One of the smart phones I use still functions with a mini SIM card. Recently, that has become an obstacle in my banking activities. But instead of committing myself immediately to drastic solutions and actions, I first rummaged through my pile of retired cell phones. Lo and behold, I found one which can fit in a mini SIM card! The retired gadget even belong to a newer generation in comparison to the one I am currently using.
Placing the ancient SIM card into the younger phone allowed me to install a necessary banking application, which led to the enabling of a security feature required by this specific bank.
A bit complicated, I know. But I have solved a problem by using simpler unconventional steps. The plus side of this is that I even get to revive and reuse an otherwise stored-away gadget.
