If I buy a Verizon Note 8 SM-N950UZKAVZW or Note 9 SM-N960UZPAVZW, will it work in Colombia or do I need to switch to AT&T? Some places I read say in Colombia CDMA phones will not work, but it appears the CDMA phones have the same bands plus CDMA. Perhaps it has something to do with SIMs and I have to switch to AT&T?

Thanks!
