Is it not recognising any sim or is your mobile locked with any particular network?If the mobile is not recognising any sim...then probably there is a problem with the mobile..take it to a nearby mobile shop and check whether the mobile is in good condition.If the mobile is locked with any particular network it will not accept other networks.It will only work with the locked network.It will not recognize other sim cards.If that is the case then you can unlock the phone to make it accept other networks.
