I'm wondering about the life expectancy and use of a SIM card. Currently, i have two phones (HTC One and Nexus 4) that i will swap back and forth between once or twice a month. I'm curious as to how long my SIM card will last with being removed and inserted back and forth between phones. Every once in a while i will notice that i have no service, and then switch back to full bars (2G, 3G, or LTE) while i'm still in the same position/spot. I'm wondering if my SIM card is beginning to wear down. Would it be easy to go to a T-Mobile store and get a replacement SIM?
Thank you.
