Apple Watch Series 9 Cell Connection Options in Uruguay

I now have a series 2 iWatch connected to my iPhone 13Pro. Would like to get a series 9 with cell and connect with my Movistar plan here in Uruguay. I see Movistar in Chile listed as compatible, but nothing in Uruguay. Is connecting a line with Movistar here in Montevideo an option? If not, are there any cell carriers I could look at switching to? I've been very happy with Movistar plan and service in this country... I would like to stay with them!
