What Are The Main Methods for DU Balance Check?

1. USSD Code Dialing
2. Texting an SMS Code
3. Using the DU App
4. Visiting the DU Online Portal
5. Calling Customer Care

Each one is straightforward. Let’s explore each method step by step, with a few helpful tips along the way.

Method #1 – DU Balance Check via USSD Code

A USSD (Unstructured Supplementary Service Data) code is probably the quickest way to see your DU balance. It works right from your phone’s dialer, without needing data or a special app.

• Dial #135# and press the call button.
• Wait a few seconds, and your remaining balance should appear on your screen.

This is the main DU balance number for quick checks. If you have a prepaid line, you’ll see how many dirhams remain. If you have a postpaid line, you might see limited information, but it still gives some details, such as outstanding charges or usage.

USSD Code for Data Balance

• Dial #135*1# to see how much data is left.
• If you have trouble, try repeating the process or checking your network signal.

DO YOU KNOW BOX

• DU first appeared in 2006 as the second licensed telecom provider in the UAE.
• It serves millions of users with mobile, broadband, and other digital services.

Method #2 – DU Balance Check Using SMS Code

If you prefer sending a text to see your DU balance, you can use the SMS method:

• Go to your messaging app.
• Write “Balance” in the message.
• Send it to 1355.

You’ll receive a reply with your current DU balance. This approach is handy if your phone’s USSD isn’t responding or you’re in a place with a low signal but can still send texts.

WARNING BOX

• Double-check the number 1355 before sending. Sending “Balance” to a different number might cost you or not work at all.
• If you’re travelling outside the UAE, SMS charges might differ, so keep that in mind.

Method #3 – Checking DU Balance via the DU App

For people who love digital convenience, the DU App is a great choice. It provides a quick look at your usage, offers, and account details. Here’s how to set it up:

1. Download and install the DU App from your phone’s app store (Android or iOS).
2. Open the app and sign in with your DU mobile number.
3. Look for the “Usage” or “Account” section to see your remaining minutes, SMS, or data.

You can also recharge directly from the app if you’re on prepaid, or settle your bill if you’re on postpaid.

TIP BOX

• The app often includes special offers or discounted rates for recharges.
• Keep your app updated to access the latest features and improvements.

Method #4 – DU Balance Check Online

If you spend a lot of time on a computer or prefer a bigger screen, you can use DU’s official website:

1. Go to www.du.ae.
2. Log in to your account or register if it’s your first time.
3. Navigate to the “My Account” or “Billing” section for balance and usage details.

This option is especially helpful for postpaid users who want to see a detailed breakdown of monthly bills and add-ons. Prepaid users can check their credit and validity. It’s also handy for business owners managing multiple lines.

Method #5 – DU Balance Check via Customer Care

When all else fails, or if you need a human touch:

• Dial 155 from your DU phone.
• Follow the instructions to get your balance.

Or, choose to speak with a customer service agent if the automated system isn’t giving you what you need. Keep your phone number and personal info ready for verification.

STATS BOX

• Over 7 million subscribers in the UAE rely on DU for mobile services.
• 55% of DU users still prefer USSD codes for quick balance checks.
• 40% of new DU customers download the DU App within their first week of joining.

DU Prepaid Balance Check: A Closer Look

Prepaid is popular among students, temporary residents, and light phone users. You load credit, and each time you call, text, or use data, the amount is deducted. Keeping track of your balance is essential to avoid disconnection.

DU Prepaid Balance Check

• #135#: Main USSD for call and SMS credit.
• #135*1#: Check remaining data.
• SMS “Balance” to 1355: Receive an instant text with your balance.
• DU App: Log in and see your overall usage.
• Website: Check your account details after signing in.

INFO BOX

• Prepaid lines need regular recharges to stay active.
• If your balance expires, you might lose unused minutes or data.

DU Postpaid Balance Check: A Better View of Monthly Usage

Postpaid plans offer monthly billing, making them popular for those who need higher amounts of data or call minutes. You get a set quota and pay at the end of each cycle. Monitoring your usage helps you avoid excess charges.

DU Postpaid Bill Check

• DU App: Look under “Bill” or “Usage” for your total charges.
• Online Portal: Sign in at www.du.ae and view your recent statements.
• Customer Care: Dial 155 and ask for your balance or outstanding amount.

Tracking your usage mid-cycle can show if you’re nearing your limit. This is a good strategy to prevent paying for extra data or minutes.

DU Data, SMS, and Call Balance Details

Knowing the difference between each balance type can help you plan:

• Data Balance: How many MB or GB you have left for internet use.
• SMS Balance: The number of texts you can still send.
• Call Minutes Balance: The remaining minutes for local or international calls.

All three can be seen using the USSD codes (#135# and #135*1#) or the DU app.

DO YOU KNOW BOX

• Many DU packs combine calls, data, and SMS in one bundle, making it more cost-effective than buying each separately.

DU Balance Validity and Why It Matters?

Balance validity tells you how long your credits, data, or call minutes will remain active. If you don’t use them within the set period, they can expire. To check validity:

• Dial #135# and look for any mention of expiry dates.
• Open the DU App and check the “Validity” or “Expiry” fields.

If you see your plan is about to expire, consider recharging or paying your bill. This way, you don’t lose what you’ve already paid for.

Handy DU Recharge Options

Once you know your DU balance is low, the next step is to recharge:

1. Physical Recharge Cards: Scratch the card and dial the code to add credit.
2. Digital Platforms: Use the DU app or www.du.ae to pay with a debit or credit card.
3. Bank ATMs or Payment Kiosks: Some ATMs and machines allow direct top-ups.

Keep your receipts or transaction IDs in case anything goes wrong. It’s rare, but it helps to be safe.

Issues with DU Balance Not Updating

Sometimes, after making calls or using data, the balance might not change right away. Possible reasons include:

• System Delays: DU’s servers might be busy.
• Network Glitch: Low signal strength could cause delays.

How to Transfer DU Balance?

Sharing your DU balance with someone is easy. First, make sure you have enough credit in your own account. Then, follow these steps:

• Open your phone’s dialler.
• Type 121055XXXXXXX*AMOUNT# (no spaces).
• Replace 055XXXXXXX with the payee’s actual mobile number.

This transfer option is helpful when friends or family need an urgent top-up but can’t buy credit right away. Always remember to check your balance before sending credit so you don’t run out by accident. If you see any errors, try again or call DU customer care for help.
