Du Balance Check: The Fastest Way to Check Your du Balance in UAE

You know that moment, right? You’re about to make a long call, or you’re on the metro and the internet just stops. And the first thing that comes to mind is, did my balance finish, or did my data pack end?

Honestly, that’s why most people in the UAE check their du balance. Not every day. Just when it actually matters.

So here’s the thing, plain and simple. I’ll show you the ways du itself gives you, what changes if you’re on prepaid or postpaid, and how to check your data without guessing. Nothing extra.

Quick Answer: du Balance Check

Want the fastest way? Dial *135# from your du number and press call. That’s it. Your remaining credit shows up on your screen, and from the menu there you can check your data too.

Want a bit more detail? Open the du App. Credit, data, usage, it’s all right there on the home page. Or, if you’d rather hear it, call 135 and just follow what the voice says.

*135# and the 135 call don’t need internet. The du App and My Account do, so you’ll need data or Wi-Fi for those.

Du Balance Check Codes at a Glance

du’s own support pages list the du App, *135# and calling 135 for balance checks. du does not publish an SMS number for balance checks, so do not rely on an SMS code from other guides.

What You Will See When You Check

Here’s where people get confused, and it’s not really their fault. Prepaid and postpaid just don’t show you the same thing.

Prepaid? You’re checking what’s left. Simple. The money you still have for calls, SMS and data, before you need to recharge again. Plus how much data is left in your bundle, and when that bundle is going to end.

Postpaid is different. There’s no “money left” in that same way. You’re checking what you’ve already used this month, and how much has added up so far. Check it in the middle of the month and you won’t get a shock when the bill comes.

Prepaid: Remaining credit and data. Main method: *135# or du App.

Postpaid: Usage and unbilled amount. Main method: du App or My Account.

Data / Flexi bundle: Bundle balance left. Main method: *135# or du App.

How to Check du Balance by USSD Code

This is the one du puts first, and honestly, for most people it’s still the quickest.

Steps to Check du Balance With *135#

1. Open the dialler on the phone that has your du SIM in it.

2. Dial *135#.

3. Press call.

4. Wait a second. A message pops up on your screen with your remaining credit.

5. If a menu comes up, just follow the options on your screen to check data or your bundle.

No app to install, no login, nothing. Works on an old basic phone too, not just a smartphone.

One small thing, and it matters more than you’d think: dial it exactly like *135#, with the star at the start. I’ve seen guides write it as 135# without the star. That won’t work. Your phone won’t read it as a USSD code at all.

And if you’ve got two SIMs in your phone, double-check you’re dialling from the du one. The code checks the SIM you dial from. The other one won’t tell you anything.

How to Check du Balance on the du App

The USSD code gives you a number. The app gives you the full picture. Big difference, if you actually want to know what’s going on.

Steps in the du App

1. Download the du App from the App Store, Google Play, or Huawei AppGallery.

2. Log in with your du mobile number. First time? Just follow the registration steps inside the app, it doesn’t take long.

3. Your remaining credit and data should be right there on the home page, no digging around.

4. Tap on usage or your plan if you want the breakdown, data, calls, bundle validity, all of it.

Where the app really helps is the bundle end date. You can have credit left and still run out of data, because the bundle ended. The app shows you that clearly, so you’re not left wondering why the internet stopped.

Just remember, you need data or Wi-Fi to get into the app. No credit, no data, no Wi-Fi nearby? Use *135# instead. That one doesn’t need the internet at all.

How to Check du Balance by Calling 135

du lists this one itself in its prepaid balance help. Call 135, listen, follow the instructions.

Steps When You Call 135

1. Call 135 from your du number.

2. Listen to the voice menu, don’t rush it.

3. Pick the balance or usage option it offers you.

4. Write the balance down if you need it, especially if you’re checking before a recharge or a payment.

Yeah, it takes a bit longer than *135#, a minute or two. But some people just prefer hearing it, or they can’t read that little pop-up message clearly. Fair enough.

How to Check du Balance Online With My Account

On a laptop already? Or you want bills and history, not just today’s balance? Then My Account makes more sense.

Steps on My Account

1. Go to My Account on du.ae.

2. Log in with your du number, email, or username and password.

3. Open your account dashboard.

4. There it is, your balance, your usage, and if you’re postpaid, your bill details too.

It’s good for more than a quick check, past bills, downloads, managing your plan, all that. But for a fast balance check while you’re out? *135# or the app will beat it every time.

And please, don’t log in from some link that came in a random SMS. Go to du.ae yourself. And never, ever share your password or a one-time code with someone who calls or messages saying they’re from du.

How to Check du Data Balance

Credit and data aren’t the same thing. People mix them up all the time, and then they wonder why things stopped working.

You can have credit left and no data. Or data left and no credit. Checking one doesn’t tell you the other. That’s why a guide that only gives you a credit number and calls it complete, well, it isn’t.

Data Balance by USSD

Dial *135#, then use the menu that pops up to check data or bundle balance. The menu words can change from time to time, so read what’s actually on your screen instead of guessing which number to press.

Data Balance in the du App

Open the du App, home page, that’s where it is. Data used, data left, bundle end date. If you’ve got more than one bundle or add-on, check them one by one. The total left isn’t always the same as the main bundle left, and that catches people out.

du usually sends you alerts as you use up your data, but don’t just rely on those. Check in the app before a long video call or a big download. Going over can cost you, and it’s an easy thing to avoid.

du Balance Check for Prepaid Users

Prepaid is the straightforward one. You pay first, you use it, you check what’s left. That’s the whole idea.

*135# for a fast check. The du App for the full breakdown. Call 135 if you want the voice menu. All three, du lists them itself for prepaid credit and data.

One habit that’ll save you trouble: check before you recharge. If you don’t, you won’t know if the old credit was still sitting there, or if a bundle had already ended and your new recharge went somewhere you didn’t expect.

du Balance Check for Postpaid Users

Postpaid, you’ve got to think about it differently. You’re not checking money left. You’re checking how much you’ve used, and what’s built up so far.

The du App or My Account is where you do that. Usage this cycle, unbilled amount, bill details, it’s all there. *135# works too, through its menu, for usage information. But the app gives you the fuller picture, no contest.

And don’t panic if a postpaid check doesn’t look like a prepaid one. Usage and an amount owed, that’s normal. It doesn’t mean your service has stopped.

If the bill looks way higher than usual, don’t just pay it and hope. Check the usage breakdown first. Extra data? Calls outside your plan? An add-on you didn’t mean to keep? Look there first. Still doesn’t make sense after that? Contact du through the app or My Account.

What About Checking du Balance by SMS?

You’ve probably seen guides telling you to send BAL, or Balance, by SMS to some short number. I’d be careful with that one.

Here’s why. When du.ae was checked on 27 October 2026, du’s own prepaid balance help article listed three ways only: the du App, dialling *135#, and calling 135. No SMS number. No SMS keyword. Nothing.

And other guides? They don’t even agree with each other on the number. That’s the problem right there. Wrong number, no reply, or a message going to the wrong place. Stick with *135#, 135, or the du App, the ones du actually publishes. If du adds an SMS way later, it’ll be in their own help pages first.

Troubleshooting: When Your du Balance Check Does Not Work

Most of the time, when a balance check doesn’t work, it’s something simple. Go through these in order, don’t skip to the last one.

No Response After Dialling *135#

First things first. Did you dial *135#, with the star, from the du SIM? And do you actually have signal? If you’re in a basement or a lift, step near a window or outside and try again. No service at all, no USSD. It can’t reach du.

The Balance Looks Wrong

Give it a few minutes and check again. A recharge, a bundle renewal, a payment, they can take a little while to show up. Still looks wrong after that? Check in the du App too. If the app and the USSD result don’t match, note both numbers and the time, then contact du through the app.

You Cannot Log In to the du App or My Account

Check you’re using the right number and password, and that the app’s updated. Forgot the password? Use the reset option in the app or on the site. Don’t share that reset code with anyone, anyone at all. App still failing? Use *135# to get the balance itself, sort the login out later when you’re on Wi-Fi.

The Menu Options Look Different

du changes menu wording sometimes. It happens. Read the options on your screen instead of following some old screenshot step by step. If the option you wanted isn’t there, open the du App. Usage is right there, no menu to fight with.

Tips to Manage Your du Balance Better

Checking is only half of it. Not running out at the worst possible moment, that’s the other half.

Check before international calls, long video calls, big downloads. That’s when credit and data disappear fastest, you know that already.

Recharge the account. Not just the phone. Charging the battery doesn’t add credit, sounds obvious, but you’d be surprised. Recharge through the du App, My Account, or a trusted recharge point, then check the new balance after. Just to be sure.

Don’t set some reminder you’ll ignore. Just make it a habit. A quick *135# in the morning, on days you’re travelling or working away from Wi-Fi, that’s enough for most people. You don’t need to check every single day if your usage is light and your bundle is big.

And watch the bundle end dates, not just how much is left. A bundle can end with data still in it, and after that your data starts coming out of your credit instead. That’s a nasty surprise if you’re not watching for it.

Final Thoughts

Look, checking your du balance should take less than a minute. *135# for a fast answer. The du App when you want credit, data and usage all together. Call 135 if you’d rather hear it spoken.

Just remember the difference, credit and data aren’t the same, and prepaid and postpaid aren’t the same either. Once you’ve got that clear in your head, picking the right method is obvious. And you’re a lot less likely to run out right in the middle of something important.
