SIM card for iPhone in Mexico City

(posted also on Mexico branch)

Hi - I always buy a prepaid SIM card when I'm in Mexico. I buy an Amigo kit from Telcel and use it in my Samsung Android phone. Works like a charm. I want to do the same on my next trip but using an iPhone. I know the chip size is different, does anyone know whether the Amigo option would work with an iPhone (and the right sized SIM)?

Thanks - Andrew
