GMRS freqs are not universal. GMRS freqs in one country could be used for another radio service in another country. For an example, allocated public safety freqs in the US are the same freqs used for business radio services in England.
No country in there right mind will send anything that could benefit the political division or military operation of an adversary. Iran may be in the world of hurt for radio communication or they may think any civilian operation could be considered an opposition force, may take away those gifted radios.
Humanitarian items of medical and food would be a more appropriate. Electronic devices would never be approved by this country, nor they should be approved.
Anyways, regardless of the freqs that could be used for by citizens in Iran, do you really think they would really work? Not a chance in hell they would work with all the electronic jamming going on.
