Mobile World Congress (MWC) 2018 has seen dozens of 5G-related announcements, spanning devices, modems, radios, plans, spectrum, and trials.

Pictures of Samsung's latest flagship phone have been disclosed by an app released by the firm itself. The images were discovered hidden via a hack of Unpacked 2018, a program that the company has asked invitees to Sunday's launch of the handset in Barcelona to download.

Many of the devices to be unveiled at MWC 2018 will head to India and have a tangible impact on the market there.

Vodafone and Huawei have jointly completed the world's first call using the non stand-alone (NSA) 3GPP 5G new radio (NR) standard and sub6 GHz spectrum. The call, using a test network, took place in Spain just ahead of Mobile World Congress which starts on February 26.

Sony is also confirmed to be hosting its keynote on February 26, and chances are that the company will announce the Xperia XZ and Xperia XZ Pro flagship handsets during that press conference.
