SMSC Not Set Correctly

An ofttimes overlooked problem is an incorrectly set SMSC number. The SMSC is responsible for sending SMS messages from your device.

How SMSC works.

There are numerous ways your SMSC may accept 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 thought if y'all don't know exactly what they're doing.

Solution one: Setting SMSC Through Secret Phone Card

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

1. Bring up your telephone dialer.
2. Enter the number *#*#4636#*#*
3. A menu will launch. Choose "Phone Data".

7. After yous have entered the SMSC number, tap 'Update'.

If you do not know your carrier'southward SMSC, you can try consulting a list of global SMSC numbers for the almost popular carries past country. However, these lists can be outdated – it may exist best to contact your carrier to get the correct SMSC number.

If you receive 'Update error ' when manually adding the SMSC, many users recommend converting the SMSC number to PDU format. This did not piece of work for me personally, but I'one thousand listing the steps in case information technology works for you.

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

   

   SMSC to PDU conversion.

3. Erase any text is in the fields for "Receiver" and the message box higher up the "Convert" button.
4. Enter your SMSC number in the SMSC field and click convert.
5. The right side box will produce a cord of letters and numbers. Y'all demand the kickoff sixteen digits on the ii^nd line (highlighted in our screenshot).
6. Enter this PDU number into the SMSC field, and try striking "Update" again. If information technology still fails, try calculation a + sign to the beginning of the PDU number. If it yet fails, try the next method.

Solution 2: Setting SMSC in Default Messaging App

Many of u.s.a. similar to download culling texting apps than the stock one that comes with our devices. Apps like Textra, Chomp, EvolveSMS, and fifty-fifty the SMS feature in Facebook Messenger seem like fancier alternatives to the stock app.

If you're a root user who likes to debloat your telephone, you probably also disabled the default SMS app. The funny thing is, the default SMS app usually has an option for setting the SMSC number, whereas most third-party SMS apps do non. This is typical because the default SMS app is a /system app with privileges to alter the SMSC, whereas the third-political party apps are not.

If whatever of this sounds like your scenario, attempt this.

Setting SMSC in default SMS app.

1. Get to Settings > Apps, find your stock SMS app (the i that came pre-installed on your phone).
2. Tap it, and make certain it'due south not disabled. If it is, enable it.
3. Now launch the SMS app, and look for the SMSC setting. In my device, it was located in the app's Settings > SMS settings > SMS service center.
4. Enter your SMSC, salve it, and attempt to send a text bulletin.

If information technology gets sent, the problem is solved! Y'all can now switch back to any SMS app you prefer, merely exercise not disable the default SMS app. The third-party apps may actually rely on the default SMS app's configuration.

Solution 3: Resetting the SMSC in Another Phone

If zero has worked for y'all so far, some people study they are able to fix the issue past setting the SMSC in a unlike telephone, 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 different phone. Even an quondam Nokia should work for this.
2. Find the SMS / SMSC settings on the other phone, and set it properly. It's important to remember that SMSC settings exercise not actually go saved to a telephone, they go saved to the SIM bill of fare itself. So the correct SMSC configuration will comport over when you lot switch it dorsum to your regular telephone.

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

"I put my sim card in old Nokia 6120 C, then this time I change the SMS Configuration. I renamed the championship used at that place. I Change from "Pusat Pesan SMS" to Message Center. This time it succeeded.".
