I liked it. The travel eSIMs are super cheap. The app is simple, not overloaded, nice to look at. I planned a trip to Frankfurt in September, bought their prepaid eSIM (1GB for $3.99) and received a code for the next purchase. Quick activation upon arrival. I recommend it.

How it works

Install the TooSim app from the App Store (iOS 12.0+) or Google Play Store (Android) on an eSIM-compatible phone.

Open the app and create an account using your email address. Fill in your basic information.

Select the country or region where you are traveling. Browse available plans (regional or global) and choose the data volume and duration suited to your trip.

Confirm your order and pay using accepted methods (credit cards, PayPal, Apple Pay, Google Pay, etc.).

After payment, you instantly receive an activation QR code. No delivery wait!

Scan the QR code from the app or your phone’s settings. Follow instructions to install the eSIM profile. This step can be done before the trip.

Upon arrival at your destination, go to your phone’s network settings, select the TooSim eSIM, and enable data roaming. Your connection will start immediately.

⚠️ If it fails

✅ Make sure your phone supports eSIM and has a stable internet connection. Try scanning the code directly from network settings (Settings > Mobile Data > Add Plan). If the issue persists, contact [email protected] with a screenshot.

✅ Check that data roaming is enabled in settings. Ensure the TooSim eSIM is selected as the primary data network. Try restarting your phone and toggling airplane mode.

✅ Check your usage in the TooSim app. Disable automatic updates, high-resolution video playback, and background syncing. Identify heavy apps via your phone settings.

✅ TooSim offers refunds if the eSIM has not been used. Contact [email protected] or WhatsApp immediately with your order number. Processing times depend on your payment method.

FAQ

For a city trip or a week in Europe, choose the regional Europe plan with 5 to 10 GB of data depending on your usage (GPS, social networks, messaging). Plans of 7 to 14 days are best suited and start at $3.99 per GB. TooSim also offers 30-day plans if you stay longer.

Yes, absolutely! If your phone supports dual-SIM (physical + eSIM), you can keep your regular SIM active for calls/SMS and use the TooSim eSIM for data only. This setup is ideal to stay reachable on your usual number.

TooSim works on most recent eSIM-compatible smartphones: iPhone 11 and newer, Samsung Galaxy S21-S25, Google Pixel 6-7, OnePlus 9 Pro, Xiaomi Mi 11, Oppo Find X3 Pro, Sony Xperia 1 III, and others. Check the full list at toosim.com or your phone’s settings.

Your data plan only starts counting when the eSIM connects to a supported network in your destination country. You can install the eSIM before traveling without worry: data remains intact until your arrival.

No, TooSim plans are data only. However, you can use free apps like WhatsApp, FaceTime, Viber, or Skype to call and message. For calls to landlines, Viber and Skype offer very affordable rates.

Yes, TooSim guarantees a full refund if the eSIM has not been used or if the issue cannot be resolved by support. Contact [email protected] or WhatsApp promptly with your order number to initiate the refund.

Yes, tethering is possible with TooSim on most devices. You can share your eSIM connection with a computer or tablet. Note: this consumes data faster, so adjust your plan accordingly.

If you choose a regional plan (Europe, Asia, Middle East, etc.), you can use the same data across all countries in that region without extra charges. Otherwise, opt for the global plan that works everywhere. No need to buy an eSIM for each destination!
