UK ISP Tests SIM Card That Forces All of Your Mobile Data Through Tor

An anonymous reader quotes a report from Motherboard: [O]ne UK grassroots internet service provider is currently testing a data only SIM card that blocks any non-Tor traffic from leaving the phone at all, potentially providing a more robust way to use Tor while on the go. 'This is about sticking a middle finger up to mobile filtering, mass surveillance,' Gareth Llewelyn, founder of Brass Horn Communications, told Motherboard in an online chat. Brass Horn is a non-profit internet service provider with a focus on privacy and anti-surveillance services. Tor is a piece of software and a related network run by volunteers. When someone runs Tor on their computer or phone, it routes their traffic through multiple servers before reaching its final destination, such as a website. That way, the website owner can't tell who is visiting; only that someone is connecting from Tor. The most common way people access Tor is with the Tor Browser Bundle on desktop, or with the Orbot app on Android.

But, in some cases, neither of these totally guarantee that all of your device's traffic will be routed through Tor. If you're using the Tor Browser Bundle on a laptop, and then go to use another piece of software, that app is probably not going to use Tor. The same might stand for Orbot running on older iterations of Android. Nathan Freitas, from The Guardian Project which maintains Orbot, said with newer versions of Android, you can lock down device traffic to only work if a specific VPN is activated, including Orbot's. This SIM card, however, is supposed to provide a more restricted solution in the event that other approaches don't quite work. The UK-exclusive SIM card requires that users create a new access point name on their device. It also requires Orbot to be installed and running on the device itself.
