The upcoming rollout of 5G cellular networks (2020) is expected to be a huge leap forward in the way we use connected devices. Its projected that 5G will allow for individual download speeds of 1 Gigabit per second, with latency speeds of less than a millisecond. According to Gartner, an estimated 20.8 billion internet-enabled devices will be in service worldwide by 2020, many of which will utilize the 5G network. To handle all that speed and connectivity, companies are expected to invest upwards of $275 billion into revamped infrastructure within the next decade, according to a report published by Accenture.
The imminent 5G revolution will present a significant update to SIM technology. Since 2012, the nano-SIM card has been more than capable of processing information coming through the Global System for Mobile Communications (GSM). With the coming of 5G and the expansion of cellular-enabled devices through the Internet of Things (IoT), SIM cards are becoming smaller and more agile.
Making Full Use of 5G Networks with Embedded SIMs
The 5G future of SIM cards lies in embedded SIMs, or eSIM. Unlike traditional SIM cards that can be removed and replaced in new devices, eSIM cards are integrated permanently into a device. Smaller than standard nano-SIMs, they can fit into wearables, such as smartwatches and fitness bands. They are rewritable, compliant with all operators, and can be activated and managed remotely using remote SIM provisioning (over-the-air updates).
Embedded SIMs still play the same integral role in 5G networks that their nano-, micro-, mini-, and full-size forebears have by identifying and connecting devices to the GSM. But a fully-integrated 5G-capable eSIM offers a versatility we havent seen before in SIM technology. A device owner will be able to switch cellular carriers without having to switch SIMs or visit a provider. When traveling abroad, eSIMs will use international GSMs seamlessly.
For businesses that use the GSM to stay connected, the eSIM will help them manage their networked assets wherever they are in the world, and with more agility than previous SIM cards. For those hoping to get the most out of 5G through the use of an integrated IoT solution, eSIMs already are being placed in a host of new cellular-enabled devices, such as automotive telematics systems and wearables. When 5G becomes standard, these devices will possess processing power that is incredibly robust, and will rely on their fully integrated eSIMs to manage their connection.
