i wrote to sammy Germany and they wrote back that my phone (which i bought used from ebay) is locked by Vodafone UK
and i should contact them..
"Smartphones that you purchase a wireless service provider, are often provided with a network lock. This is not about the regional EU-SIM card lock.
An activation code for the network lock, you can only ask directly to the intended wireless service provider."
will try another service but maybe i will have to pay online for some unlocking service
any recommendations of any internet based unlocking sites for euro phones. ?
