I stayed in Hong Kong around twice per year for a few weeks. I typically pick up a prepaid mobile SIM+few calling minutes at the convenient stores. The next trip, this SIM always expired. I am never able to get an online account on these prepaid mobile SIM.
I am light call user. I pick up low cost GSM phone in Kowloon. I have tried PCCW, Peoples, Smartone,
What do you recommend I should do in my future trips?
Thank you.
