Can I add an Esim device to a phone contract?

[Popuptoaster]

Hi, I am thinking about migrating across to O2 from 3, I am specifically interested in the 100GB 24 month airtime sim only plan.

I have a Tickwatch 3 pro Esim smartwatch that runs Gear OS 3 and would like to know if I can add it to the phone contract, sharing the same number and allowances.

I am not interested in connecting via Bluetooth as there are situations where I have to leave the phone locked in a vehicle and go miles away, relying on the watch to receive messages, deal with calls and emails etc.

I am also not interested in swapping to Apple or Samung products so if these are the only options I'll have to look elsewhere.

Thanks for any help.

No sorry.

That device is not supported by O2.

OK, thanks for your input, looking like Vodaphone is my only choice and i was trying to avoid them. :S
