Samsung Mobile has globally launched the next generation of their Samsung Gear smartwatch, the Samsung Galaxy Watch. The smartwatch integrates a consumer embedded SIM (eSIM) solution, exclusively supplied by G+D Mobile Security. This latest generation of Samsung smartwatches supports remote profile management over-the-air with mobile network operators (MNOs) in all regions. Consumers benefit from a user-friendly connectivity and seamless device management.

Many new connected devices or wearables, like the Samsung Galaxy Watch, do not have a slot for a pluggable SIM anymore but are instead capable of connecting to cellular networks via embedded SIM technology.

G+D Mobile Security supports a large number of MNOs worldwide in their eSIM projects. The cooperation between Samsung Mobile and G+D Mobile Security is long-standing, as the previous smartwatch generations Gear S2 and Gear S3 have also been using G+D’s technology.

"We are pleased that the proven G+D eSIM technology again met Samsung Mobile’s challenging quality and product requirements. This design-win is a further significant milestone in G+D Mobile Security’s consumer eSIM strategy, demonstrating our eSIM management market leadership,“ stated Carsten Ahrens, CEO of G+D Mobile Security. "It also is a testament to our strong relationship with Samsung as one of the global leading smartphone and wearable vendors.“

The eSIM solution implemented in the new Galaxy Watch model is based on G+D’s secure Sm@rtSIM CX platform and is compliant with current GSMA RSP v2.2 eSIM technical specifications for consumer devices.

The hardware integration uses an STMicroelectronics’ ST33G1M2 32-bit secure microcontroller in the smallest available form factor. The very tiny WLCSP (Wafer Level Chip Scale Package) microcontroller is optimised for the compact and stylish Galaxy Watch design.
