DataSIM is a mobile app that lets you purchase and activate eSIM data plans for international travel. No physical SIM cards, no roaming charges — just instant connectivity wherever you go.
An eSIM is a digital SIM card embedded in your phone. It works like a physical SIM but can be activated instantly through a QR code or installation link.
Travelers, digital nomads, and remote workers who want reliable mobile data abroad without switching SIM cards.
Most recent iPhones, Google Pixels, and Samsung Galaxy devices support eSIM. However, your device must also be network unlocked and eSIM compatible. Please check your device settings under Mobile Network > SIM Manager or consult your phone’s official specifications.
After purchasing a plan, you will receive a QR code and/or installation link. Tap the link or scan the code to add the eSIM to your device.
Yes, many phones allow dual SIM functionality, so you can use your regular SIM for calls/SMS and your eSIM for data.
We offer eSIM data plans for over 70 countries, including the EU, USA, Canada, UAE, Turkey, Japan, and more. Plans are grouped by regions for flexibility.
Each plan is valid for 30 days starting immediately after purchase. Activation occurs instantly, so please purchase only when you're ready to use the data.
Yes, you can top up anytime through the app without reinstalling the eSIM.
You can pay securely using a credit or debit card via JCC online payment. Additional methods may be added in future updates.
All purchases are final and non-refundable, even if the eSIM is not used or installed. Please make sure your device is compatible before purchasing.
First, check mobile data settings and ensure roaming is enabled. If you still face issues, contact our support team via the app.
