Hi,
May I know what do you mean by this please?
Your purchased socks is NOT under a time limit like daily or monthly. They will NEVER expire unless you use them.
Also are you planning to give some vouch copies to trusted members as your account is Brand New?What are the locations of the proxies?
It simply means that if you purchase (example) the 10 socks package and only activates 1, you can come back in 1 month and use the rest of the 9. There's no expiration time for your purchased plan.
