Airtime and data bundle expiry - How does it work?

Airtime, data or SMS bundles have different expiry rules, as determined by each mobile network. This may change from time to time. 

When choosing airtime amount or data bundle to recharge with on SIMcontrol, the expiry period is shown next to each option.
