New World Mobility) and I want to keep this number for too many people have this number.

My number will expire in mid November 2011 because I haven't had a chance to get back to HK.

I purchased a recharge coupon prior to leaving HK but stupid me, didn't think this through. To charge the telephone number I have to USE the phone in Hong Kong to recharge... or is there another way?

Is there a phone number I can call from overseas to tell them what my mobile phone number is and what the recharge coupon password is?

Thanks
