I just received my Solartoh today (thanks Dirk!), but unfortunately I have the exact same problem I had with my Diptoh, and same problem Clovis had with Solartoh: no network at all when mounted. I had no issue at all the days before with my prototype Toholed (not the same plastic) and my official TOHs. I removed my Solartoh, and pouf, back to 4G network. :/
