2G/3G Sunset: How to Future-Proof Your IoT Fleet

The introduction of 5G with 6G already being discussed means that older networks like 2G and 3G are being phased out, leaving IoT devices scrambling to upgrade their equipment. To future-proof your IoT fleet, consider upgrading your devices' IoT SIM cards to a Multi-IMSI architecture and eSIM hardware at the same time. This will help you navigate the fragmented landscape of cellular innovation and minimize the need for physical SIM swaps in the future. The main advantages of 5G are ultra-low latency and high bandwidth, but for most IoT use cases, these are not needed, making a bet on a 4G-LTE modem a safe bet for any IoT device builder today. eSIMs can hold multiple SIM profiles at once, eliminating the need to physically swap SIMs, but true independence comes with Consumer Profiles that have switching code either on the SIM itself or the device, and Multi-IMSI SIM profiles are ideal for larger global deployments, providing access to dozens or hundreds of networks with a single SIM profile.
