You have to go through boost. I tried doing it 3rd party where you send your imei no. Etc, they had no luck and didn't charge me the fee. It was much cheaper, I ended up buying a boost sim to use as second phone.. Defeats all purposes. Min recharge is 30 which six, I'm using my phone now as a MP3 player and YouTube video remote... It's not worth.paying 100, if it was 20 to 30 I'd happily pay. I'm.using a Xperia M.. My other phone a galaxy edge note is busted and I'm on 80 plan other wise I would switch too boost. You might consider using boost other wise.
