Te (llamo) llamaré cuando llegue a la casa.
I do not know the reason, but it may be that it is a subordinating conjunction rather than a preposition.
The reason is that in these types of sentences cuando indicates a future event that has obviously not yet happened, so for this forcast we use subjunctive.
However, don´t get so involved in subjunctive that you forget about the meaning of indicative. Te llamo cuando llego a casa is a valid sentence, it just has a different meaning from that of subjunctive use of cuando, which is used unconjugated when we talk about repetitive events, ie: El sol sale en la mañana cuando no hay nubes.
So with the sentence in question, someone is telling someone else: I (always) call you when I arrive home. Obviously, some context would make it more understandable such as the previous sentence being: Why do you worry about me?
Te (llamo) llamaré cuando llegue a la casa.
Why is llegar conjugated? I would leave it in the infinitive form. No change in subject. I call and I arrive.
Ok, this is the thing:
te llamo/llamaré cuando llegue a casa = I will call you when I get home
te llamo cuando llego a casa = Say you are enumerating/listing things to do...
It's all about context, not fog. ![]()
Llegar would be conjugated for the same reason you would conjugate both verbs in the sentence "voy a mi casa y yo como." (I go to my house and I eat). The reason being that they are two separate clauses. It may be the same subject, but every verb clause needs to be properly conjugated.
As to the CORRECT conjugation, its been noted that it is subjunctive. The reason would be that its not a set time and can vary. Future + cuando = subjunctive in every case as far as I am aware.

Although I always get negative feedback when I say I don't like the "change of subject rule" I will say so again.
I have always seen a clause beginning with cuando having a conjugated verb:

I do not know the reason, but it may be that it is a subordinating conjunction rather than a preposition.
If something requires a conjugated verb, and requires subjunctive, it will require subjunctive even if it doesn't have a subject change.
Example from the link:
Llegaremos cuando debamos y no antes. We will arrive when we should and not before.
If I did not want to conjugate, I would use a preposition:
Te (llamo) llamaré al llegar a la casa.
Upon arriving, rather than when I arrive. Note in English, I also need a conjugated verb with when, but not with upon.
Would the Spanish be the same if we change
"''I will call you when I get home''
to
"''I will call you IF I get home''
It means i will call you when i get home
