También, se puede usar esta frase, "I tried to reach him at his number"

This sounds better:

I tried to reach him through his cellphone, but it was disconnected.

In this way you explain how you tried to reach the person - through his cellphone. Also please take note of the consistency of the tenses. It is assumed that the disconnection was known at the time of call. You can use is in this way: I try to reach him through his cellphone, but it is disconnected.
