You don't unlock with a new sim card. If you want to change carriers, you'll have to use a phone on their network. If you travel to many different countries, then buy an unlocked phone before you change sim cards.

Hard reset or update the firmware to solve this problem

Try a fresh reboot, then immediatly go to those settings. Maybe try this with the Sim removed.

This should be changeable in your settings menu. Under interface and then status bar. There are also downloadable apps to really start to customize the phone to your personal preference.

This will help to reduce the frequency of this issue occurring. I have the same problem and have not yet found a way to remove the Airplane Mode option form the action bar pull-down for the Z998 phone. It is a ZTE firmware issue, not Android. UNDERSTAND WHAT HAPPENS: when the phone moves slightly away from your ear while talking, the proximity sensor detects that it is not close to your face and it turns the display back on as it should. The screen often comes on with the action bar pulled down and thus all the controls exposed. A moment later your phone touches your ear before the proximity sensor had caused the screen to go blank again, so whatever your ear touches, can become an actual user command, even though unintentional. Unfortunately the Airplane Mode is one of the first selectable options on the Action Bar. You might sometimes notice that Bluetooth, Sound or Mobile Data gets toggle also; at least that does not cause you the dropped call. The problem gets worse when you walk or move around or fidget a lot while talking. THIS HELPS: manually turn the screen off (press the power button) after you answer the call. Because you deliberately power off the screen, the proximity sensor is bypassed. The job of the proximity sensor is to turn on/off the screen to save battery (the reason of course that when the phone is against your ear, you cannot possibly also look at the screen, hence the proximity sensor turns it off for you). You will soon get in the habit.

Its possible your battery is too low. Try giving it a full recharge while 100% off.

Jordan, If you've got the time, try Googling an open source copying program to pull your library from "the iTunes" and just plugging the songs into your device from USB. iTunes is heavily copyrighted and they want to keep us using their products exclusively so they mask the files with fake names under hidden folders/directories on the device and in iTunes. This is where you hear the term "proprietary" used in conjunction with Apple/Mac devices. Android is written using free Linux code at it's core and use the most basic user friendly approach to adding music. It may take a couple days to fix the metadata of your songs, but hey, you own them already, just need to get at em'! TRY THIS LINK: open source ipod copy Google Search

Try Kies instead. Download free like itunes
