Help will this phone work

[kirschman]

I currently have a BLU phone with AT&T and straight talk. I was considering ordering this Amazon.com: Samsung Galaxy S4 I337 16GB 4G LTE AT&T Smartphone (Black): Cell Phones & Accessories When I purchased the BLU phone I had to get the sim card kit to get it working. Am I able to just transfer my sim card over to this phone and be able to get it up and running??

As long as they're the same size it should be fine.
Accessing LTE may depend, however, on whether or not the SIM for your Blu is compatible.

the sim I have in my phone now is a regular size, not the micro. Not sure what size the S4 has. I guess i can purchase a new sim card if needed, just really dont wanna have to deal with straight talks customer service on the phone for an hour.

Im guessing this phone is 4g? Never bought a phone online before so Im trying to make sure I get what I want, thats alotta $$ for me to spend on a phone.
