This troubleshooting guide solves every common error you’ll encounter with 667 and 668. Real problems, instant solutions, no technical jargon.

ERROR #1: No Reply from 667 After Sending MNP

Symptoms:

Sent “MNP” to 667
Waited 5+ minutes
No reply received
No error message

Common Causes & Solutions:

Cause 1: Typed Lowercase “mnp”

Problem: Some networks require capital letters

Solution:

✅ Type: MNP (all capitals)
❌ Not: mnp
❌ Not: Mnp
❌ Not: mNp

Test: Delete message, type fresh “MNP” in capitals, send again

Cause 2: Added Extra Text

Problem: System only recognizes exact “MNP”

Examples of WRONG formats:

❌ "MNP check"
❌ "MNP 03001234567"
❌ "Please check MNP"
❌ "MNP " (extra space after)

Correct format:

✅ MNP (exactly three letters, nothing else)

Solution: Type ONLY “MNP”, nothing before, nothing after

Cause 3: Sent to Wrong Number

Problem: Sent to 668 instead of 667, or other number

Check your sent message:

Recipient should be exactly: 667
Not 668
Not 0667
Not 666 or 677

Solution: Send to exact shortcode 667

Cause 4: SIM Card Not Properly Inserted

Problem: Loose SIM or phone not detecting SIM properly

Symptoms:

Phone shows “No SIM” or “Emergency calls only”
Signal bars empty or flickering

Solution:

Turn off phone completely
Remove SIM card
Clean SIM card gently with soft cloth
Reinsert firmly
Turn on phone
Wait for full signal (3-4 bars)
Try MNP to 667 again

Cause 5: Network Congestion

Problem: Peak hours overload (9-11 AM, 7-9 PM)

Solution:

Wait 10 minutes
Try again
Or try during off-peak hours (2-4 PM, late night)

Cause 6: SIM is Blocked/Suspended

Problem: SIM has been blocked by operator or PTA

Check:

Can you make regular calls?
Can you send regular SMS?
If NO to both = SIM is blocked

Solution:

Visit operator franchise
Check block reason
Resolve issue (usually biometric verification needed)
Then 667 will work

Cause 7: Using Expired/Old SIM

Problem: SIM hasn’t been used for 90+ days

Signs:

“SIM not registered” message on phone
Can’t make calls or SMS

Solution:

This SIM is deactivated
Visit operator franchise
Reactivate SIM (may need new registration)
Then check via 667

ERROR #2: 667 Says “Invalid Format”

Symptoms:

Reply received but says:

“Invalid format”
“Invalid request”
“Message not recognized”

Solutions:

Solution 1: Check Exact Spelling

Must be: M-N-P (in that order)

Common mistakes:

❌ NPM
❌ MPN
❌ NMP
❌ MNP. (with period)
❌ MNP? (with question mark)

Solution 2: Check for Hidden Characters

Problem: Copied from somewhere, has invisible characters

Solution:

Don’t copy-paste “MNP”
Manually type M, then N, then P
Send

Solution 3: Network-Specific Format

Some operators require:

Jazz: Usually accepts MNP
Zong: Try “MNP ” or “mnp” if MNP fails
Telenor: Strictly “MNP” capitals
Ufone: “MNP” capitals

Solution: Try variations if one doesn’t work

ERROR #3: 667 Shows Different Name Than Expected

Symptoms:

Sent MNP to 667
Reply received successfully
But name shown is NOT yours
Or different family member’s name

This Is NOT An Error – It’s Important Information!

Scenario 1: SIM Registered to Different Person

What it means:

This SIM is legitimately registered to the name shown
Could be:
- Family member’s SIM
- Previous owner (if you bought used)
- Corporate SIM
- Unauthorized registration

What to do:

If it’s family member you recognize:
✅ Normal – your parent/spouse registered it under their name
✅ No action needed unless you want to transfer ownership

If it’s unknown person: 🚨 ALERT – Possible fraud

Don’t use this SIM for sensitive activities
Visit operator franchise immediately
Show them 667 result
Verify registration details
If unauthorized, file complaint

If you bought this phone/SIM second-hand: ⚠️ Ownership not transferred

Contact seller
Request proper ownership transfer
Visit franchise together
Complete transfer process
Re-check with 667 (should show YOUR name now)

Scenario 2: Franchise Error During Registration

What happened:

You registered SIM at franchise
Staff made error
Registered under wrong CNIC (similar number)
Or registered under staff’s own CNIC

What to do:

Return to same franchise immediately
Bring original registration receipt
Show 667 result proving wrong registration
Demand re-registration under correct CNIC
Complete process same day
Verify with 667 after 24 hours

Real case: Karachi resident’s new Jazz SIM showed franchise employee’s name via 667. Staff had mistakenly used their own CNIC instead of customer’s. Corrected within 2 hours.

ERROR #4: 667 Shows “BVS: Not Verified”

Symptoms:

Name: Your Name
CNIC: 35201-XXXXXX-1
Network: Jazz
Status: Active
BVS: Not Verified ⚠️

What This Means:

BVS = Biometric Verification System

“Not Verified” means:

Your fingerprints not registered with this SIM
Or biometric verification expired
Or never completed

Danger Timeline:

Days Since Registration	Status	Action
0-30 days	⚠️ Warning period	Visit franchise soon
31-60 days	🟠 Restriction starts	Outgoing calls limited
61-90 days	🔴 Heavy restriction	Only incoming calls
91-120 days	🔴 Final warning	SMS only
121+ days	⛔ BLOCKED	SIM permanently blocked

Solution – Visit Franchise TODAY:

What to bring:

Original CNIC card
The SIM showing “Not Verified”
Phone with the SIM inserted

At franchise:

Request: “Biometric verification for this SIM”
Staff will scan your fingerprints
System matches with NADRA
Process takes 5-10 minutes
Get confirmation receipt

After verification:

Wait 24-48 hours
Send MNP to 667 again
Should now show: “BVS: Verified” ✅

Don’t delay! After 120 days, SIM blocks permanently. No recovery possible.

ERROR #5: 667 Shows Wrong Network

Symptoms:

Your SIM is Jazz
But 667 shows “Network: Zong”
Or vice versa

Possible Causes:

Cause 1: MNP (Number Porting) History

What happened:

You ported number from Zong to Jazz
PTA database still shows old network
Database sync delay

Check:

What’s your current operator (check SIM packaging)?
667 shows old operator = normal MNP delay

Solution:

If ported within last 7 days: Wait, database updating
If ported 30+ days ago: Visit current operator
Request database sync
Should update within 48 hours

Cause 2: Wrong SIM Inserted

What happened:

You think you inserted Jazz SIM
Actually inserted Zong SIM
Phone doesn’t clearly show operator

Solution:

Remove SIM
Check SIM card color/branding
Check SIM packaging
Verify actual operator
667 is probably correct, you inserted wrong SIM

ERROR #6: No Reply from 668 After Sending CNIC

Symptoms:

Sent 13-digit CNIC to 668
Waited 5+ minutes
No response at all

Common Causes & Solutions:

Cause 1: CNIC Format Wrong

Most common mistake: Included dashes

❌ Wrong: 35201-1234567-1
✅ Correct: 3520112345671

Solution:

Look at your CNIC card
Type ONLY the numbers
Skip all dashes
Should be exactly 13 digits
Send to 668

Cause 2: Wrong Number of Digits

Problem: Typed 12 or 14 digits instead of 13

Count your digits:

3 5 2 0 1 1 2 3 4 5 6 7 1
1 2 3 4 5 6 7 8 9 10 11 12 13 ✅

Common mistakes

❌ 352011234567 (only 12 digits - missing last digit)
❌ 35201123456711 (14 digits - typed last digit twice)

Solution: Count carefully, must be EXACTLY 13 digits

Cause 3: Sent to 667 Instead of 668

Check your sent message:

If you sent to 667 = wrong (that’s for MNP)
Should send to 668 for CNIC check

Solution: Send your 13-digit CNIC to 668 (not 667)

Cause 4: Network Issues

Similar to 667 problems:

Weak signal
Network congestion
SIM issues

Solution:

Check signal strength (3+ bars needed)
Try from different location
Try during off-peak hours
Try from different network SIM if possible

ERROR #7: 668 Says “Invalid CNIC” or “CNIC Not Found”

Symptoms:

Reply received saying:

“Invalid CNIC number”
“CNIC not found in database”
“CNIC not registered”

Causes & Solutions:

Cause 1: Typed Wrong CNIC Number

Problem: Made typing mistake

Solution:

Get your physical CNIC card
Look at it while typing
Type slowly, verify each digit
Double-check before sending
Count: must be 13 digits total

Pro tip: Read it out loud while typing to avoid mistakes

Cause 2: Very New CNIC

Problem: CNIC issued within last 7-15 days

What happens:

NADRA issued your CNIC
PTA database not synced yet
Takes 7-15 days for sync

Solution:

Wait 2 weeks after CNIC issuance
Try 668 again
If still not working after 30 days, visit NADRA

Cause 3: CNIC Expired/Blocked

Problem: CNIC validity expired or blocked by NADRA

Check:

Look at CNIC card expiry date
Expired? Need to renew
Blocked? Visit NADRA to resolve

Solution:

Renew/unblock CNIC first
Wait 7 days after renewal
Try 668 again

Cause 4: Using Someone Else’s CNIC

Problem: Typed someone else’s CNIC to check their SIMs

What happens:

If their CNIC has privacy restrictions
Or if CNIC is not registered with NADRA
System returns “not found”

Solution:

Only check your own CNIC
Or immediate family with permission
If checking spouse/parent, ensure CNIC is valid

ERROR #8: 668 Shows 0 SIMs But I Have Active SIMs

Symptoms:

Total: 0
Jazz: 0
Zong: 0
Telenor: 0
Ufone: 0
SCO: 0

But you definitely have 2-3 active SIMs!

Possible Reasons:

Reason 1: SIMs Registered on Different CNIC

What happened:

You think SIMs are on YOUR CNIC
Actually registered on:
- Parent’s CNIC
- Spouse’s CNIC
- Sibling’s CNIC
- Company CNIC

How to verify:

Insert each SIM one by one
Send MNP to 667 from each
Check whose name appears
That person’s CNIC has the registrations

Solution:

Send THAT person’s CNIC to 668
Will show the SIM counts
If you want SIMs on your CNIC, request transfer at franchise

Reason 2: Checked Wrong CNIC

What happened:

You have 2 CNICs (old + new after name/correction)
Checked new CNIC via 668
But SIMs registered on old CNIC

Common scenarios:

CNIC renewed with number change
Name correction led to new CNIC number
Marriage led to CNIC update

Solution:

Find old CNIC number
Send old CNIC to 668
Will show SIM registrations
Visit franchises to transfer to new CNIC

Reason 3: Very Recent SIM Registrations

What happened:

Registered SIMs yesterday or today
PTA database not updated yet
Takes 24-48 hours to reflect

Solution:

Wait 48 hours
Try 668 again
Should appear then

Reason 4: All SIMs Were Recently Blocked

What happened:

PTA blocked all your SIMs (biometric issue, etc.)
Blocked SIMs don’t show in 668 count

Check:

Try making calls from your SIMs
If all blocked → shows 0 in 668

Solution:

Visit operator franchises
Resolve blocking reason
Reactivate SIMs
Will appear in 668 after reactivation

ERROR #9: 668 Count Doesn’t Match My Actual SIMs

Symptoms:

You have 3 SIMs
668 shows 5
Or you have 5 SIMs
668 shows 3

When 668 Shows MORE Than You Have:

Scenario A: Unauthorized SIMs

What it means: Someone registered SIMs on your CNIC without permission

Example:

You own: 2 Jazz, 1 Zong = 3 total
668 shows: Jazz: 4, Zong: 1 = 5 total
Problem: 2 unauthorized Jazz SIMs exist

Immediate action:

Note which operator has extra count
Visit that operator franchise TODAY
Request: “CNIC SIM Registration Printout”
Get list of all numbers
Identify unauthorized ones
File SIM Disowning Request
Block unauthorized SIMs

Read full guide: How to Block Unauthorized SIMs

Scenario B: Forgotten Old SIMs

What happened:

You registered SIMs 5+ years ago
Forgot about them
Never deactivated
Still count in 668

Examples:

Old workplace SIM
SIM from previous city
Backup SIM never used
Trial SIM from promotion

Solution:

Get printout from operator (method above)
Identify old numbers
Deactivate ones you don’t need
Keep only active ones

When 668 Shows LESS Than You Have:

Scenario C: SIMs on Multiple CNICs

What happened:

Some of “your” SIMs are on other family CNICs
You’re not sure which is which

Example:

You think you have: 5 SIMs
668 shows: 3 SIMs
Missing: 2 SIMs are on parent/spouse CNIC

Solution:

Use 667 method on each SIM
Check whose name appears
That tells you which CNIC has it

Scenario D: Recent Deactivations Not Synced

What happened:

Deactivated SIMs last week
668 database not updated yet
Shows old higher count

Solution:

Wait 7 days after deactivation
Try 668 again
Should show updated count

ERROR #10: Operator Breakdown Seems Wrong

Symptoms:

668 result: Jazz: 3, Zong: 2, Telenor: 0
But you know you have 1 Telenor SIM!

Solution Process:

Step 1: Verify with 667

Insert your Telenor SIM → Send MNP to 667

Possible results:

Result A: Shows different person’s name

Telenor SIM is NOT on your CNIC
It’s on someone else’s (parent/spouse)
That’s why 668 doesn’t show it

Result B: Shows YOUR name

Telenor SIM IS on your CNIC
But 668 shows 0
This is database error
Proceed to Step 2

Step 2: Visit Telenor Franchise

Say: “668 doesn’t show my Telenor SIM but 667 confirms it’s mine”

Staff will:

Check your CNIC in system
Verify registration
Update database if needed
Sync with PTA

Wait 48 hours, check 668 again

ERROR #11: Extremely Slow Response (30+ Minutes)

Symptoms:

Sent MNP to 667 or CNIC to 668
Reply came but after 30-60 minutes
Or still waiting after hours

Causes:

Cause 1: System Maintenance

When: Usually late night (1-4 AM)

Solution:

Check PTA official Twitter for maintenance announcements
Try during daytime hours

Cause 2: National Emergency/Event

When:

Elections day
National emergency
Major security situation

What happens:

All SMS services slowed for security
Verification systems deprioritized

Solution: Wait for situation to normalize

Cause 3: Your Operator’s Issue

Problem: Your network is slow, not 667/668 service

Solution:

Try from friend’s SIM (different operator)
If works fast = your operator issue
Complain to your operator

ERROR #12: Service Completely Down

Symptoms:

Multiple people trying
No one getting replies
Different operators, different phones, all failing

How to Confirm Service is Down:

Check 1: PTA Official Channels

Twitter: @PTAofficialpk
Website: pta.gov.pk
Look for service outage announcements

Check 2: Ask Others

Family/friends try from their phones
If all failing = service down
If some working = your phone/SIM issue

What to Do:

If officially down:

Wait for PTA to restore
Usually restored within 2-6 hours
Check PTA announcements for updates

If not officially announced but still not working:

Wait 2 hours
Try again
If still failing after 12 hours, call PTA helpline: 080055055

ERROR #13: Works on One Network, Not Another

Symptoms:

667/668 works from Jazz SIM
But fails from Zong SIM
Same phone, same location

Cause: Operator-Specific Block

What happened:

Your Zong SIM specifically has SMS restrictions
Could be:
- Unpaid bills blocking outgoing SMS
- Temporary operator suspension
- SMS package expired

Solution:

Check 1: Can you send regular SMS?

Try sending SMS to friend
If regular SMS also fails = SMS blocked on your SIM
Pay bills or visit franchise

Check 2: Try from different SIM of same operator

Borrow friend’s Zong SIM
Try 667/668
If works = problem is YOUR specific SIM
If fails = operator-wide issue with 667/668

ERROR #14: 667 and 668 Results Contradict

Symptoms:

Example:

668 shows: Jazz: 3
You own: 2 Jazz SIMs
Both 667 checks show YOUR name on both

Where is the 3rd Jazz SIM?

This Is NOT Contradiction – It’s Discovery!

What it means:

668 found a Jazz SIM you don’t physically have
667 can only check SIMs you insert
3rd SIM exists somewhere

Solution:

Step 1: Get Jazz SIM List

Visit Jazz franchise
Request: “Complete list of all Jazz SIMs on my CNIC”
They’ll print all numbers

Step 2: Compare

Jazz printout shows 3 numbers:
- 0300-1234567 (recognize - your SIM #1) ✅
- 0300-7654321 (recognize - your SIM #2) ✅
- 0321-9999999 (DON'T recognize) 🚨

Step 3: Identify the Unknown

Try calling it (see if someone answers)
Ask family if they recognize it
Check old records/receipts

Step 4: If Unauthorized

File disowning request at franchise
Block it immediately

This is 668’s superpower – it finds SIMs you don’t know about!
