You can download google maps for use offline, before you travel, negating the need for Wi Fi or internet when travelling. Also you can if you have a reasonably modern Android or iPhone 'hotspot' the phones 4G to your ipad & use your phones data. I often do this when travelling and need to answer emails & easier on ipad than phone.I am no better with a phone than with a sat nav unfortunately. I do have maps on my iPad but I prefer to be able to see a large area and I think I need internet to use the app.
To download maps so you can use offline.
