In which folder are mms downloaded to android. Where are SMS located on Android? How to send mms from android
There are many applications that can easily backup messages or import saved copies back to your phone. But SMS notifications may contain important personal information that you would not want to trust programs from a third-party developer. Therefore, we will try to pull out the necessary files manually. To do this, you need to find out where SMS are 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
With superuser rights, you can save SMS to a memory card using special Unix commands. To run these commands, you will need an Android terminal emulator and the BusyBox app. 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.

User in specification terminology) is software on the subscriber side, which 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 source (originator), while the service user who receives the sent content is the recipient (recipient).
In order to be able to send a message to a subscriber, you need to know its current location (for example, serving), so the MMSC is also connected to.
The MMSC is also responsible for temporary storage (cache mode) or permanent storage of messages (providing the MMBox service to subscribers).
Let's take a closer look at that part, specifically MMSC (see the figure below), which is related to the storage of messages.
In order to determine options for storing multimedia messages on the MMSC side, 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 (immediate) and delayed (deferred) sending of MMS messages, which is determined 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 in the case of its content can reach a significant size 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 wide opportunities for spammers to deliver intrusive content to the recipient. To avoid such situations, the specification introduced the possibility of differentiated or delayed sending, the mechanism of which consists of two stages:
- MMSC temporarily stores (starting with MMS 1.0) a message for the recipient in a temporary storage - Temporary Message Store and creates a kind of notification for the recipient, which indicates the characteristics of the message (size, type, etc.).
- MMSC informs the recipient that a certain message has arrived for him using 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 receiver is free to use the following mechanisms with respect to received messages:
- Rejection of the message– reject message reception.
- Forward of the message– redirect the message to a remote mailbox, or to another recipient's address.
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;
- download/delete/view already saved messages;
- redirect messages from storage to other users;
Actually, with the help of such mechanisms, my multimedia messages that I transmit or receive on my mobile device can be stored.
Another rather interesting possibility of sending messages, in my opinion, is the so-called. response fee, 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) in order to pay for the reply message. These conditions may be:
- response deadline - the sender of the message can specify that the response message will not be paid if the response is sent after the specified deadline.
- response size - the sender of the message can set the maximum size of the response message, if the response is larger than the specified size, it can be delivered to the sender of the message, but will not be paid for by him.
But that's a completely different story...
