Codes for free credit inquiries of almost all networks were rumored here and there, some worked most of them not, and some got blocked. Here we got another one for you, try it out.

Telenor:

This is the time when telenor got caught in its own vulnerability, simply use **444## instead of *444# for credit inquiry or dial 555 to hear your credit.

Ufone

*333*1*2*1#

Zong

*100# and *310#

But as described earlier, companies block these kinds of codes, as they get notified.

But at the moment it is totally free to check your Telenor, Ufone and Zong credit, using these code.
