There are no local telephone codes in Tunisia.
Despite the widespread adoption of mobile phones, public phones are still common – look for Publitel offices, which are prevalent across the country and contain rows of telephone booths. Public telephones (also known as taxiphones) accept 100-mill, 500-mill, one-dinar and five-dinar coins.
The best GSM operators are Orange (www.orange.tn), Tunisie Telecom (www.tunisietelecom.tn) and Ooredoo (www.ooredoo.tn).
Mobile-phone coverage is excellent (including 4G), apart from in the desert and deep countryside.
Local SIM cards with data packages start at 5DT. You'll need to show your passport to buy a SIM.
