Yes, significantly. Most US/UK/EU carriers (like AT&T, Verizon, Vodafone UK) charge expensive "Day Passes" ($10-$14 per day) for South Africa. A prepaid Cellesim eSIM is a one-time fee that gives you a large data bundle for a fraction of the cost. For the price of 2-3 "Day Passes," you can get data for your entire 2-week trip.
