Using unauthorized .tnl files from forums or social media can pose security risks:

Unverified VPN configurations can potentially intercept your data or slow down your connection significantly.

While "tnl" files are community-made and often unreliable, Zong 4G provides several official, secure ways to get WhatsApp data:

For Rs. 250 (incl. tax), users can get 4GB or 5GB of dedicated WhatsApp data by dialing *3998# .

You can check your remaining WhatsApp data balance at any time by dialing *102# . Risks of Using Third-Party Files

Zong frequently offers free, unlimited access to WhatsApp features (video, voice, and chat) for all prepaid customers. You can typically activate this by dialing *247# .

Ensure you have the official WhatsApp app downloaded from the Google Play Store or Apple App Store before attempting any configuration.

These files often expire within a few days or stop working if Zong updates its security.
