Eswatini has two main mobile operators: Eswatini Mobile (formerly Swazi MTN) and Eswatini Telecom (under the brand ESWATINI). HelloRoam eSIMs connect via partner networks where available in Eswatini.
4G LTE coverage exists in Mbabane, Manzini, and along the main corridors connecting these cities. The MR3 highway between Mbabane and Manzini has continuous 4G. Smaller towns like Siteki, Pigg's Peak, and Big Bend have 3G coverage.
Hlane Royal National Park has limited signal near the camp area. Mlilwane Wildlife Sanctuary, which is the most popular park and located between Mbabane and Manzini, has 4G in the main camp area. Mkhaya Game Reserve in the east is more remote with weaker signal. The Malolotja Nature Reserve in the northwest, known for hiking, has very limited coverage on its trail network.
Given Eswatini's small size, crossing from South Africa on the Ngwenya border post or Oshoek post means transitioning from South Africa's strong network to Eswatini's coverage. Download offline maps before entering.
