Hello, i Have Iphone that use in Portugal with Vodafone Operator.

He works perfectly but this weekend i went to spain (used roaming) and when i returned he replaced the "operator" name to orange instead of vodafone.

I used another sim card of another operator (optimus) and replaced fine the name, but when i use my sim card vodafone he puts the Orange Name on the operator space.

Can you help me out how i can replace the Orange to Vodafone?

Thanks in advance
