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.

Telus Milestone problem with 3G

Hi,
I just bought a Telus Milestone while in Canada las week, I bought it from a Best Buy store in Toronto.
I live in Costa Rica and we use 850mhz 3G band but for some reason is not picking up 3G band only GSM with EDGE data connection.
I already try the "WCDMA only" option but still not working it goes out of service.
Is there anything different in Telus 3G network that could be not compatible here?. All of the iPhones 3G and 3GS work here with no problems, same as some other ATT phones.
According to the FCC my phone supports 850mhz 3G band.
Behind the battery it says: FCC IHDP56KC5
And according to FCC documentation it supports WCDMA 850/1900/2100 plus HSDPA 10.2 mbps
So, I don't know what's going on...
Hope somebody can help me, I heard there is a Field Test hidden option on the phone that can show some troubleshooting information, but I don't know how to access it.
Thanks for the help,
Luis
Planning to buy one too, so it'd be handy to know what's going on there. I take it you bought it unlocked? Also, is the APN and all that setup correctly? How do you have it setup, is it one of the new 3G phone lines or an old GSM one (which are capable of 3G as well)?
I have the exact same problem down in Mexico, I just received an unlocked Telus Milestone and all I get is edge. I am using the same APN configuration that I have on my Rogers Dream (G1) and I do get 3G on that one.
Also, I believe this forums are for HTC phones only, I'm not sure we'll get lots of help here on a Moto issue.
Mine does work on HSPA+ here on Telus.
Just a hypothesis would be: Since it has only been released on HSDPA/HSPA+ network in Canada, they haven't done proper testing on 3G mode and there is a bug in 3G only mode.
Like I said, I can't say for sure since the only other GSM network we have here is rogers which is mixed 3G and HSPA+.
On second thought, I do have a Fido/Rogers SIM lying around so I'll give it a shot over the weekend and let you guys know.
Thanks Ady, it does sound like a compatibility issue. I have tried Telcel, I should be able to try ATT in the US next week.
Other than the 3G issue, this phone very darn nice... way faster than the dream, Multitouch work's great ont the browser.
yeah, its really good.
Update: I gave fido a try and it seems to be working, but on HSPA.
I bought it locked to Telus, and got the unlock code from "UnlockMotoDroid"
My SIM card is one of the old GSM ones, but I already try the new 3G SIM Cards (kolby3g) and same problem, only EDGE data connection. APN and all that is correct.
pasker17, I'll love to hear if you find a solution. Keep me posted.
Ady, agree with you, other than the 3G issue, this phone is pretty awesome..!!! Hope I can find a fix soon. I'm wondering if this could be related to the HSPA+ advanced technology that might not be compatible here, but as far as I know it should be backwards compatible with any other 3G technology.
And also, I heard people is using it with AT&T no problems, 3G data speed. Do they have HSPA+ ?
Thanks for your help guys
AllI can tell you guys is ther eis something diffrent with Radio signal we are using here ( Canada ) and the one in South America, I been tryin to use Latam f/w on my stone and no signal aty all whatsoever , so th eother way around doesnt work , they must be something we are missing about network compatibility , 1 thing I am sure Telus 's 3g network is the new HSPA .
double post sry .
DAG,
Yes, maybe there is some sort of advanced HSPA+ network in Canada, and that might be the reason is not working in some other places.
But as far as I know, all those HSPA+ flavors, should be backwards compatible.
Now I wish Motorola frees the bootloeader and I can try it with some other custom ROM.

That wouldn't be it. If you the iPhone works in Costa Rica the Milestone should work.
Have you called ICE? From the very brief info I can find on how to get the iPhone to work in Costa Rica it almost appears that ICE itself has to approved the devices on its network. Apparently they have approved the iPhone. I assume they'd do it via IMEI

Yes and no, you do need to provide an IMEI to get your data plan working, but it should work with any device. I did it when I had a 3GS and have used my SIM on other phones and 3G works normally when setting my old apn. This is indeed bizarre
I called ICE, and went to their offices. Milestone is not
in the "approved list" so they won't even take a look. Same with the iPhones they work fine but are not "approved".
They already got my Milestone's IMEI registered on the system.
At the end they told me that this could be a software incompatibility but since the phone is not "in the approve list" there is nothing else to do or test for them.
Since this phone for sure supports 850mhz 3g band, I'm starting to think that it could be a software thing.
I'll be in the US in a couple of week and will try to test it on ATT, I heard a lot of people are using Canadian Milestone there with full 3G speeds

I take it you've tested known-working SIM cards and all (not only Kolbi ones), I know for a fact that mine works with APN: icecelular, if you care to give it a try with mine, let me know and we can arrange something. I really want to buy a Milestone and want to know if it works with 3g here or not
I've tested GSM Sim Cards (green and pink) and kolbi3g SIM cards, all of them with data enabled, not of them works with 3G data speed only EDGE.

OK then, if you've tested with apn:icecelular for the old GSM ones, and kolbi3g for the new ones, then I guess it's something specific to the phone, but this is extremely strange. :S
Great... is working now in full 3G speed.
I just applied the Barazilian update to 2.0.1 and my radio baseband was changed. And now I can get full 3g data speeds and I have an "H" symbol on top

Take a look at this thread

[Q] Motorola Xoom on UAE Etisalat

Hi all! I leaving In UAE - Fujairah, and I'm planing to buy a Motorola Xoom. Maybe someone with more experience than me, can advice me, if it worth, if it will work on Etisalat 3G network, and finally if those Xoom 3G released by Verizon and sell via E-bay are OK for my location. Thanks in advance !!!

Axiom in UAE is going to be selling the XOOM. Sure they can provide more information they have a direct tie up with Moto,
Cheers.
thanks dude, but as far as I know they will bring only WIFI....
The Verizon Xoom uses CDMA for 3G networks. If I remember correctly, Etisalat is GSM only, so it would not work. I'm not sure about 4G LTE though, but that's not active on the Motorola Xoom yet anyway.
BTW, I was in Fujairah a few weeks ago; my Verizon Xoom worked great on wifi.

ok, but in order to use the WI-FI, I need to be stuck in home or any other place which has a Wireless Network.....anyway, it looks like I have to wait for a while....
Maybe I become insistent, but I don't want to spend almost 1000$ for nothing. Can someone to confirm if this model Motorola XOOM MZ601 will work in my 3G network. I already read the details and also I check the compatibility list on above link, but.....i just want to make sure, maybe someone has the similar model and using in GSM network. Thanks in advance!
Does your network use sim card? If yes, then the Verizon Xoom won't work for you.
Verizon 3G Xoom uses CDMA, it won't work on GSM networks that use sim cards.

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.
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

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.

Verizon M8 only connecting to 2G/GSM networks. No 3G/4G.

Hi All,
The issue with my Verizon M8 [the rare LRA (LTE for Rural America) subvariant] is that no matter what firmware version/RUU I use, I only get GSM connectivity on it. No WCDMA or LTE. I have checked the WCDMA bands in my country and that is not an issue. When I select WCDMA only option, I cannot get any signal. I have flashed the all the LRA (*.**.512.*) RUUs as well as all the Verizon (*.**.605.*) RUUs but no luck at all. If this issue might be related to PRL settings then please let me know if any of you have any idea. I have also checked the relevant WCDMA/LTE bands via CDMA tool and they are also enabled.
My M8 is currently S-off and has Super CID. I am using it outside the US on GSM network.
This has got me very frustrating and I need to find out if this is a software issue or a hardware issue. One more thing is that another guy here has exactly the same variant as mine. He bricked his radio by flashing the GSM firmware. I provided him my phone's relevant partition dumps and after flashing those onto his phone, his phone's radio became operational but now he has the same issue as mine. So I think that this issue might not be hardware related.
Any help on this will be greatly appreciated!!

Hello. Yes, I know the bands used by 2G, 3G and 4G in my country. And yes I have switched sim cards even from different networks. The PRL version shows as 00000 when i look at it from the settings. I have even tried to update the PRL from a prl file provided by a xda user in some other thread but still it shows as 00000. I have seen some threads and ppl had this problem with One S. Though some of them were able to correct it by flashing some stock and custom radios.

Well, I thought too that it might be sim locked but then why it is working with 2G networks. There should be no signal at all then. Also these LRA variants are being sold by many online retailers including Amazon as sim unlocked phones. And yes it acknowledges when I insert or change a sim. Says "Preparing sim card" and then I get a signal (2G only). When I choose 3G only in network settings, the signal is gone immediately and I have to switch back to auto or 2G only to get the signal back.

This is strange, as the 3G band 2100 Mhz is really common (many countries use it for 3G, and most any recent US phone intended for foreign travel will support it), and should be supported by the device out-of-the-box. This tells me the problem is likely not RUU/firmware related.
You sure the APN is properly typed? And does your carrier use any different APN for 3G, LTE, etc.?

No it uses the same APN for all types and its configured correctly. I also thought the issue might rather be related to some NV values or PRL. If I set it to 3G only, it "Sees" the carrier as I can see a signal bar in network signal guru app, but the mobile is not able to connect to it.
so i am thinking that since this is a lra variant, a lot of bands may be disabled. have you seen anywhere else that someone got a lra variant to work outside the us? i know you said people were selling it as being unlocked, but maybe its not

Well the LRA variant is practically the Verizon one with everything same as the Verizon variant. There a lot of links on both Amazon and eBay in which its mentioned that its LRA variant and is factory unlocked and can be used anywhere in the world. And yes I came across various threads on XDA in which people had this same variant, working fine (3G atleast) but they wanted to upgrade to Android 6 MM as there is no official update available for this variant after Android 5 Lollipop. As for the relevant bands (2100MHz for 3G used in my country), they were already unlocked (checked via CDMA Tool and QXDM).

it being sim/network locked makes sense, because the phone was made for people who live in the middle of nowhere. there would also be a high probability that none of those people will ever travel outside the country. i do not know anything about the nv values and tweaking them, but i have looked at that thread a few times. lastly, if you have only picked up 2g regardless of sim or apn used, it could be defective radios
