Hello, today i bought a pre-owned blackberry bold 9780. It was originally from rogers. But unlocked. When i got it i put my Fido sim card in. It worked. But now i did factory reset to delete all the old data. When i put in my sim card. It says searching for network. Then if goes to SOS. I don't get any reception. I even put in a rogers sim card and same thing. Can anyone help me fix this problem? I also updated the os and still does not work.
