Sim life

[Finwizzard]

If I do not renew my sim plan at the end of the month, how long does the sim stay valid? That is, can I renew it within 6 months say, for it to work again?

As @JJP2 says, but you should receive an email reminder 2 weeks before the end of that period.

You have 180 days to re-activate any paused plan
