Answer: It works automatically and seamlessly. With our Africa Regional Plan, you don't need to change any settings when moving between the 29 covered countries (e.g., crossing from South Africa to Zimbabwe or Kenya to Tanzania).
How it works: Simply keep "Data Roaming" ON for your Cellesim line. Your phone will detect the border crossing and automatically connect to the new local partner network (like Vodacom, MTN, or Airtel) within minutes.
