airtel sms not sending

One of my friends asked:

Why I am not able to send text messages from my Airtel Sim? Whenever I send text messages and close the app. After sometime it say “Message sending failed” so when I checked, message wasn’t sent and it was having a red refresh button before it and when I tap it, it does not work? Currently it is happening with me persistantly! What’s the solution for this?

Text messaging is one of the oldest forms of communication. But still, text messaging is a secure and reliable method for communication. and verification too.

Even though the messaging features can work very well even without the network connection, sometimes the messaging feature doesn’t work properly.

Although text messaging is very good for communication, sometimes it may give you errors related to sending text messages. So, to fix the issue that the text message failed to send from the Airtel sim you can try the tips listed below in the article.

Solutions to Airtel SMS not sending problem:

1. Top-up Recharge:

Most of the time the problem is related to top-up. A low balance on your Airtel number can cause this problem. Thus to solve this issue firstly check your talk time balance by dialling *123#. If it is low then recharge with at least 10 Rs. In my case, it worked only once.

So my suggestion is that you should call Airtel customer care service which will definitely guide the minimum recharge plan that can activate your sim card validity and indirectly the SMS service of your sim. So I recharged with that and my SMS sending issue was solved.

So try recharging your sim card After recharging check again if the messages are sending or not, if not then try the next solution.

Sometimes clearing cache and force stop may not work if your phone has internal misconfiguration thus to solve this error just simply restart your smartphone.

6. Change Airtel SMS Center Number in Android & iOS

An SMSC number is responsible for handling the SMS operations of a wireless network. When an SMS message is sent from a mobile phone, it will reach an SMS center first. The SMS center then forwards the SMS message towards the destination.

Thus if you have set the wrong SMSC number then you will get of SMS not sent. thus to solve this error you should Update your SMSC number.

There is a different procedure for Android and iOS so follow them according to your device system.

Android

  1. Dial – *#*#4636#*#* on Keypad.
  2. It will automatically open ‘Testing’ settings. Now if you have two sims in your android phone then choose accordingly. In my case, I opened ‘Phone information1’.
  3. Now scroll down and try to find the ‘SMSC’ option and type your network operator’s SMSC number of your area and tap Update. I am from maharashtra thats why I typed Maharashtra’s SMSC number.
