Traffic expiry

Traffic expiry is the rule that decides what happens to purchased but unused gigabytes: many providers void them after 30 to 90 days or at the end of a billing cycle, some roll them over, and a few keep them valid indefinitely. For irregular workloads the difference is the whole bill, because buying a large tier for a lower rate only pays off if the traffic can be used over time.

Pricing All terms

Three policies#

  • Cycle expiry: the allowance resets monthly; unused traffic is lost. Typical of subscription plans.
  • Validity period: pay-as-you-go traffic valid for 30, 60 or 90 days after purchase.
  • No expiry: traffic stays until used. Lets you buy a low-rate tier and consume it over months.

Why it changes the effective price#

A 100 GB purchase at a low rate is only cheap if you use 100 GB before expiry. With no expiry, the tier price is the real price; with 30-day validity, a job that needs 40 GB a month should buy 40 GB tiers, at a higher rate.

How it works at ProxShift#

ProxShift residential and mobile traffic never expires: the balance stays on the account until it is used, with no monthly reset and no minimum monthly spend. Dedicated addresses run for their term and can be renewed.
