On Another Network - AT&T Samsung Galaxy S II SGH-I777

So I have me an Orange- UK sim card coming. My AT&T Galaxy S2 Is unlocked. I was wanting to test this in the states before everything. Its Prepaid but Orange Prepaid WORKS on T-Mobile in the USA. Since Network Selection is locked down Is there anyway to Select T-Mobile? Cause I know network secltion is locked. And yes the Phone is SIM UNLOCKED so I know it will take the sim card. its just will it connect to the T-Mobile Network?

It will work for calls. But Internet will only be edge. 3g and 4g(h+) for tmobile are run on a band this phone doesn't have.

But would my phone be able to get on the T-Mobile network at all since I can't select networks? And also idk about the att version but the T-Mobile galaxy s2 has the ATT 3g bands. But data does not matter. I just needed an UK number here in the states so calls and texts are just fine. But would it easily connect to the T-Mobile network without selecting it? Since it won't let me

Just do a search for tmobile apn's. Putting in the right apn will 'select' your carrier. Calling and internet will work fine. Just limited to edge. Tmobile phones are 100% compatible with at&t networks.

Sense it is similar unlocked it is network unlocked. Once you put your similar in and reboot it will go through the network set up again saying it detected a new similar card. After that it will connect fine. As for the data he is right the ATT version only supports ATT 3G or better bands, but as you said the data doesn't matter. If it doesn't automatically go through you can go into settings and select wireless networks and there is an option to scan for networks. Just select T-Mobile if that is what your carrier will run on. Not sure how it will react sense it will be roaming on that network though

On the att galaxy s2 it won't allow u to do network scan it search unless running miui rom

It would if your sim card prefers T-Mobile network. Although you can't manually select networks, SIM card contains instructions as to which network it prefers to use. There is really no need to manually select networks unless you don't like what the SIM carrier prefers.

(Q) US Tethering on a Bell Atrix?

Alright..I'm running an unlocked Bell Atrix on the Telus network..and was recently down in San Diego where I purchased a Tmobile SIM card for use while I was down there (and so I could Hotspot and have the wife boost off my wifi for her phone).
When I attempted to do this however I got a notice that I had to enable this thru my AT&T provider. Obviously it was a Tmobile sim card using tmobiles APN..so I'm not sure why it was prompting me to contact AT&T. Does anyone know a way I can get around this for the next time I'm down in the US? I'll be going to Hawaii in Sept and really want to be able to tether so all my Canadian companions can boost off me..
you'd only get 2G off t-mobile
maybe try getting an ATT sim card?
rebellus run their 3G off the same 850/1900 frequency as ATT
regardless, t-mobile's data apn probably didn't get added. try adding them next time.

I had data..and I'm not sure if it was 3g or 2g but it was quick enough that I didn't notice any difference. The problem is at&t doesn't sell prepaid sims with data..that's why I went with tmobile. I had the apn's configured appropriately otherwise I wouldn't have been able to get any data..which I was. I just wasn't able to tether..

Galaxy s2 i9100 not running on 4g.

Hi, I have a white galaxy s2 i9100, but for some reason, when I put in my Tmobile sim card, it only runs on E network and not 4g. I contact Tmobile and they said there's nothing they can do about it since it's not a Tmobile phone. is there anything I can do to make my phone run on 4g? E network is very slow.

The I9100 version don't support 4G
But it says on the website that it does

Im looking at the specification and i don't see any 4G.
I order mine on newegg.com before I purchase it I checked the specifics and it said 4g.

You're on T-Mobile? In the US? Then what you're seeing is normal. The GT-I9100 doesn't support one of the frequencies necessary for 4G on T-Mobile USA's network. (1700/2100) It will ONLY ever get Edge speeds.
It DOES support 4G (well, HSPA+, anyways) on AT&T's network, which runs on 850/1900.
See here: http://www.newegg.com/Product/Product.aspx?Item=N82E16875176292. Once you get to this page, click on the Details tab. Notice where it says "3G". (I know - 3G; but it uses the same frequencies for HSPA+) It says "AT&T 3G Only".
Sorry bud.

A lot of carriers wrongly named their network 4G for advertising reasons when it is in fact still only 3G.
The reason why it might be on EDGE is because it probably has a much stronger signal than 3G does so it will default to it. You can set the phone to use 3G only by going to settings -> wireless & networks -> mobile networks and then set network mode to WCDMA only.
Take note of the signal strength in settings -> about phone -> status.

No. This will NEVER work. Trust me. the I9100 does not and will not EVER receive one of the frequencies necessary for T-Mobile USA's HSPA+ (what they market as 4G) network. You will ALWAYS only be able to get Edge on T-Mobile when using this phone.

Sorry, I'm use to the 850/900/2100mhz 3G frequencies we use here, all of which this phone covers so there's never a problem using any network... Except Vodafone, they suck on all frequencies

Using another carrier at will with ROM for better reception?

I feel pretty stupid asking this question seeing as I put this ROM on myself and ought to know everything about it. It's Neutrino GT for the Atrix 4G. I have AT&T for my provider, and I have poor reception at my home. I recently had to switch to my backup Atrix with the ROM, and I noticed that it is using U.S. Cellular, which provides full EDGE reception. Obviously nothing amazing, but still better than what I was getting with AT&T. I also have the option of using T-Mobile.
My question is..Is this only possible because of the ROM, or is there another piece of android development that allows this to happen without actually roaming? I want to get another phone and be able to have this option, but I need to understand how it's possible to have the option to use other carriers at will.
Where did you get your backup Atrix? It has been SIM (network) unlocked if its an AT&T and you can use it on other networks. That's not the ROM.

I bought the Atrix off eBay long while back, and I did unlock it. Although my SGSIII GT-I9300 only seemed to be able to connect to the AT&T carrier (unless roaming), and not have this option. Additionally, I have an AT&T SIM in it. Unfortunately I'm not allowed to post a picture yet on my post being new, but under Settings > Mobile Networks > Network operators > Available Networks, it will list AT&T, AT&T, U.S. Cellular (or USA Unicel), and T-Mobile. On my SGSIII, it only listed the two AT&T networks. This is all with just the AT&T SIM in it. If you dial a wrong number when it's under U.S. Cellular, it will even go through the whole "Hello, this is U.S. Cellular..The number you have reached..." bit.

[Q] Roaming Network Problem

Hi,
i have Motorola Photon rooted and unlocked, i live on the border with Mex also i have this phone with a Mexican Telcel SIM Card, works perfect on Mex, but when i back to USA i lost the Mex network and the phone start to search for networks and i just see Sprint network, but i can't receive or made phone calls on sprint network roaming, if i remove the sim card and put the sim on my HTC i can see more networks, sprint, AT&T, verizon, etc and i can go in to roaming and works perfect, i can made and receive calls on roaming, but if i back the sim to the Photon i just find a sprint network only and the roaming service not work..
what can i do to see more networks on my photon?? i need receive calls from mex on this phone..
thanks in advance
You need to flash the kddi radio. That should fix your roaming issues. After that you need to set the mobile network to GSM only

Does the Verizon V10 provide 4G LTE using a T-Mobile SIM card?

In the G4 forum, we realized that Verizon has put some sort of firmware on the device that disables 4G LTE in GSM mode using a T-Mobile (or AT&T for that matter) SIM card, even though the phone does support the bands. When the phone is switched to CDMA mode, then 4G LTE works fine, but unfortunately voice doesn't work at the same time. See this thread here for more details: http://forum.xda-developers.com/verizon-g4/help/lg-g4-vs986-t-mobile-lte-problem-t3195888
Can anybody try out the same with the V10 and report back? Would be intersting to know if Verizon now intentionally started crippling these devices (since it used to work fine on the G3), or this is some sort of bug that only applies to the G4 right now. Thanks!!
I use a VZW branded V10 with my tmo sim and can only get H or H+. Rarely does it get 4gLTE. And when it does sms does not work.
Thanks... but you do get 4G LTE sometimes when in GSM mode?!?
Can you change the system mode in the mobile settings to CDMA and check if it gets 4G LTE with the T-Mobile SIM card? And then in the same place switch it back to GSM and see if it falls back to H+ only? That's the behavior we saw on the G4, like Verizon is intentionally blocking LTE om GSM, even though the phone supports the band.

I am not sure if it is the same with Tmobile, but when trying to use a Tmobile variant on AT&T, LTE does not work either. It seems that you have to get the device provisioned by the carrier for LTE using it's IMEI, not just doing a SIM swap.

Yeah if i switch to CDMA, i get 4G LTE very often though i cannot send message or call
Can anyone tell me if u get the annoying unauthorized sim card message... if so can we stop it from appearing. Had that issue with my verizon htc m8.
I tried at a T-Mobile store earlier to see if one of their Sim cards would work in my VZW V10 and I had the same issues.
The pop up saying "not a Verizon Sim" or whatever came up after a few minutes of dismissing it as well.
When it first loaded up, I changed the APN to match the in-store display V10 with its exact settings. I changed the network mode from global to LTE/GSM and after a minute it showed it was connected with 4G LTE, but it went away after a few seconds. I couldn't get it to come back, and it only had like 2-3 bars, and H for data. I know it wasn't from lack of signal because the display V10 had full bars with LTE.
I also tried sending a text using the T-Mobile SIM to one of my other numbers, but it didn't go through at all. Didn't try placing a call, but regardless it didn't seem like it would be worth it to switch.
No 4g LTE
Still waiting for a fix,can get no 4g LTE on t mobile,I'm on marsmallow so I lost root access
I'm Canadian, I just bought an unlocked Verizon V10 on ebay and I'm planning to use it on a Canadian carrier. Does this mean I should expect to have no LTE data at all on this phone in Canada? Poops I never would have bought it if that was the case.
Let me know, I may try a return without opening the package.
how different is the speed between HSPA+ and LTE? is it noticeable
does it bother you that its not LTE?
I bought a phone from a seller on swappa. when he listed it. the phone had a clean ESN.
took it to the verizon store to setup verizon prepaid and it was flagged a non pay account
cannot activate.
I am using my ATT sim card right now
I can return it but on the secondary market is many LGV10 phones are going to be flagged for non payment when the accounts go into collections, it then buyers could get screwed.
I might just stick with the phone. But i can never use it on verizon. I have to wait for a Root on marshmallow, and fix after that if I want LTE speeds on ATT or TMO
I got LTE working. In happy with it. I think the US phones work in Canada even with a bad imei.
Another area on a long long laundry list where canada is better than the usa. hockey and standardized healthcare being 1 and 2... hahaha
I was having the same issue on my Verizon v10 vs990 on my T-Mobile network. I went into the APN settings and set it to LTE/CDMA and it works perfectly. Calls, SMS and data.
