How to fix a Samsung Galaxy C7 Pro that won't send MMS [Troubleshooting Guide]

Before you troubleshoot, check and ensure that MMS is properly set up or enabled on your device. Typically, network services like MMS are automatically set up with your SIM or network. Otherwise, you’ll need to set up manually. If you’re relying on Wi-Fi Internet for MMS services, then your phone must be connected to Wi-Fi. If you’re using MMS services via cellular network, cellular data or mobile data must be turned on and that you have enough account credits to use. Note that data charges are applied when using MMS services via mobile data. Also ensure that your phone can access your network and that Airplane mode is disabled.

Aside from account-related issues, such problem can also be due to network problems like No service or No network access usually from an outage. In that case, you will need to deal with network connectivity issues first in order to get your network services, particularly MMS back up and working properly again. Otherwise, troubleshoot software problems that may have halted your Galaxy C7 Pro from sending MMS messages.

First solution: Restart your phone (soft reset).

If this is the first time you encounter an issue on sending and receiving MMS on your Galaxy C7 Pro, then it’s likely just a random glitch that’s easily rectified by a soft reset or device restart. Here’s how:

Press the Power button for a few seconds and then release when the menu options appear.
Tap Power off then OK. Your phone will then shutdown.
After 30 seconds, press the Power button again until the phone powers on.

A soft reset does not affect any saved data on your phone’s internal memory and so there’s no need to create backups.

Second solution: Update your phone software to the latest version.

Software bugs and malware can also mess up network functions on your phone. In that case, you’ll have a higher chance of resolving the issue by updating your device software or installing the latest software/Android version available for your phone. To manually check for updates on your Galaxy C7 Pro, follow these steps:

Tap Settings from the Main menu or Apps screen.
Scroll to and tap System Updates.
Tap the option to Check update manually.
If an update is available, follow the onscreen instructions to download and install update on your phone. Make sure your device is connected to Wi-Fi internet and has sufficient power and memory space to finish updating.

Software updates can free your device from any sort of malwares including those that are embedded into some MMS file attachments.

Third solution: Reset APN/network settings on your Galaxy C7 Pro.

Resetting the APN settings will reset MMS settings on your phone to default and therefore can potentially solve the problem if it’s mainly due to invalid settings or incorrect network configurations. Here’s how to reset APN settings on your Galaxy C7 Pro:

Tap the Apps icon from the Home screen.
Select Settings.
Scroll to and tap Mobile networks.
Tap Access Point Names.
Tap MORE.
Select the Reset to default option.
Read the message prompt and then tap RESET to confirm.

Your phone will then reset to default Internet and MMS settings and at this point, MMS issues should be fixed. To find out, try to create a sample MMS message and then send it to your own number. If you can send and receive the message, then you’re good to go. Otherwise, continue to troubleshoot by setting up MMS manually on your phone. Here’s how:

Go back to Apps-> Settings-> Mobile networks-> Access Point Names menu.
Then tap ADD.
Enter the required MMS information. If you’re not sure of what information to enter, contact your carrier or network service provider to get the correct MMS information.
After filling up all the required values, tap MORE then select SAVE. Doing so will save and apply the recent changes you’ve made.

Reboot your phone to refresh the system and internal memory and then try to see if MMS is already working as intended.

Fourth solution: Wipe cache partition on your Galaxy C7 Pro.

It’s also imperative to wipe cache partition to get rid of corrupted cache or temporary data that might have caused trouble on the phone network system and eventually halted MMS functions. If you just started to have trouble sending or receiving MMS after installing a new app or software update, then wiping cache partition would be necessary. Here’s how:

Turn off your phone completely.
Then press and hold the Power, Home, and Volume Up buttons simultaneously for a few seconds.
Release the Power button when the Samsung logo appears.
Release the Home and Volume Up buttons when the Android system recovery screen appears.
On the Android Recovery menu, press the Volume Down button repeatedly to scroll to and highlight Wipe Cache Partition option.
Then press the Power button to confirm selection.
Wait until the cache partition clearing is finished and the Reboot system now option is highlighted.
Finally, press the Power button to restart your phone.

Try to send a sample MMS message to your own number and see if it’s already working this time. If it still won’t send or receive, double-check your messaging inbox and outbox folders. Your device may not be able to send or receive further SMS or MMS messages if it has exceeded the message limit. In that case, deleting old and unwanted messages from your message folders is needed. If your message contains file attachment, make sure the file is not corrupted and the file size isn’t that huge. It usually take longer for the device to send file attachments of bigger file formats. In worst case scenarios, it may not be able to send the file at all. If necessary, you can compress the file first and then resend the message. If that won’t help either, then your last option would be to go for a master reset or seek further assistance from your network service provider/carrier.

Other options

If you’ve already exhausted all possible methods to solve the problem and get your Galaxy C7 Pro to send and receive MMS messages again but to no avail, contact your carrier or service provider. Doing so will help you verify the current status of your account and ensure that your number is not suspended and your SIM card is not faulty. Your account balance must also be up to date and your service must be free of any restrictions. If your account status and services are good but the problem continues, then you can ask your carrier to reset MMS on your account.
