Samsung is definitely launching a foldable smartphone next year, but that doesn't mean it will be available for purchase worldwide. Dubbed Samsung Galaxy X, the upcoming foldable smartphone was previously listed on the company's support site with model number SM-G888N0, or at least that's what we thought.

Unfortunately, Samsung SM-G888N0 is not the highly-anticipated Galaxy X foldable smartphone, but a rugged phone for professionals. Samsung issued a press release a few days ago that highlights the importance of next-generation technology for smart train and metro, which is supposed to enable high-speed communications in South Korea.

One of the devices that supports the new LTE-R next-generation communications technology is the Samsung SM-G888N0 rugged smartphone, the South Korean company confirmed in the press release.

There aren't any other details about the SM-G888N0, but now that we know it's just a rugged smartphone for professionals, it should be a little importance. Also, it's only available in South Korea, at least for the time being.
