Hopefully you were able to already get things working, but in case anyone else happens upon the thread and runs into similar issues, there were a couple of things in Info.plist that might have been contributing to the issue you were seeing and that other folks might also run into... It looks like you were using +63 for your country code and 0908 for your carrier code, but those would be for E.164 purposes. For the iOS Carrier Descriptors, you'll need your PLMN/IMSI identifiers, instead. If I'm interpreting +63 0908 correctly, you should, instead, be 515 for your MCC and 03 for your MNC. You also may need a public-cellular-plan string in your CommCenter.fine-grained array.
