Recently i got an SMS from GLO network welcoming me into caller tune I thought it were a joke not until my buck was removed for unsolicited caller tune, I know many other subscribers would be having this problem of money deductions, then I am going to tell you how you can stop GLO caller tune on your sim card and thereby put stop to unnecessary deduction of your pretty dime.
If you are a victim of GLO tune then you can stop by sending DEREG to 131 and you get an SMS notifying you of the reception of your SMS and few seconds afterwards you get another SMS deregistering you from caller tunes. you can follow this simple step to stop the network from deducting your credit unecessarily
