FAB OTP Not Received in UAE (2026): Reasons, Fixes & Instant Solutions
If your FAB OTP is not received in UAE, it can be frustrating especially when you need urgent access to your bank account for login,FAB balance check payments, or transfers.
This issue can completely block your access and create unnecessary stress, particularly when you don’t know what’s causing it.
The good news is that in most cases, this problem is temporary and fixable within minutes.
In this guide, you’ll learn the exact reasons why your FAB OTP is not coming, along with step by step solutions that actually work so you can quickly regain access to your account without confusion
What Is FAB OTP and How It Works
An OTP (One-Time Password) is a temporary security code sent to your registered mobile number when you:
- Log in to your account
- Transfer money
- Add a beneficiary
- Confirm sensitive actions
It ensures:
- Only you can access your account
- Transactions are verified securely
- Unauthorized access is blocked
Without OTP, you won’t be able to complete most banking actions in FAB.
Main Reasons Why FAB OTP Not Received
Your FAB OTP may not arrive due to several common technical and system related reasons. Understanding the exact cause is the fastest way to fix the issue.
1- Weak Mobile Network
If your signal is low, OTP messages may be delayed or not delivered at all. This is common in indoor or crowded areas.
2- SIM Card Issues
An inactive SIM, damaged card, or insufficient balance can block incoming SMS, including OTPs.
3- Incorrect Registered Mobile Number
If your number is outdated in the FAB system, the OTP will be sent to the wrong number.
4- Phone Settings Blocking Messages
Do Not Disturb mode or spam filters can silently block OTP messages.
5- Temporary Bank Server Delay
Sometimes FAB systems experience delays, especially during peak hours or high traffic.
6- Roaming Disabled (Outside UAE)
If you are traveling, OTP messages may not arrive unless international roaming is enabled.
7-Dual SIM Confusion
On dual SIM phones, OTP may be received on a different SIM slot than expected.
How to Fix the FAB OTP Not Received Issue
If your FAB OTP is not coming or working, you don’t need to try everything randomly. Follow this structured approach based on your situation:
1- Check Your Mobile Signal
If your network signal is weak, OTP messages may not arrive.
➡️ Move to an open area or a place with better coverage and try again.
2- Restart Your Phone
Sometimes the issue is just a temporary device glitch.
➡️ Restart your phone to refresh network connections and SMS services.
3- Verify Your SIM Status
An inactive or damaged SIM can block OTP messages.
➡️ Make sure your SIM is active, inserted properly, and has sufficient balance.
4- Wait and Request OTP Again
Delays can happen due to system load.
➡️ Wait for 2–5 minutes and then request a new OTP.
5- Check Your Registered Mobile Number
If your number is outdated, OTP will be sent to the wrong number.
➡️ Update your mobile number with First Abu Dhabi Bank if needed.
6- Enable Roaming (If You Are Abroad)
OTP messages may not be delivered outside UAE without roaming.
➡️ Turn on international roaming in your mobile settings.
7-Contact FAB Support
If none of the above solutions work, the issue may be from the bank’s side.
➡️ Contact FAB customer support for verification and assistance.

Most FAB OTP issues are resolved within minutes by following these steps in order. Start with the basics (network and device) before contacting support.

When FAB OTP Issues Are NOT Your Fault (Server & System Problems)
Sometimes, the issue is not on your side — it’s coming from the bank’s system.
1) Common Bank-Side Issues
Systems at First Abu Dhabi Bank may experience:
- Temporary server downtime
- Scheduled system maintenance

- Multiple requests may slow down delivery further
3) What You Should Do

- Check again after some time
💡 Pro Tip:
If everything on your side is working fine (network, SIM, settings), the issue is likely temporary — and it usually resolves automatically without any action.
What to Do If OTP Still Not Received
If you’ve tried everything and the issue continues:
- Contact FAB customer support.
- Visit a nearby ATM or branch
- Try again after some time
These steps ensure you regain access safely without risking your account.
