I bought Etisalat MF631 hsupa modem yesterday and i'm already using mtn on it. I tried all the unlocking software available to me but none did the magic except dccrap + nokia pc suite. How? I inserted another sim and it prompted for unlock code.
I cancelled the modem window.
I opened dccrap and click on search.
I click on "unlocking". That's it. But i couldn't complete my data connection, so nokia pc suite finished the rest.
