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. 

No! This is the single biggest advantage of our eSIM. Due to Bangladesh's strict laws, buying a physical local SIM card at Dhaka (DAC) airport requires a mandatory, slow, and complicated biometric (fingerprint) and passport registration process. Cellesim eSIMs are roaming-based, which means you are exempt from all this bureaucracy. You can buy online, install instantly, and skip the registration queues. 

Yes, absolutely. Uber and Pathao (for rickshaws/cars) are essential apps for navigating the chaotic traffic of Dhaka. Our eSIM provides fast, low-latency 4G data, which is crucial for ordering a ride from the airport, tracking your driver in real-time, and using Google Maps without lag. 

It varies. You will have excellent 4G/LTE coverage in all major cities (Dhaka, Chittagong) and divisional towns. You will also have a good signal in popular tourist areas like Srimangal (tea gardens). However, in extremely remote areas like the Sundarbans (jungle) or the Chittagong Hill Tracts, you must expect the signal to be intermittent (3G) or non-existent. 

No, absolutely not. Bangladesh is NOT part of the EU, UK, or US domestic plans. Most home carriers (like AT&T, Verizon, T-Mobile, or UK's Vodafone/O2) will charge you their highest "Rest of World" international roaming rates (e.g., $10-$15 per day). A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper. 

 To give you the best speed and coverage, our eSIM connects to Bangladesh’s premium Tier-1 networks, typically Grameenphone (GP) or Robi/Airtel. Grameenphone is widely regarded as the #1 provider with the fastest speeds and the most extensive 4G coverage, ensuring you stay connected not just in Dhaka but also in cities like Chittagong and Sylhet.
