That is correct.
However the lowest GSM frequency was 300Mhz, so there is still quite a lot of bandwidth there (if I'm not mistaken to a theoretical maximum of 600Mbit/s for a 2 level signal, though in practice quite a lot less as this are radio-waves rather than signals in circuit lines, so encoding schemes have to be disgned for a lot more noise and other problems).
Anyways, the point being that the right encoding scheme can extract some Mbit/s from even the 300Mhz band.
