No, you emphatically are not. The criteria is membership in the armed forces: https://ihl-databases.icrc.org/en/customary-ihl/v1/rule4 Had it been otherwise, practically everyone working for the Israeli state would also be a "valid combatant target". Including reservists since they are also "under the effective command" of the IDF. I have no idea who carries these pagers and neither does you, so I'll refrain from speculating.
In regular armies, activated reservists are valid combatant targets. Reservists become civilian, under the principle of distinction, when they are deactivated and fully integrate into civilian life. More applicably to the situation with Hezbollah, which is an irregular army, functional criteria apply; meaning, very roughly and in my paraphrase, "is some aspect of the armed wing of Hezbollah your day job?"
I don't know that we disagree much here. We both agree that simply because Hezbollah operates a school does not distinguish the employees of that school as combatants. There are civilian combatants; for instance, whether or not your yourself were ever going to take up arms in Syria, if you work in a Hezbollah arms depot or weapons factory, even if you're just counting the bullets, you're most definitely a combatant. It depends.
You're refraining from speculating on something I am clearly not refraining on. I get that. I am (much) further out on the limb than you are. When the evidence shows I'm way off on this stuff, I'll absolutely say so. The big place where our premises differ is: I believe Hezbollah pagers to be military equipment, and you believe random Lebanese people with weak associations to Hezbollah might carry them as well. I'll say right now that is not a crazy point of view; it's just one I don't currently share.
