Answered question
Is there anyway I can flash without airtime on my line?
Say Y'ello to MTN Beep Service; this service allows you to send a flash call to your loved one (Home and Abroad) when you ran out of airtime. You will be notified via SMS if the person's line was successfully beeped and this service is free. You can make 20 Beep service calls a day. For information on MTN Beep service, please log on to https://www.mtnonline.com/personal/mtn-beep/.
Also, if you are a prepaid MTN Customer, please dial *606# to check if you are eligible to borrow MTN Xtratime and pay later.
You may also dial *133# to send a "call me back" SMS to your loved ones.

You can actually reach out to your loved ones with no airtime on your line via MTN Beep service.
MTN Beep Service is an auto-trigger beep call that allows you to flash your loved ones with insufficient or no credit. This appears as a missed call on the receiver’s phone and the good news is that it is now available for both local and international calls.
Enjoy.
