Problem 1: Galaxy S7 can’t send SMS to all contacts

Hello. This is an issue with my Galaxy S7. All of my messages are failing to send. It is not the same issue from ~a month ago that was going around that was caused by an update where it says it failed on my end but still goes through. I’ve confirmed the receiving party is not getting the messages. All SMS messages are failing to send. I’ve confirmed the phone is on the most recent update. None of the troubleshooting I’ve found online has been successful. Any suggestions would be greatly appreciated and I’m happy to provide any additional information! Thank you. — Victor Yax

Solution: Hi Victor. There are a number of troubleshooting steps that must be done to identify where the problem is coming from. Since you didn’t share what exact troubleshooting steps you’ve already done, we’ll repeat them here for the benefit of others who may be experiencing similar trouble but hasn’t done anything yet.

If you’ve already tried all our suggestions, you should contact your carrier for more in-depth support. Keep in mind that there are only so much that you can do on your end. For all we know, the cause of the problem may be outside your device so there’s nothing much that you can do to start with.

Now, here are the troubleshooting steps that you can try:

Check if phone has a cellular signals

Poor network coverage can lead to all sorts of network-related activities in your phone such as voice calling, SMS, and MMS. if your phone has been receiving spotty network signals lately, this might be the reason for your problem.

Can you receive SMS/MMS or make/receive voice calls

If you can receive SMS but not send them, make sure that you check if the rest of related services like voice calling and mobile data are working. If they’ve stopped altogether as well, contact your carrier for a possible account problem.

Verify Message Center number is correct

An incorrect or missing Message Center Number (MCN) is often the main reason why a phone can receive SMS but unable to make outgoing texts. Be sure to check the device’s MCN by doing the following steps:

  1. Open the messaging app you’re using (we assume it’s the default stock Samsung Messages app).
  2. Tap More icon at the upper right hand side.
  3. Tap Settings.
  4. Tap More settings.
  5. Tap Text messages.
  6. Tap Message Center.
  7. Edit or add MCN.  

If you don’t know the correct message center number, contact your carrier to get it.

Wipe the cache and data of the messaging app

Sometimes, a messaging app bug can cause problems sending and receiving SMS as well so it’s a good idea to refresh its settings. Keep in mind that wiping the messaging app’s data will erase your messages. Be sure to create a backup first if you don’t want to lose any of them.

To wipe an app’s cache and data, follow these steps:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, look for the application and tap it.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

Do a factory reset

If nothing has improved at all at this point, you should consider wiping the phone clean to reset all software settings and remove possible software bugs. Below are the steps on what you need to do:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option Yes — delete all user data using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Ask support from your carrier

If a factory reset won’t fix the problem either, that means that the problem is potentially from the network side. Be sure to ask assistance from your service provider.

Problem 2: Galaxy S7 edge can’t send/receive SMS/MMS

I have recently been having an issue with my Samsung S7 edge and not receive text messages nor any pics or GIFs, my husband sent me a text and I didn’t even realize until I got home and he showed me his phone. And then I have several other people  trying to reach me because of a birthday party and i was not getting any messages. And I have checked to make sure that everything was turned on properly, have turned the phone off and on for a soft reset  and decided to try this avenue 1st before going to the phone company.

Anything you can do to assist me in this would be very helpful.

Also I am not able to send pics or GIF in my text messages if I do try and send then that entire message does not get sent. — Tonya

Solution: Hi Tonya. As we’ve mentioned above, if you’re having trouble in both sending and receiving SMS/MMS, that’s more likely an account- or network-problem. To ensure that it’s not a messaging app or operating system bug, be sure to wipe the cache and data of the messaging app, then do a factory reset. If both steps won’t resolve the issue, contact your carrier and let them figure out where the problem lies.

Also, if you’re in a GSM network, you can try to insert your SIM card to another compatible device to see if our suspicion that it’s an account or network issue is true. If you are in a CDMA network, just skip this suggestion.

Problem 3: Galaxy S7 keeps saying failed when sending SMS

I have a Samsung Galaxy S7. I updated it last night to Nougat and my texts say my messages have failed but I’m recording messages back as if it actually did send. It’s every number, Android and apple. I sent texts to see if they were received and they were. I reset my phone but nothing changed. — Felly

Solution: Hi Felly. This is a known bug and we are yet to receive confirmation from Samsung or from Google that it’s been addressed. From the best of our knowledge, there’s no effective solution for this problem yet so simply ignore the error you’re getting for now and simply assume that you’re successfully sending your SMS.

We will post a special article regarding this issue once we can confirm that this bug has been fixed.

Problem 4: Galaxy S7 not receiving some SMS

My phone is not receiving some text messages. It’s hard to say how many, but I have had at least three different people (using both iPhones and Androids) tell me- and even show me on their phone- that they sent me texts I never received. Just today I texted a coworker and thought she did not reply. However, it turns out she did reply, I just did not receive it. About three hours later she texted me again and that text I did receive. I have not had any issues sending texts. — Amanda Harris

Solution: Hi Amanda. If your issue occurs intermittently, the most likely cause is on the network side but since we don’t know the full history of your device, there’s a chance that it maybe caused by something you’ve added such as an app. To see if that’s the case, we suggest that you let your phone run in safe mode for a few days straight. This will give you enough time to notice any difference. While in safe mode, all third party apps and services will be blocked so if the issue messaging works as expected, that’s a clear indication that a third party app is to blame. To restart your phone to safe mode, follow these steps:

  1. Turn your Galaxy S7 off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. Observe the phone for a few days.

Remember, safe mode is not a solution but a means to help you identify whether an app is causing the problem or not. If you think a third party app is causing a problem, you must uninstall apps one by one until the issue has been eliminated.

If the problem remains though, you should talk to your carrier and let them determine a solution for the issue.
