Changing phones

How do I change phones using the same sim card

Something else to consider. Look into your calling plan and the way you are dialing numbers.

Are you on a province-only calling plan? Are you calling from your contact list in which numbers are prefixed by "1"?

What happens when you try to call out?

I think the S3 uses a mirco sim.  If the Galaxy Core is a recent phone then probably a nano sim.  Here is info about diffeent sim sizes.  https://iihelp.iinet.net.au/SIM_card_sizes_explained

Which version of the Core? Core, Core Advance, Core 2, or Core LTE. Not all are fully compatible with PM. Check out your specific phone at https://willmyphonework.net/

My phone is a Samsung s 3 and I am switching phones to a Samsung  galaxy core.

You may need to do a network reset. Since you're not being specific about which phone, we're not clear on the OS version. However, under "system" should be "reset options" with a sub-option to reset "network" or "wif-fi, mobile & bluetooth". 

Note that after resetting your network, you will need to reconfigure all your wifi and bt connections.

Then explaining in detail what steps you took, and what brand and exact model of phone you are using, might help us help you?

What kind of phone?

As @wetcoaster said, it's usually just that simple unless the phone you're changing from is old enough that it uses a microSIM instead of a nanoSIM. In that case, your SIM card may just have a pre-scored punch out to make it smaller. If not, you can try and cut it down yourself (not recommended) or you'll need a new SIM.

Take the SIM out of the old phone, put the SIM into the new phone.

Newer SIM cards are 3-in-1, if you need a smaller size  remove the outer rim.

If you have an old single size SIM you can cut it down, or you can go and buy a  new one and transfer your Public Mobile service to the new SIM number in your self serve account.
