My dad gave me his old phone (Iphone 5S with MTS) and however my SIM card from my phone (Galaxy S5 with MTS as well) doesn't fit. It's too big for the slot. I know that people change phones all the time. Do you have to get a different SIM card from MTS? I thought I was good to go as long as both phones were on MTS.

Unfortunately Apple or at least the iPhone 5s uses a "nano" sim while other devices use micro or macro sims. There is lots of info on the web about them if you use those search terms and even tutorials on how to cut them down to fit. You can do that at your own risk or go to a connect store and tell them what you need (less risky). don't honestly know if there is a charge - perhaps someone will pop in here on that.

Great question!!

MTS shows on the other charges web page a cost of $10 for new or  replacement  sim cards.

Hey Colin,

Jason is right and the iPhone 5s will need a different SIM than the Galaxy that you were previously using. They do use a 'nano' SIM card. Different handsets as mentioned have different SIM's in order to run properly. Based on how the iPhone's are set up they do require a smaller SIM card in general than other devices.
Pop down to an MTS Connect store - there is a $10.00 charge to purchase a new one. They'll associate it with your cell phone number and you'll be up and running in no time.

Please let me have any other questions.

Just to add my understanding of the "risky" part of trimming your own SIM card down is an error can render the card useless and require a replacement. The process is unlikely to cause any damage beyond the SIM card. That said, it is possible, but unlikely, you have data saved on your SIM card that you would want to keep.

Yes the risk is mainly to the SIM card, not to the phone.  I trimmed mine down by printing out a cutting template then trimming mine to match.  One important thing to note is that the nano SIM is ever so slightly thinner than a micro SIM card.  I need to use tweezers to pull my trimmed card out of my phone, because the fit is a bit snugger than a true nano SIM would be.

One site I was looking at last night recommended using sandpaper to try and thin out the sim to fit once its been trimmed.   I think I'd spend the $10 to get a new one.
