All you have to do is to call your respective Customer helpline and reach your Customer Service Representative (CSR). Ask your CSR to ban all those promotional SMS from their company to be received on your number. Here is the list of Customer Helpline numbers just in case you don’t remember them. Mobilink (111), Ufone (333), Zong (310), Warid (321) and Telenor (345).
As I have inquired about the same with Ufone Help Desk after some in depth talking he revealed the trick of blocking these sms. The CSR gave me the number ‘ 25625 ‘ (with Zero Call Charges) to call to and have the Ufone and third-party Promotional messages (Spam) turned off.
Its a computerized service and after you make the request formally by calling on the given number, the computer would tell you that your request will take upto 7 days to complete.

I hope there will be some PTA rules and guidelines that exist for these Operator(s) promotional and their third-party promotional (sponsors) messages, as according to the Call Center Agent ‘ ALL Ufone Customers are subscribed to these promotional alerts ‘ i.e. without their intent !
Now just call them and get relieved from constant vibrations and SMS beeps that used to disturb your daily routines. Now you don’t have to get notified about latest “exciting” offers and details of “Lucky draws” by your service provider. Keep on using Mobile services without much irritation from your mobile company.
In worst case scenario, if cellular operator does not pay attention to your request, then you have a door open. Just send your complaint to Pakistan Telecommunication Authority (PTA) by calling them on 051-9225325 or send an email at firstname.lastname@example.org
