How to Recharge Du Online Without Logging In

- Step 2: Enter your UAE mobile number (starting with 055 or 052).
- Step 3: Choose your recharge amount or select a specific Data or Voice pack.
- Step 4: Securely pay using Visa, Mastercard, or Apple Pay.
- Benefit: This is the most efficient method for travelers who need an instant top-up using an international credit card while on the move.
Du Recharge Troubleshooting: Common Issues & Fixes
If your recharge is failing or you encounter an error, check these common solutions:
- Invalid Voucher Code: Double-check the 13-digit code on your scratch card. Ensure you are dialing the correct sequence:
*131* [13-digits] #. - SIM Status “Suspended”: In the UAE, if you do not recharge your SIM for more than 90 days, it may be suspended. You might need to visit a Du store with your Emirates ID or Passport to reactivate it.
- Payment Declined: If you are using a foreign bank card, ensure that “International Transactions” are enabled in your bank’s mobile app.
How to Transfer Balance from Du to Du
A great feature for families and friends is the “Credit Transfer” service. If someone is out of balance, you can send them some of yours instantly.
- The Code: Dial
*121* [Recipient's Number] * [Amount] # - Example: To send 20 AED to 0551234567, dial
*121*0551234567*20#. - Eligibility: You must have enough “More Time” credit in your account to perform this transfer. A small transaction fee may apply.
Recharging from Abroad: Keep Your UAE SIM Active
If you are outside the UAE and want to prevent your SIM from expiring, you can still top up.
- The My Du App works globally as long as you have internet access.
- Using the official website is recommended to avoid the high service fees charged by third-party international top-up websites.
- Expert Tip: Recharging at least AED 25 every 3 months is the safest way to keep your UAE number active while you are away.
After recharging, make sure to check your Du balance to confirm the transaction.

Frequently Asked Questions (FAQs) About Du Recharge
How can I get a bonus on my Du recharge?
The best way to get a bonus is by recharging through the My Du App. Du frequently offers “Deal of the Day” rewards or 10-20% extra credit for digital top-ups. You can also dial *055# to check for personalized recharge offers.
Can I use a 5-dirham recharge for data?
Yes, but a 5 AED recharge is usually added to your “More Time” balance. To convert it to data, you would need to dial *135# after recharging and subscribe to a small daily data pack.
What is the Du recharge code for data only?
There isn’t a single “recharge code” for data. Instead, you recharge your main balance using *131*Code# and then dial *135# to select a data plan. Alternatively, you can buy a dedicated “Data SIM” recharge card at most supermarkets.
Can I recharge my Du SIM using a Nol Card?
Currently, you cannot directly use Nol Card balance to recharge your SIM. However, at many RTA Self-Service Machines in Metro stations, you can pay for your Du recharge using cash or a bank card at the same kiosk where you top up your Nol card.
How do I fix the “Invalid MMI Code” error when recharging?
This usually happens due to a weak network signal or an incorrect code format. Ensure you have full bars, and try using the My Du App or the official website if the USSD code (*131*) continues to fail.
