Hi, I go through AT&T and I always buy unlocked GSM phones from asia. I recently purchased an LG SH490 (AKA LG Makeup). It required a hypersim to work it so I cut my simcard and paired it with the hypersim, turned it on and it worked. Well, it worked for an hour then it started saying "location update failed". So after working with it for a while, I decided to buy a new hypersim, when I got the new hypersim and paired it with the simcard this time, it says "INVALID USIM". I am desperate to get this phone working, does anyone have any clue as to what I can do to get this phone to work, and why it worked for an hour and mysteriously "lost location update"?

Re: INVALID USIM LG Makeup with Hypersim
It was from Cyon in South Korea. No, I do not have access to the filesystem.
