I called T-mobil and they Have no idea whats going on... Anyone have this problem? It searches for the network. ??I am super confused

Your profile indicates an 8830 with Verizon. Is that the phone you are trying to use a TMo SIM in?

Won't work in the US. Yes the 8830 is a world phone and can use SIMs, but the GSM function won't work in the US. Only outside this country.

As above, if the device is a Verizon 8830, then it is CDMA only in North America, meaning since it is a Verizon device, it can only work with Verizon in North America, Outside of NA, if the SIM is unlocked, you can use your T-Mo SIM, otherwise Verizon also offers a SIM for the GSM side.

The GSM frequencies are not compatible with US GSM freqs.

In order to use your SIM, you will need a Blackberry from T-Mo or an unlocked one from ATT or another GSM carrier.
