Im using a prepaid sim and i activated the roaming while i was still in the philippines (right before my flight) and it said it would activate once i arrive to my destination. I got to guam no service, i got to hawaii no service, got to la no service and now im in san diego and still no service. Before i left i even bought 200 pesos worth of load. Need this so it would be easier for my friends and family to text me just incase of emergencies. What should i do?
