什么是APN设置，它们如何解决预付费电话上的数据问题？

购买预付费手机可以为您节省很多钱，而且缺点很少。这些缺点之一可能包括数据接收问题。要解决此问题，需要配置您的接入点网络（APN）设置。此过程需要花费您几分钟的时间，然后，您手机的数据连接将按照广告中的说明进行。不利的一面是，此过程因您所用的手机型号以及提供无线服务的人而略有不同。

If you sign up with a Mobile Virtual Network Operator (MVNO), which leases broadcast spectrum from the big carriers, you might need to configure your phone’s APN settings. The process is simple, although varies from MVNO to MVNO. This article covers what APN settings are, as well as some of the automatic configuration tools provided by MVNOs. Specifically, I illustrate APN settings using the configuration instructions provided by AirVoice Wireless, Straight Talk and Ptel. For those of you with iPhones, some carriers, such as Ptel, include automatic setup instructions for your phone. Also, if you have an iPhone and are also looking for a better carrier, check out our list of the best iPhone prepaid plans .

什么是APN设置？

Access Point Names are composed of several settings. These settings are essentially text fields that you must fill in in order to connect to data services. APNs exist because carriers broadcast and receive data over government regulated radio frequencies. Each phone must be specially configured to use these settings or otherwise potentially suffer from data connection issues, such as the inability to send MMS or use mobile data.

这四个最重要的APN设置是：

  • APN ：大多数MVNO运营商的接入点名称为“批发"。在美国以外地区有所不同。
  • APN类型：有四种APN类型-通用，sulp，mms和wap。这些因载体而异。如果您在使用官方设置说明时遇到问题，则“通用"始终是一个很好的默认设置。
  • MMSC ：大多数MVNO的MMS功能都需要此设置。它代表多媒体消息服务。如果您不使用彩信，则这不是必需的功能。
  • 代理：我没有在任何MVNO中使用此功能，但这可能是必需的。

    • 收到配置设置后，请注意，除非特别提示，否则无需更改设置。因此，例如，如果您的MNC设置为260，除非您的MVNO要求您进行更改，否则请勿更改此设置。

    配置APN设置

    To get started configuring APN settings, go to Settings -> Wireless & Networks -> More -> Mobile Networks -> Access Point Names. From here, you can configure your device to function on your specific MVNO. This process varies slightly from Android version to Android version, but more or less these are the steps that most people will need to take to access their APN settings. One important note is that you must tap the Menu button and choose to save your APN settings when you’re done entering them — hitting the Back button will simply undo your work. Also erase, or write over, the default APN settings.

    我还提供了指向AirVoice Wireless，Ptel Mobile和Straight Talk的特定APN设置设置提示以及一些iPhone APN设置。本文结尾处还有一些链接，涵盖了所有主要国家和运营商的APN设置。如果此处未涵盖您的运营商，则可以尝试搜索您的运营商+“ APN设置"，这可能会提示安装说明。您可能还需要按照运​​营商的数据和MMS设置说明来搜索适当的步骤。

    您看到的其他设置不需要其他输入。您可以将它们保留为默认值或空白。

    AirVoice Wireless采用了所有MVNO中最详细的设置说明之一。只需导航到他们的说明并输入您的手机型号即可。

    只会询问您是要设置MMS（发送图片）还是WAP（互联网/数据）。<

    在此处，按照说明输入设置。这些在我的Nexus 4上完美工作。手动配置非常简单。只需将配置设置与您的设备进行匹配即可。

    Ptel Mobile除了手动输入APN的选项外，还包括一个自动APN设置配置器。我建议至少看看自动配置器并输入您的IMEI号码。此方法会将APN设置直接发送到您的手机。它还包括 iPhone配置说明。

    手动输入方法更可靠。如果Ptel不包含您手机的设置说明，则只需查找具有类似数据功能的手机即可进行设置。如果不是这样，您始终可以在Google或具有更好功能的备用搜索引擎上搜索适当的设置。

    Straight Talk的APN配置说明需要手动输入，尽管这些很简单。只需在您的配置器中输入您的电话号码或SIM卡号码，您就会收到设置说明。

    有几个网站可以很好地解释每个国家/地区的MVNO的各个设置。最好的来自Unlockr.com。

  • 解锁：涵盖所有主要国家/地区和Android运营商的特定APN设置。
  • PrepaidPhones：涵盖Net10和iPhone的Straight Talk设置， Android和Windows Phone。

    • 结论

    Dealing with the problems caused by improperly configured APN settings remains the biggest stumbling block to signing up with an MVNO, and also when connecting using a prepaid SIM card in a new country. MVNOs will save you hundreds a year on your cellular bill Seriously, you should never sign a contract with a major carrier unless someone else pays your bills.
