Nothing a3 pro

The thing to check isn't really a Koodo list, it's VoLTE. The national 3G shutdown starts March 1st 2027, and after that a device needs VoLTE to keep voice and text working. Is yours a Canadian model or an imported one? Nothing phones aren't sold through Koodo and I haven't seen many reports of people using them here. With devices not sold in Canada you can end up with data working fine but no VoLTE or wifi calling, same as what happened with the OnePlus 12. Worth checking the specs against

The IMEI tool isn't always correct btw.

Well, I bought my phone in Canada (swiftronics) but it is an imported phone. It does not have Volte so I guess I need to find a new phone by march 1st. Very disappointing. This phone is usable anywhere in the world except Canada. How all these providers have got together and grey listed these imported phones smacks of price fixing. Very poor. 

According to this comment, the Nothing 4a Pro is not compatible on Public Mobile and is mainly relying on the 3G network. This would apply to your device on the Koodo network as well.

On the contrary, the global version of the latest OnePlus devices seem to be compatible with VoLTE on the Koodo network, as evidenced by this post. From what I know, the VoLTE feature works from OnePlus 10 onwards. As a precautionary measure, you can consider getting the OnePlus 13 or a later model as an option. 

If you are able to return the device, I would suggest you to do it as soon as possible. Otherwise, you may need to sell it on Facebook Marketplace, Kijiji, or eBay to recoup your losses.

I can't return the device. I've had it almost a year. Well, I've got 5 months to find a replacement.
