Comoros is an island off the coast of East Africa that's extremely popular with both African and Arab visitors. Using your home phone network there can be expensive, so consider switching to a local SIM card to take advantage of cheaper local tariffs. Comoros has some reasonably priced prepaid SIM card offers, including deals that could reduce your bills. You can buy 1GB of data for KMF5,250 (AUD$16), which is no doubt cheaper than your current roaming rates abroad. So, whether you’re planning a holiday or just a quick trip, check out the best SIM card options available.

Telco providers in Comoros

There are two main operators in Comoros: Huri and Telma. Both have been tried and tested by locals, travellers and leading testing sites, and can be trusted. According to OpenSignal’s connectivity report, Comoros has strong network coverage around the Moroni area, but it can become weaker the farther out you head. Large areas of the island are still not covered by a network at all, especially around the shoreline.

About the Comoros operators

Both operators sell prepaid credit, which allows users to take advantage of local offers and deals. Roaming rates can be a little high compared to what is normally expected of operators, so make sure you compare deals against your own provider before committing. Both networks offer 2G and 3G wireless services, but Telma also offers 4G. Locals call their SIM cards “SIMSIMs”, and there are no rules and regulations when purchasing them. Tourists can buy SIM cards from almost anywhere on the island, at supermarkets, street sellers and stalls. However, we advise you to purchase them only from official stores to avoid unwittingly picking up a fake SIM card.

Huri (Comoros Telecom)

Huri is the main provider on the island, owned by Comoros Telecom. It offers customers a good 2G and 3G service, but 4G/LTE hasn’t even been talked about yet. The network bans VoIP calls, so be prepared for a Skype blackout unless you manage to find a good Wi-Fi signal. Customers often complain about the poor services this operator provides, and until the introduction of its competitor Telma, prices were astronomical.

SIM cards can be purchased on arrival at the airport, after baggage reclaim. Official stores and approved resellers also sell them. SIMs cost KMF4,000, and credit must be added before use. Credit can be purchased from most stores and supermarkets across the island. Dial 333 to activate the SIM card. Dial #123# to check your balance.

Telma (Telecom Malagasy)

Telma is the only other provider on the island. Although it has the smaller market share, it’s definitely the better provider, offering 2G, 3G and 4G/LTE services. VoIP calls are open, and the brand offers cheap deals to call nearby islands or the African mainland. The only problem is that once you head out toward the shoreline, the signal can be extremely hard to find. SIM cards can be purchased for KMF4,000, and credit must be added to use them. Top-ups can be purchased from almost anywhere on the island, but stick to the official stores, supermarkets and approved resellers to avoid illegal street selling.

The Karibu data add-on packs are a welcomed bonus and can be purchased for KMF4,000. They include 60 free minutes, plus 100 SMS and 1GB of data, valid for 30 days. Dial *445*50# to activate.

The following TelmaNet options can also be added:

Telma’s website is in French:

Some top tips from staff:

  • Comorian, French and Arabic are spoken on Comoros. Comorian is spoken locally, so you might want to download Google Translate onto your phone before you travel. The good news for many tourists is that French and Arabic are also used, and most people on Comoros speak English.
  • Locals call their SIM cards “SIMSIMs”.
  • Ask the official sellers to set up the SIM for you, because they will know how to do it. If not, follow the instructions above or go to the official website for advice.
  • Make sure you purchase your SIM card from official stores. Top-up vouchers are trusted from chain supermarkets and approved resellers. Try to avoid street sellers.

Pros and cons of the Comoros telco providers

Both networks require you to have a SIM-unlocked, GSM-compatible phone. To double check you have this phone or whether it can be unlocked, contact your provider before you leave.


  • Prepaid credit when required.
  • No in-store contract needed.
  • Could be compatible with your current phone.


  • Can be expensive. Compare roaming rates with your current provider to make sure it’s cheaper.

  • Can only be used on SIM-unlocked GSM phones.
  • Avoid street sellers.

Q: Can Comoros plans be used on mainland Africa?

A: We suggest only using the two SIM providers we mentioned while on the island, and once you hit the mainland, purchase one of the SIM cards available there.
