BARCELONA - Chinese small- and medium-sized enterprises (SMEs) have managed to show up at the Mobile World Congress (MWC) fair by using digital technologies.

Unlike the big companies that have large booths at the MWC -- the most important event of the mobile phone industry being held here, smaller companies often lack the resources to do so.

Digital technologies are bringing opportunities for them, and enabling them, as smaller companies, to be integrated into the global industry and make transactions easier with lower costs.

While some don't have a physical store, online platforms enable them to directly connect with overseas buyers.

DHgate.com is one example. This online platform helps Chinese SMEs to connect with overseas buyers.

Hang Li, overseas marketing manager at DHGate.com, told Xinhua that they worked as a bridge of Chinese products to the world, offering high-tech products from China at the client's fingertips.

The platform provides a massive selection of quality and price competitive products. It has 1.4 million sellers globally, 10 million buyers worldwide and 40 million product listings online.

Products range from drones to virtual reality glasses, waterproof sports cameras with ICT resolution and other smart wearable items, such as wireless earbuds that allow users to listen to music and talk on their phones.

This year's MWC, to be closed on Thursday, gathers leading companies of the mobile phone industry to showcase their devices and cutting-edge technology.

The event is expected to receive a total of 101,000 industry professionals, over 160 government delegations, 4,000 representatives and 2,200 exhibitors.
