Unlike buying a physical SIM card at the airport kiosk—which requires waiting in line and scanning your passport for registration—Cellesim eSIM does not require ID registration for data-only plans. You can buy it online and install it within minutes, skipping the paperwork and airport queues completely. 

Answer: Yes! Almost all Cellesim plans support the "Personal Hotspot" feature. You can freely share your internet data with your family, friends, or your other devices like tablets and laptops. 

Answer: No, absolutely not. Cellesim eSIM provides data only; it does not change your phone number.

Important Tip: When using the new eSIM, WhatsApp might ask you, "Do you want to update to the new number?". You must select "Keep My Number". This way, all your chats, groups, and contacts will remain exactly as they are.

Answer: Yes, you can easily top up your active plan. Simply log in to the "My eSIMs" section on our website and select the eSIM you wish to extend.

Important: Top-ups are only possible for eSIMs that are currently active. If your plan's validity period has already expired, you cannot top it up; you will need to purchase a new eSIM package.

 Most modern smartphones released by Apple, Samsung, and Google in recent years are compatible with eSIM technology. To be sure if your specific model is compatible, please check our complete [list of eSIM supported devices]. 

Answer: Activation is a simple two-step process:

1. Installation (Before You Fly): Scan the QR code sent to your email (Settings > Mobile Data > Add eSIM). We recommend doing this at home or at the airport while you have Wi-Fi.
2. Activation (Upon Arrival): Once you land, select your Cellesim line as your "Mobile Data" source. Most importantly, turn ON "Data Roaming" in your phone settings for the new eSIM to start the connection. Note: Your data plan validity only begins when you connect to the network at your destination.

Answer: Yes, absolutely. Thanks to Dual SIM technology, you can keep your physical SIM card active alongside your Cellesim eSIM.

Best Practice: We recommend setting your Physical SIM for "Calls and SMS" (to receive 2FA codes and urgent calls) and Cellesim for "Mobile Data". Warning: To avoid expensive roaming fees from your home carrier, ensure "Data Roaming" is turned OFF for your physical SIM.

Answer: Most Cellesim plans are data-only packages. This means they do not come with a local phone number for traditional calls or SMS.

The Solution: You can use your high-speed internet data to make voice and video calls via apps like WhatsApp, FaceTime, Messenger, Telegram, or Skype. Since these apps use the internet, you can stay connected with everyone without needing a standard phone number.

Answer: Absolutely not. At Cellesim, we believe in 100% transparency. You only pay the price you see on the screen. It is a one-time prepaid purchase with no contracts, no recurring subscriptions, and definitely no surprise roaming bills. 

Answer: Your plan's validity period (e.g., 7 days or 30 days) only begins when your eSIM connects to the local mobile network in your destination country.

The Benefit: This means you can safely purchase and install your eSIM weeks or even months before your trip. Your days will not start counting until you actually arrive and connect to the internet.

Answer: Our dedicated support team is available 24/7 to help you. If you encounter any connection problems, you can reach us immediately via Live Chat on our website or by email. We are here to ensure you get back online as quickly as possible. 

 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. 

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.
