You may get an error message if the QR code hasn’t been scanned properly or the eSIM isn’t installed right. QR codes can be partially scanned due to a bad connection or lighting. If you want to check if your eSIM is installed properly, then you should look in the device settings of your phone.
If you have any questions, please do not hesitate to contact our Telitravel Support Team. We are here and happy to help!
