Texting issues are among the most commonly reported issues with the new Samsung Galaxy S7 Edge or any Android phone for that matter. Being one of the basic services, it’s inevitable that sometimes things may happen and disrupt your phone’s normal operation.

The thing with text messaging problems is that, more often than not, the network or your service provider has something to do with it and in this case, you are left at the mercy of the tech support. Honestly, if the problem is with your provider, there’s not much you can do about it except report the problem so the company can take actions or, at the very least, the issue will be documented.

Troubleshooting is the key to knowing whether the problem is with your phone or with the network and while I understand some of may hate the idea of meddling some settings in your phone, it’s necessary so you would know what to do. You might save yourself from waiting for hours at the shop while the device is being checked by a technician without the guarantee of a fix. So, I suggest you through the troubleshooting procedures below before you decide to send the phone in for checkup or repair.

But before anything else, if you have other issues with your device, visit and browse through our S7 Edge troubleshooting page where we list every problem we address each week. Find issues that are similar or related to yours and use the solutions and/or troubleshooting procedures we recommended. In case you need further assistance, feel free to contact us by completing our Android problems questionnaire. Make sure you include as much details as possible so it would be easier for us to help you. The more information you provide, the more accurate our solutions are.

New Galaxy S7 Edge can’t send / receive texts

We actually did receive a lot of complaints about some S7 Edge units that can’t send and/or receive text messages out of the box. I included the actual message from our reader below just to show you how this problem occurs or happens:

Hi guys! I just got my Galaxy S7 Edge and I already put it the SIM card and it’s actually receiving signal from the tower but it can’t send / receive text messages. Do I have to do something before I can use it to send SMS? Help me please.

With this kind of problem, there’s one thing you need to check immediately–the signal. If the phone is receiving signal from the tower, just like what our reader said, then you’ve already ruled out at least two possibilities–that the SIM card mounted incorrectly and the phone can’t recognize it.

Assuming the phone is receiving signal from the tower, then the next thing you have to do is call your service provider. The phone is working fine and the SIM card is mounted properly and recognized by the device. These are the things you need to verify and if all else fails, your provider can provide you with answers and solutions. There’s a chance it has something to do with your account or a provisioning issue. The phone as well as the SIM card attached to it has be registered in the network to be able to receive and use the service.

Phone can’t receive text messages but can send just fine

At least, with this issue, you don’t have to worry about the signal or reception, your account, and your SIM card. If you can send a text message successfully, it means you have enough credit, your phone is getting good reception, there are no bars with your account and your SIM card is properly mounted and detected by your phone.

Since you’re phone is still new, I don’t think the problem has something to do with the storage. But if it happens that you’ve already used up almost all of your phone’s internal storage, then just free up some space and you will fix this problem.

Having ruled out other possibilities though, I think the problem might be caused by an app glitch. Yes, this problem happens all the time and many reported that it just occurred without apparent reason. That said, here are the things you should do:

  • Reboot your phone as it is effective in fixing minor firmware and app issues.
  • Send a text message to your own number to verify if you can receive it.
  • Clear the cache and data of the Messages app.

Clearing App Cache & Data

  • From the Home screen, tap the Apps icon.
  • Find and tap on Settings.
  • Touch Applications and then Application manager.
  1. Swipe to ALL tab.
  2. Find and touch Messages.
  3. Touch the Force Close button first.
  4. Then, tap Storage.
  5. Tap Clear cache and then Clear data, Delete.

Galaxy S7 Edge can’t send text messages but can receive

This problem is basically the opposite of the second problem I cited above and while many think both issues are identical, well, they’re not. This one has something to do with the setting, most of the time, while the previous one has something to do with the app.

If the issue occurred without apparent reason, then there’s a chance it’s just a minor and temporary issue, which can often be fixed by reboot. So, do restart your phone first before doing any troubleshooting.

After the reboot and your phone still can’t send a text message, then the problem must have something to do with the Message Center Number. I am sure you don’t know what the correct number is so you better call your service provider and have the rep give you the correct number and then ask him/her to walk you through in verifying whether your phone got the correct Center Number or not.

Phone can’t send / receive text messages without apparent reason

Firmware issues may also cause this kind of problem, however, it’s not easy to determine what the cause is. So, if your phone suddenly can’t send or receive text messages, there are things you need to do depending on the situation.

If the problem manifests after a firmware update, it could just some corrupt caches. For this, all you got to do is delete the system cache:

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge 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 cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

If the problem occurred after installing some apps, then boot your phone in safe mode and try to see if it can send and receive SMS while all third-party apps are disabled because if so, there’s an app you installed that’s causing the problem. Find it and uninstall it but here’s how you boot your device in safe mode:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 EDGE’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

If deleting the system cache and booting in safe mode didn’t yield any results, then you have no other options but to do the master reset:

  1. Backup your data.
  2. Remove your Google account.
  3. Disengage screen lock.
  4. Turn off your Samsung Galaxy S7 Edge.
  5. Press and then hold the Home and Volume UP keys, then press and hold the Power key.

NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.

  1. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  2. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

  1. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  2. Once highlighted, you may press the Power key to select it.
  3. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  4. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  5. The phone will now reboot longer than usual.

Now, before I end this post, here are some problems from our readers that I would like to answer:

Q: “I can only use 160 characters in my texts. It just freezes. If it split up the text, it wouldn’t be so annoying. I have to delete half of a sentence, send and continue with the rest of my message. I checked at my sprint store. They said there isn’t any fix. Do you have a solution?

A: That’s the global standard when it comes to SMS, that’s why it’s called Short Message Service. Technology may have already improved and carriers already have their own messaging apps to transmit messages with larger size. However, they’re often transmitted via mobile network. The point is, if you don’t like the idea of having just 160 characters in your message, then use the enhanced messaging system your provider is offering because there’s nothing we can do about the SMS character limit. There’s no fix because there isn’t a problem.

Q: “I always switch my phone off at night and having just upgraded to the S7 Edge have noticed that any text messages received whilst the phone is switched off, display the time I actually switched on my phone rather than the time that they were sent… I have the date and time and zone set to automatic… And remember having this problem when I first had the Samsung Note, however there was an app available then to fix it… Can you help please? Here’s hoping…Many thanks.

A: Sadly, that’s how it works even now. From what I understand about it, your phone gets the timestamp locally (phone’s time) or from the network and considering the size of the data allowed to be transmitted over cellular network, I think it’s difficult to include the time and date information from other phones.

There’s an app called SMS Sent Time (search for it at the Play Store) that allows you to display the message was actually sent from another phone. Try to see if it can help you.

Q: “I have had my Galaxy S7 Edge for approximately one month and have had no issues.  I installed application for the Oculus and operating system yesterday and used it off and on for approximately 3 hours.  Today I cannot send texts to any iPhone users or group texts.  I can still send texts to other android users though as long as its a single person at a time.  Called tech support at T-Mobile and while on the phone with them they checked the “message center” phone number in my phone.  While on the phone with tech support I was able to send a group text and a text to an iPhone user.  Tech support said they did something with the “message center” number on their end.  I then got off the phone with tech support and immediately sent another text to the same iPhone user I had just text while on the phone with tech support and the text would not go through.  Neither will group texts.  I uninstalled all apps that have to do with the Oculus and still not able to text.  I don’t even know if the problem if from the Oculus installation but that was the only thing newly installed on my phone.

A: It appears to me like you were trying to send MMS instead of the normal SMS. Nowadays, text messages with a special character like emoji are already considered “multimedia” messages. In this case, mobile data is necessary. It looks like the app you installed or the recent firmware update messed up your phone’s APN settings but before checking the APN, verify if mobile data is enabled and if so, then proceed to checking the APN. You may call tech support again and ask for the correct APN for your phone and have the rep walk you through in setting it up.

Q: “Using the default texting app on my S7 edge iPhones will not receive certain messages. How this occurs is I will be texting the same number different sized messages with emoticons some messages she will receive other she will not. There is no pattern as to what messages she receives some short messages will not send some long messages will not send, some long messages with emoticons wont send but if i add more emoticons it will send. Have tried with other iPhones and have had the same problems with the same texts but messages will send straight away to android phones.

A: Either the mobile data on your phone isn’t enabled or the mobile data in her phone is also disabled. Verify your phone is capable of sending MMS by turning on mobile data. If it’s already enabled, then check the APN to know if it’s the correct one (you may call your provider for this) and it is, then the problem is with her phone, not yours.
