Have Unlocked T-Mobile Sensation - using AT&T

Went into T-Mobile yesterday and purchased a Sensation off contract. Got home and went online to get it unlocked.
Currently the phone is on AT&T and I can report that 3G / 4G service does NOT work. I know there was some talk about the phone maybe picking up the 1900 3G band - but I can confirm that is does not. It only works on the 2G / Edge network.
MMS / SMS work fine.
One MAJOR draw back to having this phone on AT&T is you cannot be talking on the phone and use data at the same time. This caught me by surprise when I was using the Google Navigation app and got a phone call. The map stopped updating until I got off the phone. I double checked trying to open a website while on the phone and it gives you an error message saying it needs a connection.
If anyone does plan to do this - know that you also have to manually put in the AT&T APN settings for internet and messaging to work. Just typing in the unlock code will allow you to place calls, but no other services work.
Another annoying part is there is a T-Mobile app that updates all your contacts with their servers. This is constantly trying to update throughout the day. The program isn't able to be un-installed at this point either.
I called AT&T to give them the IMEI number. They (obviously) don't recognize the phone and register it as a non-smart phone. At first when she said that, and also told me my unlimited data package would go from $30 to $15 I was happy. As soon as I got off the phone with her and reset the phone, the internet wouldn't come back up. Had to go in to an AT&T store to get it all fixed. They had to put the IMEI of my old Inspire 4G back on the account to get everything working again. So - don't call AT&T with the IMEI =)
So - would I do all this again and spend $600 bucks. No way - its not worth it. The phone itself is nice, but I feel like I just got tossed back in time about 15 years with this incredibly slow internet and not being able to "talk & surf" at the same time. I've put the phone for sale online
Take it for what its worth

Having only Edge connection speeds just kills the entire experience on any phone regardless of how hardware/software advanced it is. Don't you guys have the Inspire? With all due respect, why would you think the Sensation would even work to it's full potential on an entirely different 3G network? Just wondering why you would set yourself up for such an expensive let down? Again no disrespect, just wondering.

It's still within 14 days . Just return it and get your loot back dude. Thanks for experimenting and posting your results for the community. You've done your part please go return it!

There was talk that even though the phone didn't have the 850 band - it may still work on the 1900 band. No one knew for certain (at least in the posts I have read). I read online about other makes of phones that were able to get 3G on just the 1900 band - but the Sensation doesn't seem to.
It's not a huge let down - and the money isn't wasted. I have 14 days to return it, granted with a $50 fee. So it was worth (to me) a $50 experiment to perhaps get a better phone than the Inspire - not to mention its quite a bit smaller which is a huge bonus for me!

Wy did you ever do this? The sensation with at&t 3g will be released on July 5th thru Bell in Canada and already many major import sites are taking pre-orders. It's also confirmed that the bell version will be bloat free and have pure HTC ROM on it.

It's just money man! With a return policy and able to pick it up 2 blocks from my house it was worth the gamble! If it worked on the 1900 band, I was golden. If it didn't, I'd return it or sell it on craigslist.
I imagine the Bell version is going to sell for ~$150-200 higher online because it has the 850 band - supply and demand on that phone will be quite high as compared to the T-Mobile version. I'll most def. keep my eye out. Do you have the name of the website that is doing pre-orders on the Bell Canada version? Not finding anything online.

I hear ya... Worth it to try if you can get a full refund. This is the site I pre-ordered from. The price is high but will be worth it. AT&T service is WAY better in my area. I only get edge on T-Mobile @ my house or I would consider jumping ship.

You could have gotten an SGS2 for about $150 more and had 4G speeds (21MB) on AT&T and used the same dumb-phone data plan. There's a guy with an SGS2 on T-Mobile U.S. in the SGS2 forum getting EDGE too. What's the point of a high-end phone that's dependent on data on a low-end network?

WOW!! $899.99 for the phone. That is A LOT man!! I could keep the Sensation I have and use it on 2G only - and have 450 bucks in my pocket. I have an Inspire sitting here next to the Sensation. Inspire is on "4G" and the Sensation on "2G". In real life tests - it takes about 1.5 seconds longer to open a website such as CNN.
The more I use the Sensation - the more I like it. Its quick - the screen is fantastic - and I'm learning to enjoy having 2G because my battery is lasting quite a bit longer than the power hogging 4G service.
This may not be a bad thing after all....

Correct me if I am wrong - but isn't the GSM bands the exact same on both phones? The only difference is the UMTS spectrum which is for 3G / 4G data. I was under the impression that the voice services of the phone (ie: making phone calls) is always done via GSM.
Edge at your house via T-mobile - don't you have a wireless router the phone would connect to anyway?
(I'm starting to feel like a sales person for the T-Mobile version now - this is scary)

You do realize that it may still work on the 1900 band, but your area is in 850 towers right?

Thats what I was thinking. ATT uses 850 for 3G in my area.

I'll def. be on the lookout for the 1900 band to see about 3g connectivity. I live in Phoenix, AZ.

Ended up getting rid of the phone and waiting for the Canadian version with 850/1900
Too much money to spend on the phone with such limited capabilities. Could never get it to connect to 1900 MHz 3G from anywhere in Phoenix all the way to Tucson.

Wow is it really worth it to cough up 900 for a sensation? That is alot. I always looked to import a NAM version of smartphone to utilize my media net plan. I will have to just wait it out for a Nexus 3 maybe. I love tech but paying 900 for a phone is little out there for me.

good very good

Can anyone tell me the apn settings for att mms? I updated with what I found in Google, but mms still doesn't woek.

I, for one, really appreciate taking one for the team. I was also curious as if it would work on AT&T's 1900 MHz band. We already know the 850 MHz wasn't listed.
Just an FYI, the only phone that works on 1900 MHz (as well as AWS) is the Vibrant (I have it now). If you're wondering if your area has 1900MHz coverage by AT&T, you can always use the Vibrant as your benchmark. I keep a Vibrant around just for this reason. I love having a phone that works with both AT&T and T-mobile 3G.
For those criticizing why not wait for an AT&T version: because some of us are interested in phones that can work on both GSM carriers here in the US.
Vibrant is confirmed, not sure about Galaxy S 4G (or really a Vibrant 4G). Of course there's the Nokia N8, but it's not an Android phone.
Some of us were excited to see if the T-Mobile HTC Sensation 4G will join the ranks.

Just so you know, the restocking fee does not apply to cancellations, only phone swaps, unless its defective, then its fee also.

[Q] NO HSPA+/Only EDGE on Simple Mobile

So I bought a Samsung Infuse off Craigslist. I love it, it's awesome. I use the Simple Mobile $60/m plan. I previously had a Samsung Galaxy S Vibrant before the Infuse. I used to run CM7 but used Bionix 1.31 as my ROM on my Vibrant. So I'm familiar with the ends and outs of this technology.
The Situation: Samsung Infuse running latest "unofficial build" CM7, flawless performance. After doing much research as to APN settings on Google and XDA I found that the internet is wrong with the APN settings for HSPA+ on a HSPA+ capable phones. I called Simple Mobile yesterday and we did an OTA (she spoke I listened) configuration of the APN and it's full of IP addresses nao. She said that will allow me to access the "4G" network. The thing is, it says "E" for EDGE at the top for my signal....consistently.
The Problem: The EDGE never changes, also according to various speedtest's I can't EVER break .50kbs DL speed off of WiFi.
So I tried switching out various modems that we're available to me for the Infuse via the CWM flashable's. I've seen NO IMPROVEMENT on data speeds after each modem.
So what exactly is the issue: Am I doing something wrong via XDA material? Or am I just ****ed on HSPA+/4G speeds?

Simple mobile use tmobile towers, so u'll never get anything other than EDGE because att&fee phones dont use the same bands

You are right and WRONG all at the same time...fascinating isn't it!
Simple Mobile does in FACT use T-Mobile Towers, however; before I rocked the Infuse I've seen other speeds that read 3G/H. The Simple Mobile Network offers 4G/HSPA+ with the $60/m plan that I am currently on.
So with that information, how would you explain that a phone that is HSPA+ capable and programmed correctly that sits on the EDGE network and still doesn't break .50kbs DL speed??
I spoke with customer service at Simple Mobile and several other Simple Mobile retailers that told me up one wall and down the other that the Samsung Infuse programmed correctly should FLY without WiFi, this phone should act like the rocket it claims to be with data on the network.
Instead it is slow, sux and is worthless without WiFi.
So how come you tell me one thing, and several people that work for the Network and people that are affiliated with it tell me another?

I own a business; I know about selling. But according to my research, your a little or alot off; I just can't exactly prove it.
I know that AT&T offers 4Gish speeds (true LTE in like 2 cities in TX), and that T-Mobile offers 3.5+G-4Gish speeds.
I also understand the concept of up-selling, however that scenario does not apply with my current plan and situation.
Has it, or has it NOT been documented ANYWHERE that an HSPA+ capable phone on the $60/m Simple Mobile plan achieved true or realistic data DL speeds off WiFi?

I am no tech or anywhere educated in this topic. But why are you comparing network speeds with your wifi? Or am I missing something here?

I'm not using WiFi as a comparison, just as another option for higher DL speeds. Off WiFi I've seen snails crawl faster than my data can move.
I just want to know why I can't get anything better than **** with this great phone and supposedly "reasonably-good" network.

They simply dont know wat they r talking about, they r trained within their own company and dont know that other bands exist and not all 4G r on the same band, same for 3G. So i suggest u sell ur phone and get a tmobile phone or switch to ATT. Next time when u buy a phone, insert ur Sim card in and test the network before u pay

The phone was NETWORK LOCKED when I bought it, so I guess I suppose I'm glad you we'rent with my when I bought it lol.
I'll take into mild consideration that a multitude of people may not be aware of alternate existing networks.
The T-Mobile phone I had before licked ****ing sac, my buddy has a Captivate that OVER-SHINED my Vibrant any day of the week - So No, I won't buy a phone from a company that's supposedly being bought out BY AT&T.
From previous quotes: It seems that we are implying that ONLY a T-MOBILE BRAND PHONE can access the 4Gish HSPA+ speeds that Simple Mobile network (that uses T-Mobile towers) and not an AT&T branded phone.
Yes, it's true....the above DOES in fact sound stupid when I put it on paper. AT&T and T-Mobile use the same towers and Simple Mobile/Metro PCS (some other un-explained networks) use the SAME towers.
So how is it, according to posters: That replacing AT&T phone with T-Mobile garbage will allow me to acquire the DL speeds that reference HSPA+/4G speeds. AND NOT, under any circumstances is it possible for an AT&T phone that uses the same towers to get the same outcome?
OK, the last part really does sound stupid, I feel like I'm arguing with a mockingbird. Anyone else have any further to offer?

Actually I re-read this statement. AT&T don't use the same bands, something about T-Mobile uses 850 and AT&T uses 1700.
Would changing the band selection make a difference? How to if possible?

I think u can only change the APN, not the band, the band is hardware, not software. I had the same problem trying to use my Desire HD on tmobile and couldnt get anything more than edge. I did also ask questions here and all i got is the answer i told u. So sell ur phone asap, dont wait until its price drops more

Will straight talk sim work on not "straight talk phones"?
Which cheapest phone of straight talk I have to buy to get their SIM-card?
I know they selling GSM and CDMA phones and don't want to buy wrong one.

Flat Out answer only the 2G or EDGE bands in the phone are compatible with ATT networks the other bands are different so if you want bettter speeds get att or use wi-fi because edge is all you will ever get no matter what you do to the APN

like on the previous post mentioned, i think most of the att phones doesn't have the radio that is capable of receiving the 3g/4g frequencies tmobile use. i could be wrong, but i think is a hardware problem rather than a setting you can change.

Simple mobile is Tmobile, 3g may never work.
Strait talk is a variety of carriers, depends on,the specific phone. The only known phones that work from the att network and have a Sim that works in other phones are the expensive Nokia smart phones. But those also have a Tmobile variant, I don't know how to tell the difference without looking at the Sim.
There is also consumer cellular, apparently that,is att but I don't know if it's full talk text and Web or how it's billed.

Consumer Cellular is VERY "no-frills" - it's only for VERY light users.
There is no AT&T phone that I know of that supports the 1700 MHz band required for T-Mobile 3G.
The only phone I know of that has pentaband HSPA+ (works on both AT&T and T-Mobile) is the Galaxy Nexus.

When I programmed my HTC Evo 3D i saw various optinos for cdma/eg/4g in CDMA Workshop & QPST Service Programming, what I saw was diferent types of bands and freqz, you might wana check out a phone's specs of tmobile and then check if those specs (frqz & bands) match with the one set on your device...
For example
The Vocoder settings
band prefferences :
band class 0/1/2/3/4/5/ sys a/b/
GSM DSC 1800
GSM extended 900
Etc etc.... check with the device's password on it's profiles and realms (settings I can view on my evo using ##data# )

I can confirm that the issue is with the phones. I just ran a test using my simple mobile card on an AT&T Infuse vs Tmobile Vibrant 4G.
AT&T Infuse
Edge connection with 50kps max
Tmobile Vibrant 4G
3G connection with 240kps max
I will be going to staright talk at the end on this billing cycle.

HTC Thunderbolt on AT&T - LTE Only ?

Hey,
First of all let me say I know there are other posts concerning HTC Thunderbolt on AT&T, but mine is a little different.
My wife has an HTC Thunderbolt, loves it and wants to keep it. But we have moved to a new place a few months ago, and since then we don't get any verizon reception in our place! But AT&T works, and has data!
I have a Galaxy S, and will switch it soon to take another phone with another carrier. My wife has the HTC Thunderbolt, and doesn't want to switch phone and pay a new device.
Now one small detail about my wife, she is mainly interested in data only. If there is a way for her to get internet only on her phone, she would be happy. (She sends texts via Google Voice, and can place calls on her PC).
Do you guys know if it is possible to somehow get a tablet SIM card from AT&T, put the SIM card in the SIM card slot of HTC Thunderbolt, and get internet only on the Thunderbolt ? I know the phone is CDMA, but she doesn't really need the phone or text message capability. She basically just wants a small tablet. I'm mostly saying that because I know AT&T is LTE also, and that it might work ?
Otherwise did someone succeed into changing careers with something else ? Virgin Mobile ? Cricket ? etc...
Thank you

The tbolt is CDMA but has a sim slot?
Will att sell you hotspot card and she could WiFi her tbolt to it?
via xda premium on my AOKP'd Evo LTE

tbolt does have a sim slot. It is a hybrid phone like all 4G Verizon phones. Basically the phone uses CDMA for 3G and phone. And uses the Sim card for LTE.
We could just buy a hotspot yes, but that's an extra device to carry which she doesn't want to do.

AT&T and Verizon use different LTE bands I believe...though they are both in the 700 mhz range I doubt the thunderbolt has the radio bits to get on AT&T bands, as it predates the existence of AT&T's LTE and I don't think hardly any devices even now have that capability. I can't see the harm in throwing in a sim to see what happens, of course.

The thunderbolt lte radio doesn't operate at the same frequencies necessary to work on at&t. It was made that way so that you can't switch the phone to other providers. It will work on other cdma type networks but GSM providers like at&t are a no go.
Sent from my Thunderbolt using Tapatalk 2

I'd like to add that the Verizon SIM is not your ordinary typical SIM. It's a RUIM card. I believe the thunderbolt can only accept these kind of cards as well. But in either case, Verizon’s LTE network operates in the upper half of the 700 Mhz range (746-787 Mhz), while AT&T’s operates on the lower half (704-746).

Way easier just to get an AT&T phone. You could probably trade one outright for an Inspire 4G. They're both worth about $100 in great condition.

That would be easier, but..... I too have wondered about what other hidden features are in the Tbolt.
Example: (It's rumored when official ICS is released for the Tbolt, international roaming will be activated or allowed.)

It's also rumored that ICS will actually be released...

Its rumored that ics will make my thunderbolt so much better it can fly.

Straight talk

Hey guys I have a question about straight talk service.my question is what is the best option between simple mobile vs straight talk.the thing is where I live T-Mobile service is only edge service so I called straight talk customer service and they told me that they run on T-Mobile and at&t so can I use at&t service on my Samsung galaxy s 4g.(at&t is the best service here now does any one here have straight talk on there phone here that can give me some advice..side note my phone is unlocked
Sent from my SGH-T959V using Tapatalk 2

I currently am not on either one of those services. However if I understand correctly about the two services I believes Simple Mobile is the better service when it comes to data usage, however though according to research the two are very similar when it comes to coverage(they both use basically the same towers) the main differences would be data caps. Look into the data caps of both plans, but if what you are saying is true about T-Mobile having only Edge then that shouldn't really matter, go with the one that has the better speed, because if you only get Edge you'll never even get close to the data cap anyways.
I've even read things that say Straight Talk now owns Simple Mobile. How true that is I don't really know, do some research for yourself and make the best decision from your budget and your area, even if I had one of those plans my experience would most likely be very different than any experiences you will have because of the areas we live in. Try talking to people in your area that have one of the two, they would know a lot more about the service, speed, and coverage than anyone that doesn't live near you.
That's just my advice...

Check you: T-mobile Unlimited Nationwide 4G

just one thing you need to know. when if you go to att, the thing is you might not even get 3/4g but only edge because of the difference on frequency/broadband att and tmobile uses. i don't know about straight talk because never use it nor research what frequency/broadband it uses

The biggest issue is Straight Talk has a invisible DAILY data cap. And they dont just shut off the data they turn off the service completely. Ive been told to order the T-Mo sim from them not the att so you dont hit the daily cap.

I would use a data monitor for a couple weeks get a idea of how much data you use per day. Then decide if it is worth having to ***** at ST to get your account turned back on if you go over.

The SGS4G has a 1900 MHz UMTS modem, so you should be able to get at least 3G from the AT&T network (unless you live in one of their 850 MHz areas).

Clearly state that our device only get 3/4g from 1700/2100MHz and others are Edge/2g

I just switched from T-mobile to Straight talk due to the same reason as stated in the OP. The T-mobile coverage was bad in my office building and AT&T penetration in buildings is always claimed to be better. I unlocked my Galaxy S 4g using the helpful posts from here and ordered the Straight talk AT&T card. I can confirm that I do see 3G showing on my phone and the speed was great when it was 3G. But, its not always 3G, I do get in the Edge areas too often too. I am very happy because my voice coverage has improved leaps and bounds after switching.
I have read about the scary part where Straight talk cancels service if we go over some hidden limits. So to be safe, I ported my number over to Google voice and use that to make a call. This way, I can switch between phone providers easily without any porting issues. But, not sure if Google voice will remain free after the end of the year.

Samsung doesn't advertise the 1900 MHz UMTS band for the phone, but it's there. I often swap out the SIM on my phone with my work iPhone, and the 3G works just fine.

[Q] one x prepaid?

Ok I have looked everywhere for a solid answer on this.
I actually bought this unlocked att branded one x for use with T-Mobile prepaid. I however didn't know that my data (even with adjusted apnpsettings) only got edge speeds. So I'm trying to find.prepaid alternatives .. I was told by att that gophone doesn't work with their 65$ 1gb data plan because it's a 4g phone. Is this correct? Also I've looked into straight talk however with Sims costing 50-90 dollars and uncertainty idk . Any reliable information on what I can do with prepaid with this phone AND have 3g/4g possibility please let me know ASAP.. thanks everyone

What city are you in? The website Airportal.de shows where T-mobile is activating 3g for non T-mobile phones.

Not sure, but I think they might mean you won't get LTE, but you may still get HSPA+. Others have have tried this might be able to chime in with more certain information.

I unlocked my AT&T HTC One X and have used it on T-mobiles prepaid for a few months now. I generally only get EDGE speeds, unless I'm in a large city. Thought before I did it I would have at least 3g. I'm also looking for other options. Good luck

4G phones are locked out of AT&T prepaid plans, so you can't use it on AT&T.
This site has a nice breakdown of prepaid carriers.

Definetly check out this website. If you see any pins in your area for 3G (HSPA+) maybe hold out until they bring more towers online. In my area they are adding a few miles of coverage per day.

4G phones are too powerful for AT&T prepaid.

Check the site linked up above and see how close they are to building out their network near you.

What does that mean exactly, that the phone simply won't work at all (even for voice and EDGE)? Or that it will only work on voice and EDGE? Or it will work on 3G HSPA, but not 4G HSPA+?

My understanding is that ATT checks the IMEI of the phone accessing data and if it is a phone with 4G capability it blocks it completely. No EDGE, no 3G, nothing, no data access. You may be able to skirt by for a while until they track you down and cut you off, but it is only a matter of time until you are cut off. Voice should work.

I'm using this one x prepaid and get full blown 3g on straight talk no LTE service so how can that be true?

I believe he's referring to AT&T's own prepaid plans, not Staight Talk's plans

So beat me if needed. I have a new att one x coming today. If i get it unlocked,and use a straight talk sim that is a tmobile sim, should i not get the same speeds as a $30 tmobile 5gig plan? I live in mpls and right now get great speed on my n4 with a $30 plan. Thanks b4 and after.

Short answer is probably not sorry
The n4 is pentaband and gets all of tmobiles bands. The att one x might get 3g on T-Mobile depending on the refarming in your area. Chances are it won't be as strong or consistent as the n4

Exactly what I tried and depending on ur area u may get 3g. I ended up with only edge speeds.

If youre on straight talk just buy a att SIM. Att has just as good of coverage in Minneapolis.

Straight Talk stopped offering new AT&T SIM cards a month or two ago. The only option for new customers is T-Mobile SIM cards

Why would they do that? I guess I got mine in time. The one xl would be useless in my opinion stuck on edge speed
