Hi, I need to switch SIM card size after getting a different phone. I've already purchased the right size. The question is how do I make the actual switch? I find two options: 1.Use the transfer SIM option under self serve or 2.Perform new SIM activation and transfer my number over. I know there is a $20 bonus credit on the new SIM card. Would I still get that if I choose the transfer SIM option?
