Do O2 SIMs use the S@T Browser / Toolkit

Marie_S · ‎16-09-2019

There have been reports of a new sim-card based vulnerability that exploits simcards that have the S@T Browser / Toolkit built into them. Does anyone at O2 know if their SIM cards use it and so if we are affected by this vulnerability?

Sounds like one for @Chris_K ?

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.

Hi @Marie_S - to help reassure you a little on this, I can confirm no O2 SIMs (including Tesco Mobile and giffgaff) have the S@T Browser application built into them.

PS. Thanks for the tag @MI5
