Galaxy watch error code

[cwmparc]

Anyone having the error code 2003 while trying to set up the data plan.

Have spoken to EE, who have said it's a known issue. Wondering if any other network is affected

similar issue, I just made a post - I do not see an "error code" as you do but when not near my phone I have no data!  I am paying $10/mo to t-mobile to have data plan just for my watch.  My Active 2 44mm never had this issue!  Upgraded and wow - no data when not by phone.  SMH!  T-Mobile ran all their tests, no issues on their end 😞

I switched from another provider where my Watch 5 Pro LTE's ESim was activated.

I have a new provider that supports watch plans and numbershare, but it doesn't work for me.  I've spent hours at the boutique, submitted a ticket and still can't get a watch plan to activate when trying from the phone, or the watch.

I get an error window saying that my provider does not support watch plan and an error code: -1

(and contact Samsung CS...)

Yes, I have the latest updates across the board.  Tried a watch reset and reinstalled the phone Galaxy Wear app.  Phone is One+9 5g.
