You might have come across the package com.android.mms once or twice over the years on your android smartphone. It might be when you were checking your Google Activities. Or you might have received an error like “com.android.mms has stopped working”. We’ll be looking at all these problems. Later, we will also learn about the different ways we can use to solve these problems. First of all what is this package “com.android.mms” that I keep writing all about? It’s a built-in Android package that the Android OS uses for its Messages app.
For the next few words, we will dive into a brief history of MMS and different standards of sending messages. So, let’s jump in.
Short Message Service
Also known as SMS, is a standard of sending and receiving text messages. The first text message through SMS was sent on December 3, 1992, by Neil Papwort. It then went on to become wildly popular and the industry standard for text messaging services on most phones. SMS messaging business is reported to be worth over USD100 Billion as of 2018.
The procedure by which SMSs are sent follows:
- Messages are sent to a short message service center (SMSC) that acts as a store and forward server.
- The SMSC then tries to send the message to the SMSC’s recipient.
- If the recipient is unavailable for some reason, the message gets queued for a later retry.
SMSs also support the forward and forget feature which tries sending the message just once and never retries if failed.
In 2010 almost 6.1 Trillion SMSs were sent all across the globe.
In 2014, the Caktus group developed the first SMS-based voter registration system in Libya.
Even though SMS is still a growing market, it is constantly being challenged by new technologies like Whatsapp, Viber, WeChat, Apple’s iMessage, and many more. Since in the US, these services have not become much popular SMS still remains high in use.
Outside of the GSM technology SMSs are also used by 3G for its text messaging service. Some other alternative services built on the same technology are ShortMail and SkyMail.
Unlike some other technologies like SNPP or Motorola’s ReFLEX protocols, SMS is highly unreliable. It doesn’t give you the guarantee of delivery for the message. On top of that many implementations provide no means of finding out if the message has been delivered or not. Studies have shown that 1% to 5% of messages are lost even under normal working conditions.
SMS on top of this also suffers from several security vulnerabilities. This is because the only airway traffic is optionally encrypted by a weak and broken stream cipher.
Multimedia Message Service
Better known as MMS is the standard method of sending messages that include some form of multimedia. MMS extends the capabilities of SMS, which only allows messages up to 160 characters in length. Also, MMS allows using up to 5000 characters. The MMS can be used to send/receive multimedia files like pictures, videos (up to 40sec in length), and even slideshows.
During the early 2010s, MMS saw an increased messaging rate of up to 70% with more than 96 Billion MMSs being sent in a year. This was credited mainly to the rising popularity of smartphones.
The procedure by which an MMS is sent is a little different than SMS:
- First, the multimedia message is encoded by the sending device in a similar manner to a MIME message.
- This message is then sent to your carrier’s store and forward server. (The server is also known as MMSC)
- When relaying messages between two different carriers, the sender MMSC sends the message to the receiver MMSC.
- The receiver MMSC then forwards the message to the recipient
If the recipient device is not capable of viewing an MMS, the message is delivered by a web-based service. This message can be viewed via an internet browser.
Development of the MMS standard is continued by Open Mobile Alliance (OMA). OMA is a standards body that develops open standards for the mobile phone industry.
Even though MMS has many advantages over SMS, it still has some challenges that do not exist with SMS:
- Since multimedia formats supported by different devices vary, a multimedia file doesn’t need to be compatible with the recipients’ device
- The flow of p2p MMS messaging needs a large number of over-the-air transactions which becomes inefficient with MMS.
Even if there is a delivery failure the recipient still receives an SMS fallback message.
com.android.mms is the package that the Messages app uses for sending and receiving multimedia messages. Irrespective of the brand or company almost every Android phone contains this built-in package. This is because MMSs are still very high in use. The same package also appears on the google activity page whenever you use the MMS feature. Whenever you send a multimedia message or a message with more than 160 characters this particular package comes into play.
Now let’s talk about how you can send MMSs on an Android smartphone:
Sending an MMS
Sending an MMS is a pretty straightforward process and the procedure is pretty much the same across all smartphones. First of all, you have to ensure that you have a working cellular network that supports MMS services.
Next, you need to follow these steps:
- Open up the Messages app on your smartphone.
- Compose a new message.
- Enter the receivers, in the recipient’s field.
- Tap the camera button to click a new picture to send. Or you can also tap the gallery button to select a picture from the library to send it.
- Enter some text for context if needed.
- Press the send icon.
If everything goes alright, you’ll get a small Message Sent notification.
If it doesn’t then you might need to troubleshoot your MMS service. Most probably the APN isn’t set up properly
Set up APN
Follow these steps to set up the proper MMS APN for your ISP:
- Open up the Settings app on your smartphone.
- Tap on the Connections menu
- Go to Mobile Network and press the Advanced dropdown.
- Tap on the Access Point Names
- Tap the three-dot icon on the top right of the screen and select the Add option.
- Fill in the proper info about your ISPs APN in their respective fields. You can use this link for getting info about your particular ISP.
- Tap the Save button.
MMS should be working now. If it doesn’t then there is a good amount of probability your carrier doesn’t have an active MMS plan.
