[Q] how to tell if my XOOM is 3g or 4G - Xoom Q&A, Help & Troubleshooting

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

Question about xoom's hardware

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

[Q] may i install 3g uk xoom's rom to my verizon us 3g xoom to get simcard working?

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!
Check out this thread:

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.

[Q] 4g upgrade

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

Is there any way to flash 3g mz600 to 4g lte?

I just picked up an mz600 that's stuck in 3g land. Very proficient with adb and SDK and am used to being able to flash radios and what not with my cell phones.
On my xoom is there any way after I rooted and unlocked to be able to just fast boot the lte radio or flash the radio so I can sim card this thing and get lte?
I have searched and searched and haven't came across a real answer.
OK just found out my answer.
New question, does anyone know if a 4glte card from a mz602 is compatible with an mz600? I have found that I need the card first. Then install the lte card, then flash lte software, then I should be able to install a sim and have 4g.
OK. Here I am. I found out all my information. I have ordered the card and should have my 3g xoom on lte this weekend
We'll here is the update. I am pretty sure it would have been much easier than what I did but...
I have converted my 3g xoom to 4g lte
If you buy the lte modem and install it. Then unlock and flash rogue recovery and just flash the lte radios you will be able to use it.
The couldn't activate on their end because they kept asking for the meid because it was a 3g xoom on their network previously. I told them I did the conversion myself and when I got to tech support I found a fantastic tech. She was patient, got her manager involved. In the end we discovered she needed my imei number and not my meid.
Very happy.
But note you must use the imei after you upgrade. Or the sim will not attach.

[Q] [Verizon] Tablet LTE Data SIM in Android phone with 3G?

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!
bump
