How can I activate my iPhone 4?

OK SO YOU NEED TO READ THIS ! My father bought me an iPhone 4 from France and he used it a little bit there, when he came back in Romania ( my country) he throw in the junk the sim card, box etc and he came in Romania just with the wall adapter, iPhone, headphones, usb cable. When I've seen it i was something like OMG OMG OMG ! and I've connected it to my computer and restored it... Now the big problem is that the phone is stuck in the activation screen and I don't have any ideea how can I use it without the original sim card. Now my question is there any way for Apple to make my iPhone read my sim card that I use in this country? I have talk with a lot of people on how can I unlock my phone but I don't wanna use any jailbreaking because I am a fair user of the Apple devices and services and now I am so dissapointed because I can not use my phone 😢 Thank you for the help!!
