    I get this error – Your Registration information is incorrect. What to do ?

  11. Worked like a charm. Genuine & Risk free.
    My device was not properly connected the first time, so the registration code wasted. He gave me second code without any additional charges.
    Prompt communication on WhatsApp for all the queries.
