Background

Amidst the recent surge in startup creation, there is a growing need for business phone numbers among a wide range of businesses, including sole proprietors and small and medium-sized enterprises. However, many individuals and businesses grapple with questions such as, "Do I really need a landline number?" "Are mobile phone numbers sufficient?" and "How can I introduce a service while minimizing costs?"

Furthermore, many phone services make it difficult to convey a clear image of actual usage, posing a challenge for potential customers to grasp the service details and application methods when considering adoption.

Therefore, to support businesses in choosing their phone environment during startup and business launch, and to more clearly communicate the features of "Jimuden" to prospective customers, we have produced and released this service introduction video.
