My Iphone 4 displays "no service" message in top right hand corner!

My Iphone wont pick up reception in areas where others will, it randomly picks up signals in some parts of my school and some streets in my town but it will still only have 1 bar and will only be there for about 30 seconds! I bought the Iphone off Ebay and it says it was unlocked, even if it was locked it says in settings>general>about it says that its carrier is Optus 13.1 and I am trying to use my Amaysim sim card which I am pretty sure runs through optus!

well i did yes, but i fear i made a mistake. Under the heading for 'iPhone Number' i mistakingly left in the sample number that was there...is there a way to like unregister the phone and start the whole process from scratch?...
