Loosing signal after 20 seconds with Gevey sim

[pastarojna]

I have Iphone 4 with 4.2.1 and 3.10.01
i got this sim (Gevey) and it works for about 25 seconds and i'm able to make calls with T-Mobile, but shortly after that the phone drops the signal...
Any ideas what the problem is?
thanks

Go to T- mobile and get a new sim, it should fix the problem.
