Sender Alpha-Name or alphanumeric ID is aimed to qualify you as an addressee. It is the first thing a subscriber sees, a key decision-impacting factor. Sender Name increases awareness and proves authenticity. Certain countries require its registration and some even impose carrier filtering. Check your message's destination countries, and submit a registration ticket in your account. Any combination of alphanumeric characters will do, like a brand name or something congruous. Never send messages on behalf of someone else’s company.
