4. Common Issues and Quick Fixes

Even though the process is simple, first-time users may face small hiccups. Here are the most common issues when trying to install an eSIM and how to resolve them quickly:

QR Code Not Scanning

Increase your screen brightness.
Print the QR code for a clearer scan.
Ensure your camera lens is clean.

No Signal After Activation

Restart your phone.
Make sure the Twise eSIM is set as your primary data plan.
Check if roaming is enabled (for travel eSIMs).

Activation Failed

Twise Travel Tips

Here’s a pro tip many travelers wish they knew earlier: always install your eSIM before you leave for the airport.
Why?
Because once you depart, you may not have stable Wi-Fi to scan your QR code or download your eSIM profile. Travelers often learn this the hard way — arriving in another country with no internet to complete activation.

Install your eSIM in advance and travel with confidence. Twise offers fast, reliable data plans for every destination — from single-country options to regional and global eSIMs.
