Please give us more details that you get network for a while or not, when you search network manually you get network or not, use Nokia Tool to enable Network Moitor on the phone then use test 01 in Network Monitor to see if your Rx or Tx faulty or just use a sticker when you call 112 and see if its flashing then write another message with details...
