Sigma Box team is a really good team in the gsm world business!! I think, is good pay for activation and packs, that make the difference and give us warranty for a good suport and box, updates and proyects no will dead like other team or boxes! If you no want pay, is very easy, take off the gsm business..... You pay 60usd for 1pack and after unlock 1000..cel phones
