Yes, you can choose to have a separate InnoCaption account (and InnoCaption number) for each cell phone number that you use. For example, you could have one account for a work phone and one for a personal phone.
In addition, you can also choose to use a single account across multiple devices. Once you have registered an account with InnoCaption, you are able to use the same account login details (cell phone number and password) on more than one device. For example, if you have an iPhone and iPad, you can use the same login credentials for both devices at the same time. Even if your tablet device does not have a cell phone number attached, you can use your InnoCaption account to make and receive calls as long as the tablet has an internet connection. You can even use the same InnoCaption account to log into two different cell phones. When using multiple devices with one account, when you receive an incoming call to your InnoCaption number, all of the devices that you have logged into will receive the call at the same time. You can then choose one device to answer from. Please note that you can only be on a live call with one device at a time using the same account.
