Telecommunication carriers plan to expand their infrastructure that will allow for the use of higher speeds of download and upload during using the mobile Internet, but the infrastructure itself is not everything. To use the full speed that 5G offers, you also need a phone that supports this type of network, and it seems that MWC 2019 will be an event during which we will get to know many smartphones that will be created especially to support 5G connectivity.
Based on the latest reports, we can expect that Samsung will present a new line of devices at MWC 2019. If the information will be confirmed, then surely new Samsung's series will support the 5G network, but we do not know how will look situation with flagship series named Galaxy S. In addition, journalists inform also about improved version of LG G7 ThinQ, which would be given the name LG G7+ ThinQ 5G, and the main change would be obviously support for 5G network service.
