What Should I do if EG SIM Card doesn't work or I can't connect to Wi-Fi?

Your sim still doesn't working when you replaced EG sim card in your phone and followed user guide to start up it. 

What your phone says that 

1) you see a message like “No Service” and 
     there is no "Olleh" displayed, 

     so you cannot make calls, your phone can not connect  
     to Wi-Fi, nothing similar connected. 

2) you see a message like “3G or wi-fi sign”  and 
    there is “Olleh” displayed,
