At least in Germany we have a grid of Basestations which offer their RTCM 3.1/3.2 Data via NTRIP which is called SAPOS. As there are huge differences between different states at least in some of them its for Free. https://sapos.de/ https://zentrale-stelle-sapos.de/produktinformation-2024-01/ Comparing to Northrhine-Westfalia https://www.bezreg-koeln.nrw.de/system/files/media/document/file/geobasis_rb_sapos_nutzerinfo_varianten_eps_heps.pdf Where it says that the NTRIP caster for NRW is free of charge for real-time applications. So - there are possibilities to use that with an RTK enabled Chipset without having your own base station.
