Once you receive the aviz, fill out the technical authorization form, save it as a PDF, and sign it electronically.
You’ll then receive a payment invoice via MPay; make the payment and, as a courtesy, reply by email confirming the payment (you may attach proof of payment).
Then you’ll receive a form for the CEPT certificate – fill it out and send it.
You will receive the CEPT certificate and the technical authorization in electronic form.
Celebrate the result and continue enjoying the airwaves.
