You mean wag gumamit ng default Apn?here's the trick.... don't use the standard globe apn or any of those. .
Idol na block na ako Wala na kahit signalyup... be sure to have a non-default globe apns. you can create your own apn's or you can search on this thread na may customise apn regarding sa iwas blocking.. pag humina, airplone mode agad habang naka on data.. let it leave for a while for at least a minute. the stop the ha tunnel while your on an airplane mode. then change the server (dapat ibang country) then change its port too. then airplane mode off agad. then start it again
