Most Alcatel handsets are locked from factory

Luckily 90% of them can have the unlock code calculated from the imei

what is the model, if I can I’ll calculate the code for you for free

It doesnt sound like the sim. It is locked onto a carriers network. You have to get that carrier to network unlock it. If you bought it online then that means they never got it unlocked. You could also try a sim card from that specific carrier and hope that it is not blacklisted. Check the imei online and see if it is blacklisted.
