Since the euro 3G version has launch, most of the US here either use a WIFI or the CDMA with the missing PCIE HSDPA card...
Now, I'm wondering what card are they using? Will it work if we manage to get the card install and flash the 3G firmware to it..will it enable the function??
Any insight?
Thanks!
I would bet that the UMTS model doesn't have a card; why would it? It would permit UMTS models to get the LTE upgrade in future as well.
Regardless, there's teardown threads elsewhere showing that trying to graft 3G onto a Wi-Fi model is going to be prohibitively difficult with respect to hardware.

I just bought a Xoom with 3g (Verizon). I live in Canada and don't really need the 3g here at home (Wifi at home and work). However, if I travel to China or somewhere else, is is possible to unlock it so I can use the 3g network there?
Does root the dervice help? Please enlighten me ot point to to the right direction. By the way, I don't really care about the lte upgrade, so I don't worry about voiding the warranty.
Thanks in advance.
It depends I think. From a very quick search it looks like China may have one or more CDMA networks available. That said, it depends which band they use and probably what are you are going to... I believe that like Canada, China is rather large.
If you're talking about world travel in general, you would have been better getting a European GSM version as most of the networks in the world use GSM rather than CDMA.

Actually the US Xoom 3G has a Qualcomm MDM6600 chip and if you do a search on Google then you will find that it's actually a "world mode" baseband capable of supporting both CDMA/EVDO and GSM/UMTS networks. Xoom also has a sim card slot, so i'm wondering if the European version will come with the same hardware and they will just enable the GSM/UMTS part...

Still doesn't take away from my point that the chip, whether it be GSM capable or not, isn't enabled for it.

Yes, you are correct and i didn't say you aren't.
I'm just very interested in seeing if the hardware will be different or not.
Hello all.
i've a US 3g motorola xoom. it will be upgraded to have 4g. but how about 3g? how about sim card slot?
see here please : http://www.droid-life.com/wp-content/uploads/2011/02/xoom-4g-upgrade1.png
"When motorola xoom launches on 2/24, it will be a 3G ready Device"
as i know 3g will be work after upgrade, as in the sim card slot i see that : "replace with sim only after 4g upgrade"
3g on my device not works. when i put sim card nothing happens.
so my question is, does my xoom have 3g hardware or not? it's not working because it has not the 3g hardware or it's just because of software?
for 3g to be work, i have to send my xoom to motorola for upgrade or i can buy it's hardware and done it myself?
i'm asking this because i'm outside of US. i dont know if i can send my us motorola xoom for upgrade or not. will they return my xoom to outside us? i'm in turkey.
see here please : https://supportforums.motorola.com/message/434179#434179
You might want to post this in the Q/A section and not the development section.
Not sure what exactly you mean, but the Verizon/3G version of the xoom works 3G out of the box. You do not need to install a sim card to get 3G. When you buy the 3G version, you need to setup an account with Verizon, setup a data plan, and then activate your device on verizon's network. A SIM card was not needed when I used 3G on my Verizon Motorola Xoom.
You can't take any sim card and install it to the xoom, yet, I believe (correct me if i'm wrong) when verizon is ready to start the 4G setup, you need to send your xoom in because they have to add the 4G device into your xoom, possibly opening it and adding it OR replacing your current one and giving you one that already has one installed. Or maybe the SIM card they're going to install is the 4G device itself, possibly.
Edit: looks like they might need to open it up and install a mini-PCI device.

oh, sorry, i post thread in development section by mistake
thanks for your replies.
so, i cannot use the sim card slot even after upgrade for 2g networks? never i cannot use it for example text message just like ipad2 3g?
how about the 3g uk xooms ? can they use 2g simcards?
does those have sim card slot or they work without sim card in 3g like mine?
isnt there anyway to get 2g/3g simcard worked on my 3g verizon xoom? even with upgrading/replacing hardware myself?
is there any mini-PCI chip that enables xoom to operate sim card? for example massaging or using gprs (2g) network. just like ipad 2 3g
as i see on other topics, probably airprime mc7750 will be installed on our devices during upgrade
and i see on it's website that it supports gsm/gprs.
so do you think can we use 2g/3g sim cards after upgrade?
can uk 3g xooms operate simcard for 2g/3g networks? if yes, whats difference between their xoom's hardware with mine? can i replace hardware? for example install a mini-pci-e 3g/2g modem
hello all,
i've a 3g verizon us xoom. may i install uk 3g xoom's rom on it?
may i use a 2g/3g sim card after that?
thanks
Same Problem
Hi developers,
I have a very similar problem, except for I'm trying to use my US (used to be Verizon - but I UNLOCKED it) with China Unicom's 3G sim card. It won't pick up signal. I wonder if that is possible and what I need to change in order for it to work.
Any help will be appreciated,
thanks
The US xoom is cdma 3g and not gsm, which is why it wont pick up signal. Also the simcard slot is not for the 3g but for 4g which isn't available yet. I would doubt it would work.

Verizons xoom is CDMA and the hardware is different, the sim slot in the verizon has no hardware yet. When the free hardware update comes in at some point it will be 4G not 3G.
So in short the answer is NO.
Lordao
YES! you can use any images on your verizon 3G XOOM!
I have tried several, and they ALL work!
you WILL get your SIM working as well!! but you will not be able to use the 3G GSM network, because the images do not contain the baseband files used for the radio.
Hardware differences have not been confirmed by anyone, people are just assuming. The radio chip used multi-frequency capable hence must be the same.
One must do a baseband firmware change, to find out if the CDMA to HSPA/GSM will work!

Ok
Thanks for your responses...
I'll go back to China Unicom and ask them for the CDMA 3G, since they're supposed to have that, too.
hello all
i have a 3g verizon xoom but im outside us.
here we have only gprs and and edge in 2g networks. no 3g yet (hehe but we have 2 wimax operators)
so i cannot use my sim card in my tablet, as i know it does not have the required hardware.
as i understand from forum posts, in 4g upgrade they will install a new mini-pci-e hardware and reinstall a new version of android.
may i buy that mini-pci-e card myself and install it? then can i use my 2g sim card on tablet for gprs or edge?
im in iran and cannot send xoom to motorola.
is there anyway to use sim card in tablet? with/without hardware upgrade
The GS3 Verizon is a CDMA device. Supposedly it has GSM compatible radios too. It's supposed to be able to work on GSM networks after a software update coming soon. Does this thing have a sim card slot? I don't see how it would work on GSM networks without it. Does anyone know how this works?
I'm hoping to use it on Verizon in USA, but on Telcel while in Mexico BUT with my Telcel sim. I realize my hopes are slim but if there's a sim card slot maybe it's possible???
Thanks.

It has a SIM card slot for the LTE. Unsure about compatibility though.

Actually, I have an old Verizon Motorola Z6c World Phone here that I bought in 2008. It has a Verizon sim card inside.
Z6c Specs say:
2G Network GSM 900 / 1800
3G Network CDMA 1xEVDO (800 / 1900 MHz)
Anyway, there's no LTE involved on the Z6c back then. SO apparently the GS3 will need the sim on non CDMA networks. I just wonder if the software experts here can make it possible to use the sim only at certain times and at the same time unlock the phone.
A lot to ask but will be a huge feature if done.

I said earlier that I wasn't sure about compatibility, but I'm starting to believe that this is not possible, as the Verizon version lacks the proper GSM/HSPA+ radios. There's a model comparison chart that you can expand on the Wikipedia page. Software probably won't be able to pull the miracle you're asking for. Sorry

Maybe this will help? http://androidcommunity.com/verizon-may-enable-global-roaming-on-lte-phones-soon-20120518/ from what I gather LTE is based off of GSM and its just a matter of unlocking the GSM bands on the phones.

The SCH-i535 did recieve GSM certification for bands 850 and 1900. No HSPA+ though.

Yeah, I don't think the current specs out on the GS3 are totally complete. If the phone is admittedly needing a software update to allow the GSM roaming then they can't just put those bands in the specs with no caveats.
