You can easily track your Blackberry Internet service usage via text message or by dialing a code. You will be able to know the expiry date of your BIS and also your BIS data balance. Below are ways you can check the expiry date of your MTN BIS, Glo BIS, Airtel BIS and Etisalat BIS.
==> Text STATUS to ‘’ 21600 ’’ to check expiry date of MTN BlackBerry® Service
==> Text STATUS to ‘’ 440 ’’ to check expiry date of Airtel BlackBerry® Service
==> Dial *228# to check expiry date of Etisalat Internet Service. NO CODE to check Etisalat BIS status for now. Please, if you know it, kindly share with me.
==> Text STATUS to 777 to check the expiry date of Glo BlackBerry® Service
I hope this helps…
