Unlocked Samsung Galaxy phones to work with XM - A10 A20 A50 A51 A70 A71 S9 S20

Hello,

I am an existing XM customer with current phone of Samsung S8+, I want to now change the phone to any of the above mentioned Samsung Galaxy phones (Unlocked).

I am reading all mixed comments on bringing unlocked phones to XM and its compatibility with XM, considering CDMA/GSM network bands etc.

If I do a sample IMEI test for any of these unlocked phones on the BYOP site, it turns out to be not compatible.

How do I know that what Samsung galaxy (unlocked) phone is supported by XM?

What is the exact criteria for my exisiting XM SIM to work with a new unlocked SIM?

For example - should it support CDMA or GSM

Should i look for particular Network bands for CDMA LTE etc?
