Our current phone strategy is a rather untraditional phone set up, but it works pretty well for what we need. We are all wifi. We don’t really have a phone plane. We have options for wifi.
Most everywhere has wifi. Hotels, airports, restaurants, most stores, the walking mall in Cville, the busses and parks in Hong Kong, etc… You’re close to wifi at any given point in time.
More and more places have wifi and signals on phones and routers are getting better.
