My wife and I are going to Mexico for 2 weeks in Feb. She will be having kidney dialysis while there and we need to keep in touch through voice and text. What is the best plan for her phone and how do I set it up? She has a Samsung Galaxy S4. I have the same phone but with a different carrier.
If your phones are unlocked, buy 2 sim cards and plans from a carrier in Mexico. Less headache if you're only there for a short time. If not unlocked, maybe buy 2 prepaid phones and plans if that is cheap there.
