And since here (in this new thread) we have additional information about Taiwan Mobile as well and more explicit information to the effect that an ARC is required for a regular service contract (as opposed to prepaid service), i hope one of the moderators will combine these two threads into a sticky “read me first”.
Maybe “Cell Phone, 3G SIM, 3G internet FAQ (READ FIRST)”
PS: Do you think these threads could be added to the FAQ?
