How can we help?

An eSIM (embedded SIM) is a digital SIM built into your device. It works exactly like a physical SIM card but can be activated instantly without swapping cards. You download an eSIM profile to your phone and connect to local networks at your destination.

Browse our destinations, choose a data plan that fits your trip, and complete the purchase. We accept all major payment methods. You'll receive your eSIM QR code via email within seconds of payment.

Most modern smartphones support eSIM, including iPhone 12 and newer, Samsung Galaxy S21 and newer, Google Pixel 6 and newer, and many other devices. Visit our compatibility page to check your specific device.

Yes. Modern phones support Dual SIM — your physical SIM card remains active for calls and texts while the eSIM handles cellular data. You don't need to remove anything.

After purchase, we send a QR code to your email. Open your phone camera, scan the code, and follow the on-screen prompts. The whole process takes under 60 seconds. See our detailed guide on the How It Works page.

Yes, and we recommend it. Install at home while you have WiFi. The eSIM remains inactive until you arrive at your destination and turn on data roaming.

Ensure good lighting and hold your phone steady 15–20cm from the code. If scanning fails, you can manually enter the activation code from the email. Go to Settings → Cellular → Add eSIM → Enter Details Manually.

No, each eSIM profile can only be installed on one device. Once installed, it is bound to that device. If you need to switch devices, contact our support team.

We accept all major credit and debit cards (Visa, Mastercard, American Express) as well as local payment methods through our payment provider. All transactions are processed securely with SSL encryption.

Yes. If your eSIM hasn't been activated (QR code not scanned), we offer a full refund. Contact our support team within 30 days of purchase and we'll process it immediately.

When your data is running low, you can purchase a top-up plan from MaxSim. The additional data is added to your existing eSIM — no reinstallation required. You'll receive a notification at 80% usage.

No. The price you see is the price you pay. No activation fees, no recurring costs, no auto-renewals. You buy a plan, you use it, and that's it.

Try these steps in order: (1) Ensure Data Roaming is ON for your eSIM line. (2) Toggle Airplane mode on and off. (3) Restart your phone. (4) Check that your eSIM is set as the data line in Settings. If issues persist after 5 minutes, contact our support.

Speed depends on local network conditions. Try: (1) Toggle Airplane mode. (2) Move to a location with better signal. (3) Check if you're connected to 4G/LTE (not 3G). In crowded areas, speeds may temporarily slow down — this is normal carrier behavior, not an eSIM issue.

Check your remaining data via your phone's data usage tracker: Settings → Cellular → your MaxSim line. You can also contact our support for an exact balance check.

Software updates very rarely affect eSIM profiles. If your eSIM isn't visible after an update, go to Settings → Cellular and check if it's listed but turned off. If it's completely gone, contact our support — we can help you reinstall it.
