Is that prepaid or postpaid?
APN for Postpaid: internet.globe.com.ph
For Prepaid: http.globe.com.ph
For prepaid make sure you are registered to any surf promo. Atleast a 1.00 maintaining balance too.
prepaid daw hehe .. tama nmn apn nya hmmm better try to transfer the sim to other device any phone with mobile data will do just make sure the internet settings is configured also try to phone swap insert other sim card to your device that also have a data subscription and try to connect to internet this is for isolating the concern if it's with the device or with your sim card ..
