Hi there,
with the actual firmware on RUTX11 i can not switch the sim. sim1 is selected as default but it always connects with sim2 that was default before. also had no internet with established connection yesterday an no hint what was causing the trouble.
please be more precise with your firmware updates, it sometimes seems that no one is really checking or having plan what development strategy is planned. Problem with language set to german is causing troubles again, that was fixed in between previous versions.
seems like a bit amateur development for such important things as firmware and stable and working product!!
regards
volker
