Find quick answers about eSIM installation, plan purchases, payments, and troubleshooting.
Select your destination on the homepage, choose your data amount and validity period, complete payment, and receive a QR code confirmation email instantly. The whole process typically takes under 2 minutes.
After payment, a unique QR code is generated for your device. Go to Settings > Cellular (or Mobile Data) > Add eSIM and scan the code. Ensure you are connected to stable Wi-Fi during installation. Manual LPA activation code entry is also supported on most devices.
Your plan validity begins the first time you connect to a local network at your destination, not from the time of purchase or installation. Buy in advance without worrying about data being consumed early.
Major eSIM-compatible devices include iPhone XS / XR and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, iPad Pro (2018 and later), and more. Before purchasing, confirm the Add eSIM option is available in your device settings and that your device is unlocked.
Absolutely. Most eSIM-compatible devices support dual SIM mode: your physical SIM card continues to receive calls and texts while the CFJ-LINK eSIM handles data. They operate completely independently.
Each eSIM profile is bound to a single device. For multiple devices, please purchase separate plans. You can manage all your eSIM devices together within the app.
We accept Visa / Mastercard and other major credit and debit cards, digital wallets including Apple Pay and Google Pay, and multiple digital currencies. All transactions are protected by TLS 1.3 encryption.
Fiat payments are typically processed within 10 seconds. Digital currency payments vary slightly depending on network congestion but usually confirm within 1 minute. Your QR code is sent to your email and the app immediately upon confirmation.
Please check in order: 1. Confirm Data Roaming is enabled for the CFJ-LINK eSIM in your settings. 2. Verify APN settings match the instructions in your activation email. 3. Toggle Airplane Mode on for 10 seconds then off to force the device to re-register with local towers. 4. If the issue persists, restart your device.
Please ensure: 1. You are using your device's native camera or the system eSIM setup screen, not a third-party scanner app. 2. Your screen brightness is high enough. 3. Each QR code can only be used once. If your code has expired, please request a re-issue through the app or by contacting support.
Some devices allow eSIM profile re-download, but most carriers restrict each profile to a single activation for security reasons. If you accidentally deleted your eSIM, please contact our support team. We will verify and re-issue as appropriate.
Due to the irreversible cost of eSIM profile provisioning, active data plans are non-refundable as a general rule. If our platform causes a complete service failure, contact support within 48 hours to initiate a claim. Unactivated plans may be refunded in full before activation.
We recommend checking destination coverage on the plan page before purchasing. Coverage-related refund requests are evaluated on a case-by-case basis and a full refund cannot be guaranteed. If coverage is severely inadequate, please contact support to discuss solutions.
Our support team is available 24/7 and typically responds within 24 hours.
