Hi,
I recently bought a Blackberry 8800 supposedly Unlocked from Ebay, and i'm subscribed to Fido,

I inserted my SIM CARD, and when i turned on the device, it showed : INVALID SIM CARD on my screen.
I'm new to this, can I please know and get help concerning on how to use the blackberry on FIDO, and for now i don't need the data services, only phone and SMS should be fine.

I appreciate your help ! thanks !

One, your BlackBerry must be unlocked for use on a carrier other than the one for which it is branded. See our faq on "how do I unlock my BlackBerry".

Good luck.

Two, ensure the SIM card is inserted into the slot the correct way.

I have been there, done that. A year ago, when I got my shiny new unlocked 8800 from the US, I went to insert my Rogers SIM card into it and found it did not work. In the accompanying instruction booklet, there are instructions on how to insert the media card, battery, etc. but nowhere in that manual does it show what orientation the notch is for the SIM card.

Turns out I had it in backwards. If you hold the phone up to a bright light, there is an outline of the SIM card orientation in the black plastic which shows which way it should go but it is very easy to miss, trust me. ;)
