@Shaw : as above from Meow except really actually 120 days. You pay, you have an active plan for 30 days, then you don't pay, you have 90 days to reactivate. So you pay every ~4 months. But in your case you'll be fine. If you have a balance of more than your plan cost then you'll also need to use the Lost/stolen function to suspend your account so it doesn't renew from that available balance.
There's no strategy for suspending before your 30 days paid term as there is no pro-rating here. So if you don't have enough balance then just toggle off autopay and remove the card (just in case) and the account will suspend for lack of payment. The 90 day clock starts. Reactivate a day or three before then though in case of any difficulties. But again in your case you'll be back by then.
Edit: @HALIMACS : Not quite. Resuming service after the already paid 30 days will do nothing. A new 30 days has to be paid to reactivate. Resuming before those 30 days will just start it up again and go on for the remainder of the already paid 30 days.
