Dear Partners, We would like to inform you that, as part of our transition to a unified corporate identity under the Telekom brand, our corporate domain will be changed from OTE to Telekom. As a result, effective September 8, 2026, the following changes will apply: • The Portal access URL will change from: https://iot-portal.cosmote.gr/m2m-customer-portal/login to https://iot-portal.telekom.gr/m2m-customer-portal/login • Email addresses will change from: user@ote.gr to user@telekom.gr Please update your systems, contact lists, and any automated processes that use the above addresses. No action is required regarding user login credentials, which will remain unchanged. During a transition period, users accessing the old Portal URL will be automatically redirected to the new Portal, while emails sent to @ote.gr addresses will continue to be delivered normally. Should you require any clarification or assistance, please do not hesitate to contact us. Thank you for your cooperation. Telekom Team
