Rusizi, built around the town of Cyangugu at the southern end of Lake Kivu, is one of Rwanda’s more out-of-the-way destinations — reached by a long, winding road through Nyungwe Forest or by a short domestic flight into Kamembe, and separated from the Congolese city of Bukavu by little more than a bridge.
Quick answer: Cyangugu itself is more remote than it looks on a map, and coverage reflects that — workable 4G in town, generally 10-20 Mbps, but nothing like the density of towers you’d find further east. Given the limited dealer options this far southwest, arrive with your SIM or eSIM already sorted rather than planning to set one up locally.

Coverage in Cyangugu
The town center around Cyangugu has functional 4G from MTN and Airtel, sufficient for messaging, maps, and light browsing, though speeds and consistency trail the more developed towns further east. Kamembe, home to Rusizi’s small domestic airport, has similar coverage to the town proper.
The Nyungwe approach
Most visitors reach Rusizi by driving the long forest road through Nyungwe National Park, and signal along that stretch is patchy at best, dropping out entirely in places for extended periods — the Nyungwe internet guide covers that route in detail. Treat the drive itself as a stretch without reliable connectivity rather than an exception.
The border with Bukavu, DRC
Rusizi’s proximity to Bukavu across the border means, similar to Rubavu further north, that phones near the crossing can occasionally register on a Congolese network instead of a Rwandan one. Checking which carrier your phone is actually connected to near the border avoids being charged international roaming rates unexpectedly — see the roaming charges guide for how to check this.
Getting connected before you arrive
Because Rusizi has fewer authorized SIM outlets than Rwanda’s larger towns and cities, most visitors either buy a SIM in Kigali before the long drive down, or travel with an eSIM already installed and activated, avoiding any need to hunt for a dealer once they arrive.
Using Rusizi as a base
Rusizi works mainly as an endpoint for a Nyungwe forest itinerary or a quieter, less-visited stretch of Lake Kivu, rather than a standalone destination most travelers build a trip around. For the wider Lake Kivu picture, including the busier towns further north, see the Lake Kivu internet guide.
FAQ
Is there mobile coverage in Cyangugu/Rusizi?
Yes, though it’s more modest than Rwanda’s larger towns — expect workable but not fast 4G.
Will I have signal driving through Nyungwe to reach Rusizi?
Coverage along that road is patchy and drops out in places, so plan for stretches without connectivity.
Can my phone connect to a Congolese network near the border?
Yes, similar to Rubavu further north, phones near the Bukavu crossing can occasionally register on a foreign network.
Should I buy a SIM in Rusizi or beforehand?
Beforehand — dealer options in Rusizi are limited compared to larger Rwandan towns.
Is there an airport in Rusizi?
Yes, Kamembe Airport offers domestic flights, with coverage similar to the town itself.
Is Rusizi worth visiting on a Nyungwe itinerary?
Many travelers use it as an endpoint after exploring Nyungwe or a quieter alternative to Lake Kivu’s busier northern towns.
Final Recommendation
Rusizi rewards travelers who arrive already connected, given how limited local SIM options are and how patchy the approach road through Nyungwe can be. See the Nyungwe internet guide before making the drive down.
