Costs Associated With Using Phone in Mexico on Older Plan

Hola,

Could someone please tell me the costs associated with using my phone for data, text, and calling in Mexico? I am specifically interested in calling, as I am unable to determine whether it is included or $0.25 per minute. I tried to look on the website, but it only seems to include information for "Essentials" and "Magenta" plans. For reference, I have the Select Choice FAM UNL TT 50 plan. If there is a cost associated with data roaming and/or calling while in Mexico on this plan, is there an add-on that I can get for it?

¡Gracias de antemano!
