Here in Taipei there's more cafes than ever and most have free Wi-Fi, and of course accommodation always has free Wi-Fi too. So I don't bother spending money for Wi-Fi access.
There do seem to be a bunch of wireless internet that have Wi-Fi signals all over the place that you would buy a membership for and then access at any of their hotspots (CHT is the biggest). It seems that in convenience stores you typically pick up several of those signals.
Sometimes I wish I could quickly double check something on Google when my offline map isn't up to snuff. Looking for a hostel or Airbnb at short notice when arriving in a new town would be another use case. But the English is often poor or absent on the gateway pages that pop up when you connect to these signals, and connecting to each one in turn and trying to figure it out can chew through device batteries faster than normal use.
Might sometimes one of the signals actually be a free one provided by the convenience store chain, perhaps offering ten minutes free or similar, as I've experienced elsewhere?
Does anyone know if any of the many convenience store chains here have free Wi-Fi even for a short time?
