If the Voice Roaming add-on is exhausted, roaming usage will begin to deplete any available in-package Voice Roaming bundle, assuming that the in-package bundle is applicable to the roaming destination. If the latter is fully depleted or the in-package roaming bundle is not valid in the roaming destination, out of bundle roaming rates applicable to Post and Pre-Paid Plans respectively will apply. Visit https://bmobile.co.tt/mobile/international-calling-roaming/#voice-data-roaming for details of these rates. Alternatively, a customer can choose to purchase the Add-On again.
