Carriers and OEMs are working round the clock to make sure that 5G connectivity and devices that can support the standard will launch as early as possible. There were rumours painting the Galaxy S10 as the flagship that is not going to ship with a 5G modem, be it from Qualcomm’s X50 5G chip, or Samsung’s Exynos 5100 Modem and that is true, to an extent. According to new information, one variant of the Galaxy S10 might feature a 5G modem and thanks to all the rumours we have reported about so far, it appears that the Galaxy S10 Plus might be getting the special treatment in this department.

According to The Bell, 5G connectivity is still in its infancy right now, which only means that limited quantities of the Galaxy S10 Plus are going to be produced that will be touting a 5G modem. As per the info from the report, Samsung is expected to produce as low as two million units per year, until 5G connectivity gets widely adopted in the future.
