03plus: An IP Phone App for Using Landline Numbers on Your Smartphone

03plus is an IP phone app that allows you to use landline phone numbers on your smartphone without the need for complicated installations. With just a web application, you can obtain fixed landline numbers with area codes from major cities across Japan, such as Tokyo's 03 and Osaka's 06.

Using the smartphone app, you can make and receive calls, as well as send and receive faxes, eliminating the need for a physical fax machine in your office. By installing the app on your personal smartphone, there's no longer a need for a separate company-provided mobile phone. Whether you're on the go or working from home, 03plus is the perfect IP phone service for making calls with a landline number, turning your office into a virtual address.

Signing up is quick and easy through the official website, where you can obtain a phone number in as little as 10 minutes. In addition to making and receiving calls with a landline number, 03plus comes with standard features such as blocking anonymous calls and specific numbers. Optional features include voicemail, after-hours announcements, web phonebook, call forwarding, and internet fax. You can also have multiple users share a single phone number. Internal calls are free, and you can even use the park hold feature.

For those looking to save on outbound call charges, there's an option for unlimited 10-minute calls. Take advantage of the current 0 yen start campaign and try it out for free.
