How to troubleshoot Samsung Galaxy S7 text messaging issues (SMS & MMS)

The text messaging service is one of the very basic feature of a phone. Needless to say, your #Samsung Galaxy S7 (#GalaxyS7) should be able to transmit small amount of data over cellular network without having a problem provided the device is properly provisioned to receive services from your service provider.


But the thing is many users have been complaining about not being able to send and receive SMS messages as well as MMS for some reason. We’ll try to look into this problem a little closer as it is one of the most common issues you may encounter if you own a phone.

Troubleshooting SMS & MMS Issues with Galaxy S7

In this guide, I will walk you through in ruling out every possible cause why your phone can’t send and/or receive text messages or can’t transmit picture messages or MMS.

Step 1: Check the signal bars

It must be the first thing you should check because you don’t need to do anything in your phone; you just have to look at the status bar to see if your device is receiving service from your service provider. If the signal bars are empty, then you don’t have service. If there is only 1 bar or two, then it’s either there’s something wrong with your phone’s antenna or it’s a network problem. But either way, you have to contact your provider because, in the first place, your phone is brand new and probably just a few days old and secondly, if it’s a network issue, there’s nothing you can do about it.

Step 2: Look for the airplane icon

If flight mode is enabled, the phone won’t be able to connect to any wireless network. Just like step 1, you just have to look at the status bar to see if there’s an airplane icon. If there is, then turn it off so the phone can get wireless services. Press and hold the power key for a few seconds, then toggle the flight mode from On to Off.

Step 3: Now, reboot your phone

A simple reboot can fix a lot of minor problems. So, if the signal bars indicate your device is getting excellent service or if there’s no airplane icon on the status bar, then it’s time you tried rebooting your phone.

During initialization or boot up, the phone will try to reconnect to the network and if successful, the connection would be fresh and more stable and it might just fix the issue.

Step 4: If you can’t send an SMS, check the Message Center Number

The Message Center Number is very important in sending text message. It’s a series of numbers that looks like any ordinary phone number used so that your messages will be sent to the base station or tower your phone is getting signal from. From there, the message will be sorted out and delivered to the recipient. So, basically, without it or if it has been edited and reflects an incorrect series, the device won’t be able to send messages.

Step 5: If you can’t receive text messages, check if there’s enough storage

I understand if you react to this considering your phone is still new and probably you still haven’t used half of the storage. But there have been a lot of issues like this before that points to the storage being the culprit. If you’re the kind of user that takes a lot of photos and videos, save a lot of movies you can watch on the go, or transferred all your files and documents from your previous phone, then try checking the storage. If your phone is running low in storage space, try to free up some by moving your files to your SD card or computer.

Step 6: If you can’t send and receive SMS, try making a call

This step rules out the possibility that it’s a coverage issue as well as a problem with your account. But either you can make an outgoing call or not, you still need to call your provider because it can be an issue with your account. Account-related issues can’t be fixed by subscribers unless you just have to pay some bills to enable your service back.

Step 7: If you can’t send and receive MMS or picture messages

Check the mobile data immediately! It must be turned on so that you can send and receive MMS. If it’s already enabled but you still can’t send/receive MMS, then check the APN setting. The APN or Access Point Name is actually a set of data used so your phone can connect to your provider’s network. If there’s one incorrect character, letter or number, your device can’t connect to the network.

You may google your provider’s APN and see if it conforms with one that’s on your phone but I suggest you call tech support (your provider’s of course) and ask for it just to be sure you got the correct one.

Step 8: If you can’t send group text messages

Just like the previous step, make sure mobile data is turned on and then check the APN because group text is considered MMS. The same thing goes for text messages with attached pictures or files, SMS with emojis and other special characters.

If all these failed, call your service provider NOT Samsung because your carrier will be able to help you better. There hasn’t been any reports of major antenna or reception issues so if you have this issue, it’s probably a network issue.

  1. My theory about failure to send MMS messages is the carrier’s bandwidth is not up to the volume of user traffic. After a certain threshold is reached (wait time), the message you are attempting to send basically times out and the message fails.

  2. And I’d like to add that calling tech support is actually more of a joke, if you will. Not that nobody there can’t ever help you, but calling in to call centers overseas, as your call centers are located, then having to wait on hold; then trying to explain while the rep asks you to reiterate your issue, not once, but several times over; then having to decipher a potential dialect that you might not easily comprehend jsut for that reason, but ignore and pretend you heard asfter the 3rd attempt so to not be rude; having any given rep (because they don’t have physical access to your phone) go through everything that you just did while you already know that didn’t work when you just did it, while still needing to do it to apease the rep and still, nothing improves (or remains improved) is a real pain in the toosh. Then the rep wids it up and directs you to the repair shop store, which you wanted to avoid because you have to take a number or make an appointment and wait some more. Seriously, why is this even happening? It woul be nice to know to fix these issue and not need to go through all of the hassle, only to have the issue return at a later time.

  3. This happens to me with my Sprint SGS7 Edge, but not on a daily basis, though it does happen somewhat frequently. Text message take all day tocome in, sometimes a couple of days. I’ve learned this over time when my adult children have taken screenshots of dates, times and their messages sent to me; then I see clearly that it’s taken six, eight, ten hours or days for their same texts to come in. Both types, with photo’s and not. It’s random.

    I reboot my phone every day or two. I do not have call reject/blocking enabled (I believe I can only do that per number calling in) but when I do receive my missing texts, usually hours later, I never had that number blocked, anyway.

    I am not having issues with bluetooth, nor do I have airplane mode turned on. When this delay happens, I’ve figured out that my phone, also, cannot receive calls – or won’t ring in – as the calls go straight to voicemail.

    Last night I tried to trigger my phone to ring in by calling out, first after my husband tried calling in and his call went right to my voicemail. So I dialed his number, it rang, and then he called me back and his phone call finally rang in on my phone. At that very same time, I received over 20 delayed text and also picture messages.

    I became aware of this issue, again, when I returned home and my kids asked why I had been “ignoring” thier calls and texts. I had no missed calls, no voicemails and no texts until a few hours later, when I had (at least this is what I think I did) “triggered” my phone to receive a call. Then I received back-to-back inbound messages and notices of voice messages.

    I’ve noticed this has happened on at least 10 other days since this past October but, as far as I can tell, it doesn’t happen daily.

    This also happened on my previous Samsung Galaxy phone, one of the Note series, which was also with Sprint. It does get annoying and, now that I am very aware of this happening, I am concerned over one day missing a call I’d hate to miss.

  4. Hey guys i have a samsung s7 sprint phone, I’m in canada with a sasktel sim in it and i cant send or receive mms messages. Im running out of things to do to this phone. I have changed vpn to my carrier hard reset everything, its making me crazy .

  5. What is this other than a waste of time? 95% of people will have already done what you wasted time typing up. Why else would I search for the issue? It’s 2016, not 2007. How about some real advice like calling your cell provider to reset connection with the cell tower. Despite what you may think, putting your phone in airplane mode or restarting your phone does not so a proper reset from the tower.

    But that probably won’t fix your problem. Chances are, you have ATT. I have had ATT for 7 years and have always had MMS issues. Especially with group texts. I’ve had iPhones, Nexus phones, all Samsung phones, and a lumia 950 (before going back to my s7) and guess what? All had issues with MMS. I’ve also had Verizon ans T-Mobile and never had MMS issues. My mom and dad have sprint and also never have MMS issues.
