Hi Harsh4687,
I have same issue, Airtel guys are saying the number is changed to my airtel number but which is not reflected in account details. due to this i am unable to watch xtream content. Now My account also suspended, I dont recharge to watch DTH channels on regular basis.
Finally i am able to watch the xtream content by Modifying the phone number in the two files named as account details data text file in downloads folder. You can use any file manager to edit the two files. Then go to apps, clear the data of xtream app, then restart the box. the account details in settings remaining same and dont bother about the account details, but you able to watch the xtream content.
Let me know if anyone need help to edit the text files.
Best regards,
Ravi.
