Guide expert

Finding the best Comoros eSIM plan is not just about choosing the cheapest option: you also need to check the partner network, the plan’s actual validity period and your itinerary between Grande Comore, Anjouan and Mohéli. This guide helps you buy, install and use your eSIM confidently, while keeping your usual number if you wish.

How does an eSIM work in Comoros, and is your phone compatible?

An eSIM is a digital SIM card built into your phone, allowing you to buy and install a mobile plan without handling a plastic card. After purchase, the provider will usually send you a QR code, an installation link or a manual activation code. Your phone then downloads a mobile profile containing the information needed to connect to a partner network in Comoros.

The main difference from a traditional SIM is convenience: you can choose your plan, receive your instructions and install the eSIM before departure, comfortably connected to your Wi-Fi. There is therefore no need to look for a shop in Moroni after a long flight or remove your French, Belgian, Swiss or Canadian operator’s SIM card. A travel eSIM is usually prepaid: no contract, no monthly payments and no risk of unexpected charges if you disable roaming on your main line.

However, your device must support eSIM technology and be unlocked, meaning it must be free to use another operator. A recently purchased phone without a subsidy is generally unlocked, but it is best to check before paying. The eSIM can coexist with your physical SIM or usual eSIM, allowing you to keep calls and SMS on your personal number while the new line handles only mobile data in Comoros.

iPhone: iPhone XR, XS and later models generally support eSIM; iPhone 14 and newer models sold in the United States may be eSIM-only.
Samsung Galaxy: many Galaxy S, Z Fold, Z Flip and some newer A models are compatible; check the exact specifications of your variant, as this varies by country of purchase.
Google Pixel: Pixel 3 and later generations usually support eSIM, provided they are not locked to an operator.
Other brands: some newer Xiaomi, Motorola, Huawei, Oppo and Sony models offer eSIM, but compatibility depends heavily on the model and regional version.
In your settings, look for “Add eSIM”, “SIM Manager” or “Mobile Network”. You can also dial #06#: the presence of an EID is a good indicator of eSIM compatibility.
Check with your current operator that your phone is unlocked before travelling: a locked mobile may accept profile installation but refuse to connect to the network.

Which eSIM should you choose for the best mobile coverage in Comoros?

To get the best coverage with an eSIM in Comoros, first choose a provider that clearly states its local partner network, rather than focusing only on the amount of data included. The country’s mobile networks notably include Telma Comores and Comores Telecom. An international eSIM relies on one of these operators while roaming, so two seemingly similar plans may offer very different experiences depending on the selected partner.

In and around Moroni, on Grande Comore, as well as in the main urban centres of Anjouan and Mohéli, 4G is generally the realistic option to look for. For everyday use—messaging, maps, bookings, social media and WhatsApp calls—good 4G is more than sufficient. 5G should not be a decisive factor: its commercial availability and actual rollout remain far less consistent than in major European or Asian destinations. A plan advertising “5G where available” never guarantees a 5G connection on site.

The archipelago’s geography has a tangible impact on your connection. Grande Comore’s volcanic terrain, secondary roads, remote villages, less populated coastal areas and sea crossings can weaken the signal. Between Moroni and tourist areas accessible by road, a usable connection is often possible, but it may switch from 4G to 3G or become unstable as soon as you leave inhabited areas. On Mohéli, a more rural and less densely populated island, expect more outages and avoid relying exclusively on the cloud.

Speeds vary depending on the weather, the chosen network, the time of day and local congestion. A good 4G connection may allow you to download offline maps in a few minutes or make a video call, but it would be unwise to rely on a stable connection for continuous remote work, sending very large files or streaming high-definition video. Download your documents, maps and tickets whenever you have reliable Wi-Fi or a strong mobile signal.

Moroni and the main urban areas of Grande ComoreGenerally the strongest mobile coverage; 4G is often available depending on the partner network and congestion.

Mutsamudu, Fomboni and inhabited centres of Anjouan and MohéliConnection is usually suitable for navigation and messaging, with variations depending on the neighbourhood.

Main roads, busy coastline and tourist areasSignal is often adequate but intermittent; download your content before travelling.

Remote villages, volcanic terrain, inland areas and seaNetwork may be weak or unavailable; do not rely on data for urgent navigation or bookings.

Before purchasing, check whether the provider displays the local partner, the expected network type and any mention of manual network selection.
Upon arrival, initially leave network selection on automatic; if the Internet does not start, manually try Telma Comores and then Comores Telecom.
Download Google Maps or Maps.me for Grande Comore, Anjouan and Mohéli before leaving your accommodation or the airport.
For business travel, prepare a backup plan: hotel Wi-Fi, a second eSIM or a workspace in a well-covered urban area.
Do not judge a plan after a single airport test: wait until you are outside and restart the connection if the signal remains weak.

Should you choose a Comoros eSIM or a regional Africa plan?

A dedicated Comoros eSIM is generally the most logical choice if your stay is limited to the archipelago: it may offer a better balance between data allowance and price while using a specific local network. It is ideal for a stay in Moroni, a trip between Grande Comore and Anjouan, or a holiday focused on Mohéli. Nevertheless, check that “Comoros” appears in the list of covered destinations: Africa plans do not all include the same countries.

A regional Africa plan becomes more attractive if Comoros is just one stop on your itinerary. This may be the case when travelling via Mayotte, Madagascar, Tanzania, Kenya, Mauritius, Réunion or South Africa. You avoid installing several profiles and remain connected during a stopover or immediately after landing in the next country. In return, the price per gigabyte may be higher and the partner network may vary from one country to another.

Global plans can also be convenient for a long trip with connections in Europe, the Middle East or East Africa, but they are not automatically the best value. Their main advantage is roaming continuity, not necessarily the amount of data. Always read the list of covered territories, as Mayotte and Réunion are administratively French but may be treated as separate destinations by providers.

Choose a national plan if you are staying only in Comoros and want the largest data allowance.
Choose an Africa eSIM if you are continuing on to Mayotte, Madagascar, Tanzania, Kenya, Mauritius or South Africa.
Check the list country by country: “Africa” does not automatically mean that Comoros is included.
For a stopover, also check whether data works in the transit country and whether the plan starts upon the first connection.

What should you really expect from reviews of eSIMs in Comoros?

Reviews of eSIMs in Comoros mainly show that travellers appreciate their installation before departure and the lack of local formalities on arrival. Travellers who prepared their phone over Wi-Fi, saved the QR code and downloaded their maps offline generally enjoy a straightforward setup. For a short stay, an eSIM also saves you from having to understand local top-up conditions or find an open shop.

More mixed reviews rarely concern the eSIM itself: they often reflect the limitations of actual coverage in a mountainous archipelago that is less densely equipped than major tourist destinations. A plan may work perfectly in Moroni, then become slow or unavailable on a secondary road, in a remote village or during inter-island travel. It is therefore important to distinguish a configuration issue from a local lack of signal.

Support is an important factor, especially if you travel outside European business hours. Choose a provider offering support via chat or e-mail, with clear APN instructions and troubleshooting procedures. The cheapest plans may be excellent for messaging, but they do not always provide the most detailed information about the network, tethering or refund conditions.

Recurring positive point: remote purchase and installation before boarding the plane.
Recurring positive point: keeping your usual SIM for calls and SMS codes.
Point to watch: a good experience in Moroni does not guarantee the same speed on every island.
Point to watch: read the support, top-up and refund policies before activation.

How do you buy, install and activate your eSIM for Comoros?

Installing an eSIM for Comoros often takes less than ten minutes, provided you prepare it over Wi-Fi before departure and do not activate data too early.

1
Check compatibility
Before choosing a plan, check that your phone is eSIM-compatible and unlocked. In the settings, look for the “Add eSIM” option; if it is missing, check the manufacturer’s website. Also make sure your phone supports two active lines if you want to keep your main number.
2
Buy and receive the QR code before departure
Purchase your plan over a stable connection and keep the confirmation e-mail available offline. The QR code is often for one-time use: do not share it or delete it after installation. Take a screenshot of the instructions, manual code, any APN details and the support contact information.
3
Install the profile on iPhone or Android
On iPhone, open Settings > Cellular > Add eSIM, then choose “Use QR Code”. On Android, the path is generally Settings > Connections or Network & Internet > SIM Manager > Add eSIM, but labels vary between Samsung, Pixel and other brands. Give the line a clear name, such as “Comoros eSIM”, so you do not confuse it with your usual line.
4
Activate on arrival and configure the APN
You can install the profile before your flight, but activate its line and set it as the mobile data line only upon arrival, unless the provider specifies otherwise. Enable “Data Roaming” for the travel eSIM: this is normal because it connects to a partner network. The APN is often configured automatically; if it is provided in the instructions, enter it exactly in your mobile network settings.
5
Troubleshoot if the Internet does not start
Start by turning airplane mode off and on again for around thirty seconds, then check that the eSIM is selected for cellular data. Check roaming for this line, disable data on your main SIM and try manually selecting a network if permitted. If this fails, check the APN, restart the phone and contact support with screenshots, without deleting the eSIM before receiving their instructions.

Can you keep your number, make calls and share your connection in Comoros?

Yes, you can keep your usual number with a travel eSIM, as most Comoros eSIM plans are data-only and support dual SIM functionality. Keep your main SIM active for incoming calls and important SMS, but disable its mobile data and roaming to avoid international charges. In the settings, explicitly select the Comoros eSIM as the default data line.

A data-only eSIM generally provides neither a Comorian number, cellular calls nor standard SMS. This does not prevent you from communicating: WhatsApp, Signal, Telegram, FaceTime Audio, Messenger and other voice-over-IP applications work with data. Your WhatsApp account remains linked to your existing number; do not agree to replace it with a temporary number when the app suggests it.

Tethering is often possible, but you should confirm this in the plan’s conditions. Activate the personal hotspot only when needed: a computer can consume several gigabytes in a few hours because of backups, system updates or cloud synchronisation. Block automatic updates, disable high-quality video playback and use a strong hotspot password.

If you are nearing your limit, monitor usage both in the provider’s app and in your phone’s settings. Most providers allow a top-up or the purchase of a new plan, but the process is not universal: some add data to the same profile, while others require a new eSIM. Do not wait until the last megabyte, especially if you are heading to Mohéli or an area where finding Wi-Fi may be difficult.

Set your usual SIM for calls and SMS, and the Comoros eSIM for mobile data.
Disable roaming on your main line; enable it only on the travel eSIM.
WhatsApp keeps your number: use it for calls and messages without buying a local number.
Before using the hotspot, check that your plan allows tethering and disable updates on your computer.
Keep at least a few hundred MB for a taxi, booking, map or emergency contact.

What criteria should you use to choose the best Comoros eSIM plan and avoid mistakes?

To estimate your needs, allow around 1 to 3 GB for a few days of messaging, maps and searches, 3 to 7 GB for one to two weeks with social media, and more if you share your connection or watch videos.

Do not choose based solely on the advertised price: compare the price per gigabyte, validity period, top-up policy and partner network. A very cheap small plan becomes expensive if you need to renew it several times.
Adjust the allowance to your actual usage. Maps, messages and e-mails use little data; videos, video calls, photo backups and hotspots can use up 5 GB much faster than expected.
Check the exact validity period: some plans last 7, 15 or 30 days from activation, while others may start upon installation or on a specified date. Do not scan the QR code at the last minute without reading this rule.
Prepare your phone before flying: install the profile, keep the instructions and download offline maps. In Comoros, an unstable connection should not prevent you from finding your hotel or driver.
Read “unlimited” policies carefully. The word unlimited may conceal reduced speeds after a certain daily allowance, hotspot restrictions or fair-use rules.
Do not confuse coverage with performance. Even with an excellent plan, terrain, buildings, a power cut or a sparsely populated area can limit the signal; allow extra data and have an offline backup plan.
Disable data-hungry features: automatic photo backups, app updates, autoplay videos and cloud synchronisation. Enable data saver mode on both your phone and your applications.
Never delete a malfunctioning eSIM in a panic. Many QR codes cannot be reused; contact support first and keep screenshots of your settings.
If you are travelling between islands, keep essential documents offline and warn your loved ones that there may be periods without network coverage. An eSIM is very practical, but it does not replace preparation suited to an archipelago.

Questions fréquentes

Will the eSIM work as soon as I arrive at Moroni airport?

In principle, yes, if your plan covers Comoros, the line is activated and data roaming is enabled for the eSIM. However, the signal may vary inside the terminal, so test it outside as well.

When does my eSIM plan’s validity begin?

It depends on the provider: validity often starts when you first connect to a local network, but sometimes it begins upon installation or purchase. Check this condition before scanning the QR code.

Can I install the same eSIM on two phones?

No. In most cases, an eSIM profile is intended for one device only. To connect a second phone, use the hotspot if your plan allows it or buy a second eSIM.

Do emergency numbers work with a data-only eSIM?

Do not rely on a data-only eSIM for emergency calls. Keep your main SIM available, ask your accommodation for useful contacts and note assistance information before travelling to isolated areas.

Can I get a refund if my eSIM does not work?

Refunds depend on the seller’s terms and are often limited after activation or data usage. Keep evidence of the problem, contact support promptly and do not delete the profile before receiving their instructions.
