Recommendation for low power LTE CAT-1

Hello, currently, I’m using LTE-M and NB-IOT for my IOT devices. However, I’m looking to find LTE CAT-1 or equivalent chips to test it out. Is there any solution that provides for a low-power solution. Looking to try LTE CAT-1 with EC21, but it appears that PSM is not supported.

Would appreciate any chip recommendation or advice.
