Hi! I'm from the Philippines with Digitel/SUN network. I have Samsung Galaxy S3 Intl running latest build 2.11.30. I have switched to WCDMA Only mode since my mobile carrier recommends it because i have unlimited data plan. Whenever i lose network signal (zero bar), It switches to "emergency calls only". When i go back to the area that has a very good signal, it doesnt switch back to my network. It stays at "emergency calls only". Not unless i switch to airplane mode and back. I don't know if this is a bug or something but it needs to be addressed. I already have downloaded and applied the Offical CSC and Modems for 4.1.1 country specific (XTC). Same thing. Help. Thanks!
