...i'm sorry if i posted this one on another thread, didn't get much response so i'm posting it again..
...i have a T-mo USA sim, 3 years old...is there a chance that it will be a v1 sim? i don't wanna purchase sim reader/writer and silver sim and later on find out it's not compatible with what i have...
...any opinion is appreciated...
...click the link below to see the image of my sim
...thanks again!

YES!
That is a V1 SIM card! I can totally see it!

Seriously... The only way to know... is with a sim reader/writer.
I just used 100 USD on a sim programmer (Infinity USB Unlimited) + a few silvercards. Then I found out that my Sim card isnt V1...

The best thing you could do is to find out if anyone you know have a sim programmer that you can use to find out if you have a V1 sim card...

thanks iMags!

...i guess that's the only way of finding out...what happened now to ur writer & silver sim? did u return it or sell it?

i can confirm that a sim that i have since 2004 is V1. I was able to clone and use, unfortunately i am not in the states now so I do not know if everyting works when at home network. I am roaming now and it is working fine.

...thanks "nikibs"!
...now it gives me hope that the sim i have is V1, keep us posted when u get back to US!

My Tmo SIM is from 2006 and i don't have the original credit card like holder it came in. Looks like I may be out of luck for this. the SIM does have a few numbers on top- OCS_2.3 does this mean anything?
