Hmm it seems that it doesn't support your country signal Mhz,go to the page you bought the phone and check this

example
Operating Frequency: GSM
Network Frequency: 850/900/1800/1900MHz

after google what frequency your country supports

you shud unlock that phone see if any phone repair shop in your area supports that phone model.
