Frequently Asked Questions

An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Instead of inserting a physical card, you simply scan a QR code we send to your email after purchase. Your device instantly connects to a local network at the destination — no waiting, no SIM swapping, no store visits.

NinjaSIM works with all eSIM-compatible devices including iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, and most modern iPads. Not sure? Go to Settings > Cellular (iPhone) or Settings > Network (Android) — if you see 'Add eSIM', you're good to go.

Absolutely. NinjaSIM runs alongside your existing SIM card. Your primary number stays active for calls and texts as normal, while NinjaSIM handles your data connection abroad. You get the best of both — no missed calls and no roaming charges.

We recommend installing your eSIM before your trip while on Wi-Fi, then activating it when you land. Your plan begins counting down from the moment it first connects to a network, so there's no need to activate weeks in advance.

If you use up your data allowance, simply visit ninjasim.com, purchase a new eSIM plan for your destination, and scan the new QR code. The process takes 90 seconds.

NinjaSIM connects you to local 4G/LTE and 5G networks (where available) in your destination country. Speeds are comparable to what locals experience — fast enough for video calls, streaming, navigation, and social media.

NinjaSIM plans are data-only. However, you can make calls and send messages using apps like WhatsApp, FaceTime, Telegram, or Skype over your data connection. Your primary SIM stays active for traditional calls and SMS.

You can check your data usage in your phone's Settings under Cellular/Mobile Data. Select your NinjaSIM plan to see how much data you've used. We also send notifications when you're running low.

We offer a full refund if your eSIM hasn't been activated yet. If you're experiencing issues after activation, contact our support team via WhatsApp or email and we'll resolve it — whether that's troubleshooting, a replacement, or a refund.
