Why do I get a "No Service" message on my phone and how I can fix this problem?

I get a message I'm not saying my phone service since the previous night, which means they can not send texts, make calls or access the Internet. Me with Orange and my phone is not unlocked. Is there anything I can do to fix it, or should I wait to Orange solved the problem. Thanks in advance for any help you can give me

Try taking your battery aa minute wait, then put it back and restart the phone. If this fails, there is probably a problem with the network being down or for some reason Orange have SIM card blocked.
