Is my Mozambique WorldESIM valid if I cross the border from South Africa?

A WorldESIM plan specifically for Mozambique provides excellent coverage within its national borders. However, if your journey includes driving across the border from South Africa (e.g., via the Komatipoort crossing), your Mozambique-specific eSIM will not cover your time in South Africa, and your South African network will cease to function or incur high roaming fees upon entering Mozambique. For seamless connectivity across both nations, WorldESIM recommends purchasing a regional Africa eSIM or a global bundle that includes both South Africa and Mozambique.
