联系您的网络供应商，索要解锁码。 如果您满足运营商的要求，他们就会将解锁码免费提供给您。解锁要求通常是，您需要将合约机费用付清，并且至少连续三个月使用该运营商的服务。
- 如果您向运营商解释您很快就要去国外旅行，并需要在当地买一个SIM卡以方便使用当地服务，他们可能更愿意解锁您的手机。
- 如果您的供应商不提供解锁代码，请尝试本指南中的其他方法。

收到解锁码后，关闭S3手机，然后取出旧的SIM卡。插入从其它运营商那里新办理的SIM卡。

当S3尝试连接到网络时，您会被要求输入解锁代码。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/9\/91\/Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-4-Version-2.jpg\/v4-460px-Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-4-Version-2.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/9\/91\/Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-4-Version-2.jpg\/v4-728px-Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-4-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

请确保输入正确的解锁码。如果您多次输入错误，手机将会被锁定，而您需要让运营商来为您解锁。当你输入正确的解锁码后，就可以连接到新网络了。

检索S3手机的IMEI号码。 打开手机上的拨号软件，在手机键盘中输入*#06#来获取手机的IMEI号码。接着，画面中会出现此代码。记下这个数字以备日后使用。
- 请确保写下IMEI号码，因为你无法将其复制到手机的剪切板中。
- 你也可以在S3电池下面的标签上找到印在上面的IMEI码。然而，我们不推荐您从盒子上或手机电池下方的标签中获取IMEI码，因为它可能与您的设备不符，这样你的解锁代码就没有用了。 ^{[1]

网上有许多在线解锁手机的收费网站。阅读用户评论来查看大家是否满意该网站的解锁服务。您需要提供您手机的IMEI号码。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/4\/49\/Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-7.jpg\/v4-460px-Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-7.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/4\/49\/Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-7.jpg\/v4-728px-Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-7.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

找到可靠的网站后，提供你的IMEI码。确保输入正确的运营商、机型和IMEI码。不要信任那些声称会免费帮你解锁手机的网站。如果他们提出让您填写调查或成为会员来获取你的代码，那多半是欺诈骗局。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/8\/8c\/Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-8.jpg\/v4-460px-Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-8.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/8\/8c\/Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-8.jpg\/v4-728px-Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-8.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

根据不同的服务，这可能需要几个小时或几天。您能通过短信、电子邮件或电话收到您的代码，具体方式取决于你选择的网站的政策协议。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/f\/fc\/Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-9.jpg\/v4-460px-Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-9.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/fc\/Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-9.jpg\/v4-728px-Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-9.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

确保新的SIM卡不是来自您原来的运营商的。当系统提示您输入解锁代码时，请输入您从网站收到的代码。请确认您能收到运营商的信号和服务，以及该代码是正确有用的。

插入新网络的SIM卡来查看你的手机是否真的被锁定了。事实上，许多S3合约机是没有被锁定的。提前检查能节省你大量时间。

更新您的手机。 您的手机必须运行Android 4.1.1或更高版本（可能不适用于某些安卓4.3系统的手机），以便于使用这个方法来解锁手机。您可以打开“设置”，然后滚动至底部，选择“关于设备”来检查您设备的系统版本。寻找Android版本来找到您的版本号。
- 要更新您的手机，请打开设置，然后向下滚动到关于设备。在接下来的菜单中，选择系统更新，然后检查更新。您的手机将通过网络尝试自动更新。
- 由于新的SIM卡还无法连接到网络，所以请通过无线网络来进行更新。

确保你的手机是GSM制式的手机。 你无法解锁运行CDMA网络的S3手机。在美国，Sprint、AT&T、威瑞森和T-Mobile都运行GSM网络，都允许你解锁手机SIM卡。
- 我们不能保证这个方法在所有版本的S3手机上都有用。不过，这个解锁方法没有任何危害，值得一试。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/2\/25\/Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-13.jpg\/v4-460px-Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-13.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/2\/25\/Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-13.jpg\/v4-728px-Unlock-Samsung-Galaxy-Siii-%28S3%29-Step-13.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

您将需要在拨号器中输入一个代码来打开服务模式菜单。打开拨号程序后，输入以下代码：*#197328640#。

等待约一分钟后，重启手机。你不会收到任何提示你操作已生效的确认消息。如果你的手机连接到新SIM卡的网络，那么说明解锁成功。 ^{[2]

小提示

请确保仅从可靠公司购买解锁码。有些公司会兜售假冒的代码。
在购买解锁码前请确保您的手机已被锁定。如果您在购买解锁码后发觉手机没锁，这种情况多数是不会退款的。
有些运行安卓4.3版本的三星盖世S3手机需要降级为之前的安卓版本（4.1或4.2），才能让解锁码生效。
