First, make sure that your device can work with eSIM technology and that it can be used with other companies by unlocking it.
Make sure the software on your device is up-to-date, since old software can make it hard to activate your eSIM.
Also, make sure your device is linked to a stable Wi-Fi network while the activation process is going on. A good internet connection is very important.
If the problem with activation keeps happening, MobiMatter has a workaround tool that can help at any time.
Go to https://mobimatter.com/tr/troubleshoot to get to it. Follow the steps shown on the screen to find the problem and, hopefully, fix it.
Visit MobiMatter's Help Desk (https://help.mobimatter.com/hc/en-us/requests/new) to ask for direct help.
You can also email them at [email protected].
If the problem is still not fixed, you might want to file a report on Xolvie to let other people know about it.
