BlackBerry 8830

how to Unlock this phone with IMEI?

You would have to purchase the unlock code from a third party unlocking site. Since there is a cost to even us suppliers, you would have to pay for the code.

Once the codes are generated, unlocking sites are charged a marginal fee by their suppliers.

Please note: The 8830 will not work on North American carriers since it is a dual band phone. Dual band phones will only work on the carrier that it is locked to and European and Asian carriers.
