   I am sorry I can't help you directly, but "435Mhz +- 5MHz" has never 
been a
cell band*, in fact it is well within the American 70. CM band. 
(420-450 MHz.)

   It might have been designed as a pager transmitter and some HAM has
adjusted for amateur use.  The manufacturer and model number would be
very helpful in helping you further.
