> Small brands capitalized on the market’s transition from 2G to 3G/4G, benefitting from strong entry-tier demand, particularly in Africa, Asia and Latin America.
It's normal for companies to use different names to operate in different markets. There's some bidirectional setting of value through exclusivity that happens in some cases as well, like with Nismo. It's not exclusively an American concept.
I always found it interesting that in other countries, they trade under "National"-- an even more perfectly English sounding word. I have a radio that I suspect originally game from the German market with a "National Panasonic" badge, because I guess they couldn't quite decide what brand to use.
Who are they catering to? 99% of these companies are reselling the same crap you see on Aliexpress, so I can't imagine they bother to use the same branding domestically
