My family and I are traveling to the PI in December arriving in Terminal 2. We have a 2-hour layover until we catch our next flight from Terminal 2. I'd like to get a free SIM Card from Terminal 2 at Ninoy Airport.The promo description only states Terminals 1, 3 and 4. Is it possible to go to one of the other terminals to pick up the SIM and return to Terminal 2 back in time? If yes, which terminal do you recommend 1 or 3?
