Yes. Houmt Souk and the resort zones along the northeast coast have reliable LTE from all three carriers. The island's interior — the road to Guellala and the lagoon areas — drops to 3G. The causeway to the mainland has continuous LTE. Download offline maps before exploring the interior villages.

No. The Sahara Desert south of Douz and Tozeur has no mobile coverage from any carrier. Tours to Chott el Djerid and Ksar Ghilane require offline navigation. Download your maps, routes, and any travel documents in Tozeur before heading into the desert.

Intermittently. SNCFT trains on the Tunis-Sousse coastal line have intermittent LTE coverage and no onboard Wi-Fi. You will have signal in stations and near coastal towns, but expect dead zones between stops. Download podcasts, videos, or offline maps before boarding.

Three to five gigabytes covers most week-long trips. Google Maps uses around 5MB per hour of active navigation. WhatsApp chats are light, but voice calls add up to 150MB per day. Bolt and InDrive use minimal data per ride. If you plan to upload photos or stream video, add two to three gigabytes.

Yes. WhatsApp voice and video calls work over the eSIM's data connection. Voice calls use roughly 600KB per minute; video calls use around 4MB per minute. The eSIM does not include a Tunisian phone number, so you cannot make traditional cellular calls, but all internet-based calling apps work normally.

Yes. Bolt operates in Tunis, Sousse, and Sfax and needs live data for driver matching and real-time tracking. The app uses around 2-5MB per ride. Make sure you have active data before requesting a ride; pre-booking on hotel Wi-Fi will not work because the driver needs to reach you in real time.

Both carriers have full LTE coverage along the Hammamet resort strip and in the town center. Tunisie Telecom has slightly wider coverage inland toward Nabeul and along the Cap Bon coast. The eSIM hands off between both networks automatically, so you get the stronger signal at each location without manual switching.

Both have strong LTE in central Sfax, the port area, and the medina. Tunisie Telecom has better coverage on the roads south toward Gabès and inland toward Kairouan. Orange Tunisia is reliable within the city limits. The eSIM will connect to whichever network is stronger where you are standing.

Yes. InDrive operates in Tunis, Sousse, and Sfax and needs live data for driver matching and GPS tracking. The app uses around 2-5MB per ride. You need active data when you request the ride and while the driver is en route; the app will not function on cached data or offline mode.

The eSIM saves you the airport queue, the passport photocopy, and the risk of losing a physical card. Airport SIM kiosks in Tunis-Carthage sell prepaid plans from Tunisie Telecom, Ooredoo Tunisia, or Orange Tunisia, but you are locked to one carrier's coverage. The eSIM hands off between all three automatically. Pricing is similar; the eSIM is faster to activate and harder to lose.

Yes. Sidi Bou Said is 20 kilometers north of Tunis and has full LTE coverage from all three carriers. The cliffside cafés and the marina have strong signal. The TGM light rail from Tunis to Sidi Bou Said has continuous LTE along the route.

Yes. Kairouan has LTE coverage from Tunisie Telecom and Ooredoo Tunisia in the city center and around the Great Mosque. Signal thins on the roads between Kairouan and Sousse or Sfax. Download offline maps if you are driving between cities.

Yes, and you should. The Sahara Desert south of Douz and Tozeur has no mobile coverage. Download the offline map area in Google Maps while you are still in Tozeur. The offline map includes roads, landmarks, and basic navigation, but it will not show real-time traffic or alternate routes.

Yes. The Hammamet medina has LTE coverage from all three carriers, though thick stone walls can block signal indoors in shops and riads. Step outside or move closer to a window if you need to load a map or call a ride. The resort strip and beach promenade have full outdoor coverage.

Around 2-5MB per ride for driver matching, real-time GPS tracking, and map rendering. If you take three or four rides per day, budget 15-20MB. The app needs live data when you request the ride and while the driver is en route; it will not work offline.
