Rwanda eSIM

Yes, and it is completely routine for people living there, with both cars and motorcycle taxis available; the bikes are quicker in rush hour. What you should do is register and verify the account before you travel, since verification usually sends a code by SMS to your own number. Once you arrive, the eSIM's data is enough to book rides, and it is worth carrying some cash for drivers who prefer it.

Mostly not, because walking through bamboo and montane forest cuts the signal for most of the route, and park rules ask you to put equipment away and stay quiet as you approach a family of gorillas. The better plan is to tell people at home in advance that you are unreachable from morning until mid-afternoon, keep your documents and meeting point saved on the device, and send word once you are back in Musanze or at your lodge in the evening.

It works normally while you are on the Rwandan side, at Rubavu or Karongi for instance. Right at the border, though, a phone can latch onto a neighbouring country's network on its own, which quietly takes you outside the plan's coverage area. If that happens, switch network selection from automatic to manual and pick the local network yourself; and if you actually intend to cross, buy a plan that names the country you are heading into.

Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.

No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
