How to fix Samsung Galaxy S7 Edge that can’t send SMS

Problem: Yesterday my 5-year old played with my phone, a Galaxy S7 Edge. Everything was working fine prior to that but after he played with it, I could no longer send text messages. I tried several times to send messages but to no avail. I’m thinking maybe some things were changed but as to what they are, I don’t know. Where should I look? Thanks.

Troubleshooting: Your device must be connected to the cellular network so that you can send and receive SMS or text messages. However, there are specific settings that have to be followed so that the handset can successfully send and receive messages. In your case, it’s the sending that has issues. This is what you’re going to do if your Galaxy S7 Edge cannot send SMS:

  1. Reboot your phone to make sure the firmware and all other services are running fine.
  2. Check the signal bars to see if your device is getting decent reception.
  3. Verify you still have enough credits to send texts by calling tech support.
  4. Verify your account is still in good standing.
  5. Check the Message Center Number and edit it if necessary.
  6. Reset your phone to bring it back to its factory defaults.
  7. If the problem persists after the reset, bring the phone to the shop.

By the way, the Message Center Number is necessary so that your phone can connect to your provider’s cellular network. If it’s changed or deleted, your phone can no longer send messages that’s why it’s necessary you verify it with the tech support.

As to the reset, it’s also necessary if all others fail to bring the phone back to its factory defaults or configuration that works. I suggest you backup your data and files and then reset your phone through the Recovery Mode:

  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. 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.
  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. 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.
  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.

I hope this helps.

How to fix Samsung Galaxy S7 Edge that can’t send MMS

Problem: I can send text messages just fine with my Galaxy S7 Edge but when I try to send pictures with my messages, it would fail. Just last month I was able to send a lot of pictures to my grandchildren but now I can’t. I am 65 years old and I don’t know how to fix it. Can you help me please?

Troubleshooting: When sending and receiving MMS messages or texts with pictures or files, mobile data is required. You are actually trying to send data that are larger in size and the cellular data your phone is connected to can no longer accommodate it. Here’s what you need to do to fix your Galaxy S7 Edge that can’t send MMS:

  1. Make sure Flight Mode is disabled.
  2. Verify mobile data is enabled on your phone.
  3. If mobile data is already enabled, check the APN Settings to see if your phone is setup properly.
  4. Call tech support if you don’t know the correct APN for your phone.
  5. If it’s provided by your current service provider, factory reset your device.

More often than not, this problem is caused by disabled mobile data or incorrect APN so steps 2 and 3 are very important. However, should you resort to factory reset, this is what you gotta do:

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings and then touch Backup and reset.
  3. Tap Factory data reset and touch Reset device.
  4. If you have screen lock feature turned on, enter your password or PIN.
  5. Touch Continue.
  6. Tap Delete all to confirm your action.

Galaxy S7 Edge can’t send messages when no signal is present

Problem: My phone (Samsung Galaxy S7 Edge) will not send messages when no signal is present but wifi is connected with full signal. Is there anyway I can fix this?
Solution: Hi! This kind of problem is not complicated but it depends on the device if what is causing the issue. It’s not that difficult to solve the problem as long as it is not a hardware issue. Actually, if the configuration of the device is changed and owners forgot to reset it back to default the problem occurs. We can’t determine what troubleshooting we can recommend resolving the problem since you did not specify what kind of “message” you are trying to send. Is it a social media message or text message or MMS?
Step 1: Check the Signal Strength of the Device
There are network providers allow their subscribers to use Wi-fi to send or receive MMS/SMS. We presume that you are sending a Short message services (SMS) or what we call text message using the Messaging app, then you should check the signal strength of your device to send or receive message successfully. As you mentioned, that there is no other signal displayed on the device but only the Wi-fi signal. The thing is, sending SMS should be connected to the network provider’s tower and have a signal strength to send.
Step 2: Reboot the Device
If this is the first time you’ve encountered the problem and you have no idea what is the issue is, then it might be a minor glitch of the device system or the hardware. It happens all the time, even this kind of devices are not that perfect, but it can be fixed easily by restarting the device.
Step 3: Check the Profile (Airplane mode)
This kind of mode in the device is used when the owners are always going on a trip, especially traveling by airplane. It disabled all the network connections like the wireless and connection from your network provider. Now if ever mode was enabled, you have to turn it off and choose the profile you are using. You can easily access it through notification panel or press and hold “Power key” for a few seconds and tap “Airplane mode” then go back to the main screen.
If none of it did not resolve the issue, we highly recommend calling your service provider about the coverage in your area since you are not seeing any signal bars on your device. It might be they are fixing some of their towers in the area or whatever their reason is they can tell you.
