How To Use SIM Card Lock On Sony Xperia Tablet Z

Learn how to use SIM Card Lock on your Sony Xperia Tablet Z. The SIM card lock only protects your subscription. Your device will still work with a new SIM card. If the SIM card lock is on, you have to enter a PIN (Personal Identity Number). If you enter your PIN incorrectly more times than the maximum number of attempts allowed, your SIM card will become blocked. You need to enter your PUK (Personal Unblocking Key) and then a new PIN. Your PIN, PIN2 and PUK are supplied by your network operator.
