lebanon has an economy that's currently in shambles, and its never been known for its productive capacity. even if they wanted to start making simple comms devices it might rely on infrastructure that they can't invest in, and take tech/capital they have not accumulated

it would be more realistic for them to receive it from the iran but there might be political hurdles to this and it would end up costing the iranians as hezbollah can't be expected to pay much for it
