There are no additional charges, fees, penalties, costs for allowing your plan to lapse into suspension (non-payment). And again there are no charges for reactivating it (when payment is accepted). Along with no charges for the time your service was suspended, Day 1 of your next 30-day (or 90-day or whatever) prepaid plan cycle begins the moment payment is accepted and your plan is reactivated. (Sometimes, rarely, it doesn't reactivate automatically, you have to login to Self-Serve and click the Reactivate Plan Now button. And if you have no way to login to your email then you'll get locked out of your account by the EverSafe 2FA "protection".)
The only "penalty" on a suspended plan is that it doesn't collect any bonuses. No Rewards and no Points while it's not in service. No AutoPay bonuses (obviously). No days counted towards Loyalty bonus. No bonuses from Referrals. No bonus awarded for Community activity.
Some of us deliberately allow our plans to languish in suspended status while we go on vacation or whatever. Because there's no additional costs attached to that and not paying a plan you're not using saves money.
A plan will remain suspended for 90 days. After that point, it is automatically terminated, everything is lost, no refunds of any kind. (If your account, promo, plan, add-ons, rewards, points, phone number, SIM are worth keeping then don't allow your plan to go without payment this long.)
