The short answer is yes. Device manufacturers may not need to provide the connectivity, but they need to ensure their devices can connect to available networks.
4G is widely available and 5G is being rolled out by all major mobile operators. Roaming options are available globally. WiFi and Bluetooth are useful for short-range, high-bandwidth communications, however 4G and 5G allow IoT devices to connect to mobile towers much further away. 4G is a cost-effective, reliable service, used by many IoT devices globally.
eSIMs can be embedded into devices or delivered as a traditional plastic SIM. Operator profiles on the eUICC can be securely and remotely updated over-the-air. Instead of swapping plastic SIM cards, profiles are downloaded and managed on a device as needed. In the eSIM model, a device is ready to deploy anywhere network coverage exists. If a device moves and crosses networks, its profile can be updated quickly and securely.
Global IoT manufacturers and distributors have been considering how to scale the Internet of Things and increase adoption. Scale is both the biggest opportunity and biggest challenge, as the cost of changing SIMs in millions of devices can be prohibitively expensive. eSIMs resolve this.
