Yes. You go to airplane mode first to turn off all data/roaming/calling capability, then manually go to turn wifi back on so you can tap into that.To avoid nasty international roaming charges, If I want to access the free wi-fi in the Western Caribbean ports, should my phone be on airplane mode? Will that alone get me out of the call charges?
In Grand Cayman, there is a candy store right near the pier that has OPEN wifi, no code needed. They do have funky flavored gummy bears, which my husband and son bought tons of, while I taunted my co-workers with pictures on Facebook. In Costa Maya, we could not find any free wifi.
