The Ultimate Guide to USSD Codes for Maxis, Digi, Yes 4G, Celcom, U Mobile, XOX & Tune Talk (Updated 2026)
In an era where we rely on 5G and WiFi 6, it is easy to forget the humble workhorse of mobile connectivity: the USSD code. Those short strings of numbers starting with asterisks (*) and ending with hashes (#) remain the fastest way to check your balance, buy internet data, or get customer support, especially when your internet connection is down.
As of 2026, Malaysia's major telcos have refined their systems. Here is your complete updated cheat sheet covering 8 telcos including Maxis, Digi, Yes 4G, Celcom, U Mobile, XOX, and Tune Talk.
What Are USSD Codes?
USSD codes are text-based menus that connect you directly to your telco's server. Unlike SMS, they are real-time. You dial a code, and the response pops up instantly on your screen.
1. Maxis & Hotlink USSD Codes (2026)
Maxis has maintained its classic codes for 2026, focusing on simplicity for both Postpaid and Hotlink Prepaid users.
Balance & Account Inquiry
- *122# – The most important code. Checks your main credit balance and account status.
- *100# – Access the main Hotlink and Maxis service menu.
- #100# – Check your mobile number if you forget which line you are using.
Internet & Data
- *136# – Check your remaining internet data quota and validity period.
- *118# – Purchase internet add-ons or new data passes (very popular for emergency top-ups).
- *100*1*1# – Check your 5G access status.
Customer Support
- *123# – General help and support information.
- *555# – Direct link to Maxis Customer Service menu (request a call back).
2. Digi USSD Codes (2026)
Following its continued integration with Celcom (now merged under "CelcomDigi"), the blue network has kept its legacy codes active.
Balance & Credit
- *126# – Check your prepaid credit balance.
- *128# – Access the Digi Smart Menu (the central hub for everything).
- *200# – Check your remaining high-speed data and basic internet quota.
Purchasing & Plans

Customer Service
- *128# then select "Customer Service" – The easiest way to get help without searching for a phone number.

Celcom remains one of Malaysia's most reliable networks, and their USSD system is straightforward and easy to use.

Internet & Data
- *118# – Access the main Celcom prepaid menu for checking data balance and purchasing plans.
4. Yes 4G (YTL Communications) USSD Codes
Yes 4G operates a bit differently because it was one of the first fully 4G (now 5G) networks. However, they still maintain a core set of USSD commands for prepaid users.
- *123# – Universal portal. From here you can check credit, buy plans, and check your reward points.
- *124# – Check your remaining data quota specifically.
- *150# – To reload (top-up) your account instantly using a reload pin.
- *130# – Check your Rewards points (Yes Rewards loyalty program).
Note on Yes: Unlike other telcos, Yes encourages users to use the "Yes Connect" app for most heavy lifting. If a USSD command fails, it is likely due to the app being the primary interface, but *123# remains the universal backup.
5. U Mobile USSD Codes (2026)
U Mobile is known for its affordable prepaid plans like GX48 and U Postpaid. Their USSD system focuses on simplicity.
Main Codes
- *118# – The primary U Mobile USSD menu. From here you can check balance, buy data plans, and manage your account.
Source: U Mobile support documentation [citation:2] - *118*3*3# – Quick check for remaining high-speed data quota.
- *118*6# – Check your account validity and active plans.
Top-Up & Purchases
- *118*5# – Purchase internet add-ons.
- Top-up via PIN: Dial *118*<PIN number># to reload using a prepaid top-up card.
6. XOX Mobile USSD Codes (2026)
XOX is famous for its flexible "Season Pass" system and long validity periods. While they push users toward the BLACK app, the USSD shortcut is still alive and well.
Primary Code
- *150# – The main XOX USSD portal. Dial this to check your balance, view Season Pass status, and manage your account.

What You Can Do With *150#
- Check remaining credit balance
- View Season Pass data quota
- Check account expiry date
- Buy data add-ons
Pro Tip for XOX Users: XOX is unique because your main credit and Season Pass data are separate. Use *150# to monitor both, but note that the official BLACK app gives you more detailed breakdowns of your transferable data.
7. Tune Talk USSD Codes (2026)
Tune Talk, backed by AirAsia, remains popular for its EPIK prepaid plans. Their USSD and SMS system is one of the most organized in Malaysia.

Why Bother with USSD in 2026?
You might be asking, "Why not just use the app?"
Three reasons to keep this guide bookmarked:
- No Internet Required: When your data quota finishes at 11:00 PM and you need to buy a plan, your WhatsApp won't load, but USSD codes will work instantly.
- Speed: Navigating an app takes 30 seconds. Loading a USSD menu takes 3 seconds.
- Battery Saver: On an old phone or low battery mode, running a heavy telco app drains resources. USSD codes run on the GSM network, not your phone's processor.
Safety Reminder
Be cautious of scam SMS messages asking you to dial strange codes like *123*[some number]#. Never dial a code that someone sends you via text message to "claim a prize." Legitimate USSD codes for your account are listed on the official websites or this guide above.
Disclaimer: While these codes are accurate as of May 2026, telcos occasionally update their systems. If a code fails, try the main portal command for that telco to navigate manually.
