KONTACT SIM
FREEDOM FROM THIRD-PARTY SERVICE PROVIDERS
When using an encrypted mobile device, the security of the data and communications are directly dependent on the mobile service provider or network carrier. Mobile service providers and/or network carriers can access all unencrypted data passing through it.
Additionally, through the mobile network and SIM card, mobile operators can push over-the-air (OTA) updates.
The OTA flow presents a serious threat as it can push any software to the device in the background with escalated privileges, regardless of any defense mechanisms the device might have. This technical flow could easily be abused by ill-intenders with access to the mobile network to collect sensitive data.

GLOBAL COVERAGE
GLOBAL ROAMING INCLUSIVE
Since various regions and local operators operate on different bandwidths and IMSI numbers, it can be quite challenging to achieve near-perfect global connectivity at a low cost.
The specifications of the multi-IMSI SIM card allow it to store multiple IMSI numbers and switch between them.
This mechanism allows the KONTACT SIM card to not only connect to numerous local carriers globally but also guarantees near-perfect connectivity.
The multi-IMSI SIM card always connects to the local operator with the best coverage and signal quality, ensuring optimal connectivity in more than 180 countries.
Intense network usage beyond regional borders is usually quite costly.
Allowing all users to communicate cross-borders could require a significant investment.
KONTACT is subscription-based without extra fees for roaming or data usage globally. This structure allows for greater expense predictability, planning capacity, and cost control.

ANONYMITY
The identity of a KONTACT user is anonymous.
The operator can only see a general user in their network while connected to it.
Communications remain completely private and secure.

SS7 & DIAMETER FIREWALL
Generally speaking, SS7 is a set of protocols that connects one mobile device network to another.
Mobile operators use it for passing messages and calls between various mobile networks while ensuring correct billing.
SS7 allows users of one network to roam on another when changing geolocation, to guarantee constant connectivity.
However, hackers can easily penetrate the SS7 system and gain escalated privileges, capable of accessing sensitive information on the device, such as calls, messages, and even physical location.
Signaling attacks include man-in-the-middle, location tracking, denial of service (DoS), and more. KONTACT’s SIM solution features a built-in Smart SS7 and Diameter firewall, providing multi-layered protection against signaling attacks.
Hardened SIM Took Kit (STK)
Our security-hardened STK, combined with a silent SMS firewall prevents the most sophisticated SMS-based attacks, including Simjacker, and more.

BUILT-IN VPN
When using our SIM card to connect to a 2G, 3G, or 4G network, all traffic is always protected by VPN.
This means all communication transmitted goes through an encrypted tunnel before delivery to the recipient.
Separately, the KONTACT app has end-to-end encryption for chats, files, and calls.
Our built-in SIM VPN is one of many additional layers of security.
