The Tunisian dinar, designated TND and divided into 1000 millimes, functions as the sole legal currency within Tunisia since its introduction in 1958 to replace the Tunisian franc at a rate of 1000 francs per dinar. The Central Bank of Tunisia issues banknotes in denominations of 5, 10, 20, 50 dinars and coins in 5, 10, 20, 50, 100, 200, 500 millimes plus 1 and 5 dinar pieces. Exporting or importing Tunisian dinars remains prohibited by law under Decree 77-608 of July 1977, requiring travelers to conduct all currency exchange within the country's borders and to declare amounts exceeding 5000 dinars equivalent on entry. Exchange receipts issued by authorized banks and exchange offices must be retained for reconversion purposes and customs clearance, with reconversion limited to 30 percent of the original exchanged amount and only possible at the point of departure within Tunisia.
Commercial banks operate Monday through Friday typically from 0800 to 1500 during winter months September through June and 0730 to 1330 in July and August, though individual branches vary these hours. Major banking institutions include Banque de l'Habitat covering 92 branches nationwide as of 2023, Société Tunisienne de Banque with 118 branches, Banque Internationale Arabe de Tunisie operating 125 branches, Attijari Bank maintaining 146 branches, and Banque de Tunisie with 115 locations. Airport exchange offices at Tunis-Carthage International Airport remain open to align with flight schedules, providing services during arrivals and departures beyond standard banking hours. The exchange rate floats managed by the Central Bank with interventions, reaching approximately 3.08 dinars per US dollar, 3.35 dinars per euro as of December 2023, though rates fluctuate based on market conditions and central bank policy adjustments.
ATMs designated as guichets automatiques bancaires or GAB distribute dinars throughout urban centers and tourist areas, with Visa and Mastercard accepted more reliably than American Express or Discover networks. Daily withdrawal limits vary by bank and card type, ranging from 500 to 1500 dinars per transaction with typical daily maximums of 1000 to 2000 dinars across the network. Withdrawal fees include both issuing bank foreign transaction charges typically 1 to 3 percent plus fixed fees of 3 to 5 dollars or euros, and local bank operator fees of approximately 3 to 7 dinars per transaction. ATMs appear concentrated in Tunis medina and ville nouvelle districts, along Avenue Habib Bourguiba, in Sousse along Boulevard de la Corniche, throughout Sfax commercial center, in Monastir near the marina and airport, across Hammamet resort zones, and in Djerba at Houmt Souk. Rural areas including interior towns approaching the Sahara Desert and smaller villages in the Atlas Mountains regions may lack ATM access entirely, requiring cash planning before departure from urban centers.
Credit cards see acceptance at hotels rated three stars and above, international restaurant chains, car rental agencies operating from airports, and larger shops in tourist zones, while Tunisian society operates predominantly on cash for daily transactions. Restaurants outside tourist areas, transport including louages shared taxis and SNCFT trains, souks and medina shops, street food vendors, and most service providers require dinar payment. Dynamic currency conversion offered at some point-of-sale terminals converts charges to home currency at unfavorable rates, making selection of local currency charges preferable to avoid conversion markups of 3 to 5 percent above interbank rates.
Cash requirements for travelers vary by itinerary and accommodation style, with budget estimates suggesting 50 to 100 dinars daily covers meals at local restaurants, public transport, market purchases and entrance fees to archaeological sites and museums, while mid-range spending of 150 to 300 dinars per day accommodates higher-standard restaurants, private transport, and organized excursions. A meal of lablabi chickpea soup costs 2 to 3 dinars at neighborhood eateries, a brik fried pastry runs 3 to 5 dinars from street vendors, full couscous meals range 8 to 15 dinars at modest restaurants, and upscale dining in Tunis or Sousse reaches 30 to 60 dinars per person. Louage shared taxi fares from Tunis to Sousse cost approximately 7 to 9 dinars, Tunis to Kairouan runs 8 to 10 dinars, while private grand taxi rates negotiate but typically double or triple shared taxi costs for equivalent routes. Entry to the Bardo National Museum charges 13 dinars for non-residents, the Amphitheater of El Jem requires 12 dinars, Dougga archaeological site costs 10 dinars, and combined tickets to Carthage sites run 12 dinars covering multiple locations including the Antonine Baths and Tophet sanctuary.
Tipping termed pourboire follows customary practices in service industries, with restaurant gratuity of 10 percent appropriate when service charges are not included on bills, though checking receipts remains necessary as some establishments add service automatically. Hotel porters receive 2 to 3 dinars per bag, housekeeping staff 5 to 10 dinars per room stay placed in envelopes, taxi drivers do not expect tips but rounding up fares gains appreciation, and tourist guides receive 10 to 20 dinars per person for half-day excursions and 20 to 40 dinars for full-day tours depending on group size and service quality.
Mobile network infrastructure covers populated areas through three primary operators: Tunisie Telecom, the state-owned incumbent serving approximately 4.8 million mobile subscribers as of 2023, Ooredoo Tunisia operating under the Tunisiana brand until rebranding in 2013 and serving roughly 4.2 million subscribers, and Orange Tunisie entering the market in 2010 and reaching approximately 3.1 million customers. 4G LTE coverage reaches 95 percent of the population concentrated in coastal regions and major cities, while 3G networks extend into rural areas with gaps appearing in remote Sahara regions south of Douz and Tataouine and mountainous areas of the Dorsale range. 5G deployment began in Tunis and Sousse in 2022 through Tunisie Telecom and Ooredoo with limited coverage areas as of 2024.
Prepaid SIM cards termed cartes prépayées require passport presentation for registration under telecommunications regulations enforced since 2017, with purchase available at operator branded stores, authorized resellers, and post offices throughout Tunisia but not at Tunis-Carthage International Airport arrivals area where no official sales points exist as of 2024. SIM card prices range 5 to 10 dinars including minimal credit, with identification registration completing immediately at point of sale through database entry. Data packages vary by operator with typical offerings including 5 gigabytes valid 30 days costing 15 to 20 dinars, 10 gigabytes monthly running 25 to 30 dinars, and 20 gigabytes ranging 40 to 50 dinars across providers. Recharge cards termed recharges purchase at tobacco shops, grocery stores, post offices, and operator retail locations in denominations of 5, 10, 20, 50 dinars. International calls to European numbers cost approximately 0.400 to 0.600 dinars per minute, North American destinations run 0.800 to 1.200 dinars per minute on standard prepaid rates before promotional packages.
WiFi availability appears standard at hotels across star categories, many cafes particularly in Tunis along Avenue Habib Bourguiba and in Sidi Bou Said village, restaurants catering to tourists in Sousse medina and Hammamet resort areas, and at Publinet internet cafes still operating in smaller cities despite declining numbers. Connection speeds vary substantially, with fiber optic infrastructure deployed by Tunisie Telecom reaching advertised speeds up to 100 megabits per second in residential areas of Tunis, Sfax, and Sousse, while ADSL connections of 4 to 20 megabits predominate in secondary cities and actual speeds frequently fall below advertised rates. Public WiFi hotspots operate in Tunis-Carthage International Airport terminals, select Tunisian National Railways SNCFT stations including Tunis-Ville, and coastal promenade areas in Monastir and Sousse installed through municipal initiatives.
