MmsService is a preinstalled system application on Android devices that is responsible for sending and receiving multimedia messages. A Multimedia Message Service(MMS) is a type of messaging service that allows you to send messages with multimedia content from one mobile device to another.

What is an MMS?

Multimedia Messaging Service(MMS) is a communication service developed by 3GPP that allows you to send and receive multimedia content including images, audio, GIFs, and videos via text message. An MMS also includes text messages where the character length is over 160 characters.

MMS message

While sending an SMS, if your character length is over 160 characters then your message will be split into two different messages whereas if you’re sending an MMS then you can use more than 160 characters and it will be sent as a single message.

You need to have a cellular data connection to send and receive MMS. Android devices don’t allow users to send and receive MMS over a Wi-Fi network, it only allows MMS over a cellular data network. However, Apple iOS devices allow you to send and receive MMS both over the cellular data network and Wi-Fi.

What is com.android.mms?

com.android.mms is the Application Package(APK) name of the built-in stock Messaging application in Android devices. The package name of the stock messaging app is not the same for all devices and it varies depending on the device manufacturer.

The package name of the stock Xiaomi MIUI messaging app is com.android.mms but the package name of the OnePlus stock messaging application is com.oneplus.mms. The package name of the stock Samsung messaging application is com.samsung.android.messaging.

What is MmsService Used For?

MmsService is a built-in system application that allows users to send and receive multimedia messages containing images, audio, GIFs, videos as well as text with over 160 characters right from your default Messaging application using your cellular data connection.

You don’t need to install a third-party messaging application to send MMS messages. You can do it using the built-in stock Messaging app on your device. You can send SMS and MMS both from the same messaging app.

The Application package name of the MmsService application in Samsung devices is com.android.mms.service.

Is MmsService a Virus or Is it Safe?

MmsService is not a virus, malware, spyware, or bloatware. It doesn’t cause any harm to your device and doesn’t spy or sell your data.

It is a safe application that is required to send and read the received MMS messages. It doesn’t consume your system resources unnecessarily. It only uses your cellular data when you send or receive the MMS message.

Although this system app is not a virus there is a possibility that an MMS message you received from someone contains a virus or malware. You should use an Antivirus app on your device and scan all the files including messages with this Antivirus app. You can also use an app called Malwarebytes that detects potential Malware on your device and removes them.

Spammers and hackers send MMS messages with links to harmful websites. If you click the link on that message you will be redirected to another website that inserts malware and viruses on your device. Therefore, you should never click on links inside MMS and SMS messages from unknown senders.

com.android.mms has stopped unexpectedly?

The com.android.mms package sometimes stops working out of the blue and you get an error message “com.android.mms has stopped unexpectedly” or “unfortunately com.android.mms has stopped.” This error occurs due to the corrupted app cache or overloaded app cache of the stock Messaging app.
