Yes, your eSIM On Trip will generally provide coverage at the main lodges and dive centers on Mafia and Pemba Islands. While the signal might be a bit weaker compared to the main island of Unguja, you'll still be able to connect. Keep in mind, deep underwater, you won't have signal, but you'll be online to share your incredible diving photos once you're back on land.
