Just curious. What happens to older devices that are using Telus' 3G and HSPA data but WCDMA for voice calling

Sure, they were built and operated as separate networks but In the east, Telus customers did have access to Bell CDMA towers, and in the west, Bell customers did have access to Telus CDMA towers.  Neither charged the customer extra for this. Bell and Telus have had a cozy relationship with each other long before the HSPA network build.

The reciprocal roaming agreement that Bell and Telus had in the CDMA days was the very reason Telus was able to offer reasonably reliable service in Ontario.  The Telus CDMA network was largely just the old Clearnet network, which honestly, wasn't very good.

W-CDMA (UMTS/HSPA) is different from CDMA (1x and Ev-DO).

They are completely independent networks.
Telus CDMA was built by Nortel, the phones are very old and do not use SIM cards. The network is not shared with Bell.

Telus UMTS/HSPA/W-CDMA was built by
Huawei and Nokia. This is the newer 3G network (even though they call it 4G), the phones are new, including iPhone, and all phones use SIM cards. The network (radio access) is completely shared with Bell.

CDMA, in this case, refers to much olders phones that don't even use sim cards.   This is the network that is being shut down. Telus customers within those phone will eventually need to switch over.

The HSPA network is not being shut down and WCDMA is still the primary technology for voice calls.
