Compare the Best Mobile VoIP Providers of 2025

Mobile VoIP providers are the bridge that allows you to combine cellular and VoIP technology. With the explosion of Wi-Fi and powerful 4G LTE, and soon to be 5G, smartphones, VoIP for mobile phones has become a popular alternative for long distance and international calling.

Mobile VoIP providers offer two basic types of service, based on how the VoIP service is run: software-based mobile VoIP (which can allow you to connect via cellular phone to a VoIP provider's network) or hardware-based mobile VoIP.

Software-Based Mobile VoIP

Mobile VoIP providers use your cell phone as a SIP trunking station. If you're already paying for data through your cellphone provider and you're already paying for VoIP from your VoIP service provider, mobile VoIP means you don't have to pay anything extra. Just download the softphone from your VoIP provider.

Software-based mobile VoIP providers rarely, if ever, charge for calls within their network. Usually, mobile VoIP providers have a debit-based system: you deposit a certain amount of money to your account and they charge that account for the off-network calls you make. Remember, calls within the network are free.

Since software-based mobile VoIP provider services can be downloaded, they run on computers and smartphones. As 3G coverage improves, 4G connections bring faster connection speeds, and Wi-Fi hotspots increase, mobile VoIP software will become more and more widely-used.

Mobile VoIP Apps

VoIP applications for your cellphone are becoming more common. VoIP providers may include a free app for download with your phone service, or providers may be entirely based around softphones and phone apps.

Skype, among others, has a free app for mobile phones and tablet computers. You can make calls to other Skype users for free (except for the data usage on your phone) or you can call other phones with Skype credit. Many other mobile VoIP providers have the same terms.

You need a data connection to use apps like Skype. You can either get data from Wi-Fi, or from your cellular plan's data. If you need a valid United States cell phone plan, check out Wirefly's plan comparison tool.

Local Access Mobile VoIP

Some mobile VoIP providers like Rebtel use local access numbers for the both your origin and destination you want to call, allowing cheaper, local minutes for both parties.

While Rebtel's main feature is the array of phone apps, the same service has international phone calls from its website. You sign up and give Rebtel your phone number and the number you want to call. Rebtel gives you a unique local number for the contact, which you can call from the phone you signed up with. You pay for the local call to whatever phone service you currently have, and a small per-minute rate to Rebtel for the international part of the call.

Hardware-based Mobile VoIP: Bring your own phone.

We're far enough down the page. We can let you in on a secret (well, sort of):

Most IP phones "work" as mobile VoIP devices. Since they are frequently provided and programmed to work with the VoIP provider managing your system, you can unplug them and take them anywhere. The number will still be the same (since it is registered to your phone). Literally, you can just take your phone with you. It's one of the reasons why virtual numbers are so valuable.

However, we should mention that using your VoIP phone in this way can cause major problems for your e911 service, since your e911 is registered to a specific location. Just don't dial 911 when you're travelling with your VoIP phone.

How Does Mobile VoIP Work?

There are several methods to turn a mobile phone into a VoIP device; in almost all instances, you will end up using a program that uses a session initiation protocol (SIP) to route your calls through the Internet. SIP is the standard protocol for VoIP. An alternative protocol is UMA, or Unlicensed Mobile Access Generic Access Network, which was developed specifically for mobile networks and Internet telephony.

For the most part, mobile VoIP apps use softswitch software and SIP to code and deliver phone calls over IP.

Softswitch Mobile VoIP

"Softswitch" refers to the software that the phone companies and VoIP providers both use to route calls. With the mobile VoIP software that VoIP providers offer, you get a more compact version of that softswitch software. This software either directs you to the person you are calling, if they're on the same software network. Otherwise, the software redirects you to the mobile VoIP provider's own softswitch, which eventually sends the call through the public network to the person you are calling.

In this case, you would not have to pay for the first call (since the call says on the same network and the call doesn’t really have to do anything) but you would have to pay for the second call (since you access the local phone network).

What You Pay

You pay nothing extra to use mobile VoIP if you have VoIP service and cell phone service with data. You save money because you pay VoIP prices for your minutes (which are usually unlimited). If you are calling on your VoIP network, those VoIP minutes that you're using are probably free - if they’re not, get a new VoIP network. If you call someone else on the same VoIP network, that should also be free.

Prices for international calls depend on your VoIP service. You will either pay a low per-minute rate or have minutes included for select destinations.

What do I need for mobile VoIP to work?

Mobile VoIP requires a few things:

wireless Internet
a smartphone
a mobile VoIP app

Wireless Internet

Believe it or not, wireless Internet is the biggest limitation for mobile VoIP. There are two choices: Wi-Fi hotspots, which are generally free, and 3G and 4G networks, which are not.

Wi-Fi hotspots are free but small; you can't take them with you. However, using the wireless network at your office alongside your mobile VoIP apps mean that you can get VoIP calls for free. Since Wi-Fi hotspots are based on a local wireless network (complete with wireless Internet), they don't have issues with call quality.

3G and 4G networks are not free but they are larger and more mobile. Furthermore, 3G networks do not always offer a consistent connection speed. 4G networks, which are faster and slowly becoming more prevalent, will make connection speeds more consistent for mobile VoIP.

Cell Phone

You will need an Internet-ready smartphone to use mobile VoIP. You will also need a data plan to use VoIP. You can compare cell plans at Wirefly if you do not currently have one.

Mobile VoIP App

You need to make sure you have a VoIP provider - or access to a VoIP provider - that has a mobile VoIP app.

We say access to a mobile VoIP app because not all VoIP providers offer their own, proprietary mobile VoIP application. Furthermore, some instances of mobile VoIP use softphones on a computer. Instead of using a cell phone, the software 'turns' your computer into a phone. Some VoIP providers have partnerships with other companies that create proprietary mobile VoIP apps, which you can then use with the first company's VoIP service.
