I own a t-mobile version of the nexus one. I can connect fine to their network with no problem, however i do find myself in a complete t-mobile dead zone sometimes. When im at that location other people with AT&T devices have pretty good service. I noticed that in the Wireless & Network settings -> Mobile Networks -> Network Operators, it does find AT&T on there. However, when trying to connect to it, it gives the following error:
"Your SIM card does not allow a connection to this network"
At that location, i was also with someone who had t-mobile with a Motorola Cliq, who was able to access this AT&T network without a problem (although it was a G connection)
Is there something i can do to access this network with my phone and sim card?
Maybe some sort of sim unlock code i need to get from t-mobile?
same here/..
actually.. im having that problem right now! O.O;
I have full bars yet i can't send txt msgs or call anyone.. and when i try to turn on wifi it says updating wifi then turns off... wtf?
anyone have any ideas?
Are you on a pre-paid account? Sometimes the pre-paid accounts do not support roaming (even though you aren't paying roaming on a contact account).
Also; it depends on the freq of that network. Ummm; if the phone is unlocked or not.
There could be a number of issues. You could try and call T-Mobile and ask them. But it just could be that it's At&t and that specific area might not be roaming enabled.
Just my 2-cents.

Check your logic. I'm sure that roaming would be enable in big NYC. WE are in two different areas also. Plus I am on postpaid. Also the phone is QUAD band, it does not need 3G to roam on AT&T EDGE network...come on now.
I ended up contacting google phone support about this. The tech i spoke to on the line was able to recreate the issue.
When he contacted t-mobile support for us t-mobile said basically if they own the property rights for the area you're in (disregarding your signal strength) you are unable to connect to any other network. If you are outside of a t-mobile coverage area, you are then able to roam.
I wanted to use this phone as the data only device. I changed APN setting to AT&T Broadband, but I only get HSPA or HSPA+. The Sim has been used with the LTE hotspot device without any problems and it still works fine.
According to the forum, many people had reported that AT&T's system has a problem with this phone since it recognize Xperia Z3c as 2G phone, so they couldn't get LTE.
Some people managed to resolve this problem by telling to AT&T previous LTE phone IMEI, but I can't do that because of this iPad Unlimited Data Sim.
I know my case is really rare, but any advice will help.
Thank you in advance.
Hi I bought an unlocked, Verizon branded Moto X Developer Edition which I intended to use on Koodo in Canada, which runs on the Telus network. When I put my sim card in it has trouble connecting to the network. It connects for a couple of minutes, and then loses the signal for a couple minutes, then picks it up again and so on. It's like it is connecting to cell towers other than Koodo/Telus and cant use them.
I have tested the sim card in another phone and it is fine. I have spent a significant amount of time with Koodo customer support and it has become obvious the problem is with the phone. It doesn't matter if I have it set to global or LTE/GSM and connect to Koodo that way, both have the same result.
Has anybody run into a similar problem? I absolutely love the phone and would hate to find out that I can't use it. I live in London, Ontario and shouldn't have any issues with coverage.
Thanks
I have The exact same problem with a moto X from ATT trying it on Koodo. Maybe flashing the Telus rom or dev rom on it could work. Mine is in 4.4.4 with ATT so I can't unlock the boot loader to do that but maybe you can...

Have you tried manually entering the APN settings?
The Verizon XT1060 (Dev Edition, or non-Dev Edition) is SIM unlocked out of the box. So forcing to GSM mode should work, as long as the APN settings are right.
As a side note, to use a T-Mobile USA Sim, I've had to manually enter the APN settings on my Dev Ed VZW X.
Just switched from verizon to tmobile. Thought I can just pop the sim in, adjust APN and be good to go but it didn't turn out that way. Two major issues: only getting 3g connection and unable to activate hotspot. Phone is not rooted but can root it easily. Are there stable fixes or should I just sale and get a tmobile phone? Thanks

There is a particular G4 model (H811) which has the highest compatibility with T-Mo US. So do you have that one, or something else? (eg the Verizon-specific model: VS986)
The H811 is 100% compatible with Tmo, the Verizon model is probably barely compatible. (Verizon's network was historically based on CDMA, and regular voice/SMS still travels on that network, unless you have VoLTE working on your device)
Also, you do not get hotspot capability on any T-Mobile plan. Currently I have 2 T-mo phones, my daily driver at the moment is still on Verizon. So I have a low-end SIM for T-Mobile (infamous online or Walmart $30/mo plan) which includes 5GB of monthly data but you cannot do tethering/hotspot with it.
So I got a Chinese edition phone with band 2, 4, 5, 12, and 17 to fully support both TMobile and ATT network. The Global edition was missing band 17 for ATT so I didnt want to go that route. Been going back and forth with ATT a bit for the past few days since my device came in. The phone shows up and an "unknown device" on their network when we tried adding the IEMI. It will get UMTS (2g) and HSPA+ (3Gish/4G), but will not connect to any LTE or GSM. The phone supports GSM fine, so its strange that it wont do normal cellular connection over that, it will only do cellular over UMTS. The device wont detect as an LTE device and so the sim wont activate LTE on it.
Anyone else with ATT have this issue? And were you able to resolve it somehow?
Or those with TMobile in the US, are you able to activate the phone fine and get full coverage and LTE working?
I messed around with the connection settings in the *#*#4636#*#* menu. Only the "LTE/TD-SCDMA/UMTS" and "LTE/TD-SCDMA/WCDMA" will work properly at all. Both options give me UMTS for cellular, and HSPA+ for data. Of the 4 APNs that ATT uses, only the "ATT Phone" will work at all. The standard LTE APN "NXTGENPHONE" will leave the phone with no data or cellular service. This is related to the phone not being detected as an LTE device and the SIM not activating as such.
I simply put my AT&T sim in my China version and it worked straightaway. I didn't have to do anything else.
I am on Cricket, which leases service from AT&T, so I should know if it works once it comes Tuesday.
Just for perspective, I got a EU version of the Mi 9. Popped in a T-Mobile sim and it worked out of the box. Try the other sim slot. Could be your sim card if not.
Try these codes in Dialer. See if that helps anything.
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
I was just making an ATT account so no previous activations or sims. So that could be the issue. I will try activating a sim with an old phone and then move the sim over. Or since it is the same hardware as a Galaxy S10, ill see if I can find a store that will activate a sim with a floor model S10 and then let me swap the sim into my Mi 9
Straight talk (ATT sim) lte without issue. no programming necessary , I have the global model though

Where did you guys buy the China version from?
US mobile white SIM from starter kit (T-Mobile) works well with LTE on Chinese model of Mi 9. Black one (Verizon) technically works, registers in the network and enables data, but Verizon refuses the IMEI as non-certified brand of the phone. Trick with activation on the iphone first and switching to xiaomi did not work, service gets cut off, when trying to make a call, it keeps dropping. AT&T based: Cricket and Straight Talk work just fine too.

Thanks for the info.
I was wondering about Verizon, since it support some CDMA bands and support 2 out of 3 of the LTE bands they use (doesnt support B13). Unfortunately I never tried it myself since half the coverage near me uses the band this phone doesnt support on Verizon.
I went and got my ATT account updated to an old Nexus 6 IMEI number and it got LTE on the N6. I then took the sim and put it in my Mi 9 and now the Mi 9 has LTE. So for anyone just getting this phone, you must have an IMEI on your account that is recognized as an LTE phone. If you try to add the IMEI of the Mi9 it is not recognized by ATT and wont provision LTE.
IMEI spoofing does not work with Verizon, as they simply ban the device. They call it “non certified”. Bands are seem ok.

I been purchasing from liaow. Never ran across a issue with them
I've been having the same issue, with a recently-bought (last week arrived) Mi 9 Global on AT&T postpaid. LTE showed up and worked fine day one, now network speeds are dropped down to 3.5G speeds. Anyone else have success with getting LTE on a fresh SIM?
