Motorola Xoom WiFi-only has a SIM card slot, why?

If you have picked up your WiFi-Only model of the Motorola Xoom, you have probably found the SIM card slot and have been banging your head against the wall trying to figure out why it’s there.  If you are unfamiliar with the way mobile internet works, a SIM card is needed for GSM carriers (and CDMA for 4G) to activate the device on the network.  However, a WiFi-only model shouldn’t need a SIM card…thus the name WiFi-only.  So why in the world is there a SIM card slot on the WiFi-only model of the Motorola Xoom?!

Motorola has not officially released a statement as to why the extra slot appears there, so consumers took it upon themselves to create theories.  Some say that the WiFi-only model has a 3G/4G feature.  However, that would require a 3G/4G antenna which is not inside of the WiFi-only model.  Therefore, this theory doesn’t make any sense.  Others say that the Xoom will work as a phone (similar to the original Samsung Galaxy Tab) after a software update.  Again, this would require not only a software update but an additional antenna.  All in all, the SIM card slot is completely useless due to the lack of any wireless antennas that would take advantage of a SIM card.

One of my favorite theories comes from Sean Aune from TechnoBuffalo.  Aune has experience in the financial aspects of companies like Motorola.  He states that creating a molding of a product like the Xoom can become very costly, around $100,000.  Removing the SIM card slot on the WiFi-only model would require a new molding, therefore requiring more money.  Instead of spending money to remove a little hole that can be easily ignored (or used as a holder for another SIM card or a memory card), companies many times just use the same mold for different models of a product.

Although this theory by any means hasn’t been confirmed, it is the one that makes the most sense out of all of the theories that I have read.  Do you have a theory on why the SIM card slot is on the WiFi-only model or do you agree with Sean’s?  Let us know in the comments!

    The pricey molding would be a good theory except that if it were the case, there would not be a sim reader in the device. Motorola could easily keep the same body molding and remove the reader on WiFi models to cut cost if there was no real use for it. Now what would make more sense is that the Wifi and he WiFi + VZW versions are actually identical with the exception of the color of the body…the WiFi only version just has the other antenas disabled. This is probably the case since both versions also weigh the same, showing there is probably no physical difference in the hardware. Another point too is that the VZW version is being pushed with the “free 4g upgrade” that requires Motorola to add additional hardware…I think theres a chance that the upgrade might be available for WiFi models, just not for free.

    The SIM card slot is also a MicroSD slot.

  • Springs Guy

    No it is not. the micro sd card is smaller. It does not fit. Looks like the contacts inside are for SIM reading only

  • Yabdouny

    I just bought one with WiFi Only, and when you take of the SIM card reader, just near it there is a micro SD reader.

    My guess is the wifi only model has all the components to make the sim card slot work, its just disabled.
    It is cheaper to make them all the same and disable whats not used.

    Time will tell

    if you notice though most printed circuit boards are missing a couple components depending on the model and version. I see this in motherboards for PCs all the time and since it’s just a small computer i imagine they could have just not included the antenna and made a different version of the software. If you looked at the 3G version you could probably find out what you need to solder on to your Wifi-only to make it 3G. You would still need to flash it and would probably need to replace some already soldered on components.

    Yes Yabdouny you are right  and the sim card is not for micro  sim card   you can put  it right behand the slot cover and slot it back.
