Why bother? Even using only alphanumeric characters (I've counted 62 characters) there are more than 10^216 possible keys [1]. That means that somebody would want to break this system and would be sending to you 1 message per second it would require him about 3*10^207 years just to reach 10% probability of sending correct key. (Or about 10^216 years to get 0.5% probability). That will never happen. And I think that you'll get suspicious receiving long meaningless messages all these years. (Also phone will quite likely to become too old to use with cellular networks by that time.
