htc - 9500 networking

[beonfocus]

Hi

I leave in israel, i have htc-9500 (wallaby) and i installed the unlock
software from this site.

In Israel, we have 2 main companies that use GSM network
the first is "CELLCOM" and the other is "ORANGE".

when i put SIM CARD of Orange, everything was ok !
when i put SIM CARD of Cellcom, the mobile can not find the network.

both companies use GSM network with 900/1800 band.

What is the problem ?
Why is it work with one company and did not work with the other ?

Thank you very much

Well may be its still locked to ORANGE or your other sim is no good.

Hard to tell based on what little info you have given.
