Good afternoon preetfromsecunderabad,
Welcome to the Apple Support Communities!
I understand you are seeing an "error in application" message. How is this message showing up? Are you in a particular app when you see it? Is it a Safari pop-up or a text message from your wireless carrier?
If the error is a text message from your wireless carrier, contact them to determine why you are receiving the message.
You may need to update your carrier settings or replace your SIM card.
Update your carrier settings on your iPhone or iPad
Remove or switch the SIM card in your iPhone or iPad
If you are in a specific application when the message appears, force quit the application, restart your iPhone and try again. If the issue persists, close all of your apps and restart the iPhone. Then make a note of which app you are in when the error message appears.
How to force an app to close on your iPhone, iPad, or iPod touch
If the error message is appearing in Safari, try clearing Safari history and website data:
Settings > Safari > Clear History and Website Data
Settings > Safari > Advanced > Website Data > Remove all Website Data
Take care.
