Can you test this by putting in a non-koodo sim to see if another sim fixes the issue?

Already tested and this is a Koodo issue. Also see the Reddit link as others have tried that as well.

I recommend reporting the outage.  THis is the best way to get on their radar if multiple people report this outage

I updated my devices to ios 18.1 with Koodo. RCS worked just fine.

After the update, The iPhone showed up a message to update “carrier update” profile. Have you accepted to update it?

Same problem here. Iphone 15 Pro Max, purchased from Apple, updated to IOS 18.1 this morning and the ability to use RCS in Messages is gone and the RCS toggle in the settings is gone. The carrier profile was automatically updated with the IOS update - no user interaction needed. Koodo carrier version 60.1 

This problem is specific to Koodo and does not affect Telus users.

I spoke too early. As I am using a dual SIM, the iphone automatically switched to another carrier for RCS.

The current Koodo carrier profile 60.1 didn’t include RCS, it appears.

I will flag a rep to have more information on it

Same issue for me.  No way of contacting Koodo support about this because all you can do is schedule a call back.  No availability for days.  An absolute joke.  Headed to Rogers tonight to switch because I can’t stand the fact that Koodo has no support phone number to call.  

Same issue here. No RCS at all. Super frustrating because I recently got rid of WhatsApp because I didn’t see the point of having it anymore with RCS being a thing. If Koodo doesn’t fix this soon they’ll loose me as a customer.
