Hugo Marçal, Wholesale Business Unit Director at Go4Mobility, discusses the business messaging market and the opportunities for growth. He highlights that the A2P messaging market is far from reaching maturity and there are plenty of options to explore and expand the business. Go4Mobility provides interconnections between mobile operators and other aggregators for SMS and voice traffic. They also have a separate brand called Sendit that offers multi-channel marketing solutions to brands. Hugo mentions that in Portugal, SMS is still a key communication channel, especially for sensitive use cases like two-factor authentication in the banking and government sectors. He also talks about Go4Mobility's expansion into Portuguese-speaking African countries and the importance of providing reliable and high-quality traffic in those markets. Hugo emphasizes the need to protect against spam and fraud in the industry and the importance of building trust with customers. He advises newcomers to the business messaging industry to have a good understanding of technology and to develop strong relationship-building skills.
