AT&T

AT&T Mobility will soon be dedicating a portion of its spectrum to an LTE air-to-ground network, keeping customers connected in-flight. The service is planned for launch in late 2015. Airline passengers will be able to keep in touch with reliable, high-speed data service via Wi-Fi at 35,000 feet.

Currently, Gogo offers in-flight Wi-Fi services for air travelers across the US. The company has fitted thousands of aircraft with its technology, however its stock took a dip after the announcement from AT&T. The planned network will also provide improved connectivity for aviation customers, such as better cockpit communications and crew services.

Reduced pricing is the name of the game as AT&T continues to revamp its mobile offerings to battle the competition. Single-line data plan customers are the latest to benefit, as the company is slashing the price of its 2GB data plan. Subscribers can save $15 over the previous offering, with the new plan going for $65 per month.

In addition to 2GB of data, the single line plan includes unlimited voice calling and text messages, unlimited international texting, and 50GB of cloud storage. Users can even add a second line to share the 2GB data pool for an additional $25. This prices the 2GB data plan with two lines at $90 per month.

Now AT&T Mobile Share plan subscribers can send unlimited text, picture or video messages overseas. 190 countries are included in the new offering at no additional charge. The move by AT&T comes hot on the heels of similar plan changes by T-Mobile.

This addition to Mobile Share plans became effective on February 28, and will take effect on existing subscribers’ accounts automatically. While this is a great new feature for those with contacts overseas, only phone to phone messaging is included, with 70 countries limited to text only.

Competition between wireless carriers gets hotter every day, and now AT&T has rolled out brand new Mobile Share Value Plans for families. Both existing customers and new subscribers are eligible for the plans, which can save AT&T customers on older plans significant coin. Of course, those who still have unlimited data will need to abandon this privilege to switch plans.

Basically, for any Mobile Share Value Plan with a 10GB or larger shared data bucket, each iPhone on the plan is only $15. This means 10GB with four smartphones clocks a monthly cost of $160. Besides sharing the data among devices, personal hotspot tethering is included along with unlimited voice calling and text messaging.

Often one family member on an AT&T Mobility wireless plan is an early adopter, and must have the latest iPhone the minute it's available. Standard two-year contracts exceed the typical iPhone upgrade cycle, which is where a line swap comes into play. Staggering upgrade eligibility around 12 months apart means that someone on the plan gets a new iPhone every year.

Officially, upgrading on an eligible line, then swapping the new device to another line on the same plan is called a "cross upgrade". Cross upgrading from the iPhone 5 to the 5s can be achieved without even contacting AT&T, although to match the phone numbers to the correct device a quick call to customer service (611) is recommended. AT&T condones the practice of cross upgrading, as long as the wireless plan bill is in good standing and there's a line currently eligible to upgrade.
