mobile

hi guys, just flashed my GT-I9505 with the LOLLIPOP hat i got here in XDA and its very good. no lags but sometimes the music app freezes and you need to remove the bettery to fix it. the worst is the mobile data connection, i have an exclamation mark on my sim signal and when i try to open data, nothing happens. I am here in the philippines and I am using TOUCH MOBILE sim card, i changed my sim to globe, one of the largest network here and the issue is not happening. still have the ex mark on the signal bar but i can connect to the internet. do you guys have a resolution for my issue? i am having a hard time now as i need to use my laptop to access the internet. help me guys
