Ernesto needs a new cell phone for his father. He doesn't do any smart things like apps or texting. He just talks. He wants one that will work between the US and Mexico. Leo says that a "feature phone" is an easy and inexpensive purchase. Alcatel is one brand that works in both places. He should go to T-Mobile and he can probably get one for free on a pay as you go plan. They also offer free international data and cheap international calls. It'll also work in 190 other countries as well. The chatroom says that AT&T is best in Mexico.
