In the overwhelming majority of cases, when a new SIM card is installed, the smartphone automatically receives the MMS and mobile Internet settings. But sometimes failures can occur, as a result of which the user has to manually set the desired parameters. In this article we will tell you how to set up MMS on Android.
To open MMC settings, you need to do the following:
Step 1... Run the app Settings and select the section " SIM cards and mobile networks».
Step 2... Select the SIM card for which you want to set up MMS.
Step 3... Click the " Access points».
Step 4... Select an access point for MMS and in the next window set the parameters required for correct reception and sending of multimedia messages.
MMS hotspot settings differ for different mobile operators. To save your time, we have collected links to the corresponding MMS settings for gadgets running Android from the largest providers in Russia and neighboring countries:
How to send MMS from Android
Previously (on), to send MMS, you had to select the appropriate option in the message menu. In modern smartphones, everything is much simpler: just attach, for example, a photo to a text message, so that it is automatically converted into a multimedia message. This also works in the opposite direction - by deleting all multimedia files from the created MMS, you will turn it into an SMS message.
Conclusion
Setting up MMS on Android is very simple - just use this guide and in a couple of minutes you will be able to send and receive multimedia messages on your smartphone.
There are many apps that can easily backup messages or import saved copies back to your phone. But SMS notifications may contain important personal information that I would not like to trust programs from a third-party developer. Therefore, we will try to extract the necessary files manually. To do this, you need to find out where SMS is stored on Android.
Access to SMS
Directory that contains the file with MMS and SMS:
/data/data/com.android.providers.telephony/ databases / mmssms.db
The problem is that this file is stored in the protected memory of the Android OS. Alas, without root rights or ADB Shell, you will not get into this directory.
Export and import SMS manually
As a superuser, you can save SMS to a memory card using special Unix commands. To execute these commands, you need an Android terminal emulator and BusyBox application. From the BusyBox commands provided, use the copy command.
Export:
$ cp /data/data/com.android.providers.telephony/ databases / mmssms.db / sdcard /
Import:
$ cp /sdcard/mmssms.db /data/data/com.android.providers.telephony/ databases / mmssms.db
$ chown radio: radio /data/data/com.android.providers.telephony/ databases / mmssms.db
$ chmod 660 /data/data/com.android.providers.telephony/ databases / mmssms.db
Space before databases / not needed.
Any editor of the embedded relational sqlite database will help to open the file with the .db extension, for example

Mms messages is a service that allows you to transfer various files, including photos, pictures and animated images.
Sometimes there are situations when you need to edit received or sent media files, which is why the question arises, where are mms stored in android.
In general, all mms can be viewed in the "Messages" folder. But only viewing is available there, that is, it turns out that you cannot edit the received files in this folder.
Where are the received mms stored
- If you received an mms message, and the phone refuses to open the image, you can see it using the Internet. Most often, at the end of the message you can see the inscription "To read the message, follow this link."
- Click on it and enjoy viewing the file.
- If your device supports the mms function, and the settings are correct, then in most cases you will see the file sent to you when you open the message.
- All received mms messages are stored on your phone at this address: /data/data/com.android.providers.telephony/app_parts.
- Each of them is saved in the PART_1228000671287 format, which has no extension. That is, it turns out that you simply cannot open it.
Where are the files received from mms stored?
- When you open an image obtained in this way, you can save or delete it. To do this, hold your finger on the message, and then select the item you need in the window that appears.
- By pressing the "Delete" button, you permanently erase it from the memory of your mobile device.
- If you click "Save", then the picture will be available for opening at any time. You can find it in the "Download" folder, which is located in "My files" in the main menu.
- Here you can rename the image, delete it or send it by mms message to another subscriber.
User in specification terminology) is subscriber-side software that allows you to receive, send, view and process multimedia content on a mobile terminal.
For a communication exchange environment (it is difficult to find a Russian analogue of the English terminology exchange), the service user who sends and generates multimedia content is called the originator, while the service user who receives the sent content is called the recipient.
In order to be able to send a message to a subscriber, you need to know his current location (for example, a service provider), so the MMSC is also connected to.
MMSC is also responsible for temporary storage (cache mode) or permanent storage of messages (provision of MMBox service for subscribers).
Let's take a closer look at the part, specifically the MMSC (see the figure below), which is associated with storing messages.
In order to determine the options for storing multimedia messages on the side of the MMSC, it is necessary to take a closer look at the existing mechanisms for delivering these messages.
According to the specification, there is a so-called. immediate and deferred sending of MMS messages, which is defined on the recipient's side. Sending a message immediately is similar to the mechanism for delivering a message to a recipient, i.e. the message is delivered immediately after it is sent, but if it is sent, its content can reach significant sizes and the recipient may not be able to process it (does not have enough memory to store the message). In addition, this mechanism opens up ample opportunities for spammers to deliver intrusive content to the recipient. To avoid such situations, the specification has been added to the possibility of differentiated or deferred dispatch, the mechanism of which consists of two stages:
- The MMSC temporarily saves (starting from version MMS 1.0) a message for the recipient in the Temporary Message Store and creates a kind of notification for the recipient, which indicates the characteristics of the message (size, type, etc.).
- The MMSC informs the recipient that a certain message has been received for him with the help of the created notification, and the recipient himself "decides" whether he should accept the specified content immediately or a little later, based on his capabilities.
In the case of these two methods, the recipient has the right to use the following mechanisms in relation to the received message:
- Rejection of the message- reject message reception.
- Forward of the message- redirect the message to a remote mailbox, or to the address of another recipient.
Starting from version 1.2, the user is given the opportunity to store communications in the so-called. Multimedia Message Boxes ( MMBox) - in the network storage (Permanent Message Store) on the MMSC side. With MMBox, the user can:
- store sent / received multimedia messages;
- request messages from storage;
- save messages that have been forwarded to other recipients;
- load / delete / view already saved messages;
- redirect messages from storage to other users;
Actually, with the help of such mechanisms, my multimedia messages can be stored, which I send or receive on my mobile device.
Another rather interesting possibility of sending messages, in my opinion, is the so-called. response charge, which allows the sender to pay for all replies to his sent message from the recipient (s) by specifying several conditions that must be met by the recipient (s) to pay for the reply message. These conditions can be:
- response deadline - the sender of the message can specify that the response message will not be paid if the response is sent later than the specified deadline.
- reply size - the sender of the message can set the maximum size of the reply message, if the reply is larger than the specified size, it can be delivered to the sender of the message, but will not be paid for.
But that's a completely different story ...
