After unlocking the phone everything works just fine, including all the Google services (hooray!), but it gets only 2G speeds on T-Mobile LTE network in the USA (4G setting in the phone is enabled).
The APN is T-Mobile US LTE. However, if I go to Settings > Mobile Data > click cog on top right > Data plan settings it shows the phone carrier still as China Mobile in Beijing.
Does this mean that the SIM is locked to China Mobile only? If yes, why is the phone working, although at 2G speeds only?
Is there a way to make sure the phone is SIM locked? I’d like to avoid spending $30+ for an unlock code to find out it’s still not working.
If you have the correct APN settings I think it's the basebands using different frequencies that are not compatible with the p10 lite.

I bought an Atrix in the USA but I'm living in the Netherlands. I was able to unlock my phone with an unlock code from AT&T, however the internet is not working. Calls can be made and H+ shows in the upper right corner but no connection.
After some research (*#*#4636#*#*), I saw that the band was USA and no other selection option were possible.
My question: can the band be changed to EURO in order to make the phone usable?
Have you entered your porvider apn?
I bought mine in the US too and i created a new APN with my provider settings and it works fine.
Yes, I have entered the APN settings and verified them with Vodafone. Problem seems to really be located in the bands used.

vodafone netherlands runs on 900 band and the atrix supports this automatically, you cannot change the band. if the phone is seeing the H+ then it already recognize your network you just have to make sure you use the right apn and have data enabled in your settings. also make sure there is a green circle next to your apn name, this enables the apn.
You may have not activated CDMA in * # * # 4636 # * # * (Phoneinfo) you need to make GSM Auto (PRL)
(CDMA is only U.S. Baseband) in Europe we have WCDMA
wcdma is 3g in north america. ive been using wcdma only setting to stop my phone from going to edge
Settings -> Wireless & networks -> Mobile networks
Change the "Select network" to automatic if it's not already.
download apn internet on off =)...its work for me ....

CDMA is not in the atrix. we use WCDMA just like europe.

AT&T uses WCDMA as well.
We don't use CDMA, that's Verizon.
EDIT: dLo beat me to it.
Still no luck...
1. WCDMA selected as preferred network type.
2. APN triple checked and activated.
3. H+ showing in upper-right corner.
4. Enabled roaming in the data manager to make sure this wasn't blocking anything.
5. Tried SIM in HTC Wildfire with same APN and network settings => WORKING
Any more ideas on what is blocking my internet?? :S
It seems that putting the Atrix on WCDMA preferred is not working, it will automatically switch back to GSM....
I still believe the fault is located in the inability to set the bands to EURO or even automatically. You can only select USA here... If there is anyone who knows how to change this, maybe give a direct command to the modem, I will express my gratitude using paypal
Did you activate the phone in the US? like did you put in AT&T SIM and turn it on? I had the same problem with my phone when I activated it in us, i'm waiting on a new one that has not been activated in US.
I unlocked the phone in the Netherlands with a Vodafone SIM. Tried using a SIM from a different provider just now: T-Mobile = working!
Now I have to figure out what the difference between T-Mobile & Vodafone is.... Any ideas?

I have none, sorry... I use O2 here in Germany without problems. Unlocked in US. Activated and used a US (AT&T prepaid) SIM for a while before coming here, too.
What I HAVE learned (the hard way) is that different SIMs FROM O2 will have different APNs. I.e., O2 prepaid options have different APNs than their contracts.
My network type is GSM auto (PRL) and I don't have problems going G->H+
Hum....maybe getting a replacement phone wont help me then. Oh well its on its way already.
I looked into the APN differences but the one I used was the correct one, so that can't be the problem.
Had a long conversation with Vodafone yesterday. When they finally connected me through with an engineer this guy managed to explain it to me in this way: Vodafone has policies on what phones can be used to access their network, different models need to be accepted individually. Sometimes changes need to be made on the network. According to him this was the reason my Atrix has no internet connectivity in The Netherlands, the phone hasn't been released here and the network hasn't been tested with it.
Thing that I find strange is the fact that other providers in The Netherlands have no problem with internet on the Atrix...
Help!! I just got the phone and i have 2 AT&T SIM cards installed only the sim that i select as preferred data sim gets data service. Second sim card only receives 2g cellular service. which is ok other than the following 2 things. MMS messages need data service to work correctly and 2g cellular service is horrible in my building at work. I have tried manually selecting network but only available option for secondary sim is 2g. also tried manually setting up a new APN but didn't seem to change anything. my data connectivity and cellular reception flip when changing preferred data sim . so i know its not a sim card issue
I am not rooted
os = 5.0.2
build LRX22G.WW
KERNEL = 3.10.49-gaa8154f
1.16.40.763#1
baseband version = 202c10_10_10.0.0_151106
Do you have the option to set the preferred network type for both SIM cards separately?
It's under Settings > More (Under Wireless & networks) > Cellular network settings > Preferred Network Type
I only use 1 SIM so I can't see what additional options are available when you use two.

No preferred type is for both i have it selected to 4g/3g/2g i can select the network operators independently. once i search for network one sim gets 4/3/2g options and the second only get 2g as an option. AT&T and Tmobile are showing up
Hmm wish I knew more about this to help you out but I don't have any experience with running two SIM cards in a phone.
Have you used both of these SIM cards in another phone before and had them both work as intended simultaneously?
It could just be a limitation of the phone, maybe it can't have two separate 4G connections at once on the same network?
I'm just throwing ideas out there.

Well I am having a similar issue, I have a bell sim I would like to run as 2g and a koodo sim I would like to be the full 4g. The phone refuses dual active, only card selected for data connection functions; I can choose either, but only one functions at a time except for a couple minutes after switching via dual sim settings
---edit---
I forgot to mention, it activates during a call as well

The phone specs say it can only connect to a LTE/3G network on one SIM at only one time. The secondary SIM can only connect to 2G-GSM.

Given the phone specs. Your connection problem is caused by neither Telus(Koodo) or Bell have a 2G network. Yeah so the phone is pretty much useless to Canadians if you want Bell/Telus/Wind/Videotron on the secondary SIM.
I have used my phone (same model) with two SIM's (ATT and T-Mobile). You can enable data only on a device at a time, but it can be on any of the two SIM's. This is mentioned in the phone specs.

Scroll down to the end note.
Other phones cannot even activate the 4G on the secondary SIM.
It's a little confusing maybe to switch the data, but it can be done - from Android settings.
Ahh, well its still a sweet phone; manually switching isn't a big deal

Hi all
I'm running Pure Nexus with an Israeli provider (Golan) that provides free roaming + data in many countries.
Phone works perfectly in Israel and the US, but has problems in Europe.
On any other phone, I can solve these problems by enabling roaming in SIM toolkit.
The 6p doesn't have SIM toolkit (it has it in the system apps, but you can't open it).
Nothing I do adds SIM toolkit to the avaialble apps.
Other android phones have SIM and Network settings where you can change the settings, but the 6p doesn't (also tried reverting back to stock).
I can't register on ANY network outside of Israel / US, although once in a while it will work (it worked in Germany, but didn't work in Holland and Turkey, go figure...).
I can't downgrade at all to 3g / 2g (it won't even find any cellular networks). When trying to connect manually to networks it will immediately show me a "network unavailable" alert.
I really love this phone, but this issue is driving me nuts, as I travel quite often..
Any help appreciated

Is your device the International model (H1512)? Did you enable data roaming under System>>More>>Cellular Networks ? Lastly, dial " *#*#4636#*#* " and see if there are any toggles under Phone Info that will help you.
Hi all,
I've been having a Sprint Galaxy Note 4 that is unlocked. I bought it unlocked already. My mobile service provider is T-Mobile. I have an unlimited plan with them. The issue is that the Note cannot connect to LTE network. The only option available for me to access the internet on the go is the GSM/UMTS option under the network mode settings. Using this option my phone can only connect to a 3g service that is painfully slow. If I try selecting the CDMA or LTE/CDMA option under the network mode settings the Note will not get any service at all as if there was no sim card inside of the phone. Therefore I can only use the GSM/UMTS option. Is there a fix for this or am I stuck with 3g service on this phone? Please ask me questions if you have any that will help me get to a fix. Thanks :fingers-crossed::fingers-crossed::fingers-crossed:

I believe the LTE bands in sprint CDMA/VERIZON CDMA are different. they are not compatible with T-mobile because T-mobile required completely different LTE bands and they are locked in sprint phones and they cannot be unlocked.
If you have N910V/N910P You will only get HSPA/HSPA+ 3G/3.5G with T-MOBILE/AT&T network.
My best suggestions will be you can swap your sprint with T-mobile note 4 because N910T has more LTE bands unlocked then any other note 4 models actually more bands then international models too.
Hello guys. After paying off the remainder of my S8's bill on sprint they unlocked it (or so they said). I then used your guide to install Samsung and at&t's firmware. From there I went to an at&t store, bought an at&t go phone sim card, installed it, activated their service and changed my number. LTE works fine, but I don't think 2g and 3g are working.
1. Under sim card status it says disconnected mobile network state. My IMS registration status is not registered either.
2. Under connections - mobile networks - network operators at&t - search for at&t microcell it says "Failed to connect to mobile network via at&t MicroCell. Try again.
3. Under connections - mobile networks - access point names it says "ATT Nextgenphone", that's all. I would of thought more options would be here. ?
According to the app open signal my phone never uses 2g or 3g.
Please let me know what I should do next. Thank you.
