To find out if you are registered with idCAT Mòbil, you can try identifying yourself on the website of a public administration or on the e-TRAM test website (the procedures carried out have no legal validity).
In this sense, access the Generic Instance from the "Start" button and provide your identification document and telephone number:

If you see the following error message "There seems to be a problem with the identification document and/or phone number you provided" it could be:
1. If you are not registered with idCAT Mobile, see how to register online with idCAT Mobile.
2. You are indicating a space between your identification document number and the letter or between the numbers of your phone. Check it, remove them and try again.
3. You have changed your telephone number, therefore, you will have to modify your idCAT Mòbil data.

However, if you see the following message: "A text message with the password has been sent to your mobile phone" you will receive an SMS, enter it to authenticate yourself and press "Verify":

If you have been able to correctly access the Generic Instance procedure , as shown below, it means that you have registered your idCAT Mobile with the data indicated and you can now use your idCAT Mobile.
