When i try to switch to postpaid it doesnt work

The error message asked you to call the number. Have you tried to call it?

So im with koodo prepaid, have been for years, they text me, they email me, I get all these postpaid prompts when I sign in. But when I sign in I click one id like to change to and it doesnt work saying "Switching to Postpaid with an eSIM isn't available online yet. Visit a store or call 1-833-881-8878 and we'll get you set up"

Im not using an esim and never have, i have a physical Sim.

But the post paid plans are better, right now I get 10gb data 4G speed with unlimited calling paying $30 a month.

Its the postpaid plan worth it? Is 5G speed much faster?

I dont know my name is used when I signed up for koodo many years ago I can never verify myself lol

Eh, if there is a discrepancy in account naming, the rep might not be able to transfer it. If you would like to fix the name in the account, you could schedule a callback from a Koodo prepaid rep at www.koodo.com/prepaidchat

That isnt what my post is about, 

I think I jumped ahead of myself there. In the message from Koodo, the eSIM reference is for a postpaid plan - which allows you to use the plan right away. If you insist on a physical SIM, you would have to wait for the SIM card to be delivered by Canada Post. You can’t use a prepaid SIM for a postpaid plan.. And I was a little confused by the reference of the name in the prepaid account.

Regarding your question about 5G and a postpaid plan, postpaid plans have more features, like extra perks for international calling and Wi-Fi calling. 5G speed isn’t really needed if you are currently happy with Koodo.
