Phone cards are all about the same price. Pick one up just about anywhere. Just remember, the hotel or T/S may have some stupendous fees. Last time I was there and called from the room, the fees were 10 times the cost of the card on short calls.
Ok, thank you!
I just called Verizon, they said they charge $0.99/minute if I use my cell phone from Mexico because my plan doesn't have international calling plan.
They also said text message is $0.50 per sending and $0.05 per receiving.
Maybe I have to bring my Vonage phone and use it from there
This post may be too late for you to use since you are leaving shortly, but you'll want to check Mexitel Cellular before your next trip. Calls to the US and Canada are $1 per call (not per minute), incoming calls are all free, and they send the phone to you before you leave (so you have it at that so-ciritical time of luggage retrieval and hotel pick-up).
Almost forgot - Mexitel is on the web at www.mexitel.net
Hope this helps out - if not this time then next.
