Short answer. According to Opensignal's September 2026 report, Ooredoo has the best coverage in Tunisia at 8.0 out of 10, ahead of Tunisie Telecom at 7.8 and Orange at 6.9. In practice the gap narrows: Ooredoo and Orange users both spend 96.4% of their time connected.
The coverage ranking
Coverage, score out of 10
Source: Opensignal, data from 1 April to 29 June 2026. Orange is the network our eSIM uses.
| Measure | Ooredoo | Tunisie Telecom | Orange |
|---|---|---|---|
| Coverage (out of 10) | 8.0 | 7.8 | 6.9 |
| Time on network | 96.4% | 95.6% | 96.4% |
| Reliability (out of 1,000) | 821 | 769 | 783 |
| Consistent quality (% of tests) | 63.9% | 57.7% | 56.4% |
Coverage and time on network: what is the difference?
The coverage score shows how far a network reaches, including places few people go. Time on network shows how often its customers actually have signal. The first matters for a drive through the south, the second for everyday use. Ooredoo takes Best Network in the report, with 12 of 14 categories.
So Orange trails on coverage, but ties on connected time and comes second for reliability, with 783 points. Tunisie Telecom beats it on coverage and on consistent quality. None of these scores tells you about one beach or one village: they are national averages, so treat them as a guide to the network as a whole, not as a promise for a place. nPerf, a different method, put Tunisie Telecom and Orange joint first in its 2025 barometer: see mobile internet speed in Tunisia.
Where the network works well
| Area | What to expect |
|---|---|
| Tunis, Carthage, Sidi Bou Said, La Marsa | Urban area, 4G on all networks |
| Sousse, Monastir, Hammamet, Nabeul, Mahdia | Coastal resorts, nothing special to plan |
| Djerba, Sfax, Gabes | Good base, check isolated beaches |
| Kairouan, Bizerte, Tabarka | Towns covered, country roads more variable |
| Tozeur, Nefta, Douz, Tataouine | Towns covered, desert depends on local reach |
These towns are in our eSIM's coverage on Orange Tunisie, along with Tunis-Carthage, Enfidha-Hammamet and Djerba airports. In remote Saharan areas everything depends on local network reach, whichever operator you use.
Preparing for places with no signal
- Download offline maps before a trip into the south.
- Tell someone before you head into the desert.
- Keep bookings as screenshots.
- Leave your phone on automatic network selection.
Do not count on your usual plan as a backup in those areas either: roaming uses the same Tunisian masts. If an agency runs your desert trip, ask before you leave whether the guide carries a means of communication. A charged power bank helps too, because a phone that keeps searching for signal drains much faster.
Which network suits your trip?
For time in the Saharan south away from towns, a local operator with stronger coverage may be worth a SIM from a shop: see Orange, Ooredoo and Tunisie Telecom for tourists. For Tunis, the coast and Djerba, an eSIM on Orange does the job with no shop visit. See also 7-day prices.
Our Tunisia eSIM runs on 4G LTE on the Orange Tunisie network, with 1 GB a day at full speed then 512 Kbps until the next day, hotspot included. The 7-day plan costs €21.90 and the 10-day plan €29. It starts at your first connection in Tunisia, so install it at home on Wi-Fi, after checking that your phone is eSIM compatible.
