There are places all over Bali where you can buy sim cards and/or top them up. Ask any taxi driver or local and they'll point them out.
For the price you would be paying to unlock your own phone, you could buy a secondhand mobile in Bali. Prices vary and you'd have to bargain. But cheaper than unlocking or buying on ebay.
