I purchased a new Samsung S7 Edge from Verizon (The best US carrier, I've had em all) and it came with a Nano Sim card installed, I activated it, works fine, but I have a perfectly good Samsung Note 3 and S5 that use a Micro Sims and I would like to have access to use these phones on occasion

Works well fore my note 4

I use t-mobile and the micro tiny sims card worked well and fit perfectly if not a little snug
