Hi
OK, I have just received my Atrix, and am having trouble. Basically, it will not connect to mobile data.
It is an AT&T model, unlocked to all networks by the seller. I can make & receive phone calls (now I've found how to skip Blur setup), and have entered the correct APN settings, but it refuses to connect.
I am assuming this is a radio/frequency issue. Are there any radio images that can be used to correct this, so I can use this in the UK? On the Defy there is an app called "baseband switcher" which can install the correct info for you.
---------- SOLVED ----------
Just a quick edit to show this issue is fixed.
I am unsure what fixed it. I have performed most of my testing at work, and found that the issue here was a problem with my provider (they were doing maintenance in the area). But it didn't work at home either, initially. I have flashed several radios, modified pppd-ril.options and replaced libmoto-ril.so. Something out of these has fixed my issue.
If I get chance I will remove some of the mods to see if the issue comes back, and post the results here for anyone else who comes accross this problem.
By the way, this has only fixed the issue of no 2G data. 3G data on 900MHz is still unavailable, as far as I am aware. If anyone knows how to check which frequency is currently being used, I can check this further, otherwise I think this is the best we can hope for at the moment.
Hi
Does anyone know the answer to this?
Can I flash a UK/European radio on this (AT&T) Atrix? I have installed Aura, will this make a difference? Are there "fruitcakes" available for the radio, or must I use and SBF?
I have tried to research this through the site (and google) but I can find no definitive answers. All I think I need is a 900/1800/2100 baseband. I definately have the correct APN settings, and mobile data has worked while I've been out and about, but it is very patchy and I am not getting mobile data in places I know have good signal, and am noit getting 3G in places I used to.
I had this same problem on my Defy, and this was easily fixed using the Defy Baseband Switcher app. Selecting a UK baseband fixed all my issues then, so I expect the same now.
Please help
Thanks

Hello
I'm interested at the answer too. I have bought AT&T version from US and imported it to Europe.
The problem for me is that I need Atrix to use 900MHz 3G. I can use 2100MHz 3G but when the 3G is build using 900MHz, Atrix is not able to use 3G, only Edge or GPRS. I have other phone with 900MHz/2100MHz support which I use to verify existence of 3G service.
I have tried with radio version N_01.95.00R which did not work with 900MHz. Just couple of minutes ago I installed N_01.100.00R (CWM zip), haven't yet tested it with 900MHz.
I have seen reports from users owning Atrix, that they have been able to activate 900MHz 3G support by installing N_01.95.00R or N_01.97.00R.
If N_01.100.00R does not work, I''ll try N_01.97.00R and after that I don't know what to try.

Thanks, that's more info than I've managed to glean from my research.
I'm also on a network which uses 900MHz for 3G (in some areas at least) so this may be my problem. I'm currently on baseband N_01.77.15P. If you wouldn't mind letting me know once you've checked I'll wait for you to report back about
N_01.100.00R.
By the way, does anyone know if there are these "fruitcake" things for radios, or do they have to be flashed from SBFs?
Just FYI, I got impatient, and work has been quiet, so I tried myself.
1.100.0R and 1.95.0R made no difference for me.
I also tried an international 1.97.0R SBF, and this gave me an error while flashing... was quite worried till I pulled the battery and it booted back up fine.
I just want to add, here, that if I manage to get 3G reception I can use it fine. However I don't get 3G in very many places, including ones which worked perfectly (full signal) on my Defy. Also, as soon as it tips over to 2G in these places, it shows the "G" icon but does not allow any traffic.
As I said, this is exact problem I had with my Defy when a ROM I installed changed the baseband to a US one from a UK one, and it was fixed as soon as I changed back. So "all" I need is a baseband which will install on my (BL unlocked, SIM unlocked, Rooted and ROMed) AT&T Atrix which is compatible with (O2) UK bands (specifically 900MHz for 2G & 3G and 2100MHZ for 3G only).
I tested with N_01.100.00R, but no success.
I don't know anything about "fruitcake", but I have installed new radio versions either from sbf with RSD Lite or from zip-files using CWM.
Where to find radio versions made for Europe/international use?
I have an AT&T Atrix in Germany, everything works out ok. Try following:
Go to http://forum.xda-developers.com/showthread.php?t=1163009 and flash the radio from there.
In your stock dialer, dial *#*#4636#*#*, choose Phone Information, Set preferred network type to "GSM auto (PRL)" or "GSM Only".
Before all that though, make sure you have the correct APN, it'd be a bummer if it's that simple..

Hi
Thanks. I have checked the APN settings so many times now that I could probably recite them by heart I have also installed an app which sets up the correct settings for me, so I'm pretty sure they are right. From *#*#4636#*#* network type is set to GSM auto, and "GSM disconnects" says "fail because Unknown Data Error".
Which radio from that post, BTW? The AT&T .91 one?

Yep, that's the one I'm using.
Try flashing that and see how it goes. Though data should work regardless older / newer radio; have you tried calling your provider?
Nup
Flashed the linked radio, and it made no difference.
By the way, I finally found where the "Select band" item was, it's in the 4636 menu, phone info, menu key, select band. This shows only USA.
I think I may try flashing the French fruitcake located here just to see if that fixes it. Orange France uses the same frequencies. I know it's stock, but I can try flashing a custom ROM after. I just want to get this thing working now...
Also, there is a post here which seems to suggest a method to fix it, but I am at work and it's too much hassle to set all that up here.
I tried to flash couple of international sbf's but none installed, sec_exception febe 35,35 was the problem.
Then I tried to install Bell radio from bellradiolatest.zip using CMW. Now I have version n_01.77.30s.qn, haven't tried 900MHz yet but 2100MHZ is working as it was with other versions.
4636 menu shows me also the USA Band, which is only option, cannot be changed.
After I have verified that this n_01.77.30s.qn ain't working, I'll try AT&T .91.
I'm using Cyanogenmod and prefer it, I just can't stand the original firmware or something based on original one. For example, week starts from Monday here, in CM I can choose it but US based firmwares week starts from sunday and cannot be changed.
I can confirm that flashing a French fruitcake doesn't work, results in flashing red led. Restored from backup, back to square one.
The Atrix from AT&T does not have the ability to utilise the WCDMA network on the 900Mhz band.

Is this certain? Can anyone confirm this?
Also, does anyone know if O2 UK are disabling 2G on 900MHz when they enable 3G?

It is confirmed by motorola themselves, at the motodev website. This is the link to the said page.
WAN: VOICE BANDS GSM 850/900/1800/1900,
W-CDMA 850/1900/2100

Never heard of a carrier disabling a network they already have, but why would you be worried?
That sucks!
Anyway, the reason I was wonderring is that I cannot get a 2G data connection either. I have been told now on another forum that this is not the case, and I should be getting 2G data. So it seems the phone cannot even make a 2G data connection at 900MHZ (this network only does 2G at 900MHz, 3G is at 900/2100MHz). In *#*#4636#*#* it shows DcAtivatingState for ages, then goes inactive with "Unknown Data Error".
When I can get a 3G signal it is fine.

Could you type the whole thing out? Also, check your apn settings
I am absolutely certain the APN settings are correct, I have checked them over and over, set them using an app, and verified against my previous phone as well.
State: Dc ActivatingState is connecting to [ApnSettingV2] giffgaff data, 1357, 23410, giffgaff.comm , , , , , -1, true, -1, 0, 0, *, IP, IP

It sits at that for a long time, then goes to

fail because Unknown Data Error

I have also just had a reply on my operator's forum from another user who says he had exactly the same problem with this phone.
Now it's just gone into DcActiveState, and says the connection is available. However, nothing gets through. It reckons it's sending and receiving PPP packets, but I can't ping anything, can't nslookup, and obviously can't browse.
Just tried with my old phone, and everything looks the same (when restricted to 2G only), and it operates perfectly. So it is the phone. I checked the APN settings again, before you ask, and they are identical between devices.
I did read something about the stock AT&T firmware blocking other APNs, but that can't be what's happenning here, can it? I mean, it works fine when it can get 3G.
Right, this is getting irritating.
I just flashed a stock 2.3.4 fruit cake to see if that helped. I added my APN settings, and couldn't connect. Set it in WCDMA only and it got a weak HSPA signal, went through Blur setup. Tried again on GSM auto and no joy, even when it hits DcActivatedState nothing gets through.
I am absolutely certain it is not the APN settings. I am sure they would not even allow 3G access if they were wrong, but with a 3G signal it works perfectly. But on GPRS (in several places, miles apart so on different cells) I can get not data connection.
I am in the UK on Virgin, which uses the T-Mobile Network. Recently they have been having issues in my area, meaning I can only intermittently access the t-mobile signal, and even when I can, I cant receive incoming calls (Although I can make them).
Theoretically its not a problem as I can roam onto the Orange network by manually selecting the network. However, it seems that as soon as the t-mobile network is available, the phone automatically reverts to it and my problems start all over again.
Is there any way I can force it to stay connected to Orange? Or can I set Orange as the preferred network?
I am running the ressurection remix 4.0.4 rom.
Thanks in advance for any help,
Pebrey
It's not much help to you I know, but I had the reverse issue (on Orange, wanted to use T-Mobile) and according to all the searching I did and a call to Orange, it cant be done; it needs a change to the SIM card. I ended up changing network instead!
Orange and T-Mobile have merged together to form Everything Everywhere, so if your being put on orange or T-Mobile that's just your phone selecting the network with the best coverage

Cannot get my sim to stay on tmobile, keeps changing to tmobile orange, which is useless if u want to use your mobile internet. Would like a way for it to stick to tmobile!?
I picked up an unlocked TMo One in New York last week. I used it there with my Norwegian SIM with no problems.
Back home, I get "No Service" using the exact same SIM-card. Using the *#*#INFO#*#*-menu, I can see the SIM-card is recognised because it displays my carrier in the "Current Network" field. I am suspecting the TMo-infused Sense OS to reject my card, since to my understanding the phone is compatible with EU networks. Will i be fine if i flash another ROM, like the stock GPe, and get rid of the TMo-stuff altogheter, or is there another rock in the road here?
I used my Tmobile HTC One with the stock ROM in Norway using a Telenor SIM and in Greece using a Vodafone SIM.
I would make sure you have the proper APN info (I can't remember the appropriate one for the Norwegian carriers). I believe it should work without issues (mine did). If it worked with that SIM card already, it's not locked and it's not rejecting it.
Also, I found that when I returned home to the US, I had to choose Settings -> Mobile Data -> Network Operators and choose Select Automatically (even though it was already chosen). Maybe you need to do that too.
Currently I am running Android Revolution and that also works fine with my Norwegian and TMOUS SIM cards.
Good luck!
Thanks! I've at least made some progress. I tried setting Network Selection to automatic, and got reception, however only for about half a minute. I then tried adding my provider's APN info. This has given me permanent data connection, but still no GSM reception for texts and phone calls. I do get 2g data when in low coverage areas. I am finding this weird. Can anyone shed some light?
Okay. Just wanted to post my latest findings - if others are experiencing the same issue. I've flashed the latest Google Edition RUU, to see if the TMo ROM was causing it. But i still don't get GSM coverage. Data still connected on both 2G and 3G (haven't been within 4G coverage yet..)
When flashing I also updated firmware to latest.
Phone info says Current network: "NetCom" (my home network) GSM service: "Emergency Calls only" (I tested this, and I am able to place the call to emergency services) and GPRS service: "Connected" (I am typing this on my data connection via WiFi-tethering, actually)
The status menu shows this: Service state "Out of service" and My phone number "Unknown".
If anyone can come up with a theory, I am all ears..

Have you tried taking the phone to your provider? Maybe you need an update which or setting which they can provide.
I find it strange that it wouldn't recognize your phone number, usually that's a sign of some type of incompatibility with the phone and the network.

I have contacted my provider to see if there's anything they can do. But they're playing a little hard to get.. I was afraid there would be an issue with compatibility at first, by since my data connection is all right, I'm not so sure. Also erdelyt above here says he has used the TMo phone in Norway without trouble. He has another provider, however. They run their own network, so I will be trying with one of their SIM cards next, if my provider NetCom aren't of any help. Thanks for your help so far. I'll be posting my findings further!
So, I got to try a Telenor SIM card the other day, and the issue is still there. Although, with that card the phone number was read and displayed in the phone info menu. The owner of the card suggested there was an unlock issue - but I did make calls with my phone and SIM card in the US, so I don't see how that could be.
So that's a small step further, but now I just have to wait to see what my carrier says..
I changed the title for this thread after my findings.. I got a new SIM-card for my carrier, and i got coverage to make one phone call, but after i hung up, it was gone. I am really in the dark here.. It can of course be a hardware fault, but that's a bit strange for an entirely new product..
Hi all, I landed in Heathrow for vacation a couple days ago and immediately bought a local sim (EE 500 mins, unl text, and 2gb data). I swapped it out while on the tube and I got and unknown sim icon in the status bar. Weirdly, it appears I can send and receive texts (I was getting messages from EE) but I cannot use data. Furthermore, when I took the Eurostar to Paris yesterday, I got a text from EE welcoming me to France, informing me of roaming charges etc so it is clearly communicating with their servers.
I'll be heading back to London on Tuesday, and I'd like to have data then.
I am rooted, but still running stock ROM.
Is this a Verizon, LG, EE problem? Or is it a combination?
Any help would be greatly appreciated
Thanks!
Probably some APN issue but I wouldn't know what exactly you need to do to fix it. Anytime you run a phone that's set up for one carrier on a different one you usually have to at the minimum change APN settings to have full functionality.
Maybe where you got the SIM from can give you the correct APN settings. Make sure and back up your existing APNs first.
Enjoy your vacation. Safe travels!

Thanks for the reply! I created the appropriate APN with info from their website but still no dice :/
Ur going to have issue the icon will remain as long as u are you using a non verizon sim as far as data normal issue have been not being able to recieve mms. Make sure data is enabled then recheck your apn make sure its fpr smartphones then if all else fails it possible your carrier may not be able to connect to data via verizon hardware
I am getting the same problem in the UK - see the OP - same 'unknown SIM' icon in the top bar. I have voice & text, but no data.
Two different carriers in the UK give me the same problem - 02 and EE - so it's not unique to one carrier. If anyone has further info I'd appreciate it - otherwise I'm down to put this phone aside & buy a new one as I'm living the the UK for a year or longer.
Has anyone been able to attach a Verizon LG G3 to a UK providers data? If so, how? LMK please!
Thx in advance!
