Basically the main reactions when people learn that I do not own a smart is : - how do you do without google map ? (hint : I draw a map beforehand) - what! you don't have Whatsapp (No I use SMS and I do not get group notifications every 5 minutes)
- You don't need to have any group notifications enabled to use WhatsApp. You don't even need to be in any groups. A quick message / photo / video call is still useful.
- Preparing maps beforehand only works if there are no changes on the way, you know all the places you want to go to, and you're familiar with the transport options and schedule.
Sure, you may not find those useful in your daily usage. Just keep in mind that your view on limitations and benefits of those solutions may be skewed.
Google maps.
That’s about it.
