A 5G SIM card is a tamper-proof security element that secures 5G network access and addresses key 5G attributes[1]. The benefits of using a 5G SIM include optimized roaming, smart 5G slice access, and enhanced security and privacy[1][9].
Key advantages:
* Seamless 5G Roaming Experience A 5G SIM ensures mobile operators can offer users a seamless and optimal 5G roaming experience while maximizing their roaming revenues, thanks to 5G SIM-based over-the-air 5G steering of roaming capabilities[1].
* Smart 5G Slice Access A 5G SIM card ensures the user device is configured to use the most adequate network slice depending on data usage expectation to guarantee the best quality of services in terms of debit and latency, such as for gaming, streaming, and augmented reality[1].
* Enhanced Security and Privacy The 5G SIM incorporates advanced features to promote the highest levels of security and user privacy[9]. It is the only platform that can be used to secure 5G network access[6][9].
* Optimized Roaming Experience The list of optimized local mobile networks is directly sent to User Equipment by the home MNO through OTA with an utmost success rate[1]. An unfairly visited network can no more intercept/modify the roaming business rules sent by the home network to the end user's SIM card when he is detected roaming abroad[1].
* Public/Private Network Handover The private network credentials are stored in the USIM to guarantee highly secured access. SIM based application dynamically switches from Public to Private network and vice versa[1].
* Post-issuance SIM operating system upgradability The 5G SIM operating system is upgradable post-issuance over the air like other smart connected objects. It allows a consistent and up-to-date SIM deployed fleet in terms of cybersecurity and functionalities[1].
* Plug & Play User Experience When the end user inserts their new 5G SIM in their new 5G phone for the first time, no configuration is needed since all the 5G networks settings are provided by the 5G SIM. It eases the end user's first experience and reduces the cost of support for the mobile network operator[1].
* Advanced mobile broadband experience Faster speeds and lower latency provide a significantly improved mobile broadband experience, including seamless video calls, high-quality playback and video streaming, faster web browsing and app downloads, and improved performance for data-heavy apps[3].
