FAQ
Frequently Asked Questions about your trevvel eSIM
Everything you need to know before you take off.
📲 How do I install the trevvel eSIM?
After your purchase, you will receive an email with a link. There, you can install the eSIM either via QR code or – if you use an iPhone – add it directly via the Quickinstall button.
🇩🇪 Should I activate the eSIM in Germany?
Yes, ideally you should install the eSIM before your trip in Germany. Alternatively, you can also activate it abroad – but you will need a stable Wi-Fi connection for this.
📡 What do I need to do after installation?
Please activate data roaming for the eSIM profile. Only then will you be able to use the mobile connection abroad.
🧳 Which eSIM should use data abroad?
After landing in your destination country, you need to activate the eSIM as your primary data connection in your device settings. You can find this setting under Settings > Mobile Data > Mobile Data.
💡 What are the advantages of a trevvel eSIM?
✔ No more expensive roaming
✔ Ready to use – worldwide
✔ No annoying SIM card change
✔ Support via WhatsApp
✔ Activate eSIM easily before your trip
🔁 Can I top up my data volume later?
Currently, it is not possible to purchase additional data. However, you can always buy and install a new eSIM once your data volume is used up.
📊 How do I see how much data volume I still have?
Simply use the link from your order confirmation email – there you can always view your remaining balance and manage the eSIM.
📧 Can I buy multiple eSIMs at once?
Technically yes – but we recommend buying only one eSIM per order. This avoids potential shipping or activation issues.
⚠️ I'm getting an error message during installation. What should I do?
Some iPhones display that the eSIM could not be installed. Important: Go to your settings under Mobile Data – usually the eSIM has already been added and can be activated there.
🌍 Do I have to remove my own SIM card?
No. Your normal SIM remains active. The eSIM runs in parallel and can be activated separately for mobile data.
📱 Does trevvel work with every smartphone?
Your smartphone must be eSIM-compatible. Most newer iPhones (from XS), Samsung Galaxy (from S20), Google Pixel (from 3) and many Huawei models support eSIMs.
