^ if u r always in the same cities you may want to look at WIND mobile or MOBILICITY;
they both have plans as low as 30$/month; mobilicity also includes unlimited tethering including calls to USA, intl SMS..
if u need a larger zone then WIND; no tethering though; and then we go to the legacy providers...(too expensive; not flex; etc. etc.)
EDIT:
here is the link for MOBILICITY;
