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

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.

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.

Thread moved rather than deleted because question was partially answered. In the future, post all questions in the dedicated Q&A forum.
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.
Sent from my MZ604 using XDA Premium App
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 verizon 3g xoom. it's not upgraded yet. i live outside us
about the UK 3g xoom, can it operate 2g sim card? for sms, gprs or ...
how about normal 3g sim cards?
is there any hardware difference between mine and uk one?
may i operate my 2g sim card on my xoom? how about 3g?
when i put sim card nothing happen. i just tried 2g sim card
our 3g operator is not started selling sim cards ... but we have 4g operator.
if i install uk xoom's rom on my own, can i use sim card?
is there any mini pci-e card that i can use my sim card with it? (self upgrade xoom with custom mini-pci-e)
please help me. i need some information. i'm confused.
http://forum.xda-developers.com/showthread.php?t=1263634
how about this thread? i've done that but dont work for me. there is no signal, i think it didnt recognized my sim card.
if i install the mini-pci-e card that motorola installs on xoom during upgrade, can i use sim card for 2g/3g ? (sms or internet)
i have found this : "If you bought your Xoom from Verizon, it will have no SIM card slot. Verizon's CDMA network doesn't use SIM cards. Also, if you bought the Verizom model, it will only work on Verizon, and not another carrier. There is also a WiFi-Only Xoom, and it does not have a SIM slot."
here : "http://www.ifixit.com/Answers/View/53440/Why+I+can%27t+find+3G+SIM+Slot+in+my+Motorola+Xoom"
but mine have sim slot with a plastic sim on it.
The Verizon 3G Xoom does have a sim card slot but no hardware inside to read the sim card. That is what the 4G upgrade was for, to install the hardware necessary to utilize the sim card for the Verizon 4G LTE network.
I don't know if anyone has gotten a Verizon Xoom working on any other carriers network.
Theres pix of the inside of my Uk3g Zoom somewhere...
how can i tell if my xoom is 4g or 3g i got it from craigs list and it don't have a verizon logo or any other cell phone company, it has the place for the sim card.
i want to root it but Im not sure what rom to install after work because some roms say that is for the 3g only.
any ideas it doesn't say anywere on the housing.
thanks.
If you are in the US and have a US Xoom without a Verizon logo, chances are it is a Wifi only. They all have that rubbery cover for the micro sdcard and a possible sim card, but the WiFi only version doesn't have the necessary hardware/connections to have a sim working.
So root and mod to your heart's content, and if you want connectivity get a personal hotspot.
On a side note, if it was 3g, it would be 3.2.1... 4g would be 3.2.2
Hypothetically speaking, if you were to take a 4G LTE SIM card out of a Verizon tablet that has a dedicated tablet data plan and place that card in a Verizon smartphone, would said smartphone be limited to only 4G LTE data, or would it also have access to 3G/2G/1x as well?
Please no guesses or assumptions- just need to know if the data received on the device is based on the sim card or on internal radios for Verizon.
Thanks!
