How to verify eSIM support on your device

1. iPhone: Settings → Cellular → look for "Add eSIM" or "Add Cellular Plan". You can also dial *#06# , if you see an "EID" (32-digit number), your phone has eSIM hardware.
2. Android: Settings → Connections (or Network & Internet) → SIM Cards → look for "Download a SIM instead" or "Add eSIM".
3. EID check: most eSIM-capable Android phones show EID in Settings → About Phone → Status.

Tip: Even if your phone supports eSIM hardware, it must be unlocked (not carrier-locked) to use third-party eSIMs like Cellesim. Most phones bought outright are unlocked; phones from carrier instalment plans may require unlocking after the contract is paid off.

Almost every flagship smartphone released since 2019 supports eSIM, making it ideal for international travel. Compatible models include iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, plus a growing list of mid-range devices. If your phone has Settings → Cellular → "Add eSIM", you're ready to use a Cellesim plan abroad.

Travellers benefit most from eSIM because it eliminates the airport SIM-card queue, removes the need to swap your home SIM out, and lets you keep your usual phone number active for SMS verification. A Cellesim travel eSIM activates the moment you land , no shop visit required.

Tip: if your current phone doesn't support eSIM but you travel often, an unlocked, mid-range eSIM-capable phone (e.g., Pixel 7a, iPhone SE 3, Samsung Galaxy A55) makes an excellent secondary travel device , pair it with a Cellesim plan and you have a full mobile internet kit for any destination.

Yes, in key areas. This is the #1 concern for visitors. Our eSIM connects to local networks (like Orange Bissau) which have towers on the main inhabited islands, including Bubaque and Rubane. While you will have a signal in the main villages and lodges, please expect "dead zones" when on boat transfers or visiting remote, uninhabited islands. It is reliable for messaging, but not for heavy streaming. 

 This specific plan is valid only within Guinea-Bissau. This is critical as many travelers enter overland from Ziguinchor (Senegal) or Boké (Guinea). Your connection will stop at the border. For a seamless overland journey, we highly recommend our Regional West Africa eSIM to stay connected across all borders. 

No. This is a major advantage. Buying a physical local SIM card in Bissau requires visiting an Orange or MTN shop, navigating the language barrier (Portuguese/Creole), and going through a mandatory passport registration process. Our eSIM is a roaming plan that bypasses all this bureaucracy. You can install it before you fly and be connected instantly. 

 In a country with developing infrastructure, network choice is vital. Our eSIM connects to the country’s top-tier providers, typically Orange Bissau or MTN. Orange is generally considered to have the most reliable 4G signal in the capital, Bissau, and the best overall coverage in the country. 

Yes, almost always. The internet infrastructure in Guinea-Bissau is fragile. Hotels and guesthouses suffer from frequent power cuts, which kills the Wi-Fi. Mobile towers often have backup generators. An eSIM is your "lifeline," providing a stable connection for WhatsApp and Google Maps when all other Wi-Fi is down. 

 Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing. 

 No, Uber does not operate in Guinea-Bissau. You need reliable data to find landmarks on Google Maps to direct traditional taxi drivers (often blue and yellow Mercedes) effectively. 

 Yes. You will generally have signal near the bridge and the Pousada do Saltinho, allowing you to share videos of the Corubal River rapids instantly. 

 Yes. Coverage is strong in Bissau city center, allowing you to live-stream the colorful masks and parades of the famous Carnival (Carnaval de Guiné-Bissau) in February. 

 Yes. Coverage is generally reliable in the historic town of Cacheu, allowing you to access digital guides while visiting the fort or the Tarafes de Cacheu mangrove natural park.
