You’ll need enough balance in the MBB number.

Ways to Recharge Your MBB Device

Master Number (USSD)

Dial *6767# → Choose “Recharge MBB Number” → follow prompts.

MBB Portal Recharge

Connect and visit 192.168.8.1.
Enter voucher code like *101*<15-digit code># to recharge.

My Zong App or Online Recharge Site

Use digital channels like an app, debit/credit card, or Zong’s online recharge portal.

Third-Party Apps / Agents

Pay via Easypaisa, OneLoad, FonePay, or your bank’s app. Then subscribe to bundles in My Zong App or portal.

How Bundle Renewal and Validity Work

Most bundles automatically renew if your MBB account has a balance.
For long-term plans (3, 6, 12 months), you pay upfront and get a fixed data allocation.
If a new bundle starts before the current one ends, the previous data may get replaced.
After expiry, you enter a grace period where only top-ups may work.

Check Remaining Data and Balance

Master Number: Dial *6767# → choose “Usage of MBB #” or “Balance of MBB #”. You’ll get details via SMS.
MBB Device Portal: Visit 192.168.8.1, go to Check Data Usage under Zong Services tab.
MBB SIM in Mobile: Insert the SIM into a phone and dial *102# or *222# for balance and data.

What are the Add-Ons for Extra Data in ZONG?

You can buy small add-on bundles if your data runs low.

Activate them using My Zong App, the portal interface, or USSD code *6363# via MBB Number—or through your Master Number with *6767#.
