Getting my AW8 cel today and would really like to have cell enabled. currently I’m getting my plan through the company who buys it of a 3rd party but its with O2. When I asked the 3rd party supplier for the esim for my AW I was told this wasn’t possible despite O2 advertising with it.

Is there a way to still get cell and have it connected to my phone? If I IE take a different plan would whatsapp/apple music/health etc still be synced? How can i solve this?

I live in UK
