The first digital phones ran on 56 bit (symmetric?) encryption. They certainty weren't powerful enough to run public key cryptography at safe key sizes, which is needed for secure e2e.

Not at key sizes considered safe today, but 384 bit RSA was considered secure for some uses around then.

The RSA-155 Challenge (512 bits) was not beaten until 1999.
