Thanks, but the reseller told me that the period changes expired. Anyway, it took me 2 and half month aprox. waiting to get the cellphone. So I would have to consider about 5 month to get a another one? (2 1/2 month to send ,2 1/2 to get)...and I would have to buy another while I wait... Can you send me another cellphone, and when I receive it I'll send you my cellphone back. At least this work with one sim card, so I won't have to buy another while I wait.
Help please, I don't want to lose my money.
Thanks
