Welcome to the community!
Yes, you will just need to pick up an LTE SIM card for $10 at any of our stores or by ordering it online / via customer service. Following the activation of your LTE SIM, you may need to modify the APN from fido-core-appl1.apn to ltemobile.apn.
Let us know how it goes!
Sorry I didn't reply earlier been away but it sounds like you figured it out. I had to do the same thing, after I bought the LTE card I was going to cut it but there is a store in my area that had a cutter so I just had them cut it to a Micro Sim size. Been working great since then....
