Hey @Jeeta1542 and welcome to the Community.
I'm sorry to learn about your phone.
I took care of removing your sim card number from your post. This is a public forum and we wouldn't want everyone to have access to this information.
You can register your new SIM card using My Account on fido.ca or at a Fido store.
From your online account, you can simply click on UPDATE SIM CARD to do the change.
And in the section MY PLAN you will see all the features of your current plan. From there, you can click on CHANGE PLAN to modify your price plan.
I hope this helps
