If you've got a networking problem on your Korean Version of the S4, and you think that there is no other solution for you than to dump it, then maybe we can be the ray of sunshine you have been waiting for. There are a number of solutions for this problem, but if your problem is a pretty serious one, then maybe a Factory Reset is your last option. However, there are chances that it is something a little less serious and that it can be dealt easily. No matter what the original cause of the problem is, try out these solutions and see what works out for you.

1. 1
   Choose your operator manually

   .

   In normal mode, your phone automatically looks out for network signals and tries to configure it on its own. However, there is a chance that there is something wrong with this setting. You need to choose your operator manually. For this, just follow these steps:

   

    

   1. Go to "Settings".
   2. Choose "Wireless and networks".
   3. Choose "Mobile networks".
   4. Now, go to "Network operators".
   5. Lastly, go to "Choose Your Operator", and choose any operator/network that is not 02. Once you have chosen this, you need to locate "Unable to Connect". Once you have located this, select 02 again. Now, switch back to "Automatic". Restart your phone.

   Check for the Airplane Mode

   .

   There is a huge chance for this possibility. Many times, users accidentally switch to "Airplane Mode". Airplane Mode is the mode in which you are unable to send or receive messages or call. You need to make sure that the Airplane Mode is off and your phone is in Normal mode.

3. 3
   Disabling the Wireless Networks

   .

   If your "Use Wireless Networks" option has been accidentally checked off, then your phone will not be able to receive any signals whatsoever. Make sure that this option has been selected, so that your phone can successfully catch signals. For this purpose, follow these steps:  

   1. Go to "Settings".
   2. Choose "Location Services".
   3. Now, select "Use Wireless Networks".
   4. This should pretty much solve your problem.

   Perform a Factory Reset

   .

   If none of the solutions have worked out for you, then maybe you're in trouble. This is your last option, and if the phone still doesn't show any progress, then there must be some internal defect in it. You would have to take your phone to the company and ask them to repair it. There may be some problem with your SIM card slot. Whatever the issue is, the technicians at the company will likely be able to help you in this regard.

   A quick note

   :

   Before you set out on the mission of resetting your phone, make sure you save all your data on your PC. For this, you can use any backup application. The most recommended one is Samsung Kies. Use it to make a backup copy of your entire data. Once you have stored all your data on your system, you can apply the Factory Reset on your phone. Then reboot your phone and check whether things have worked out in your favor or not.

This may be happening because your mobile network recognizes that this device is a clone and is not an original device. From here you will need to contact your mobile carriers customer service in order to help connect your device/SIM to your mobile network successfully.

My network connection is Showing H+ but net is very slow?

In my Korean Galaxy S4 copy m facing this problem

This sometimes happens when you have too many apps running at the same time. You may want to close down some apps and then observe if you still encounter the same problem. In some cases when net is very slow, it does not always have to be a problem with the connection.

Also, this may be because your current location has a very bad signal. It does not show you that you've lost your connection but it gets stuck in the previous H+ status but actually, your connection has gone off already. You may want to go to another place with a stronger signal.

I have S4, and when I boot, there is no signal, it shows, (Emergency call only - GLOBE) how to fix this?

I already cut the stickers on the lower back of S4, I think it is used for the signal bar?

I have read that the sticker that you have in fact removed is used to generate a signal from your device. When you, in fact, remove the sticker or back plate to the device you will remove the ability for your device to access signal. You are going to need to in fact:

-Contact your carrier in order to be able to receive a new back plate to your device so that you will be able to pick up signal on your device. This will allow you to once again be able to generate signal from your device.
