3DS doesn't use NTSC or PAL. [...] That misunderstanding vindicates them for using region locking. They get away claiming it to be a format incompatibility instead of "if (Cartridge.Region != ThreeDS.Region) throw new FuckOffException();" which it is.
They also like to claim it's related to parental controls or piracy, which is just bullshit.
And to answer your question, it connects to the same internet, so no, there are no problems using a 3DS from a different region.
