The method still work but its hard to find codes nowadays that's what I believe. Its been hard on me to find working code that don't require credit check or rps payment. But if you find a working code you can bank a lot of money off it. What do I mean by that 1 sim card can probably make you $100 + easily. How? just use that unlimited sim cards to fill out your offer. Like ringtones or offer that got to do with the phones. Where you just enter your number they text you a pin and just confirm it. These offer pay about $10 per lead. Do this in about ten different offer and network you can bank off. Most of these offer will charge your wireless account which you don't have to pay so everything will be should be ok.
