I'll hazard a guess: mobile providers can send a special type of
message (not sure if it would be classed as an SMS) with
Compared to AES-128, AES-256 is 140% of the rounds to encrypt 200% as much
data. So when implemented in hardware, AES-256 is substantially faster.
Excuse me, AES-256 has the same block size as AES-128, that is 128 bits.
It's in fact slower, not faster, and in hardware it also occupies a

AES-256 has a 256-bit key but exactly the same 128-bit block as AES-128
