3G Connection Problem I have try to share my Samsung note 10.1 (Model Number : GT-N8000) portable hotspot last night  but it fail. After that, i cannot access to internet via data network mode(the 3G/H+ sign disappear next to my signal meter ) but the Wi-FI is functioning.

My tablets details are:
Model Number: GT-N8000
Android Version: 4.0.4
Baseband version: N8000XXLGA
Kernal Version: 3.0.15-861995-user se.infra@SEP-118#1
Build number: IMM76D.N8000XXALGA

If anyone has an idea why this would happen, please give me a shout. It's so frustrating having no data connection for the most of my day.
