Is my SouthESIM valid for Tanzania (Serengeti) if I cross from Kenya?

This specific SouthESIM plan is designed to work only within Kenya. Many travelers combine the breathtaking wildlife experiences of Kenya's Masai Mara with Tanzania's Serengeti for the Great Migration. If your journey takes you across the border at points like Namanga or Isebania, your Kenya-specific connection will cease. For an uninterrupted experience across both countries, consider one of SouthESIM's multi-country Africa bundles. They offer excellent value and continuous data as you explore.
