How to Block Unwanted SMS & Calls in Pakistan [Guide]

A phone is a personal device and your number is your identity. When some unknown individual disturbs you with a call or SMS you feel like somebody has barged in on your privacy.

As phone usage has increased in the country, so has the volume of spam messages and unneeded calls as well. Marketers send bulk SMS messages to forward advertisements and promotions. People who make prank calls or tease people over the phone have also increased with time.

The best way to deal with this is to block these callers and spammers. Thankfully all operators offer SMS and call blocking services.

We have listed them all below for your convenience.

Note: ‘0333xxxxxxx’ at the below packages refers to any mobile phone number you need to block/unblock.
