First of all, the remaining traffic is never deleted.
For example, with the Light plan, which includes 5 GB of traffic, if you have 3 GB remaining at the end of January and renew your subscription, your total traffic for February will be 8 GB โ> 5 GB from the new plan plus the 3 GB carried over from January.
If you do not renew your subscription, any remaining traffic will be frozen until you purchase a new plan. Once a new subscription is activated, the unused traffic will be added to your current plan.
