Cape Town is served by Vodacom, MTN South Africa, and Cell C, with Vodacom providing the widest coverage across the metro. The City Bowl including the CBD, De Waterkant, Gardens, and Tamboerskloof has strong 4G.
The V&A Waterfront, the Clock Tower area, and the Two Oceans Aquarium zone have excellent outdoor signal. The Atlantic Seaboard from Green Point through Sea Point, Bantry Bay, Clifton, and Camps Bay has consistent 4G.
The Southern Suburbs including Claremont, Constantia, and Tokai have solid coverage. Stellenbosch, Franschhoek, and Paarl in the Cape Winelands have 4G in the main town areas. Table Mountain's cable car upper station has limited coverage.
Hiking trails on Table Mountain, Lion's Head, and Signal Hill can lose signal in certain sections. Cape Point and the Cape of Good Hope are very remote and have limited or no coverage.
Load shedding (power cuts) can affect network towers during extended outages, so download offline maps as a precaution.
