You don't have to have a phone but then you have to register your round in advance faff around with a card, remember your pencil and generally waste time when you want a knock with your mates. There is no requirement to keep your handicap up to date and many people didn't before the WHS, they are not changing their habits now. And plenty who did no longer see the point as the system is seen as a fiddle, why bother with a cheats charter?You don't have to have a phone to do it the 'old fashioned' way.
Personally I enter competitions and have enough cards that general play cards are superfluous but I certainly don't want to waste my time and everyone else's by putting them in.
