Jazz Internet Settings Code in Pakistan: Prepaid, Postpaid and SMS 7342, Plus APN and 4G Checks

To get Jazz internet settings, dial *444*6*5# on a prepaid Jazz SIM or *446*4# on postpay, or send a blank SMS to 7342; Jazz then sends the settings to your phone by SMS. Save them when the phone asks, restart, and mobile data should start working.

That fixes most "internet not working on a new phone" problems. If it does not, the cause is usually a 3G SIM, a phone without 4G, or a bundle that has run out. Below are all the codes, the checks, and the hidden charge many people miss. We read Jazz's Process Help Center and 4G pages on 28 October 2026.

Jazz sends internet settings by SMS from three codes

Jazz gives one code for prepaid, one for postpay and one SMS number that works for both. Each one sends the settings to your phone as a message. On most Android phones you tap the message and choose Install or Save.

1. Put the Jazz SIM in the phone and switch mobile data on.
2. Dial the code for your connection, or send a blank SMS to 7342.
3. Open the settings message when it arrives.
4. Tap Install or Save. If the phone asks for a PIN that you do not know, call 111 rather than guessing.
5. Restart the phone.
6. Open a website to test.

The Jazz APN is "Jazz", but let the SMS fill it in

Jazz's help page lists the access point simply as "APN Jazz". It does not print the full address or the other fields. So the safest route is the settings SMS, which fills everything in for you, rather than typing values from a forum.

Some phones, especially iPhones and newer Android phones, set the APN automatically and never need the SMS. If your phone shows a Jazz profile under Access Point Names already, select it and leave it alone.

• Android: Settings, Mobile Network (or Connections), your Jazz SIM, Access Point Names. Pick the Jazz profile.
• iPhone: Settings, Mobile Service, Mobile Data Network. Most iPhones fill this from the SIM; leave it as it is unless Jazz asks you to change it.
• Dual SIM: make sure the Jazz SIM is the one chosen for mobile data.

Check that your SIM and phone are 4G

Settings alone cannot make a 3G SIM or a 3G phone run 4G. Jazz's 4G FAQ gives free checks: dial *443*7# to see whether your SIM is 4G, and *583# to activate the Super 4G service free. Jazz says activating 4G also keeps 2G and 3G on.

Jazz's pages give two different codes for checking whether the handset is 4G. One FAQ says *443*8#; the "Enable 4G" page says *4437#. Try the first, and if it fails, try the second.

If the SIM is old, swap it for a 4G SIM at a franchise. The 4G SIM and VoLTE check covers the swap. If you have a 5G phone, the same 4G SIM works on Jazz 5G; see the Jazz 5G supported phones list.

Jazz can charge for data even when mobile data looks off

Jazz's own Enable 4G page warns that a 4G connection stays connected even with mobile data switched off, and uses "a very small amount of data". Its advice is to switch the network to 2G or 3G before you turn data off, if you want to avoid that charge.

This matters when you have no bundle. Jazz's pages show two base rates for data used outside a bundle: Rs 5 per MB with a 512 KB charging pulse on one page, and Rs 3.6 per MB on another. Either way, a few MB without a bundle costs more than most daily bundles.

So buy a bundle before you use data, even for a minute. The Jazz monthly internet packages and the remaining MB check help you avoid running out mid-month.

Still no internet after the settings arrive

If the settings are saved and data still does not load, work through these checks. Most cases are one of the first three.

• No bundle or no balance: check your remaining MBs. Expired bundles do not auto-renew on many Jazz offers.
• Wrong SIM for data: on a dual SIM phone, choose the Jazz SIM under mobile data.
• 3G SIM: dial *443*7#. If it is not 4G, replace it.
• Network mode: set the preferred network to 4G/3G/2G auto, not 2G only.
• PTA status: an unregistered phone gets no service on any SIM.
• Area fault: try another place, or restart in airplane mode for 30 seconds.

Common questions

What is the Jazz internet settings code?

Dial *444*6*5# on prepaid or *446*4# on postpay. You can also send a blank SMS to 7342 from either.

What is the Jazz APN?

Jazz's help page lists it as "Jazz". It does not give the full access point address, so use the settings SMS to fill it in.

Is the Jazz internet settings SMS free?

Jazz's help page does not state a charge for the settings codes or the 7342 SMS.

How do I know if my Jazz SIM is 4G?

Dial *443*7#. Jazz says the check is free.

Why is Jazz charging me with mobile data off?

Jazz says 4G stays connected even with data off and uses a small amount of data. Switch to 2G or 3G before turning data off to avoid it.

How do I turn on Jazz 4G?

Dial *583#. Jazz says Super 4G activation is free and also keeps 2G and 3G active.

How we verified this

What we checked, where we read it, and what we could not confirm.

We read Jazz's Process Help Center, its Enable 4G page and the FAQ on its Jazz 5G SIM page on jazz.com.pk on 28 October 2026. We did not dial the codes ourselves. Jazz gives two different handset check codes and two different base data rates on different pages; we have shown both. The full APN address and any charge for the settings SMS are not on Jazz's pages.
