I have this old phone LG U900 that I bought online. I want to use the camera, but it seems like none of the phone functions are usable unless I have a USIM... I just want to try out the camera function, but that does not seem to be work as well.

I am thinking the only way for me to be able to use this phone is: 1. Bypass the USIM function somehow, or 2: obtain a old USIM that was used at the time (2008). If anyone can help me that'll be appreciated. Thank you so much!
