Then you can use maps stored on the device and get a modern camera and lots of storage and so on but you aren't constantly checking apps for notifications and whatever.
This is what I do. I use HERE WeGO for offline maps, check messages when there's wifi. Saves a lot of money too! Never experienced problems so far. I think it's easier when you never had a data plan, going 'back' might be tough as you've changed your habits to rely on a data plan.
