ATT's unlimited data, ain't unlimited????

AT&T's unlimited data plan ain't unlimited. A number of customers think they are being screwed by ATT

  White man speaks with forked tongue??? Nope, maybe they were thinking of ATT with their misleading advertizing, or maybe even out right false advertizing!

In their advertizing ATT tells customers they can have unlimited data on their cell phones, but when they reach a certain point they slow down the data transmission so it take 99 times longer then it normally takes.

AT&T customers surprised by 'unlimited data' limit

By PETER SVENSSON | Associated Press

NEW YORK (AP) — Mike Trang likes to use his iPhone 4 as a GPS device, helping him get around in his job. Now and then, his younger cousins get ahold of it, and play some YouTube videos and games.

But in the past few weeks, there has been none of that, because AT&T Inc. put a virtual wheel clamp on his phone. Web pages wouldn't load and maps wouldn't render. Forget about YouTube videos — Trang's data speeds were reduced to dial-up levels.

"It basically makes my phone useless," said Trang, an Orange County, Calif. property manager.

The reason: AT&T considers Trang to be among the top 5 percent of the heaviest cellular data users in his area. Under a new policy, AT&T has started cutting their data speeds as part of an attempt to manage data usage on its network.

So last month, AT&T "throttled" Trang's iPhone, slowing downloads by roughly 99 percent. That means a Web page that would normally take a second to load instead took almost two minutes.

AT&T has some 17 million customers with "unlimited data" plans that can be subject to throttling, representing just under half of its smartphone users. It stopped signing up new customers for those plans in 2010, and warned last year that it would start slowing speeds for people who consume the most data.

What's surprising people like Trang is how little data use it takes to reach that level — sometimes less than AT&T gives people on its "limited" plans.

Trang's iPhone was throttled just two weeks into his billing cycle, after he'd consumed 2.3 gigabytes of data. He pays $30 per month for "unlimited" data. Meanwhile, Dallas-based AT&T now sells a limited, or "tiered," plan that provides 3 gigabytes of data for the same price.

Users report that if they call the company to ask or complain about the throttling, AT&T customer support representatives suggest they switch to the limited plan.

"They're coaxing you toward the tiered plan," said Gregory Tallman in Hopatcong, N.J. He hasn't had his iPhone 4S throttled yet, but he's gotten text-messages from AT&T, warning that he's approaching the limit. This came after he had used just 1.5 gigabytes of data in that billing cycle.

John Cozen, a Web and mobile applications designer in San Diego, hasn't been throttled yet either, but he's been so disturbed by a warning that he's "almost scared to use the phone," he said. Complaining to AT&T got him nowhere, and now he's looking to switch to another carrier.

"I don't think two to three gigabytes is an exorbitant amount," he said. "Really, I'm just looking at pictures and text once in a while."

AT&T spokesman Mark Siegel said that as of last summer, the top 5 percent of data users were using 2 gigabytes of data per month. But he also said the company doesn't actually throttle all of the top 5 percent "unlimited" data users. Last month, the figure was only 0.5 percent, or about 200,000 people, he said.

That's because AT&T only throttles users in areas where the wireless network is congested that month, Siegel said.

Siegel also pointed out that aside from moving to a tiered plan, "unlimited" plan users on the cusp of being throttled can use one of AT&T's 30,000 Wi-Fi hotspots, where usage is unmetered.

The unlimited plan worked fine for AT&T a few years ago, when the iPhone was new. The company had ample capacity on its network, and wanted to lure customers with the peace of mind offered by unlimited plans. Now, a majority of AT&T subscribers on contract-based plans have smartphones, and the proportion is growing every month. That's putting a big load on AT&T's network.

The limited data plans force subscribers to keep an eye on their usage, so they don't overwhelm AT&T's network. Verizon Wireless has adopted similar plans. But the two companies differ in how they manage their remaining "unlimited" subscribers.

Verizon doesn't slow down the "5 percent" unless the cell tower their phone is connected to is congested at that moment, and it slows them down by the minimum amount necessary. By contrast, once AT&T has decided to throttle your phone, it will be slow for the rest of the billing cycle, even if it's 3 a.m. and there are no other cell phones competing for the capacity of that particular cell tower.

Verizon's measures have drawn few complaints, and indeed, may have gone unnoticed even by the "5 percent."

T-Mobile USA is up front about the level it starts throttling at: 5 gigabytes. AT&T subscribers have no idea if they might be among the top 5 percent until they get the warning, which is soon followed by throttled service. While Trang was throttled at 2.3 gigabytes, he knows other iPhone owners who are using 5 or 6 gigabytes per month with impunity.

"It seems very random," Trang said.

Sprint Nextel Corp. is hanging on to unlimited data plans without throttling, alone among the "Big Four" national wireless carriers.

Tallman sees few prospects for a lawsuit against AT&T. The company is still providing unlimited data usage to throttled customers, even if the speeds are so low as to make the phone useless for anything but phone calls and text messages. The company made no promises that "unlimited" data would always be coupled with high speeds, he notes.

"They just guaranteed the highway. They didn't guarantee the speed limit," he said.

Honest, it's unlimited data - Kinda, sort of !!!

An Update for Our Smartphone Customers With Unlimited Data Plans

Dallas, Texas, July 29, 2011

Like other wireless companies, we're taking steps to manage exploding demand for mobile data. Many experts agree the country is facing a serious wireless spectrum crunch. We're responding on many levels, including investing billions in our wireless network this year and working to acquire additional network capacity. We're also taking additional, more immediate measures to help address network congestion.

One new measure is a step that may reduce the data throughput speed experienced by a very small minority of smartphone customers who are on unlimited plans - those whose extraordinary level of data usage puts them in the top 5 percent of our heaviest data users in a billing period. In fact, these customers on average use 12 times more data than the average of all other smartphone data customers. This step will not apply to our 15 million smartphone customers on a tiered data plan or the vast majority of smartphone customers who still have unlimited data plans.

Starting October 1, smartphone customers with unlimited data plans may experience reduced speeds once their usage in a billing cycle reaches the level that puts them among the top 5 percent of heaviest data users. These customers can still use unlimited data and their speeds will be restored with the start of the next billing cycle. Before you are affected, we will provide multiple notices, including a grace period.

This change will never impact the vast majority of our customers, and is designed to create a better service experience for all.

The amount of data usage of our top 5 percent of heaviest users varies from month to month, based on the usage of others and the ever-increasing demand for mobile broadband services. To rank among the top 5 percent, you have to use an extraordinary amount of data in a single billing period.

There will be no changes for the vast majority of customers. It's not how much time you spend using your device, it's what you do with it. You can send or receive thousands of emails, surf thousands of Web pages and watch hours of streaming video every month and not be in the top 5 percent of data users.

Typically what puts someone in the top 5 percent is streaming very large amounts of video and music daily over the wireless network, not Wi-Fi. Streaming video apps, remote web camera apps, sending large data files (like video) and some online gaming are examples of applications that can use data quickly. Using Wi-Fi doesn't create wireless network congestion or count toward your wireless data usage. AT&T smartphone customers have unlimited access to our entire Wi-Fi network, with more than 26,000 hotspots, at no additional cost. They can also use Wi-Fi at home and in the office.

The bottom line is our customers have options. They can choose to stay on their unlimited plans and use unlimited amounts of data, but may experience reduced speeds at some point if they are an extraordinarily heavy data user. If speed is more important, they may wish to switch to a tiered usage plan, where customers can pay for more data if they need it and will not see reduced speeds.

But even as we pursue this additional measure, it will not solve our spectrum shortage and network capacity issues. Nothing short of completing the T-Mobile merger will provide additional spectrum capacity to address these near term challenges.
