Pros & Cons

    • With HSDPA 7.2 for download and HSUPA for uploads, the AirCard 881 will likely be the fastest cellular PC Card available.
    • Newer laptops may not have a PC Card slot.
    • AT&T; hasn't turned on HSDPA 7.2 and HSUPA in most places yet.

In the arms race for the fastest wireless Internet, the latest weapon is HSUPA, a system that should boost wireless uploads on AT&T's network to speeds from 400 to 800 kilobits per second (Kbps). The first card to support HSUPA, the Sierra Wireless AirCard 881 is a strong performer for both uploads and downloads on the road.

The AirCard 881 is a one-piece device that easily fits into a laptop's PC Card slot. A set of small, unobtrusive LED lights on the top of the card show whether it's in 2G (slow) or 3G (fast) mode. AT&T's Connection Manager software supports Windows XP and Vista. Sierra offers a free program to support Mac OS, but as no Mac laptop in almost two years has had a PC Card slot, the value of this card for Mac owners is almost nonexistent.

The AirCard 881 actually has two new technologies. HSDPA 7.2 is meant to boost download speeds beyond existing HSDPA 3.6 cards like our Editors' Choice AirCard 875U. Meanwhile, HSUPA should bust the 384-Kbps upload barrier of existing cards, potentially doubling upload speeds. That puts AT&T's system on a par for uploads with Verizon and Sprint's EV-DO Rev A, and potentially much faster for downloads than the competition.

Carriers have to upgrade their towers to HSDPA 7.2 and HSUPA, though, and it looked like that had yet to happen during the week I was testing in New York City. I got very similar speed results on the AirCard 881 and 875U. The 881 did come out faster on 22 of 40 download tests, but that's a very narrow margin, and the differences in average speed were so small as to be meaningless. I got an average of 1.1-Mbps downloads and 300-Kbps uploads with both cards—very good download speeds, but speeds that are possible with HSDPA 3.6 and without HSUPA. Reception was also similar enough to the 875U not to matter.

Like all AT&T cards, the AirCard 881 requires a data plan. We recommend the $60-per-month unlimited-use plan. That's the same price that Sprint and Verizon charge for high-speed data card plans. The AirCard 881 roams internationally, though you'll pay through the nose to have it do so: $20 per megabyte in most countries. If you're going to do any overseas roaming, get an international data plan. The $109.99 North America plan gives you 100MB per month in Canada and Mexico, with additional data at $5 per MB. The $139.99 Global plan extends your 100MB to many European and Asian countries, with additional data in those countries at $5 per MB. If you're not in high-speed range, the card (like all AT&T cards) drops to the slower EDGE network.

That said, there's no downside to getting the Sierra AirCard 881, as long as you have a laptop with a PC Card slot. With its next-generation technologies, it's only going to get faster. While I was writing this review, AT&T introduced the USBConnect 881, a USB modem with the Sierra AirCard 881 hardware inside. This would be the best option for Mac users and those without PC card slots, but until we test that one, the AirCard 881 gets our Editors' Choice for the best high-speed Internet solution on AT&T's network.

My Experience

I'm that 5G guy. I've actually been here for every "G." I reviewed well over a thousand products during 18 years working full-time at PCMag.com, including every generation of the iPhone and the Samsung Galaxy S. I also wrote a weekly newsletter, Fully Mobilized, where I obsessed about phones and networks.

My Areas of Expertise

  • US and Canadian mobile networks
  • Mobile phones released in the US
  • iPads, Android tablets, and ebook readers
  • Mobile hotspots
  • Big data features such as Fastest Mobile Networks and Best Work-From-Home Cities

The Technology I Use

Being cross-platform is critical for someone in my position. In the US, the mobile world is split pretty cleanly between iOS and Android. So I think it's really important to have Apple, Android and Windows devices all in my daily orbit.

I use a Lenovo ThinkPad Carbon X1 for work and a 2021 Apple MacBook Pro for personal use. My current phone is a Samsung Galaxy S21 Ultra, although I'm probably going to move to an Android foldable. Most of my writing is either in Microsoft OneNote or a free notepad app called Notepad++. Number crunching, which I do often for those big data stories, is via Microsoft Excel, DataGrip for MySQL, and Tableau.

In terms of apps and cloud services, I use both Google Drive and Microsoft OneDrive heavily, although I also have iCloud because of the three Macs and three iPads in our house. I subscribe to way too many streaming services. 

My primary tablet is a 12.9-inch, 2020-model Apple iPad Pro. When I want to read a book, I've got a 2018-model flat-front Amazon Kindle Paperwhite. My home smart speakers run Google Home, and I watch a TCL Roku TV. And Verizon Fios keeps me connected at home.

My first computer was an Atari 800 and my first cell phone was a Qualcomm Thin Phone. I still have very fond feelings about both of them.
