If you frequent the unsecured Wi-Fi in airports and coffee shops, your connection to the internet is not as safe as you might hope. With a virtual private network, or VPN, such as VPN Unlimited from KeepSolid, you can be sure that your browsing is encrypted and private. This service offers inexpensive, flexible subscriptions, as well as many of the advanced security features we usually see in far more expensive products. Its iPhone incarnation is attractive and easy to use. When you add solid speed scores and specialized streaming servers, VPN Unlimited is a very attractive service. Along with NordVPN, it's our Editors' Choice winner for iPhone VPN apps.

What Is a VPN?

When you switch on your VPN, it creates an encrypted connection between your computer and the VPN server, which serves to foil hackers or even government snoops trying to eavesdrop on your activities. From the server, your web traffic travels off into the public internet, but your actual IP address remains hidden. Data-hungry website advertisers see the IP address of the VPN server instead of your own. A VPN can even help protect against your ISP harvesting your data—something new for us all to worry about.

How a VPN Works
PCMag Logo How a VPN Works

You should use a VPN as often as you can, but especially when your iPhone is connected to a public Wi-Fi network. When you hop on an unsecured network at the airport or coffee shop, you have no way of knowing whether the network is what it claims to be. Your iPhone is constantly looking for known networks, and techniques are available to fool it into thinking it has found one. Instead of a convenience offered to thirsty customers and weary travelers, the network could be a trap, created by a hacker looking to intercept your data.

VPNs can also disguise your actual location, which is why journalists and political activists operating in countries with restrictive internet controls use them. This has a fringe benefit for the average user: You can use a VPN to view region-locked streaming media content, such as the latest TV shows from the BBC. Note, however, that some streaming services like Netflix block VPN users. Note, too, that you may be violating terms of service or even local laws if you use a VPN in these ways.

There's a good chance that you've never used a VPN before. If that's the case, don't worry! We've got a whole feature on how to set up and use a VPN.

Features and Pricing

VPN Unlimited offers six pricing plans, giving you lots of choice over how much you pay and how often you're billed. The cheapest plan costs $4.99 for seven days, good for a quick jaunt abroad. Paying month-to-month goes for $9.99, a bit under the current average, which is around $10.50 per month. You can get a discount by paying for a longer period at once. It costs $18.99 for three months, $59.99 for a whole year, or $99.99 for three years. Note that you pay all fees in full at time of billing, and the company offers a seven-day money back guarantee.

If you're thrilled with VPN Unlimited and want to hedge your bets about internet access in the afterlife, you can opt for the Infinity Plan, which is a 100-year subscription for $149. KeepSolid, the developer behind VPN Unlimited, kindly notes that the company will "gladly extend this period by your request." You can buy these, or any of VPN Unlimited's other plans, with credit cards as well as Amazon Pay, Bitcoin, Payment Wall, and PayPal. You can also pay through the iTunes store, of course.

KeepSolid VPN Unlimited Plans

Note, however, that KeepSolid only lists the monthly, yearly, and Infinity plans on its website. For the other options, you must download the free client and make your purchase there. It's a bit tedious, but the flexibility of these plans makes it well worth the trouble. Even after a few small price increases, it's still very affordable and the most flexible pricing of any VPN PCMag has yet tested.

Although VPN Unlimited is inexpensive, it has more features and options than most of its higher-priced competition. For example, at the time of this review, VPN Unlimited provides servers across 70 locations. These include many often-overlooked regions, such as Africa, the Isle of Man, Mexico, South America, and Turkey, to name a few. The company used to offer servers in Russia and China, but no longer. That's not too surprising, considering that VPNs have been under pressure in those regions. NordVPN, Private Internet Access VPN (for iPhone), and TorGuard have well over 3,000 servers—far more than KeepSolid's 400 or so. By the numbers, NordVPN is the most robust VPN service we've tested.

Want to go cheaper? There are numerous free VPNs available. Of particular note is TunnelBear, which is extremely easy to set up and use. Its free version maxes out at 500MB of traffic per month, however.

Unlike TorGuard VPN, which specifically aims to support BitTorrent and P2P services, VPN Unlimited only allows file sharing on five servers (California, France, Luxembourg, Ontario, and Romania). VPN Unlimited also has special Streaming servers, available specifically for high-speed video streaming, even after greatly reducing its total server offering. Co-Editors' Choice NordVPN also offers a video streaming server, but goes further with a VPN server that also connects to the Tor anonymization network, as well as a double-encrypted server.

Power users looking for a personal VPN server in the country of their choice, or a static IP address that is (allegedly) not associated with proxy services will appreciate that VPN Unlimited offers these rare options. Personal IP addresses are available in Canada, France, Germany, India, the Netherlands, the UK, and the US. An IP address in any of these locations costs $14.99.

A Personal Server offers users improved speeds, since you won't be sharing it with other VPN users. Many of these cost $21.99 per month, and have a bandwidth limit of 1TB per month. You can also opt to purchase plans with more bandwidth. The advantage is that a "clean" IP address is less likely to be blocked by other services (such as Netflix). TorGuard VPN (for iPhone) also offers static IP addresses, and includes other add-ons such as access to a high-speed 10-gigabit network. VPN Unlimited is the only service we've seen that offers server rental.

Also in the category of rare features is something called KeepSolid Wise, which disguises VPN traffic as HTTPS traffic. This is designed for use in countries where access to the free internet isn't available, and where the use of VPNs is blocked. TunnelBear VPN (for iPhone) has a similar feature. For Android, Windows, and Linux systems, VPN Unlimited uses the OpenVPN protocol, and uses IKEv2 on macOS. The iPhone edition now uses IKEv2 by default, and provides OpenVPN, IPSec, and KeepSolid Wise as options. That's a rarity in iOS VPNs, because Apple applies extra vetting to apps using OpenVPN.

KeepSolid goes beyond basic VPN protection in several more ways. For example, it offers browser extensions that provide VPN security from within Chrome and Firefox. For full details on these advanced features, see our review of KeepSolid VPN Unlimited.

Your Privacy With KeepSolid VPN Unlimited

Although the point of a VPN is to protect your privacy, using one requires that you trust the VPN company. That's because the VPN company can have the same level of insight as your ISP and could do all kinds of unpleasant things if it isn't an ethical company. It's also important that a VPN company retain as little information about you as possible. Otherwise, that information could identify you online and defeat the purpose of using a VPN in the first place.

KeepSolid has a clearly written privacy policy. It does a good job explaining exactly what information it gathers and how it stores that information. We like it when a company makes this kind of effort to be transparent. It says the company "does NOT collect and log any user activities while using any of their VPN services, except the total amount of web traffic for each session and session dates." That's pretty typical for a VPN service.

KeepSolid VPN Unlimited Main Window

Our company contact explained to us that none of the information logged by KeepSolid would allow the company to match IP addresses or DNS requests to a customer's online activities. It does note how many devices are connected for each user, and it keeps encrypted information about those devices. This last point is a little disconcerting. Other services simply limit the number of simultaneous connections and don't profile the exact devices that connect. We'd like to see KeepSolid move to an even more anonymous method for enforcing its policy on simultaneous connections.

Not long ago, some VPN companies chose to make some extra dough by injecting ads into users' web traffic. A company representative confirmed to us that KeepSolid VPN Unlimited does not do this, nor does it profit from the sale of user data.

The company has offices in both the US and Ukraine, and operates under US legal jurisdiction. This means it is not subject to any specific data retention laws. However, the representative pointed out that KeepSolid's zero logging policy means that, in any case, it would have precious little information to retain or hand over to law enforcement. We don't believe that we can make a judgment on how safe a VPN company is based solely on its location, and we encourage you to inform yourself and go with the company you feel you can trust the most.

Recently, KeepSolid introduced the Censorship Test feature. This scans your internet connection and looks for services and websites that may be blocked in your geographic region. For example, our US-based scan looked at 45 websites and found them all available. You can opt to send KeepSolid an anonymized version of your scan, which the company says will be available in aggregate at www.censor-check.com. Sending your data will also earn you a free day of VPN access, but you can only submit one scan per week.

Hands On With VPN Unlimited

In addition to the iPhone app reviewed here, VPN Unlimited supports Android, Linux, macOS, and Windows with native clients. As with most leading VPN services, VPN Unlimited lets you connect up to five devices simultaneously. You can add an additional device for 99 cents per month, five devices for $2.99 per month, or 10 devices for $5.99 per month. If you've got a big family or a lot of devices, it's an excellent option.

Installing the app on an Apple iPhone SE was quick and easy in our testing. Conveniently, the app preselected the best server for us. You can also view a list of recommended alternate servers, and KeepSolid displays the current load on each. For example, it recommended a server in Australia with 5.6 percent load. Our nearest server, in California, displayed a 71.4 percent load.

As with PureVPN (for iPhone), you can run a ping test to check latency for each location. Gamers will appreciate this feature, because high latency translates into connection lag that could get you fragged.

KeepSolid VPN Unlimited Locations

Like NordVPN (for iPhone)(3 Months Free & Up to 74% Off 2-Year Plan at NordVPN), VPN Unlimited displays a world map showing its server locations (though it lacks the sailboats and submarines that brighten up NordVPN's map). You can tap a dot on the map to view its precise location, and tap again to connect with that server.

The app doesn't offer (or need) many settings. As noted, you can choose the OpenVPN or IPSec protocol, or the KeepSolid Wise feature that makes VPN traffic look like HTTPS traffic. But that's about it for VPN settings.

As noted, Netflix does its best to block the use of VPNs for streaming content locked to another region. Previously, when we tried to stream with the iPhone VPN active, Netflix simply returned a network error. This time around the connection went through. It's a cat and mouse game, with Netflix evolving its detection system and VPN companies finding new ways around it.

Good Speed Test Results

Regardless of the VPN service you choose, you're likely to see an impact on your web browsing experience. More latency and decreased upload and download speeds are typical. This is especially true when connecting to a far-flung VPN server.

When we test mobile VPN apps, we deactivate mobile data, and then connect to Wi-Fi. That's because a Wi-Fi network offers more repeatable test results than a cellular network can, and because insecure or malicious Wi-Fi networks are much more prevalent threat than complex cellular attacks. Most people use a VPN to protect their Wi-Fi traffic.

To get a sense of the impact using a VPN will have on internet speeds, we perform a series of tests with Ookla's internet speed test tool. (Note that Ookla is owned by PCMag's publisher, Ziff Davis.) We average these results and then find a percent change between when the VPN is in use and when it is not. Of course, networks are notoriously finicky things, so your mileage may vary.

VPN Unlimited turned in a decent performance in our tests. It increased latency (the time required to ping a remote computer and receive a response) by 20.8 percent. That's right in the middle for current iPhone VPNs. CyberGhost VPN (for iPhone)($2.03 Per Month + 4 Months Free (84% Off 2 Year Plan) at CyberGhost VPN) only increased latency by 3.7 percent; with IPVanish latency increased by 79.5 percent.

As mentioned above, unless you're playing an intense first-person shooter, you probably won't notice any increased latency due to use of a VPN. A drag on download speed, on the other hand, could be a big problem. VPN Unlimited slowed downloads by 21.3 percent, very close to the average score for current products. That is, with the exception of AnchorFree Hotspot Shield Elite (for iPhone), which actually increased download speed by 76.1 percent. We omitted this outlier when calculating the average.

All recent products except Hotspot Shield put a drag on upload speed, but none of them by a huge amount. Hotspot Shield increased upload speed slightly; PureVPN came in second with just 2.4 percent slowdown. VPN Unlimited slowed uploads by 5.8 percent, just slightly better than Golden Frog VyprVPN (for iPhone)'s 5.9 percent. But even the worst score, shared by Private Internet Access and TorGuard, was just 8.5 percent.

A Fine VPN

When we test VPN services, we're looking for speed, flexibility, and balance between excellent performance and advanced features. KeepSolid VPN Unlimited does well in all these regards. Its pricing scheme is inexpensive at the usual monthly subscription cycle, and with subscription periods as short as one week, VPN Unlimited can be available whenever you need it. Add to that BitTorrent support, a well-designed client, specific streaming servers, browser clients, and advanced security features, and you're looking at an all-around winner. For all of this, VPN Unlimited earns our Editors' Choice award for iPhone VPN apps, an honor it shares with NordVPN.

About Neil J. Rubenking

Lead Analyst for Security

When the IBM PC was new, I served as the president of the San Francisco PC User Group for three years. That’s how I met PCMag’s editorial team, who brought me on board in 1986. In the years since that fateful meeting, I’ve become PCMag’s expert on security, privacy, and identity protection, putting antivirus tools, security suites, and all kinds of security software through their paces.

Before my current security gig, I supplied PCMag readers with tips and solutions on using popular applications, operating systems, and programming languages in my "User to User" and "Ask Neil" columns, which began in 1990 and ran for almost 20 years. Along the way I wrote more than 40 utility articles, as well as Delphi Programming for Dummies and six other books covering DOS, Windows, and programming. I also reviewed thousands of products of all kinds, ranging from early Sierra Online adventure games to AOL’s precursor Q-Link.

In the early 2000s I turned my focus to security and the growing antivirus industry. After years working with antivirus, I’m known throughout the security industry as an expert on evaluating antivirus tools. I serve as an advisory board member for the Anti-Malware Testing Standards Organization (AMTSO), an international nonprofit group dedicated to coordinating and improving testing of anti-malware solutions.
