Anton Sheikh-Fedorenko, There are quite a few PEMFs that don't work on my phone. I can't find the logic in which ones work or not. At first I thought they were all RIFE ones, but that is not true. I am using some without any problem and others just don't transmit at all. We discussed there EBV virus PEMF a few weeks ago. I did everything you recommended, but it was no use.
