Having lived in Iran, the program is not a UBI, but a "replacement" for the petroleum and energy subsidies that were provided to all. So, instead of the government paying for your gas - which subsidies consumption - the idea is to pay a fixed subsidy primarily to benefit the very poor. This income has a large benefit for the very poor parts of society, but they still have to work to make ends meet. If this amount of money makes a difference to you, you probably have no disposable income. This is more akin to a tax reform than a UBI program, though.
