If *116# fails on your phone — a known compatibility issue on some older Android devices — du’s backup isn’t another USSD code. It’s an SMS with an unusual keyword that works precisely because it bypasses USSD technology entirely.
Quick answer
Dial *116# — your Du number appears instantly as a flash message.
When *116# doesn’t work
Send “NUMBER” to 1355, or send “getmymsisdn” to 9296. Both trigger an automated SMS reply with your registered number — reliable specifically because SMS delivery doesn’t depend on the same phone-level USSD support that occasionally fails.
Checking your phone’s own settings
On iPhone: Settings → Phone → My Number. On Android: Settings → About Phone → Status → SIM Status → My Phone Number. This only works if your SIM has properly transmitted the number to the device — new SIMs sometimes haven’t yet.

Troubleshooting
*116# returns "service not available" error
Some phones have compatibility issues with USSD codes. Use the SMS method instead: send "NUMBER" to 1355 or "getmymsisdn" to 9296. You'll receive your number in a reply SMS.
Du app not showing my number
Log out and log back into the du app. If your number still doesn't appear, the app may need an update. Check Google Play or App Store for the latest version of the du app.

Frequently Asked Questions
Does checking my number cost anything?
No, *116# and SMS to 1355 are both free.
Can I check my number if the SIM isn't activated yet?
No — complete SIM activation at a du store first.
Does *116# work on prepaid and postpaid?
Yes, on all du SIM types.
Why does the SMS method work when *116# fails?
It uses standard SMS technology rather than USSD, which sidesteps device-specific USSD compatibility issues.
What if my phone's own settings don't show a number?
The SIM may not have transmitted the number to your device yet — use *116# or the SMS method instead.
