The Best Free Cell Phones

Let’s face it: Not everyone wants (or needs) a top-of-the-line super phone with a sky-high price tag to match. Carriers know how to wrangle new customers with reasonable deals. After all, subsidizing the price of a phone is the best way to get you to sign a two-year contract. And if you’re on a strict budget, a free phone represents the best deal of all.

Below we’ve listed the free phones we recommend on AT&T, Sprint, T-Mobile, and Verizon Wireless right now. Although some of these phones were free right out of the gate, others were actually quite expensive when they first came out. The Apple iPhone 4, for instance, is available for free on AT&T, Sprint, and Verizon Wireless. While it doesn’t feature support for any of those carriers’ 4G LTE networks, there’s still plenty to like, from its gorgeous 3.5-inch retina display to Apple’s unsurpassed catalog of apps. It’s a free phone we can wholeheartedly recommend, and now it costs a whole lot less than its initial $200 price tag.

Something to think about: You can’t beat the price of free, but if you’re willing to spend anywhere from $20-$50 dollars, your options become broader. And if you think about it, you’ll probably be using this phone for the entire two-year length of your contract. Spread out over time, even $50 doesn’t seem like such a big investment. Also, keep in mind that you can find some great deals on non-carrier sites as well. We suggest checking out Amazon.com, LetsTalk.com, and Wirefly.com, in addition to your carrier itself. With so many wireless dealers out there, don’t be afraid to look far and wide for the best deal around.

Facebook Saves Developing World Data Plans With More Efficient Android App

Data is expensive and phones have low storage in developing nations like those in Africa, so over the last year, Facebook quietly undertook a massive engineering overhaul of its Android app to make it easier to use around the world. It now starts up 50 percent faster than six months ago, uses 50 percent less data than a year ago, and the download itself is 65 percent smaller since the start of 2014. The updates will make sure more Android users have the latest version of the Facebook app that loads fast even on old devices, and doesn’t burn through their data plans so quickly.

Facebook is reaching saturation in its primary markets. It has 202 million monthly users in the US and Canada, compared to a combined population (including all age groups) of around 353 million. The region has grown just 4 million users since Q2 2013, while the “rest of world” region that includes Africa has added 49 million users. For Facebook to keep growing, it has to court the developing world, where there are still plenty of people without accounts.

But these emerging markets have very different mobile network and device conditions than in Facebook’s home country. Rather than LTE access, high-end smartphones, and lots of iPhones, many in parts of Africa, Asia, and South America rely on low-end Android phones connected to slower networks. That’s why Facebook had to retool its Android app — it’s the way the developing world social networks. facebook-android-clean

So Facebook embarked on a mobile testing trip to Africa last year, as engineering manager Alex Sourov explains in a blog post. “We purchased several different Android handsets to test the latest version of the Facebook app – and the testing process proved to be difficult. The combination of an intermittent, low-bandwidth network connection and a lack of memory space on the devices resulted in slow load times and constant crashes. We even burned through our monthly data plans in 40 minutes.”

Sourov and his team came home determined to make the Android experience better for everyone. “Android’s diversity of devices and networks means more affordable smart phones for more people,” the company tells me. Getting them a better Facebook app could empower them to learn and connect.

The implemented a number of smart hacks to make the app run better under adverse conditions. It shrunk the size of the app by 65 percent by using the Google Play store’s option to offer different Android Application Package files depending on the user’s OS version and screen resolution. This let it cut out code for features if they couldn’t run on a user’s phone anyway.

To make sure the Facebook For Android app was as data efficient as possible, the company experimented with different image compression technologies and decided to switch to WebP. This format’s quality looks the same but requires 25 to 35 percent less data than a JPG and 80 percent less than a PNG file. It also stopped automatically loading images at high-resolutions that permit zooming, and instead now only loads the high-res version if a user wants to zoom. These changes helped make the app 50% more data efficient.

Smartphone costs are coming down in the developing world, but data costs remain high, so these updates could go a long way to making Facebook more accessible worldwide. And while developing markets might not command high ad rates, Facebook has the potential to monetize them through facilitating peer-to-peer payments and striking deals carriers since its apps lure people into buying data plans.
