I have a straight talk AT&T micro-sim that I was using in my wife's AT&T iPhone 4 (unlocked but shouldn't matter) which was configured with the att.mvno APN. 3G data and MMS worked wonderfully. Now I have taken the same SIM and put it into a T-Mobile HTC One S and I cannot get 3g, let alone 4g, data to work. MMS is functioning and 2g data works. I have unlocked the bootloader via the HTC Dev method, rooted the stock ROM, and I have SIM unlocked the phone using ascot17's method on this site (http://forum.xda-developers.com/showthread.php?t=1693491). I have tried the att.mvno APN setting (works, but only 2g data) and the newer tfdata APN setting, which gets me NO connection at all. The funny thing is, when I reboot the phone, it shows 4G data for about a minute, and if I run the speedtest app, it gets 4-6mb down speed which is about right for 4g in my area (Janesville, WI). After about a minute, it switches to 2g. I have also contacted HTC (no help, they say it's a network issue) and Straight Talk (no help, they walk me through APN changes and then claim I need to contact the manufacturer). Has anyone had any luck getting the One S to use 3g or 4g on Straight Talk? Would I be better served to get a T-Mobile SIM? Is it worth trying to flash a custom ROM instead of my rooted stock or is that a waste of time?
Thanks in advance for any assistance!

For some reason my Sensation 4G(TMO-US) won't data roam on AT&T network. Any ideas?
Here's the current situation... 2g is all I can get at home. My 2g icon is showing but NOTHING that requires data will work. I'm roaming on AT&T because I'm outside the city, and voice and text work just fine but when I check my data roaming via *#*#4636#*#* it says not roaming. YES I HAVE DATA ROAMING ENABLED. My gf has the Exhibit 4g and has no issues... When I put her SIM into my phone data works just fine. I've called T-mobile and they claim our phone settings are identical and data roaming is enabled on their end for my SIM but when i put my SIM into her phone it won't connect to 2g. I've removed the battery and SIM, toggled ciphering, had then rebroadcast my number and still nothing. AND YES it's a new SIM card, actually the 2nd one and Tmobile 4g and 2g work just fine as well when I'm in their service area. Any help would be appreciated since T-mobile doesn't see this as a big enough problem. Can I somehow enter an APN for ATT? I'm really out of ideas.

I have the same issue did you ever find a solution?
Tmobile had to have a tech rebuild my profile for their network. Took about a week or so. Everything has been fine since.

unicoyo Thanks
I am going to try this, but I wanted to point out that I don't have the 3G/4G Plan from at&t, I have the old edge plan or media net plan--

Kind of defeats the purpose of having a top of the line 4G phone to be using it on EDGE doesnt it?????

1700 band.....
don't worry, in a year or so, (after the hostile take over) there will be devices that support the whole spectrum that TMO & ATT supports

i was thinking the same thing, after att takes over..probably the new devices will have a wide 3g/4g spectrum, att has alway says that they need the aws from tmbile 1700/2100
Seeing as inzaneip has a Fido (Canada) symbol, I would not be surprised if this "Sensation 4G" is actually the Bell Canada model that works full speed on AT&T.
Another thing it consider is that if you do manage to get the HTC Sensation 4G (Bell/ Canadian Version) that has the 850/1900 Mhz bands, will ATT detect that you are using a smartphone and automatically give you the 30 dollar 2GB limited data plan which you cannot get rid of?
I currently use a Samsung Vibrant on ATT and only have a 15 dollar unlimited data plan. However the Vibrant has 850/2100 Mhz bands in which the 850 mhz is the onle that i use to get data. However, I feel that data fluctuates way too much from location to location. It jumps from edge to 3g to 4g back to edge within a block. Also, there are known reception issues with the Samsung Vibrant (kind of like the death grip on the iphone 4). I am also one of those people considering a HTC Sensation 4G (bell version) or the HTC Incredible S as a substitute IF ATT does not charge me the 30 dollar limited data plan.
Shouldn't happen
I got away with the dumbphone data plan for a long while on my Nexus One until Google gave AT&T the IMEI numbers and they realized I had a smartphone... So as long as AT&T doesn't recognize the IMEI it could be a Motorola V3c with some wicked data usage for all they know!
Do you think ATT will recognize the Bell version of the Sensation because the HSDPA runs on the same bands and I think it was either Bell or Rogers that had some relation with ATT? Not sure if they gave ATT the IMEI numbers though...
The general pattern seems to be:
If your unlocked phone is a model NOT sold by AT&T in the USA, nor is it an iPhone or Nexus, then AT&T won't recognize it as a smartphone.
If it's a model also sold by AT&T, albeit from a Canadian carrier (e.g. a Bell Atrix or Rogers Infuse), there's some chance they might recognize it. The Sensation and the Incredible S are probably safe.
Also the TMo Vibrant has 1900 3G but not 850. It has poorer building penetration than 850, so it's not surprising that the 3G drops out a lot.

That sounds pretty practical. I'm looking to buy an HTC phone that has both the 3g Bands for ATT. But with that vague merging between T-Mo and AT&T, not sure if it would really matter in the near future.
The merger should not affect compatibility of phones that today already work on AT&T 3G. Be aware the Bell Sensation does *not* have the T-Mobile AWS band if you were thinking you wanted something for both networks at once.
Yea, I'm well aware of that. T-Mobile sucks around my house because I have a big tree in front. I'm only concerned about AT&T but thanks for the warning.
Hi All,
Is it possible to force data roaming to pick up an ATT 3g signal? I have Tmo but only edge where I live, and for $30/month data edge just isn't going to cut it!
I have messed around with "service mode" to select a specific band frequency, but I either get edge or no service at all.
On a side note, my sgs4g is unlocked and I was able to get 3g when using a straighttalk sim (again ATT signal). Is it possible to get connected when using a Tmo sim?
This could save me a HEFTY E.T.F. .... :/
Not sure or it's possible, but my suggestion is that you flash modems from this thread http://forum.xda-developers.com/showthread.php?t=1192436, lemme know if anything.
Hi All,
I have my unlocked SGS4G with a Straight Talk SIM inserted. I can make calls and send/receive texts, but I can't seem to connect to 3G data. By default, the SIM seems to have wap.cingular as the APN. This gives me no data at all. When I switch the APN to att.mvno I can get edge, but no 3G.
There are 2 kickers to this:
1. When I lived in TX I tried the same thing with someone else's straighttalk SIM and I got 3G no problem using the att.mvno APN.
2. When I have the ST SIM in my nokia E71 (also ST) I get fast 3G internet. (But when I pop it in the SGS4G the MAX I can get is edge).
Does anyone have an idea of how I can get the 3G working? I have tried using a few different APN settings with no luck, but at this point I will try just about anything you throw my way!

Thanks for the tip, but those APN settings result in no internet at all. I do have an active T-mobile account to use the SGS4G on currently, but it roams on ATT in my area. So I'm thinking that simple mobile isn't supported here.
Does anyone know the exact APN settings from a current Nokia e71 for straight talk? When I try to access them, the software tells me I don't have permission to view it.
Solved (I Think)
I think I have found why this won't work in my area, but PLEASE correct me if I am wrong!
It looks as if the SGS4G does not support 3G on 850 MHz while the nokia E71 does.
Apparently where I was living in TX, ATT was transmitting 3G over 1900 MHz which I could pick up, but now in NM ATT uses only 850 MHz 3G so I am SOL.
Now I'm assuming that this incompatibility is strictly a hardware issue, hence flashing new modem FWs will not work. Is this right?
Right. This phone doesn't support 3g over 850mz, only 1700/2100 and 1900. Only 2g at 850.
This is a hardware limitation so no ROM can change it.

KJ, what APN settings are you using? I went through half a dozen before I finally got the right ones. Also, any idea what the exact model of the phone is?
I used the more popular ones, I think.
apn
wap.cingular
[email protected]
Wireless.cingular.com
I've found by selecting the other carriers in the connection setup some things start to work.
How do I get the model #?
It's is sim free from UK. No branding but behaves as if its branded
What apn worked for you for windows 8 and at&t 3G?
Search doesn't work consistently on mobile 3G on at&t. Not happy with purchase.
T-mo works well but using 4G t-mo service. No issues.
Try this one;
MMS APN
Access Point Name: pta
WAP Gateway (URL): proxy.mobile.att.net
WAP Gateway port: 80
MMSC address: http://mmsc.mobile.att.net
To find the model number go to Settings>About and it's under phone information.
The problem with the unlocked phones is that even though they are unlocked, they still have the original carrier firmware and as far as I know, there are only a couple of models that you can flash with a stock HTC rom. You may be in luck since it is a European model. You can take a look at this thread http://forum.xda-developers.com/showthread.php?t=2137556.
Anyway, good luck to you. It's a great phone.
