The Ultra slim is a pocket-sized portable mobile router. Compared to the previous line, its 26% smaller and slimmer appearance fits the Ultra slim concept better. By removing ornamental things, we achieved a lighter design. Considering the user’s surroundings, a biscuit-shaped compact size leather pouch can protect it from external shock. Not only does it boast a slim shape, but it also features good functions. If a user has registered a public router, the Ultra slim switches to sleep mode automatically. Thus, it offers great usability in a smart way.
