You won't get vectors from a non radar airport
It would be interesting how many VFR pilots have managed to get vectors in the terminal environment. My recollection from my VFR flights abroad is "never", though I did readily get them when high altitude enroute (also VFR).
Also, in the international context, ATC's expectation (of
VFR traffic) is that you can locate a VRP. If you cannot locate a VRP, they don't have to do anything. Remember their ICAO English Proficiency only needs to include the standard phrases
