Is Wi-Fi Calling Safe? (Part III)

Public wifi networks are hotspots for hackers trying to steal information from people like yourself.

What are the security concerns related to Wi-Fi calling?

When you send data by Wi-Fi, the security of your info is at the mercy of the network. Public Wi-Fi networks are sanctuaries for phishers and others who lie in wait for the chance to latch on to an unsuspicious user’s connection and steal their personal info. 

If you were to use a Wi-Fi calling app that did not correctly encrypt your data while on an unsafe public network, you would be wide open to information thieves.

Even if you’re using a secure network, you’re putting faith in your cellular carrier. Big-name carriers encrypt voice data so it can’t be accessed by outside parties. Though, one weakness in the flow of information is all that’s needed. 

In 2013, it was discovered that T-Mobile’s WiFi calling feature didn’t properly validate the security certificate on the server-side, creating a chance for a cyberattack. This kind of attack entails hackers making a fake security certificate and tricking the service into believing it is connecting with the proper target.

How can I protect myself?

Fortunately, the inherent risks linked with WiFi calling don’t mean you have to remain clear of this money-saving, convenient technology. Consumers can take steps to protect themselves against unsecured networks and unexpected security failures by using a product such as Hotspot Shield.

Hotspot Shield works by making a Virtual Private Network, or VPN, through which your data passes. You might recognize VPN technology as something used by employers to let remote workers access the secure company network. 

However, it has become a standard solution for savvy users who want to guarantee their data privacy on a daily basis. Also, you won’t have to fight with key fobs and complex software installations like you might have done with a corporate VPN. With Hotspot Shield, making your own VPN is a simple as downloading a file.

Hackers can listen to your conversations.

Is WiFi Calling Safe?

First, the good news: Yes, WiFi calling is safe, even though your data (your voice) is being sent over maybe unsafe WiFi networks. That’s due to the fact your mobile carrier encrypts your voice, including when it’s sent over WiFi networks. Therefore, even if your voice is sent over public Wi-Fi hotspots, it’s being encrypted by your cell phone provider, making it useless to Wi-Fi hackers.

However, a few voice over-Wi-Fi apps bypass your mobile carrier and therefore might perform no encryption. If you are using one of these apps and your phone is connected to a public Wi-Fi hotspot, you can be in danger of being listened to by Wi-Fi hackers.

So, if you are using a voice-over-Wi-Fi app on your phone, be safe by using a VPN. VPNs encrypt all the data coming out and, on your phone, including your voice.

Wi-Fi Calling is the next great thing for your mobile phone, so be sure you are making the correct call by safeguarding your private phone calls with a VPN.

 What are the advantages of making calls over Wi-Fi?

One of the largest appeals of Wi-Fi calling is that it offers an alternative to cellular technology and can save you money. For folks who struggle with choppy cellular coverage, either because they reside in a rural area or because they just ended up with a bad combination of geographic area and carrier, it’s amazing news. Wi-Fi calls frequently don’t count against your designated number of cellular minutes, so you can talk as long as you like over a Wi-Fi connection without fretting about extra charges.

What are the disadvantages of Wi-Fi calling?

Mobile carriers are still working out the kinks. If you’re on a call while in transit and your Wi-Fi signal drops, the call could be dropped as well while your phone attempts to connect to a cellular network. But the largest disadvantage is the possible security risk.

Is Wi-Fi Calling Safe? (Part I)

Some phone’s can make phone calls through wifi networks. But, how private are your calls?

You may have heard that the new iPhone 6 supports making phone calls over WiFi networks. Using WiFi networks to make calls is the next great thing for mobile phones.

Though, how safe is it to make phone calls with public WiFi hotspots? Are your calls being encrypted? Should you take any necessary steps to safeguard yourself from WiFi hackers?

Welcome to WiFi Calling

Using WiFi networks to make mobile phone calls is referred to as WiFi calling. WiFi calling is the technology that lets packets of data from your cell phone be carried over the Internet and then put back into your cellular network.

This is different from VoIP services such as Skype, which also uses the web to make phone calls due to the fact that with WiFi calling, you can use your cell phone.

Folks are enthusiastic about WiFi calling. If you use the web to make phone calls, those minutes don’t count against your mobile plan. Also, it lets you make phone calls if you are outside your mobile provider’s coverage area.

The technology is not quite perfect yet. There are some problems when a phone goes from a mobile network to a WiFi hotspot. Calls could be dropped. Still, the possibility is there for using WiFi networks in the near future for many cellphones.

Using an App for Wi-Fi Calling

If your phone or carrier doesn’t support Wi-Fi calling, you could always send texts and calls via an app such as Google Voice, Facebook, Line, Skype or one of the numerous other calling apps that could be downloaded onto a cell phone. Remember, you’ll still have to have a data connection such as a carrier plan or Wi-Fi connection.

Wi-Fi calling is usually safe, even though your data is being sent over perhaps an unsecured Wi-Fi network. It is safe since the mobile carrier usually encrypts your voice data.


Should I Go with a Laptop or a Tablet (Part II)?

Tablets are a lot lighter than laptops.


Size is possibly the biggest reason to go with a tablet instead of a laptop. Tablets are around the size of a small pad of paper and weigh less than two pounds. Most laptops are way heavier and larger. Even one of the littlest ultraportables, the Apple MacBook Air 11, weighs over two pounds and has a profile bigger than that of several tablets.

The main reason for the bigger profile is that the trackpad and keyboard take up additional space. Laptops that include more powerful components that need more power and cooling are even bigger. Due to their smaller weight and size, a tablet is much easier to take around than a laptop, particularly for travel.

If you don’t desire the extra power or other features that take up more space, tablets are the way to go.

Battery Life

Because of the low power requirements of their hardware components, tablets are built for efficiency. In fact, a big part of a tablet’s interior is taken up by the battery. On the other hand, laptops use more powerful hardware. A laptop’s battery takes up a way smaller percentage of the space required for its internal components. Thus, even with the higher capacity battery provided by laptops, they don’t run as long as a tablet’s battery.

If you’re looking for the longest battery life, tablets are the true winner.

Storage Capacity

In order to keep the costs and size of tablets down, manufacturers depend on new solid-state storage memory to store data and programs. While this technology has the possibility to deliver faster access and low power usage, it has one huge disadvantage: the number of files it can store.

By comparison, many laptops still use customary hard drives that hold way more. The typical budget laptop comes with a 500 GB hard drive. Both tablets and laptops include features such as microSD cards or USB ports that make it simple to add external storage.

If you need to store a lot of documents, applications, or other data, laptops are your best bet.

Should I Go with a Laptop or a Tablet (Part I)?

Tablets have become popular because of their portability but laptops have a lot of good features too.

Tablets have gotten popular due to their easy-to-use interfaces, portability, and the vast range of functions they deliver. In some ways, the best tablets can replace a laptop for computing on the go. But is a tablet really the best choice over an ordinary laptop? Laptops are also portable yet can be used for a bigger range of tasks.

There is no one correct answer. The better device for you is based on what you mainly want to use it for.  Below are some of the differences between laptops and tablets to see which of the two might be a better choice for you.

Input Method

The clearest difference between a tablet and a laptop is the absence or presence of a keyboard. Tablets depend completely on a touchscreen interface for input, which is okay when you basically want to drag, point, or tap to move around an application. It can be more difficult, though, when you have to input text, like within a Word doc or email message.

Since tablets don’t have keyboards, users have to type on virtual keyboards that have different designs and layouts. Most folks can’t type as accurately or fast on a virtual keyboard. 2-in-1 designs offer a detachable keyboard that might improve the ability to type text. However, these models still fall short of the laptop experience due to their smaller size and more restrictive designs.

Tablet users can attach an external Bluetooth keyboard, but doing so increases the costs and peripherals that have to be carried with the tablet, making it less portable.

Laptops are better for those who write a lot, while tablets are great for those who do more point interaction.

Stand-Alone Device

If you can only afford one device, there’s no question about it: you should buy a laptop. Whereas a tablet does some computing functions very well, a laptop is a completely self-contained system that you can use confidently for loading programs or data onto and backing it up.

What Makes AirPods So Great (Part I)?

Air Pods have become a hit at Apple, but what makes them so popular?

Debuted in 2016, Apple’s AirPods are highly regarded as one of the company’s best products in recent years. The AirPods provides portability, excellent battery life, simple charging, easy connectivity, and unparalleled Bluetooth range.

AirPods are so popular that Apple still has difficulty keeping them in stock at times. Even now, it’s not unusual to see AirPods everywhere, including in films, on the street, in TV shows, and everywhere else you look.

If you’re new to AirPods, thinking about buying a pair, or just want to pick up some new tips, this article is for you.

What are AirPods?

AirPods are Apple’s totally wire-free headphones, which look a bit like the Apple EarPods from older devices, but cable-free. AirPods have Apple-designed tech inside such as a special wireless chip called the W1 or H1 (based on the version), an accelerometer for gestures, dual optical sensors, dual beamforming microphones for Siri and phone calls, as well as a second accelerometer for speech detection.

AirPods come with the AirPods charging case, which is used for both storage and charging purposes so the AirPods don’t get lost. The charging case is around the size of a pack of dental floss, so it fits easily into a pocket. A lightning port at the bottom lets the AirPods and the case is charged with the lightning cables you already own. Also, the wireless charging case lets you charge with a Qi wireless charger.

How many versions of AirPods are there?

The AirPods were first up for sale in December 2016 and were refreshed in March 2019, so there are two versions of the AirPods: the original AirPods and the second-generation AirPods. Though both versions are referred to as “AirPods,” but there are some obvious differences between them.

The second-generation AirPods, or AirPods 2, have an enhanced H1 chip instead of a W1 chip. The H1 lets the AirPods switch between your devices twice as fast and connecting a phone call is 1.5x faster. The new AirPods have the same typical battery life, however three hours of talk time instead of two. You won’t see any design differences between AirPods 1 and AirPods 2 since they’re identical.

What’s New at Apple

Apple has some impressive products and you’ve come to the right place to discover what’s new.

In a typical year, Apple has around four events. There’s usually a spring event in March, the Worldwide Developers Conference in June, a September event that’s concerning the Apple Watch and iPhone, and sometimes an October event if there are new Macs or iPads debuting in the fall.

2019 iPhones

In 2019, you can expect three new iPhones, similar to the 2018 lineup. Rumors state there will be one LED model (XR successor) and two OLED models (XS and XS Max successors) with no serious design changes. However, there might be new colors and a new frosted glass back for the next-generation iPhone XR.

The iPhone XS and XS Max successors will have a new triple-lens camera that could provide ultra-wide-angle shots for the first time, while the iPhone XR will use a new dual-lens camera system. There are some rumors indicating Apple may use USB-C for the new iPhones, but it’s looking like the company plans to stick with lightning.

Also, you can expect an A13 chip along with quicker WiFi and LTE, bigger batteries, and a cute new bilateral wireless charging feature that will let the 2019 iPhones wirelessly charge other devices such as the AirPods with wireless charging case.

There is no information on what Apple is planning to call its 2019 iPhone lineup. Yet, given that there’s no clear follow-up to the iPhone XS, XS Max, and XR names, most rumors refer to these devices as the “2019 iPhones.”

Apple Watch Series 5

Rumors suggest the Apple Watch Series 5 will have a new ceramic casing design, indicating a return of the Apple Watch Edition alongside the typical stainless steel and aluminum casing options. Besides this, we don’t have a good amount of information about what to expect from the Apple Watch in 2019.

Also, new health features have been talked about for years like non-invasive blood glucose monitoring. A micro-LED display is a possibility along with solid-state buttons.

The Best Bluetooth on the Market Today (Part IV)

If you like to talk, then you need a Bluetooth headset.

Plantronics M70

Big features, a small price

The Plantronics M70 is the successor to the popular M55, and similar its forbear, it is an affordable headset, but you get plenty for your money. While it doesn’t have a maximum build it’s quite comfy to wear, it supports voice commands for real hands-free use and the sound quality is excellent, especially when aided by the built-in noise-canceling tech. Also, the M70 has a DeepSleep mode which activates when it’s detached from a paired smartphone for 90 minutes and leaves it with up to five months of battery life, but just bring your phone within range and it will swiftly wake up again.

Jabra Wave

The top Bluetooth for chatterboxes

With a talk time of over eight hours, the Jabra Wave is a Bluetooth headset that just keeps going and going, making it the perfect choice if you’re going to be away from a charger for a long period of time. The fairly large size means it’s not the most discreet of headsets, but it’s a worthy trade-off for all that battery life. Also, it has strong audio quality and is good at muffling noise, especially wind. Add to that easy pairing and the capability to connect it to two devices at once and the Jabra Wave is a solid choice.

The era of the traditional Bluetooth headset is coming to an end. If you look at Amazon or any other big retailer, you see that the single-ear headsets of 10 years ago have quickly evolved into stereo Bluetooth headphones, practically all of which include microphones for you to make calls with. While there are still mono headsets on the market, many of them are either no-name products, several years old or no quality.
