发生此错误的原因有多种。这可能是由于互联网连接速度慢或存储空间不足。但是，如果此问题无法自行解决，则您需要自行解决。在本文中，我们将介绍一些您可以尝试解决彩信(MMS)下载问题的简单解决方案。
解决彩信下载问题的 8 种方法
方法一：重启手机(Method 1: Reboot Your Phone)
不管(Irrespective)问题如何，简单的重启总是有帮助的。这是您可以做的最简单的事情。这听起来可能很笼统和模糊，但它确实有效。就像(Just)大多数电子设备一样，您的手机在关闭再打开时也会解决很多问题。重新启动手机将允许Android系统修复任何可能导致问题的错误。只需(Simply)按住电源按钮，直到电源菜单出现，然后单击Restart/Reboot option。手机重启后，检查问题是否仍然存在。
方法 2：(Method 2: )检查您的 Internet 连接(Check your Internet Connection)
多媒体(Multimedia)信息需要稳定的互联网连接才能下载。如果您的设备上没有可用的互联网连接，那么您根本无法下载它。从通知面板向下拖动(Drag)，确保您的Wi-Fi 或移动数据已打开(Wi-Fi or mobile data is switched on)。为了检查连接，请尝试打开浏览器并访问一些网站，或者在YouTube 上(YouTube)播放视频。如果您无法通过Wi-Fi下载(Wi-Fi)彩信(MMS)，请尝试切换到您的移动数据。这是因为很多网络运营商不允许通过 Wi-Fi 下载彩信。(do not allow MMS download over Wi-Fi.)

方法五： (Method 5: )清除缓存和数据(Clear Cache and Data)
每个应用程序都以缓存文件的形式保存一些数据。如果您无法下载彩信(MMS)，则可能是由于残留的缓存文件已损坏。为了解决这个问题，您可以随时尝试清除应用程序的缓存和数据(try clearing the cache and data for the app)。按照以下步骤清除Messenger应用程序的缓存和数据文件。

该错误可能是由第三方应用程序引起的。通常，任务终止应用程序、清洁应用程序和防病毒应用程序会干扰设备的正常运行。他们可能负责阻止MMS的下载。在这种情况下，最好的办法是卸载这些应用程序（如果有）。从任务终止应用程序开始。如果这解决了问题，那么你很高兴。
否则，请继续卸载手机上存在的任何清洁应用程序。如果问题仍然存在，那么下一个将是防病毒软件(antivirus software)。但是，完全卸载防病毒软件并不安全，因此您可以暂时禁用它，看看它是否能解决问题。如果这些方法都不起作用，那么问题可能出在您最近下载的其他第三方应用程序中。
确保这一点的最佳方法是以安全模式启动设备。在安全模式下(Safe mode)，所有第三方应用程序都被禁用，只剩下预装的系统应用程序。如果您能够在安全(Safe)模式下成功下载彩信(MMS)，则可以确认罪魁祸首是第三方应用程序。因此，安全(Safe)模式是诊断设备问题原因的有效方法。重启进入安全(Safe)模式的一般步骤如下：

2.现在，点击并按住关机(Power)选项，直到屏幕上弹出重新启动到安全模式选项。(Reboot)

您可以转向更好的替代方案，而不是被过去的技术所束缚。有许多流行的消息和聊天应用程序允许您使用互联网发送照片、视频、音频文件、联系人、位置和其他文档。与为MMS(MMS)收取额外费用的默认消息服务不同，这些应用程序是完全免费的。WhatsApp、Facebook Messenger、Hike、Telegram、Snapchat(Apps like WhatsApp, Facebook Messenger, Hike, Telegram, Snapchat)等应用程序是当今世界上使用最广泛的一些消息传递应用程序。您还可以使用这些应用程序免费拨打语音电话和视频电话。您所需要的只是稳定的互联网连接，仅此而已。这些应用程序具有许多很酷的附加功能，并确保比默认消息传递应用程序更好的用户体验。我们强烈推荐你考虑切换到这些应用程序之一(consider switching to one of these apps)，我们确信一旦您这样做，您将永远不会回头。
方法 8：(Method 8:) 执行出厂重置( Perform a Factory Reset)
如果没有其他方法，并且您真的想使用您的消息应用程序下载彩信(MMS)，那么剩下的唯一选择就是恢复出厂设置(Reset)。这将擦除手机中的所有数据、应用程序和设置。您的设备将恢复到您第一次拆箱时的状态。不用说，所有的问题都会自动解决。选择恢复出厂设置会删除您所有的应用程序、它们的数据以及其他数据，例如手机中的照片、视频和音乐。由于这个原因，建议您在恢复出厂设置之前创建备份。当您尝试将手机恢复出厂设置(factory reset your phone)时，大多数手机都会提示您备份数据。您可以使用内置工具进行备份或手动进行备份，选择权在您手中。
1. 进入手机设置(Settings)。
2. 点击系统(System)选项卡。

MMS stands for Multimedia Mеssаging Service and is a meanѕ to share photos, videos, audio clips, via the in-built messaging service present in Android devices. Although the majority оf users have shifted to using Messaging apps like WhatsApp, Telegram, Facebook Messenger, etc., there’s still plenty of people who prefer using MMS and that’s fine. The only frustrating problem that many Android users have often comрlained about is being unable to download MMS on their device. Every time they click on the download button, the error message “Couldn’t download” or “Media file unavailable” is displayed. If you are also facing similar trouble in downloading or sending MMS, then this article is for you.
There are multiple reasons why this error occurs. It could be due to a slow internet connection or a lack of storage space. However, if this issue does not get resolved on its own then you need to resolve them yourself. In this article, we are going to cover some simple solutions that you can try to fix the MMS download problems.
8 Ways To Fix MMS Download Problems
Method 1: Reboot Your Phone
Irrespective of the problem, a simple reboot can always be helpful. This is the simplest thing that you can do. It might sound pretty general and vague but it actually works. Just like most electronic devices, your mobiles too resolve a lot of problems when turned off and on again. Rebooting your phone will allow the Android system to fix any bug that might be responsible for the problem. Simply hold down your power button until the power menu comes up and click on the Restart/Reboot option. Once the phone restarts, check if the problem still persists.
Method 2: Check your Internet Connection
Multimedia messages require a stable internet connection to get downloaded. If there is no internet connection available on your device, then you simply can’t download it. Drag down from the notification panel and make sure that your Wi-Fi or mobile data is switched on. In order to check connectivity, try opening your browser and visit some websites or maybe play a video on YouTube. If you are unable to download MMS over Wi-Fi, then try switching to your mobile data. This is because a lot of network carriers do not allow MMS download over Wi-Fi.

Method 3: Enable Auto-Download MMS
Another quick fix to this problem is to enable auto-download for MMS. The default messaging app on your Android smartphone allows you to send both SMS and multimedia messages. You can also allow this app to automatically download MMS as and when you receive it. Follow the steps given below to learn how:
1. Open the default messaging app on your device.
2. Now tap on the menu button (three vertical dots) on the top right-hand side of the screen.
3. Click on the Settings option.
4. Here, tap on the Advanced option.
5. Now simply toggle on the switch next to Auto-download MMS option.
6. You can also enable the option to Auto-download MMS when roaming options if you are not in your country.
Method 4: Delete Old Messages
Sometimes, new messages won’t get downloaded if there are too many old messages. The default messenger app has a limit and when that is reached no more messages can be downloaded. In this situation, you need to delete old messages to free up space. Once the old messages are gone, new messages will automatically get downloaded and thus fix the MMS download problem. Now, the option to delete messages depends on the device itself. While some devices allow you to delete all messages in a single click from the Settings others don’t. It is possible that you might have to select every message individually and then delete them. This might seem a time-consuming process but trust me, it works.
Method 5: Clear Cache and Data
Every app saves some data in the form of cache files. If you are unable to download MMS, then it might be due to the residual cache files getting corrupted. In order to fix this problem, you can always try clearing the cache and data for the app. Follow these steps to clear the cache and data files for the Messenger app.
1. Go to the Settings of your phone then tap on the Apps option.
2. Now, select the Messenger app from the list of apps. Next, click on the Storage option.
3. You will now see the options to clear data and clear cache. Tap on the respective buttons and the said files will be deleted.
4. Now, exit settings and try downloading an MMS again and see if you’re able to fix MMS Download Problems.
Method 6: Eliminate Problem Causing Apps
It is possible that the error is being caused by a third-party app. Usually, task killing apps, cleaner apps, and anti-virus apps interfere with the normal functioning of your device. They might be responsible for preventing the download of MMS. The best thing to do in this situation is to uninstall these apps if you have any. Start with task killing apps. If that solves the problem, then you are good to go.
Otherwise, proceed with uninstalling any cleaner app that’s present on your phone. If the problem still persists, then the next in line would be the antivirus software. However, it wouldn’t be safe to uninstall an anti-virus completely so what you can do is disable it for the time being and see if it resolves the issue. If none of these methods work, then the problem might be in some other third-party app that you recently downloaded.
The best way to make sure of that is to boot your device in safe mode. In Safe mode, all third-party apps are disabled, leaving you with only the pre-installed system apps. If you are able to download MMS successfully in Safe mode, then it is confirmed that the culprit is a third-party app. Thus, Safe mode is an effective way to diagnose what is causing the problem in your device. The general steps to reboot into Safe mode are as follows:
1. Firstly, press and hold the Power button until the Power menu pops up on the screen.
2. Now, tap and hold the Power off option until the Reboot to safe mode options pops up on the screen.
3. After that, simply click on the Ok button and your device will start rebooting.
4. When the device starts, it will be running in Safe mode, i.e. all third-party apps will be disabled. You can also see the words Safe mode written in the corner to indicate that the device is running in Safe mode.

Method 7: Switch to a Different App
Instead of being stuck with a technology of the past, you can move on to better alternatives. There are a lot of popular messaging and chatting apps that allows you to send photos, videos, audio files, contacts, location, and other documents using the internet. Unlike default messaging services that charge extra money for MMS, these apps are completely free. Apps like WhatsApp, Facebook Messenger, Hike, Telegram, Snapchat are some of the most widely used messaging apps in the world today. You can also make voice calls and video calls for free using these apps. All that you need is a stable internet connection and that’s it. These apps have a lot of cool additional features and ensure a much better user experience than the default messaging app. We would strongly recommend you consider switching to one of these apps and we are sure that once you do, you’ll never look back.
Method 8: Perform a Factory Reset
If nothing else works and you and really want to use your messaging app to download MMS, then the only alternative left is a Factory Reset. This would wipe all data, apps, and settings from your phone. Your device will return to the exact same condition it was when you first unboxed it. Needless to say, all the problems will automatically be solved. Opting for a factory reset would delete all your apps, their data, and also other data like photos, videos, and music from your phone. Due to this reason, it is advisable that you create a backup before going for a factory reset. Most phones prompt you to back up your data when you try to factory reset your phone. You can use the in-built tool for backing up or do it manually, the choice is yours.
1. Go to Settings of your phone.
2. Tap on the System tab.
3. Now if you haven’t already backed up your data, click on the Backup your data option to save your data on Google Drive.
4. After that click on the Reset tab.

As mentioned earlier, sometimes the problem with MMS arises due to the carrier company. For example, some companies do not allow you to send files over 1MB and likewise wouldn’t allow you to download files over 1MB. If you continue to face this problem even after trying all the above-described methods, then you need to talk to your network service provider or carrier. You can even consider switching to different carrier services.
