First of all do check if your phone is capable of running a 3G SIM card. (This can be checked on your phone's specification list)If your phone is capable of running a 3G SIM card and still doesn't connect to a 3G network follow these steps :1.Go to your phone's settings.2. Go to SIM cards and mobile networks.3.Choose your appropriate SIM card. (In my case it's BSNL and I use single SIM)4. Choose preferred network type from this listSelect whichever network type you want to have. Try rebooting your phone once you finish these steps.If the problem again shows up it is better you contact your customer care and support.Note : I'm using Xiaomi redmi note 3. The settings panel might be different for the phone that you're using.
How can I unlock a ZTE phone without the pin and without resetting and losing the data?
If its bootloader is unlocked and a recovery has been flashed there are several possibilties. My recovery has the option fix lockscreen. This simply removes the lockscreen secirity such as my fingerprint authentification or a pin code. Most recoveries don’t have this option though. They however have a file manager. All you have to do is find a file called android.keygard (or something like that) and delete it. There are many tutorials on xda that can help you.If your phone does not have a custom recovery you can use the google device manager and login with the google account you use on your phone to unlock it. Thid requieres your phone to have internet access.
