I understand you may have already fixed a lot of issues like this but if you can just point me to a post you’ve previously published or give me step by step solution, then that would be great. Thank you!

To successfully send or receive a text messages, your device must have at least one signal bar or more. You can see the signal bar at the notification panel at the top of the screen, try to check if you have a signal. Or you can manually check the available network in the area.

To manually check the network, follow this steps: Go to Apps menu > Settings > Mobile networks > Network mode > Select the available network setting. After selecting a network, you should try sending a text message and let them reply if your device is able to do it.

Step 2: Your Location Must Be Covered With Your Service Provider

Make sure that the service provider you are subscribe with is covering your location and have enough network towers in the area. It would be useless if the services offered are only limited and covered some portion of your location, which means there are only certain areas in your house to have signal or in a county. However, if most of your neighbors are using the same service provider that you have, then there might be something wrong with your service. You can also try to manually select a network available in the area.

To manually select a network, do these steps: Go to Apps menu > Settings > Mobile networks > Network operators > Choose Search network > Select your network provider > Go back to Home screen. Then, check your device if there is signal displayed.

Step 3: Check Your Available Credits

You can check your available credits if you are on a limited subscription. There are service providers that offers their members a limited credits depending on their budget. To check for possible problem and in case if you are subscribe to unlimited service then it is best to call your service provider regarding the issue because their might be something wrong with their services in your area.

Step 4: You Can Try Using A Different Messaging App

This issue occurs sometimes after a software update and causes some problem to other apps, in this case the Messaging app. You can install a different messaging app from Google Store, but this is only  temporary just to determine if there is a problem with your default Messaging app. Then, you can try sending and receiving a text message, if ever you are able to send and receive SMS or text message using the installed app, you can go ahead and try clearing the cache and data of the default Messaging app.

To clear cache and data, follow these steps: Go to Apps menu > Settings > App Manager > Select the default Messaging App > Clear cache > Clear data. After doing so, you will be able to send and receive a text message, then uninstall the third party messaging app you recently installed.

Step 5: Have Your Message Center Number Checked/Corrected

The last thing that you should do after you follow all the troubleshooting steps above is to check your message center number. This number is very important and pre-set by your network provider to deliver your text message to its destination or to someone you want to communicate with. If this number was accidentally changed or deleted, then your text message is going nowhere, unless you will change it manually.

You can refer below for the steps to manually change your network provider’s center number, the default numbers are included above also.

How to fix Galaxy S6 Edge that can no longer send MMS or picture messages after an update

Problem: Hello guys. I am hoping you can give me some pointers on how to fix my phone. It’s a Galaxy S6 Edge, it’s almost a year since I bought it.

Unlike sending a text message, you need to turn on your device mobile data network because you are sending a picture and it is larger in size compared to SMS or short messages.

You have to make sure that you are in a location that has a strong signal strength (preferably 3-5 signal bars). There are a lot of owners assuming that they can send picture message anywhere they want. To check the signal strength of your device, you just have to look at your device signal strength icon located top-right side beside the battery level.

Step 2: Data Network Must Be Active

After checking your network signal strength, activate your data network through the notification panel and tap the mobile data network icon. To send MMS is like sending emoticons in social media using the mobile data network or internet. You will know if the mobile data network is activated because there is another signal icon beside your network signal bar but it has two arrows pointing up and down.

Step 3: Make Sure That You Have Enough Credits

The problem sometimes is not always on the update, there are rare cases that the owners forgot to check their credits to be able to send or receive an MMS or use other services. There are network providers allow their subscribers to use Wifi to send or receive MMS or SMS. However, in your case, your network provider might not authorise you from using Wifi, but if your authorized then you have no problem sending or receiving, only when you’re using mobile data. To know the services of your service provider offered, you can simply call them for inquiries.

To successfully send and receive a text message or picture message your message center number must be correct. Since this problem started after an update, there are possibilities that the message center number was not included in the update and causing your device to unable to send and receive MMS or picture message. Every network service provider regardless what devices the owners are using have different and default message center number. To make this simpler, you can follow the steps below how to check your message center number:

  1. Assuming you are on the main screen
  2. Open your device’s keypad, tap Phone icon
