When we first flew into Portugal, Bri had his cellphone service. He paid $10 a day to use it there. However, the GPS wasn't working when we started to drive to our hotel in Lisbon. I was panicking since I could not read a map on how to get there. Brian eventually stopped the car and downloaded the Lisbon map so we didn't have to use data.
Turns out, roaming data is turned off by default on phones now. We finally figured out how to turn it on so Bri could use his data so we can get to where we were going.
