Esim activation not working on iphone 11 pro

Hey there,

See ☞ If Dual SIM with an eSIM isn't working on your iPhone

"Check your plans

• Your iPhone must be unlocked, or both cellular plans must be from the same carrier.
• Both plans must be set up and ready to use.
• Your carrier or carriers must support Dual SIM with an eSIM.
• If a CDMA carrier provides your first SIM, your second SIM won't support CDMA. Contact your carrier for more information."

If everything checks out there, see if this helps:

"If you can't set up your eSIM

• Check with your carrier to see if your iPhone plan is eligible for Dual SIM service.
• If you have an enterprise or corporate cellular service plan, check with your company or carrier to see if they support this feature. 
• Make sure that your carriers support coverage in your area and that there are no service outages.
• Make sure that your cellular plans are set up, ready to use, and don’t have a billing-related blockage.

If you still can't set up your eSIM, contact your carriers for support."
