If you're a Smart Prepaid or Smart Postpaid subscriber registered to mobile Internet offers or combos, you may regularly check your volume allocation balance through text.
To check your active subsriptions and/or the MB allocation left in your package, text BAL to 2200.
For some packages, you will also receive an SMS notification once your volume allocation is nearly used-up.
Most smartphones have built-in data usage monitoring applications. Some applications will notify you once youve reached a specified data usage threshold.
