Hi ​@Miroeslaw,

Thanks for your post.

Unfortunately, iD Mobile SIM cards and eSIMs aren't supported in smart watches, including LTE-enabled models such as the Galaxy Watch Ultra.

This means it's not possible to add your iD Mobile eSIM to the watch and use your minutes, texts and data independently of your phone in the same way that some other networks offer through smartwatch plans. I'm sorry for any disappointment or inconvenience this may cause.

As things stand, your Galaxy Watch would need to be connected to your phone via Bluetooth (or Wi-Fi where available) to access calls, messages and data through your mobile service.

For customers looking to use a smartwatch primarily for fitness tracking, notifications and general smart features, we would typically recommend the GPS/Bluetooth functionality rather than the cellular capability.

If support for cellular smartwatches becomes available in the future, any updates will be communicated on our website and Community.

I hope this clarifies things.

Regards,
