Mobile VoIP

The main reason to use a Mobile VoIP service is to get access to cheap or even free local and international calling. There are also many other benefits to this service that makes it worth the effort to evaluate if it is the right choice for you.

Mobile VoIP Benefits and Comparison

The easiest way to evaluate the benefits of using VoIP for calling on a mobile device is to compare features. We have created a comparison table that looks at the key differences between making calls using the regular cell phone method, and making calls on a cell phone that is running a mobile VoIP application. Every provider that offers this service seems to offer it in a slightly different way so when we show that a feature is checked, then we mean that it is definitely available from some providers although perhaps not from all.

Feature Mobile VoIP App Cell Minutes
Free VoIP Calling via WiFi YES NO
Monthly Fee Required NO YES
Unlimited minutes YES NO
Uses up Cell Phone minutes NO YES
Uses up Cell Data plan bandwidth YES (3G/4G) N/A
Cheap International Calls YES NO
Free International Calls YES NO
Cheap International SMS YES NO
Virtual Office Capabilities* YES NO
Integrates with home VoIP service YES NO

* Additional fees may be required

Let's go through these features one by one:

Free Calling over WiFi - If your cell phone is connected to the internet via WiFi, then a mobile calling app will automatically use this connection for voice calling. As WiFi is usually free, the calls are free.

Monthly Fees - There are no monthly fees for services that enable VoIP on mobile devices.

Unlimited minutes - A typical cell phone plan costs are structured based on monthly minutes used.

Cell phone minute usage - This calling service will never use up any of your calling minutes.

Data plan usage - This is only applicable if you are NOT connected via WiFi.

Cheap International Calls - One of the biggest benefits over regular cell phone calls is the incredibly cheap international rates that are available by using a mobile app. For more information, consult our article on cheap International calling options.

Free International Calls - Hard to believe but this is actually widely available. This typically involves a bit of upfront planning to ensure that the person you are calling is also setup with the same service and has the application running on their phone or computer. An example of this is the Skype application.

Cheap International SMS - More commonly known as texting, it can also be done up to 65% cheaper than regular text methods. Services such as Rebtel achieve this by creating a local number as a proxy for you to text to and then this local number forwards the text to the international number that is assigned to this proxy number. This saves on the international portion of the text but you are still charged for the local text through your cell phone plan. You can also send texts in this way from a PC in addition to your cell phone.

Virtual Office - This is useful for business people who are on the road a lot as it can effectively give your cell phone a lot of the functionality of your in-office phone and callers will never know that you are out of the office. For more information take a look at our article on why mobile apps are essential for your business.

Home phone service integration - Home phone integration only works if you already have a home phone service powered by the provider that offers the mobile application. It basically means that your home phone becomes mobile when you are mobile and you can answer or make calls from your mobile using your home phone number.

Can I call a landline using Skype?

-> Response: Yes you can call a landline but you need to purchase Skype credit and you are then charged per minute rates (around 2c/min). Alternatively you can pay for an actual plan each month for unlimited calls to the USA/CAN.
