Network Transfer is Cumbersome

I signed up for US mobile Premium Unlimited Annual plan because I was under the impression that network transfers would be fairly quick and easy since I travel regularlyx

However, this has been far from the truth. Whenever I initiated a transfer from WARP to Light Speed, I lose my Apple Watch plan too.

When I try to switch back from Light Speed to Warp, I have to manually contact customer service, go through 30 - 60 min of chatting with a rep to reactivate my Apple Watch plan.

Does USM have plans to make these network transfers more seamless such that when I do transfer back to Warp, my Apple Watch plan is automatically updated too?
