Help me set up my cellular data on my iPhone?

So my iPhone 6s screen completely glitched and got destroyed, meanwhile I got back on my old 5s to use it in the meantime, I can't seem to get my cellular data hooked up, and the Verizon logo (Verizon) won't appear in the top left corner, I'm signed into the same account and everything, not sure what to do, any help?

Have you inserted the LTE SIM card from iPhone 6S to the 5S? If not, do it. Login to your Verizon account and activate the iPhone 5S if you've not done that. Once done, restart your phone and wait for the 5S to be active, might take some time. You can also visit the Verizon store or call them to activate.
