São Tomé and Príncipe, officially the Democratic Republic of São Tomé and Príncipe, is a Portuguese-speaking island nation in the Gulf of Guinea, off the western equatorial coast of Central Africa. It consists of the two major islands São Tomé and Príncipe and some smaller islands around.
Two mobile operators are present on the islands:
- Unitel STP
Mobile phones (called telemóvels) are everywhere and coverage is pretty good. All populated areas are covered, but there are blank spots on the countryside and on Principe. CTS has the better network. Since the arrival of the fibre-optic cable in 2013 internet speed has improved considerabely.
SIM cards (called Cartãó Beijo) are available from the providers in Sao Tome city and in Santo Antonio (on Principe). They cost around nDb 50 plus some preloaded credit. Registration is mandatory and it can take up to 3 hours for the SIM to activate after registration. Top-ups (called recargas) are usually sold from nDb 50 in several small shops and kiosks that display the logo of the providers.
IDD calls are very expensive and some countries can only be connected through an operator. So better use VoIP like Skype or WhatsApp for calling international.
On the 1st January 2018 the Central Bank of São Tomé and Príncipe did a redenomination of the national curreny dobra, with 1 new dobra (nDb) equal to 1,000 of the previous dobras. Prices for CST are given in new dobra, while Unitel still advertises old dobra (STD).
CST (for Companhia Santomense de Telecomunicações) is the incumbent and largest operator in Sao Tome and Principe. It manages the landline and internet connections too and is co-owned by the STP government and Africatel.
They offer GSM/EDGE on 900 MHz and started UMTS/HSPA on 2100 MHz in 2013, no 4G/LTE yet. Speed on prepaid is limited to 1 Mbps. They are generally considered to be the better provider with the best coverage at similar rates than Unicel.
SIM cards are sold in CST shops (list of shops.). They cost nDb 80 STD and come with nDb 50 credit. They have several different plans for voice. For data it doesn't matter much which one you choose but the plan "LEVE-LEVE" has the longest credit validity which is useful, so you're not cut off in the middle of using your data.
In addition to CST shops, independent agents sell both direct top-ups and recharge vouchers. To top-up by vocuher, enter *128*<voucher code>#.
