Asia (20 Countries) eSIM

Answer: Our Asia Regional Plan connects you in 20 destinations with a single eSIM. It covers the entire Far East (Japan, South Korea, China), Southeast Asia (Thailand, Singapore, Vietnam, Indonesia/Bali), and even extends to Australia, New Zealand, and Saudi Arabia. 

Answer: Yes. We provide strong 4G/LTE connectivity on popular holiday islands like Bali, Phuket, Koh Samui, Cebu, and Boracay. Note: Coverage is stable in hotels and town centers. However, signal strength may fluctuate during boat trips between islands or in very remote, uninhabited bays. 

Answer: No, the switch is automatic and seamless. When you cross the border during your Asia tour, your phone connects to the new country's local carrier without you needing to do anything. Just make sure your "Data Roaming" is turned ON. 

Answer: Yes! Thanks to Cellesim eSIM technology, your connection bypasses China's internet restrictions (Great Firewall). You can freely use blocked apps like Google Maps, Instagram, Facebook, and WhatsApp without needing an extra VPN app. 

Planning the trip? See our China eSIM plans, install in one tap before you fly, and land online. Free VPN included.

Answer: Absolutely! You can smoothly use essential local apps like Grab/Gojek (for taxis and food) and Line/WeChat/KakaoTalk (for messaging) with your Cellesim internet connection throughout your Asia trip. 

Answer: No, absolutely not. Your Cellesim Asia eSIM provides data only, so it does not change your phone number. You can keep using WhatsApp, Line, WeChat, or KakaoTalk with your original number.

Important: If an app asks "Do you want to update to the new number?", simply select "Keep My Number".

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

Answer: Don't worry. You don't need to hunt for Wi-Fi to top up. You can easily purchase additional data (Top-up) for your existing eSIM via the "My eSIMs" section on our website before your current plan runs out completely. 

Look up your phone’s exact model number with the manufacturer to see if it’s listed as compatible, and make sure your phone is not carrier-locked. Seeing an EID number or an “Add eSIM” option in your settings is a good sign, but some phones have regional restrictions. If you’re not sure, please contact our support team before you buy.
