eSIM for travelling in South Africa not working

[HelsC]

Hello, I have purchased a travel (non-O2) SIM to use for 30 days while I am travelling in South Africa. I have loaded it onto my iPhone, but I received a message saying it has not been activated. Any suggestions of how to fix? Do you think it will fix itself once I arrive in SA?

Thanks

You need to speak to whoever the esim provider is, however, if you have an  O2 physical sim in your phone, try removing it first to activate the esim.
