Cannot switch plans

[chesslearner]

I'm currently on THE NEW VERIZON PLAN LARGE 8GB. I'm interested to switching all 4 lines to the $35 Unlimited Plan because I want free Disney+. But every time I try to change my plan, I get the error below. Any ideas? TY

I'm sorry you were having problems switching plans and we would love to see you get the Disney Plus promotion. Where are you seeing this error? Are you trying to change on a web page or using the app? Try changing your plan using this link: https://m.vzw.com/m/huQP

Steps to reproduce this error:

1. My Verizon - Overview https://myvpostpay.verizonwireless.com/ui/hub/secure/overview?flow=1D#/

2. Plan -> Manage Plan https://www.verizonwireless.com/digital/ui/cpc/secure/#/

3. Explore Plans https://www.verizonwireless.com/digital/ui/cpc/secure/#/selectPlans

4. Continue https://www.verizonwireless.com/digital/ui/cpc/secure/#/ExploreMMPlan

The link provided also leads to the same error in step 4.

App also throws error when attempting to change plans.

Thank you

Thanks for the steps that you're taking to try to make the plan change, Chesslearner. I'd love to take a closer look at the details of the account with you. I've sent you a Private Note. Please response back to that note. KevinR_VZW

After authentication, I'm informed:

Perfect! I do apologize but at this time to make any changes to your account you will need to call, 888-483-7200. They will be able to assist you with your plan change.

This does nothing to fix the error message that I have detailed. I don't want to make any changes until I can explore plans on the website.
