Network Operator connection

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.

[Q] how do i get 3g with tmobile sim

i have g tab unlocked 3g wifi us version.i took my sim out of my samsung highlight i have internet plan with t mobile it is not a smart phone.i put the sim in the tablet and the phone works butt no internet or 3g i get a message from tmobile to get a dif net plan is this the only way to get the internet wile travaling i do get the internet from wifi at home I AM NEW TO THIS I DONT KNOW ANY TERMS OR NAMES USED IM TRYING TO LEARN CAN SOMEONE HELP WITH STEP BY STEP FOR 50 YEAR OLD DUMMY THANKS MIKE

it is not going to work, best on TMOUS u could achieve is voice+edge.
Now that they have caught you, best you can get is Voice and no data plan, so u would have to rely on APs or free wifi.
This is until enough of us complain to have them either make another plan for us, or modify a current plan to allow for voice and edge. Your SGT is limited on TMOUS by hardware, so no 3G.

Phone Shows Roaming Sign When Abroad using a Local SIM

I've recently shifted to another country,
Used my o2 SIM for a day or two and obviously phone showed as Roaming, with the little "R"..
I've now bought a local SIM card and installed and running on a local Provider, yet the phone still shows as Roaming and Data does not work unless I allow Data connection while roaming...
Is this a bug or something?
I should state I've been in a different country recently and also used a local SIM from there and I never had this issue at all... I saw the local provider when using their SIM, Now, I use a local SIM and this still shows an "R" on my signal.. Same with my girlfriends phone...
Any ideas?
Edit: I'm on a N/W unlocked phone..

In my country there were 2 networks, and when a third network started it's business, it was using the infrastructure of one of the existing networks. The phones that were using Sim cards of the third network, all showed that they were in roaming, and if they wanted to use data, they needed to enable "data while roaming" options. Of course, they were never billed for roaming charges. Now this third network has it's own infrastructure, and the roaming sign is a thing of the past.
Maybe this is the case with you too.
I would try to contact the local network provider, to seek the answer you are looking for.

I get this in Thailand because my provider has different names/IDs for the 3G and 2G networks.
The 3G is called "True-H" and the 2G "True Move", or something like that.
The SIM will automatically register on both networks, but if it connects to the 2G network I get the roaming symbol.
The solution is either to enable roaming data (I don't get charged any extra, but need to remember to disable it if I travel), or set my movie network to WCDMA only. This way it won't connect to the 2G network.

Check if you got roaming allowed and switch it of.
Register if needed handset on your network manually.
You might not have the network where you are due to availability area coverage.
Check your apn settings, if they are on the mobile network you need and settings are correct. Perhaps from website provider, or helpdesk you can request them to send settings.
Go to settings, more, mobile networks and check there. Just explore a bit.

Cheers for the replies,
I'd already checked those areas out, APN is correct, Settings from Provider received and installed, Manually selected provider from the Network list...
Still showing 'R' - AS has been said 0 I'll just have to enable Data when Roaming and turn it off when I travel..

which service provider do you use and phone model do you use?
this phenomenon normally happen in new telco on some phone model

Flash Sprint note 8 to work on Verizon

I have a sprint note 8 and ive tried to follow the guides to flash unlocked firmware and keep getting sha256 error. I put my Verizon SIM card in and it works but it is always roaming and Verizon said I don't have a phone active on my account. I don't know if there is a way to fix it and I'm super frustrated trying to flash unlocked firmware trying to fix it any help would be appreciated.

If the phone has a clean IMEI it will work on T-Mobile, Metro PCS, AT&T, Verizon Prepaid (PagePlus) or any other GSM carrier in the US and worldwide, Phone will work on Roaming State , Make sure you add your Carrier APN for the Data settings.
Sounds like you are stuck in roaming state nothing you can do about it.. I bought the unlocked model cause I figure it's best to bout be carrier locked

What do you mean by roaming state?
Surely roaming state is when user roams onto a different network other than their own. Example, T Mobile customer travels to Spain and roams onto Mobistar Spanish cell network using his or her existing T Mobile sim card regardless of what the device is.
Perhaps that's how it works between the two USA cdma carriers? - the way you mentioned it.

So fp r short you are using sprints towers on Verizon's network is what I believe read below
roaming is a term used to describe the ability of phones to connect to the network of a different carrier, abroad or at home in order to offer users the same features they use while on their “home” network – making and receiving calls and text messages and surfing the web. Roaming is possible thanks to the international agreements carriers have with other carriers, in order to offer their wireless services in other regions of a country or of the world.
