Eh, I'm in South Africa and mobile and fibre internet work well for me during loadshedding (This goes for gmail, Slack, etc.).

> Also sometimes phone calls and very frequently SMS messages would not go through in many parts of South Africa including Cape Town

You say in many parts, really? What other parts?

Maybe get a local SIM if where you're staying doesn't have fibre; is this not a T-Mobile issue?

This is likely a TMobile issue since the connection gets proxies back to the US when using their roaming service, which slows things down a lot.
