Now one can chat on International Calls in Local Call rates, by using a sticker.
This costs $35.
“It’s not hard to spend more on international roaming charges abroad than you did on the ticket there, but cloak your cell’s SIM card with a KnowRoaming sticker ($35) and you could be chatting andSnapchatting your heart out while only shelling out for local service. How? It recognizes when you’ve left your coverage area, and rather than switch to roaming, it seamlessly routes you through a local provider. They, in turn, get compensated for your talk and data usage via a prepaid account (which you manage via a dedicated app). And you won’t be need to use alias digits, either, since calls to your regular number are automatically forwarded.

The Gossamer is a small portable device that can be used to secretly gather data on mobile phones operating in a target area. It sends out a covert signal that tricks phones into handing over their unique codes—such as the IMSI and TMSI—which can be used to identify users and home in on specific devices of interest. What makes it different from the Stingray? Not only is the Gossamer much smaller, but it can also be used to perform a denial-of-service attack on phone users, blocking targeted people from making or receiving calls, according tomarketing materials (PDF) published by a Brazilian reseller of the Harris equipment. The Gossamer has the appearance of a clunky-looking handheld transceiver. One photograph filed with the US Patent and Trademark Office shows it displaying an option for “mobile interrogation” on its small LCD screen, which sits above a telephone-style keypad.
First used: Trademark records show that a registration for the Gossamer was first filed in October 2001.
