The Cederberg is a short drive from Cape Town and a long way from a mobile network. The main road along its western side has signal most of the way; turn off into the mountains and it fades, then goes. This is what phones with LastBar measured there.
What phones found
When this page was written, on 26 October 2026, phones had measured 237 spots of about 0.1 km² within 25 km of the middle of the Cederberg. By the best signal of any carrier: 59 with no signal at all, 44 weak, 101 fair, 32 good and 1 excellent. The box above shows the figures as they are today.
- Along the N7 on the western side, between Citrusdal and Clanwilliam, the signal was mostly fair, and good in places.
- Into the mountains, toward the campsites and forestry station in the valley, it was weak to fair, with gaps.
- On the roads east toward Wupperthal, every spot phones measured had no signal.
What that means for a trip
- Expect to lose signal soon after leaving the main road, and to have none on many hiking routes and in the eastern valleys.
- Make your calls and send your plans before you head in.
- Save the area in LastBar before you go: its Find Signal can then give you the distance and direction to the nearest signal with no connection. In an emergency it looks at every carrier, since an emergency call can use any network in reach.
- For multi-day hikes in the back country, carry a satellite messenger or a personal locator beacon.
These are what phones measured, a day old as the public map shows them, and not a promise: signal changes with the weather, the season and the network. Every trip with LastBar fills in more of the map.
