Pros: I could see and feel everything around like never before. I felt calm and less tired.
Cons: I did not know the time, at the end of the second day I was not sure about the date, there were no public phones to call my family (I've been traveling alone). I did not know the route but I had finally learnt to actually orientate - which is really cool. I could not call the taxi. I could not log into my bank app. I could not even rent a bike during a walk 'cause you need the app, haha..
I can't say I regret not having my phone with me, but I do admit the phone is a cool thing to have!!
