Related to my Imei no

Posting sensitive information like your serial number and IMEI is not advisable.

All we can suggest is go here and check your warranty:

Check Your Service and Support Coverage - Apple Support

Not a good idea to post private info (IMEI) In a public forum. You can use this link to check for yourself: https://checkcoverage.apple.com/
