Tips for Managing Multiple Zong SIMs
Label Your SIMs
If you’ve got multiple SIM cards at home, label each one with the number and its use: “Zong Data”, “Work SIM”, “WhatsApp only”, etc. This avoids confusion.
Use Dual-SIM Phones Smartly
Modern smartphones let you name each SIM. Set one as “Zong” and the other as “Jazz” or “Telenor”. Assign a default SIM for internet and another for calls.
Store SIM Info Digitally
Save each SIM’s number, CNIC link, and PUK code in a secure app like Google Keep or Notes. If your phone is lost or stolen, you’ll still have all the info.
How to Reactivate an Old or Blocked Zong SIM
If you’ve not used your Zong SIM for months and it’s not working:
-
Insert the SIM into your phone
-
Try dialing any code (like
*222#) -
If there’s no response, go to a Zong service center
-
Bring your original CNIC
Zong may require biometric verification again. If you’re the original owner, you can usually get the number reactivated.
Using Your Zong Number for Apps and Registrations
Most apps in Pakistan like WhatsApp, Instagram, Easypaisa, JazzCash, and even Facebook use your phone number for login, security codes, and account recovery.
That’s why it’s risky to register these apps with a number you might forget or lose. You could get locked out permanently if you can’t access that SIM.
Always use your primary Zong number for app registrations. If you’re using a secondary SIM, write the number down somewhere safe or save it in your Google or Apple account.
Also, never use someone else’s Zong number for your apps. If that SIM is blocked or taken back, your accounts may be gone for good and recovery won’t be possible.
How to Block a Zong SIM
If your phone is stolen or lost, block your Zong SIM immediately to prevent misuse.
Here’s what to do:
-
Call 310 from any other Zong number
-
Give your CNIC number and answer some identity questions
-
Ask the agent to block the SIM right away
This process is usually quick and free of charge.
Zong Customer Service: What You Should Know
Zong’s helpline 310 works well most of the time, but if you call during rush hours, you may have to wait.
To save time:
-
Try calling early in the morning or after 9 PM
-
If the issue is serious (like SIM not working or CNIC mismatch), visit a Zong franchise instead
In bigger cities like Lahore, Karachi, and Islamabad, Zong is rolling out self-service machines. These kiosks let you:
-
Check your Zong number
-
Print bills
-
Recharge your balance
-
Update your thumbprint or CNIC info
They’re handy if you don’t want to wait in line.
Why Keeping Your Zong SIM Active Matters
PTA keeps a close eye on SIM usage in Pakistan. If your SIM is inactive for too long, it might be blocked automatically.
Inactive SIMs also stop receiving OTPs, which means you can’t log into banking apps, recover accounts, or get important messages.
To keep your Zong SIM active:
-
Send an SMS or make a short call every 3–4 weeks
-
Recharge a small amount — even Rs. 10 is enough
-
Use mobile data once in a while if it’s a data SIM
This small habit helps you avoid big issues later.
What to Do If Your Zong SIM Shows “No Service” or Isn’t Working
Trying to figure out how to check Zong SIM number but your phone says “No Service” or doesn’t detect the SIM at all? It’s a common issue, especially if the SIM hasn’t been used for a while.
Before you panic, try these quick steps:
-
Restart your phone
A simple restart often fixes signal problems and lets your phone recognize the SIM. -
Clean and reinsert the SIM
Dust or poor placement can cause the SIM to fail. Gently wipe it and place it back properly. -
Use another phone to check zong sim number
Insert the SIM into a different mobile to see if it works there. This helps rule out issues with your phone. -
Check network settings
Make sure your mobile network mode is set to “automatic” and that airplane mode is off. -
Try a USSD code anyway
Sometimes dialing*8#or*100#still works, even if signal bars are low. It’s worth a try if you want to know how to check my Zong number quickly.
If nothing works and you still can’t get a signal, the SIM may be expired or blocked due to inactivity. To solve this:
-
Visit the nearest Zong franchise
-
Bring your original CNIC
-
Ask them to check your SIM status and help you recover or replace it
Once your SIM is active again, you can easily use USSD codes or the My Zong app to check your number and other details.
How to Transfer a Zong SIM to Your Own Name (SIM Ownership Transfer)

Here’s how to do it:
-
Go to any Zong service center or franchise
Try to take the original SIM owner with you for a smooth process. -

Use the SIM with Easypaisa, WhatsApp, or JazzCash

Recover the number if your phone is lost or stolen
-
Dial
*8#to check the number anytime -
