Hello @MehediH_2094658 sorry to hear that you have a problem.
there are two reasons why we cannot help directly.
1. We are Community Forum members like you and not generally Smarty staff so we cannot look at your account.
2. You have not really given enough detail about the problem e.g. Is there absolutely no SMS service? Is it just Contacts on your phone? When did you activate your sim? Does calling and data work?
