Frequent travelers who pre-ordered KnowRoaming's SIM stickers last year might finally be able to get their purchases as soon as next week. According to the company, it'll start sending out the first units to early adopters on February 5th, months after the original December shipping date. As its name implies, KnowRoaming's SIM sticker is a thin film that adheres to regular SIM cards. It can, in theory, automatically switch travelers' connections to local networks when they cross borders, thereby avoiding roaming charges. The firm hasn't revealed a retail availability yet, but at the rate things are going, it may be best not to hold your breath.
