Installing A SIM Into A Sierra Wireless GX400W Or GX440W With WiFi

Many of our clients who order Sierra Wireless AirLink GX400 or GX440 cellular gateways with WiFi (like these models 1101531,  1101691 ) find out the hard way that the SIM is very difficult to install. The SIM does not come pre-installed, and the process is not quick to perform. Do it incorrectly or incompetently and risk doing damage to the device itself.  I highly recommend opting to have the SIM installed at the time of sale. Companies like USAT Corp. do that service for a very nominal fee and it comes as a standard part of the device provisioning (DevProv+) professional services. However, if you find yourself in the situation of having to install the SIM yourself, know this key information:

The SIM slot is located on the front left (as you are looking at the side with the lights and the reset button) behind the plastic cover. To access the SIM slot on the device you must remove the plastic cover with a 2mm or 5/64” hexagon Allen wrench.

Step 1: Unplug your GX400/440 from power source.

Step 2: Remove the four hex screws on top of the unit (used to secure the black cover) using a 2mm or 5/64” size Allen (hex) wrench. Place screws in a safe spot, these screws will be used again.

Step 3: Remove the nut and washer from the front facing SMA connector using a 5/16 or 8mm socket torque wrench to a torque spec of 8in-lbs. Place nut and washer in a safe spot, these will be used again.

Step 4: Slide the top black cover off of the device.

Step 5: Install the SIM card with the gold contacts facing down and the cut-out facing to the right.

Re-Installing The Cover Plate

The cover has a tab to mechanically secure the SIM in place during extreme vibration. When replacing the cover:

Step 1: Install the black cover by lining up the SMA antenna connector with the hole in the cover, tilt the rear of the cover slightly to make sure the front bottom of the cover seats in the front ridge, and then push the top of the cover down.

Step 2: Re-install the 4 hex screws on top of the unit.

Step 3: Place the lock washer onto the SMA antenna connector and push to the face of the cover.

Step 4: Install then tighten nut with a 5/16 or 8mm socket torque wrench to a torque spec of 8in-lbs.

Transmitting GPS Data Using Sierra Wireless's GX400/GX440 With WIFI

Recently, a client had a question about whether GPS data could be transmitted to a laptop wirelessly using the wireless LAN access point built into the the GX400 or GX440. The answer is “yes, you do not need to use the an Ethernet cable to pass this data.” More info on how to set this up can be seen at USAT’s Common Questions page. 

Please remember that NOT ALL of the Sierra Wireless AirLink GX400 and GX440 line contain WiFi access point functionality. This feature is limited to the following Sierra Wireless GX400/GX440 part numbers:

  • 1101524
  •  1101525
  • 1101522
  • 1101523
  • 1101529
  • 1101528
  • 1101530
  • 1101531
  • 1101690
  • 1101691

The MP597W and the MP890 can be set up in much the same way.


Verizon Wireless LTE Sim Supply Chain Improvements At USAT

In service to our clients who are migrating to VZW LTE modems and network devices, our company, USAT Corp.,  is often tapped to perform device provisioning as part of our M2M deployment services package (DevProv+). There have been some bumps in the road on the migration to LTE, as our work flow involves tapping an appropriate Verizon Wireless sales professional to provide USAT with activated sims prior to device programming taking place. This has caused some delays, as it sometimes has taken weeks for LTE sims to arrive at USAT. The good news is that and Verizon Wireless and USAT have worked to rectify this supply chain issue, and USAT will have sims in hand in early June. This will allow for faster turnarond times on deployment services for the GX440 (1101414) and the CradlePoint IBR600LE. With the Verizon Wireless LTE sims in hand, USAT’s deployment services will once again return to our typical quick turnaround times for provisioning services.

Sierra Wireless AirLink GX400–An Insider's Guide

At CTIA in April, Sierra Wireless announced their new intelligent gateway platform, formally code-named Sharks, now officially named the Sierra Wireless Airlink GX400. I must editorialize here, and mention that I am disappointed that Sierra Wireless has made a departure from the former AirLink naming convention, which was word-based, and moved into the generic alpha-numeric format. A quick search of  the product name GX400 on Google turns up a Dell computer and a Honda car. Thus, the term GX400 is going to be difficult to brand as a Sierra Wireless intelligent cellular gateway. I vote that they immediately change the name to the Eagle. The ALEOS operating system on the GX400 soars, so Eagle would have been apt.

The feature set of the GX400 is an interesting amalgam of features from the Sierra Wireless Raven X and the Pinpoint X. This device has both the serial and the Ethernet ports of these devices, as well as the built-in GPS receiver of the PinPoint X. For clients who are streamlining their IT standards list for wireless telecommunications, and would like a single platform that can handle M2M and Automatic Vehicle Location (AVL) applications,  than this is the one. In addition, it is significantly less expensive than the Pinpoint X and much less expensive than the MP–both entries in the AVL space that Sierra Wireless has been very successful with. So why won’t every end-user jump ship from the PinPoint and the MP to the GX400 then? Well, the GX400 does not, at least at this time, have an option to integrate an WIFI access point inside the device, as the MP series does. And the GX400 also does not currently have any i/o telematics ports to offer, so setting up triggers with the GX400 is not possible at this time. As you may have noticed, I am being careful to use time qualifiers when discussing the feature set of the GX400 and comparing the feature set of the GX400 with the Pinpoint and the MP. This caution is due to the fact that the GX400 does have an expansion slot. It is my strong belief that Sierra Wireless will soon be announcing the availability of a wireless LAN module for the GX400, and with WIFI in the expansion slot, this functionality would make the device more on-par with the MP. However, please not, this expansion module has NOT been released yet. See more about the Sierra Wireless GX400 specifications at

Currently, the VZW GX400 is the first to market, and this device is shipping at this time. Sprint will be next to market, and the AT&T device will be last to market (I hear that it is still being certified on the AT&T network at this time).

As in interesting marketing ploy, (which is also useful for clients that are very interested in rapid adoption of the GX400 platform), Sierra Wireless has announced that clients that buy  a special “upgrade-ready” version of the 3G GX400 today can upgrade to the 4G GX400 anytime prior to 12/31 2011. The upgrade program is not entirely a giant cash-saver and is not entirely high on the convenience meter, as the upgrade requires a $290 investment to perform this upgrade AND a trip back to Sierra Wireless to perform the upgrade. However, it still offers a viable upgrade path that will, ultimately appeal to a select set of enterprise users who need to deploy today, but want future flexibility. And, Sierra Wireless in the interim is able to announce that they have made the first LTE intelligent gateway available to the marketplace. For a complete description of the GX400 3G to LTE Upgrade Program program, you can navigate to

In closing, for those Raven X, XT, XE users who are still jittery about rapid obsolescence about their device of choice, (since Sierra Wireless for a short period of time announced the upcoming end-of-life of the Raven in 2010), fear not. The Raven is still on the roadmap for 2011 and 2012 as well.
