Once you have all the required documents completed, you may proceed to Port Rashid and meet Etisalat's personnel there, who will guide you on certificate enrollment process. If you have a USB memory stick, they will store your certificates on it. Otherwise, they will send it to you through email.
Note: The certificate requests for Mersal 2 are processed at Port Rashid only, not at any of Etisalat's business centres. You need to come personally there, faxing or emailing the documents are not accepted.
