Facebook Messenger Failed to Send Message Please Try Again

There are numerous reasons why SMS texts in Android can fail to send (or exist received, but this article will focus on the failure to send). If yous cannot receive SMS texts, yous tin cheque out Phone Not Receiving Texts.

However, if you can receive texts just fine, but your texts always fail to ship, the consequence virtually likely lies with your SMSC number. This is not a hardware or software effect; factory resetting your telephone volition accomplish nil. This is considering the SMSC number is actually written to your SIM card, not on your device.

In this article, we will show several methods for fixing the SMSC number on your Android device.

SMSC Not Gear up Correctly

An often overlooked problem is an incorrectly fix SMSC number. The SMSC is responsible for sending SMS messages from your device. When y'all send an SMS message, it gets forwarded to the SMSC, which so sends it to the destination. Your SIM carrier is responsible for maintaining the SMSC network.

If you accept an incorrectly fix SMSC, you will still receive text letters because the other person'due south SMSC is forwarding the messages direct to your SIM number. But your text letters fail to send because your texts are not reaching your carrier's SMSC. Meet this simplified graph:

How SMSC works.

At that place are numerous ways your SMSC may have been inadvertently incorrectly configured or outright deleted. In this my personal experience, my SMSC was erased when I downloaded a root app that would supposedly enable VoLTE. Lesson learned – apps that "tweak" your telephony settings are probably a bad idea if you don't know exactly what they're doing.

Solution 1: Setting SMSC Through Secret Telephone Menu

This method works for about – it is the most commonly recommended method by all experts. Personally, information technology did not work for me. When trying to add my carrier's SMSC number to the appropriate field, the menu would requite a "failed" error. This was whether or not I converted the SMSC to PDU. Then if this method also fails for you, try the side by side one.

1. Bring upwardly your phone dialer.
2. Enter the number *#*#4636#*#*
3. A menu will launch. Choose "Phone Information".
4. Roll downward to SMSC, and tap 'Refresh'. This should automatically endeavour to correctly ready your SMSC number.
5. If it fails ('Refresh fault'), you tin can try manually setting it.

   

   SMSC refresh error.

6. In the field for SMSC, enter your carrier'due south SMSC number.
7. After you lot accept entered the SMSC number, tap 'Update'.

If you practice not know your carrier's SMSC, you lot tin can try consulting a list of global SMSC numbers for the almost popular carries by country. Yet, these lists can be outdated – information technology may be best to contact your carrier to go the correct SMSC number.

If you receive 'Update error ' when manually calculation the SMSC, many users recommend converting the SMSC number to PDU format. This did non piece of work for me personally, but I'one thousand list the steps in case information technology works for you.

1. Go to this website – Online PDU Encoder and Decoder.
2. Roll down to the bottom of the page, where it has a field for SMSC to be converted.

3. Erase whatever text is in the fields for "Receiver" and the message box above the "Catechumen" button.
4. Enter your SMSC number in the SMSC field and click convert.
5. The correct side box will produce a string of letters and numbers. You demand the first 16 digits on the 2^nd line (highlighted in our screenshot).
6. Enter this PDU number into the SMSC field, and try hitting "Update" again. If it still fails, try adding a + sign to the beginning of the PDU number. If it all the same fails, try the next method.

Solution ii: Setting SMSC in Default Messaging App

Many of us like to download alternative texting apps than the stock one that comes with our devices. Apps like Textra, Chomp, EvolveSMS, and even the SMS feature in Facebook Messenger seem similar fancier alternatives to the stock app.

If you're a root user who likes to debloat your phone, you lot probably also disabled the default SMS app. The funny thing is, the default SMS app usually has an selection for setting the SMSC number, whereas most third-party SMS apps practise non. This is typical considering the default SMS app is a /system app with privileges to change the SMSC, whereas the 3rd-party apps are not.

If any of this sounds like your scenario, try this.

Setting SMSC in default SMS app.

1. Go to Settings > Apps, notice your stock SMS app (the one that came pre-installed on your phone).
2. Tap it, and brand sure it's not disabled. If information technology is, enable it.
3. Now launch the SMS app, and expect for the SMSC setting. In my device, it was located in the app'southward Settings > SMS settings > SMS service center.
4. Enter your SMSC, save it, and try to transport a text message.

If information technology gets sent, the problem is solved! You tin at present switch dorsum to any SMS app you prefer, merely do not disable the default SMS app. The third-political party apps may actually rely on the default SMS app'south configuration.

Solution 3: Resetting the SMSC in Another Phone

If nothing has worked for you then far, some people written report they are able to set the consequence by setting the SMSC in a different phone, then putting the SIM card back in the one with issues.

1. Pull the SIM card out of your device, and stick information technology on a unlike phone. Even an old Nokia should work for this.
2. Find the SMS / SMSC settings on the other phone, and prepare it properly. Information technology's important to think that SMSC settings practise not actually get saved to a telephone, they get saved to the SIM card itself. So the right SMSC configuration volition carry over when you switch it back to your regular telephone.

One internet user reported this method did not work until they did an additional footstep:

"I put my sim card in old Nokia 6120 C, then this time I change the SMS Configuration. I renamed the title used there. I Change from "Pusat Pesan SMS" to Bulletin Heart. This time it succeeded.".
