Can I add an eSIM to an existing plan

[ADN]

I already have a SIM card in an iPhone but want to add an eSIM on to the plan for use in an iPad using the same plan. Is that possible?

You can add another dataplan (at monthly cost) to your account - either SIM or eSIM.

You cannot 'share' any existing dataplan.

(That's what the piggybank is for)

You could always tether your iPad to your phone to use the plan...  (Set up a personal hotspot)
