How to fix SMSC Update Error in Android?

SMSC acronym Short Message Service Center (SMSC) is used to deliver the text messages where your phone needs to be configured to a valid SMS Service Center number. Otherwise, you won’t be able to send messages and get errors like “send failed”,  “Not delivered” and “not sent” etc.

It is quite easy to change the SMSC SMS Service Center number on the featured phones by going into SMS or messages option of your phone, but when it comes to the Android smartphones you may not be able to find the option to change the SMSC SMS Service centre as it comes pre-configured with the SIM of your service provider. There are changes when the pre-configured settings may not work all the time, and you need to change the default SMS service centre number.

How and where to find SMS Service centre settings in Android?

The SMS Service centre settings can be found within the Messages app’s setting, but in the newly launched Android smartphones you can open the SMS Service centre by dialling *#*#4636#*#* from the phone. As soon as you finish typing the short-code, the Testing window will pop up. On the testing page, tap on the “Phone information” option and in the “Phone information” you will be able to find “SMSC” where you will be able to set SMS service centre number.

To set the SMS Service centre number:

  1. Enter the default service centre number of your service provider
  2. Tap on the update button to save the settings
  3. Exit the Phone info page and test if it is working or not

You may get “update error” after tapping on the “Update” button; in this case, tap on the “Refresh” button and modify the existing service centre number without removing special characters such as single/ double quotes and commas.
