We provide professionally printed beginner guides for iPhone and Android smartphones. Our guides are written specifically for seniors and first-time users — not reprints of manufacturer PDFs, but original books created by experienced instructors who understand the challenges new smartphone users face.
OTC Ltd has been providing printed manuals since 1978. We've served over 300,000 customers in more than 110 countries, delivering over 240,000 printed manuals. In 2025, we began creating our own original beginner guides — the books that should have come in the box.
