Those who don't mind getting a cheap phone that functions just fine should consider shopping at Walmart, as the retail giant is selling Android phones at such a low price of $10.

While Walmart's deal is sweet, it's good to note that buying LG's cheap Sunrise L15G and Lucky LG16 has a catch. Being a remarkably cheap handset, both of them only have a 3.8-inch LCD with a resolution of 480 x 320 pixels.

They are powered by a quad-core Snapdragon 200 SoC clocked at 1.2 GHz. It also has a 3-megapixel main camera, a micoSD slot and a storage capacity of 4 GB, although only "up to 1.15 GB" is noted to be available for use.

The handsets don't have a front camera, which means it's not great for those who love to take selfies. It does support Wi-Fi connectivity but is not 4G-capable.

As for the operating system (OS), the LG handsets run on a two-year-old Android 4.4 KitKat. There was no mention on the devices' random access memory (RAM) specifications.

The $10 handsets are already discounted by Walmart and may be a deal good enough to get a person a working backup phone, but PC Magazine explained further on what customers need to understand before making a purchase.

The news outlet stated that the devices, being priced so cheaply, are part of a limited promo sale. It is reportedly one of the retail store's strategy, since they are offering free shipping services for purchases of over $50.

Another thing to consider is that the LG handsets are under the U.S. carrier Tracfone, which means that the phone is subsidized.

The device is bound to Tracfone's network and a customer needs to use the phone with the said network for a year before he or she can have it unlocked.

This is not the first time Walmart has offered a phone so cheap. Last year, it sold a Firefox OS phone for only $35, according to Ars Technica.

Meanwhile, making a choice between L15G and LG16 won't make a difference since both devices bear the same specs. Although they don't offer the kind of speed experienced in more expensive mobile devices, they can still be decent buys for those who only want a fully functional, cheap gadget.
