Recently I have purchased the unlocked blackberry 8830 world edition from Wal-Mart-USA in order to use it in India (GSM 900/1800) and they supplied the Verizon wireless balckberry8830 phone.
But I have tried most of the GSM providers in India. But, it is not working in any of the GSM providers in India. It showed “Invalid SIM card”.
I went, to Options/Advanced Options/SIM Card typed mepd. In the resulting list showed the SIM position is active. So it is locked.
In the Wal-Mart web site they are selling unlocked version of BB8830, but they supplied locked version.
