Installed a SIM card but phone says no SIM card on my sharp fx pro

As far as I know there are two possibilities to get this error message.One is poor signal of that respective network for which you just need to switch OFF and ON your mobile and the mobile will be able to receive the signal from near by tower.You may also get this error message when you are trying to insert a sim other than which the mobile is locked to.To solve this problem you need to unlock the phone from that particular network or use the same sim to which the mobile is locked to.To unlock your Sharp phone you can purchase unlock code from any vendors online like

I have a poor signal how can i make it better nokia 5230 so i can call on my phone

First of all,put the SIM card into another phone which you can be sure that there are no faults with it and check whether you're getting a good enough signal strength than your nokia 5230 phone.
If you're not,then its not a fault with your nokia 5230.
If your area has a poor signal strength from your current service provider,move into another service provider who has more signal strength within your area if you can.

Poor reception

1.Sometime due to bad antena, the signal receiving power goes bad, to confirm this, try another sim card in ur handset.So go to service centre to repaire or change the antena of ur handset.

2. Select network manually.
