Only vodafone sim card working another sim card not working
Phones often carry what is called a "Sim Subsidy Lock." Which in plain words means that the phone is locked to only allow usage with one companies SIM cards.
There is a company called Davinci Team that can unlock the phone for use with another company's SIM card, but they charge about 50 euros for this service.
