1. redONE USSD Codes (Updated 2026)

Primary USSD Code

Note for redONE Users: Since redONE is primarily a postpaid provider, many users don't need to check balance frequently. However, for prepaid (RED One Prepaid) users, the *123# menu is essential.
2. Yoodo USSD Codes (Updated 2026)
Yoodo is Malaysia's first fully digital, customizable telco, owned by CelcomDigi. Yoodo is unique because you build your own plan by choosing exactly how much data, voice, and SMS you want. However, because Yoodo is app-based by design, their USSD support is minimal but still exists for basic functions.
Primary USSD Code
- *118# – The main Yoodo USSD menu. This is the only code you really need to remember.
What You Can Do With *118#
- Check your remaining credit balance
- Check your remaining data quota (after you customized your plan)
- Check account validity and expiry date
- Purchase add-ons if you run out of data
Important Note About Yoodo (2026 Update)
Yoodo strongly encourages using the Yoodo app for full functionality. The USSD menu (*118#) only provides basic balance and data information. To change your custom plan, buy new add-ons, or manage your account, you must use the app or the Yoodo website.
Pro Tip: Yoodo does not have traditional top-up PINs. All reloads are done via the app using FPX, credit card, or e-wallets (Touch 'n Go, GrabPay). If you have zero data and cannot access the app, use *118# to buy a small data add-on over USSD.
3. unifi Mobile USSD Codes (Updated 2026)

Why Keep This USSD Guide Handy?
Even in 2026, USSD codes remain essential because:
- No internet needed – Works when your data runs out at midnight
- Works on any phone – Even old Nokia or emergency backup phones
- Faster than apps – 3 seconds vs 30 seconds
- No battery drain – Uses GSM network, not your phone's processor
Safety Reminder
Never dial a USSD code sent to you via SMS or WhatsApp claiming you won a prize. Scammers use fake codes like *123*XXXXXXXXX# to trick you into transferring credit. Only use codes from your telco's official website or this guide.
