Why rent when you can buy a phone from Verizon for $1,050 pesos and they include a $450.pesos phone card. That is what we did and it works great, no contracts and the phone is yours for next year. Bought our at Verizon at Janet's.
Take your triband cellular with you and buy a prepay card
Do the prepaid cards include a sim? I have a unlocked quad band gsm phone, but no sim?
