On the subject of sim card, usually you need to pay a small fee of 2,000 rupiah when you top up your sim card in Batam.

Next time you're there, try topping up at Alfamart. This apply to 100k top up. They don't charge you the 2,000 rp fee. Instead, you get a 500 rp discount too.

Not a big amount 2,500 rp. But, do this 10 times and you just saved enough for a simple lunch.
