    Welcome to Android Central! How do you know it's not a network issue? Do other phones on the same network have no problems right next to you?

    Try using a can of compressed air to blow out the SIM slot or tray. Since the phone is new, I'd bring it back to the store for an exchange, or contact Samsung for warranty repair/replacement.

    I have the same issue! My s7 is 4 days old and is always losing cellular, data, and even wifi connection... I tried making a call and it won't dial. I can't send texts nor turn on data.
    I tried resetting the network configuration and it worked. Only half hour later I lost signal again.. PLEASE HELP.

    At 4 days old with that kind of issue, I'd return it it under warranty and have it replaced.

    I have the same issue, it only happens once or twice per week and I can fix it by toggling on/off airplane mode but that shouldn't happen
