What is your question exactly? Do you want to know about your order?

Trying to get figure out why I can no longer connect to discord on my phone via Mobile data, since the plan change

Did you recently port from another carrier or you were an existing customer who changed the plan?

Do you have data enabled to your phone? also, which phone model are you using?

I'm an existing customer who changed plans. Yes data is enabled. Galaxy s9 

How about other apps? can they access your mobile data? I assumed you checked to see if you have data in the new plan.

Also, can you make sure you got the APN set correctly as per their instruction https://www.koodomobile.com/en/help/setting-data-your-non-koodo-phone

That is really strange. Have you tried to restart your phone?
