How to get visual voicemail activated on iphone 13 after upgrading?

Hello I have a dilemma.

I recently purchased an iphone 13 from iphone 6 and swapped out the sim card.

Voicemail was not enabled on my phone/sim card so I enabled it which was a whole ordeal in itself. And sent a couple of test voicemails. Which I was able to play but the visual voicemail feature does not seem  to be there.

I then follow the dozens of other articles people have with similar issues. From reset network settings to clock settings to siri settings. None seemed to allow me to see visual voicemails.

I tried contacting cricket wireless support twice now and they were wholly unsuccessful in getting my issue resolved.And the representative at the store couldn’t help.

It also doesn’t help matters that the feature is baked in so I have no clear confirmation about the issue other than to soft-test it.

Please someone tell me how to enable this seemingly basic feature on my phone.
