Will Hi Voicemail save me money?
We've been asked this a lot over the last few years. In short it depends on your carrier and plan.
If your carrier charged you previously to access voicemail, then with Hi Voicemail using spare bundled plan minutes to receive the message and wifi for your data (or bundled cellular data) to download would likely save you some cash.
Check your mobile bill and see if there is voicemail charges to work this out.
