Agreed. Here in VK and I suspect many other places there are few “band tuners” during the week. If someone has alerted and I know they are reliable I’ll try to spend 10 minutes listening out for them - other activities permitting. Week day activators know the value of spots. Some peaks have no phone coverage so the first “by chance” caller if a known SOTA chaser is asked to spot. This will usually bring up the requisite number of callers.
Any phone that can send an SMS can be used to spot and is a worthwhile safety device to have when out in the hills. SMS works at low signal levels but if you have no coverage at all then you are reliant on your radio.
There are popular calling frequencies. 14.310 USB is probably the most popular for 20 m in this region with 14.062 CW for CW buffs. LSB on 7.090 +/- 5 kHz increments and CW on 7.032 ares also very popular.
Calling blind on these is a better option than picking any old clear frequency.
While the above is true for VK/ZL something similar would apply elsewhere I guess.
We all still get failed activation’s. My last one in 2015 resulted in 3 contacts. I did not spot but had alerted.
So reconsider your strategy and have another try is my advice to all. Propagation is down and for QRP and not so great antennas we need to create as many possibilities of success as we can.
Spotting helps the chasers, not just the activators.
