I've just done a sim swap between o2 sims. My questions are: 1) should I wait until the old one is not working before putting the new one in the phone? Also my old one was on 'pay as you go' and the new one is on 'pay monthly' kind of service. 2) Do I need to contact o2 to cancel my 'pay as you go' service or it is going to happen automatically?
