手提電話公司，那個網絡收得最好

depends on where you normally stay, I think Peoples is pretty good in NT.
PCCW is the worst. 3 is not very good in reception, but its 3G service is good.
CSL / One2Free / New World are one company but NW only offers GSM.
Smartone is ok lar.

CSL (1010 / One2Free) 或者 Smartone Vodafone
會是你的最佳選擇

1010同數碼通我覺得唔錯。
