    Welcome to Android Central! Moved from the KitKat forum to the Galaxy Grand forum.

    What's the exact model number of your phone, and what carrier are you using? Are you certain the phone fully supports your carrier's network bands?

    You don't know who your carrier is? Where did you get the SIM cards from?

    Check to see if the APN settings are correct for Idea. Idea APN Settings For 4G 3G 2G Internet: Manual Data Configuration with APN

    If it works normally on other devices, then it's probably the phone itself.

    See if it happens in Safe Mode: How to turn on safe mode on Samsung Galaxy Grand 2. If it still happens, try wiping the cache partition: SAMSUNG G7102 Galaxy Grand 2 - Recovery Mode - HardReset.info

    If the problem persists, you might consider reinstalling the firmware using Smart Switch: http://www.sammobile.com/forum/showthread.php?t=29914
