In the (hopefully) hypothetical situation that my phone is unfixable, what model(s) might people recommend as a replacement?

All I know about what I want in a phone, honestly, is "Android", "under $100", "unlocked and takes the same SIM card as the current phone" but I'm not sure what size SIM card it is other than not a full-size one (prooobably micro? not sure), "microSD card slot", and "doesn't have ridiculous low internal storage after installing five apps". Which is approximately the order of priority, too.
