The thing is - If you’ve ever tried to send a file larger than 300kb using the Messenger app on your Android device, you will likely get an error message similar to the following:
Message size limit reached. Sorry you cannot add this video to your message.
You could use email instead, but if you really want to use an MMS text message, you can use a third party messaging solution like ChompSMS. ChompSMS can be downloaded from the Google Play.
Once you’ve downloaded and installed the app, open it and select “Menu” > “Settings“. You will see an option for “MMS Size Limit“.
Here you can increase the file size limit to 1MB or set it to have no limit at all.
The maximum file size for picture/video messages depends upon the device's network capability. See signal indicator on the phone to determine which signal is being received.
Basic Devices that are only 1xRTT capable (indicated by "1x" indicator) can send/receive a maximum file size of 350 KB.
Basic Devices that are Rev 0 EVDO capable (indicated by "1X") can send/receive a maximum file size of 500 KB.
Rev A EVDO (indicated by "3G") and 4G LTE capable (indicated by "4G" or "LTE") devices can send/receive a maximum file size of 1,200 KB.
Devices using Verizon Messages (Messages+) can send files up to 100 MB.
The maximum file size that can be sent from an email to a device as a Mult-Media Messageis 3 MB.
Larger files can be sent via email to email.
If a device sends a file to a device with a lower file size limit the file is reduced to a file size acceptable by the receiving device.
Many devices are capable of sending messages that exceed intercarrier file size limits (typically 300-600 KB). A message that exceeds the other carrier's limits is rejected and doesn't reach the intended recipient.
Lowering the camera resolution reduces the image file size.
Some Android devices have a Video Trimmer feature to reduce the size of the video allowing it to be sent via MMS.
