Hello what is the difference between N and B band on each devices, btw I'm using SM-S918U1 Factory Unlock S23 Ultra US 5g is working but it's not stable. it appears around 3-5 seconds and turn back to 4G.
"F" and "B" represent international LTE and 5G models, respectively. "E" is associated with Asian markets, while "N" is specifically for South Korea. The USA uses "U," and unlocked Galaxy devices in the United States have an additional character: "U1." Some markets also have variations like "FN" and "FG."
It has the same meaning. For example, n77 is just a short term for NR Band 77. They use the N prefix to make a distinction between 4G and 5G bands as bands like B1 are used in both technologies.
