Zanzibar SIM Card

I was just in Zanzibar and used the Tanzacomm eSIM from Airalo. The connection was usually good enough for Google Maps, but too slow for surfing in Paje. I usually had 4G, but between the villages the network dropped back to 3G in places. I had the 10 GB package for 10 days and only used 1.26 GB - thanks to stable Wi-Fi in the hotels. There was no reception in Mikumi National Park, but you have other things in view there anyway - elephants, for example.
