This amazing KnowRoaming sticker looks too good to be true, but as it’s from Canada, it must be the real deal. The KnowRoaming is a sticker which covers your existing SIM card and automatically switches your iPhone to a local network provider when you travel abroad, avoiding crazy roaming fees when you travel.
The inner workings of the KnowRoaming “smart sticker” are not revealed on the site, but it seems like it works in concert with a companion app which lets you add funds to your KnowRoaming account, while co-opting whatever services your host SIM needs to provide to make it happen.
My suspicion is that the KnowRoaming sticker is little more than a fancy-looking SIM in slim sticker form, and works just like all other international SIMS you can buy, operating via carrier agreements, but I could be wrong: maybe this really does masquerade as a local SIM on a local network – but what then of activation.
Mysterious indeed, but also very useful for frequent travelers. Currently I’m using testing a rather excellent case that solves this problem by providing storage for several SIMs and a SIM removal tool, but auto beats manual every time I guess (except in cars).
The confusion is further compounded by the Kickstarter-style funding system, which offers all the delays and doubts of crowd-funding, with none of the security of a known service like Kickstarter.Related
