How To Convert Jazz, Zong, Telenor or Ufone SIM to Onic?

30 October 2026 • 7 min

Fed up with weak signals, slow data or bundles that cost too much? Good news: you can switch to Onic and keep the number everyone already knows. No new number, no messaging all your contacts.

In this guide, you'll learn the exact steps to convert your number, how long it takes, and what happens to your balance, old SIM and Whatsapp.

We've also added solutions to the problems people run into most. It's much easier than it sounds.

What is Mobile Number Portability and How Does It Work in Pakistan?

Mobile Number Portability (MNP) lets you change your network and keep your current number. You ask your new network, in this case Onic, to bring your number over. Onic sends the request to your old network, which checks that the number is yours and that it can be converted.

Once it's approved, your number starts working on your Onic SIM and your old network stops serving it. The networks handle the hard part behind the scenes. You only start the request and complete a few checks.

What Do You Need Before Porting Your Number to Onic?

Tick off this checklist before you begin, so nothing slows you down halfway:

  • Your original CNIC, with the number registered in your own name
  • A SIM that has been in use for at least 60 days
  • No recent change of ownership on the number
  • A number that is not registered in AJK (these can't be ported right now)
  • Your current SIM, active and in your phone, because you'll send SMS from it
  • A smartphone with internet and access to the Play Store or App Store
  • A working email address to sign up on the Onic app
  • A way to pay online for your chosen plan
  • A phone that supports eSIM, only if you want an eSIM instead of a physical SIM

How to Convert Your Jazz, Zong, Telenor, Ufone or Any Other Pakistani Network to Onic?

Switching to Onic is super simple! Just follow these easy steps:

STEP 1: Check Your Eligibility by Sending "MNP" to 667

From the SIM you want to move, send an SMS with the word MNP to 667. This checks whether your number can be ported to Onic. You'll get a reply, so keep it safe because you'll need it in Step 4.

STEP 2: Place Your Order and Choose "Port In"

If you're eligible, open the Onic app or website and place your order. Pick the plan you want and choose "Port In" as your number type. This tells Onic you want to keep your current number. Add your details and complete the payment to confirm the order.

STEP 3: Collect Your Onic SIM and Activate It

Pick up your Onic SIM from a nearby Onic SIM Pickup Point and complete the biometric verification there. Then open the Onic app, go to "Activate Your SIM", and scan the ICCID printed on the SIM card. You can also type it in by hand.

STEP 4: Forward the Reply From 667 to 76333

From your old SIM, forward the reply you received from 667 to 76333. This completes the conversion. Keep your old SIM in your phone until the switch is done.

How Long Does It Take to Port Your Number to Onic?

It depends on your connection type. Prepaid numbers take up to 4 business days. Postpaid numbers take longer, around 13 to 18 business days. Business days don't include weekends or public holidays, so start early in the week if you're in a hurry.

Will You Keep the Same Number After Switching to Onic?

Yes. That's the whole point of porting. Your number stays exactly the same. Only the network behind it changes, so your friends, family and work contacts can still reach you as before.

What Happens to Your Current Plan and Balance When You Switch?

Your old network's plan doesn't move with you. You'll pick a fresh Onic plan when you place your order, and that's the one you'll use after the switch. The same goes for leftover balance and unused data or minutes.

They stay with your old network, so try to use them up before you port. If you have a large balance, ask your old network if it can be refunded or used another way.

What Happens to Your Old Jazz, Zong, Telenor or Ufone SIM?

Once your number is ported, your old SIM stops working for that number. It won't get calls, SMS or data on it anymore. Don't throw it away until you've activated your Onic SIM and checked that everything works.

After that, you can safely discard it. If you use other numbers on the same old network, those are not affected.

What Happens to Your WhatsApp, Contacts and Accounts After Switching to Onic?

Since your number doesn't change, your WhatsApp account stays the same. Your contacts are saved on your phone or your Google or iCloud account, so they stay too. Banking apps, social media and other accounts linked to your number will keep working as well.

You may be asked to verify with a code, and that code will now arrive on your Onic SIM. Also, expect a short gap in service while the switch happens, so don't plan any important OTP logins for that moment.

Common Problems When Switching Your Number to ONIC and How to Fix Them?

Most people switch without any trouble. If you do hit a snag, these are the most common ones and how to sort them out.

1. My Port Request Was Rejected

Check the basics first. Numbers from AJK, SIMs used for less than 60 days and numbers with a recent ownership change can't be ported. If none of these apply, contact Onic support and they'll look into it.

2. I Didn't Get a Reply After Sending "MNP" to 667

Make sure you send the SMS from the number you want to move, that you typed MNP correctly, and that you have signal and enough balance to send an SMS. Try again after a few minutes. If it still doesn't work, reach out to Onic support.

3. My Number Is Registered Under Someone Else's CNIC

Porting only works when the number is registered in your name. Get the ownership transferred to your CNIC on your current network first. Because a recent ownership change can block porting, you may need to wait before you apply.

4. It's Taking Longer Than Expected

Prepaid numbers can take up to 4 business days. If that time has passed, call the Onic helpline on 051-111-339-111 or email happiness@onic.pk with your order details.

5. I Have No Signal After Activating My Onic SIM

Try these quick fixes:

  • Move the SIM to a different slot
  • Restart your phone
  • Turn Airplane Mode on and off
  • Try the SIM in another phone
  • Move to a different location

If the problem continues, contact OnicAI Assist.
