This would be my recommendation after trying living without phone for a whole year once. Living without a phone is difficult, not worth the effort. You may not want to call anyone but people will want to contact you when you go out. However, it was really good for productivity. Recover so much time lost. You can try to live without a smart phone. There still some phones available without all the smart things and just voice calls. It is good to have it, at least to turn it on in case of an emergency.
