I know how At&t are gonna have HSPA+ 4g, I'm confused about the new devices they're gonna have that support HSPA+. Are they going to be able to connect to HSPA+ on T-Mobile's network.
So for example, I buy an unlocked HSPA+ tablet from AT&T, straight from their store. Is it going to be able to use T-Mobile's HSPA+ network if I put a T-Mobile SIM card inside?
Also, one last question, if I use T-Mobile's SIM card, do I have to do some special stuff to get it to work on their cell network? Like how you have to unlock an iPhone for it to work on T-Mobile?
Thanks

Hello,
Unfortunately you will not be able to use HSPA+. HSPA+ is just an extension/revision of the current 3G. Effectively it is also called 3.5G/3.75G in some reports. They use the same 3G band of each respective company. The At&t tablet would work on 850/1900 band and T-mobile will work on their AWS (1700) band. So if you bought an At&t tablet, you may need to get it unlocked, not sure if they lock the sim on tablets. At best you would get Edge service with a T-mobile sim.
thanks man, argg
do you think it's worth it to change to at&t because I just heard of the Motorola Atrix and it sound PRETTY BAD ASS!
I don't know since people I know are always angry at AT&T for their service either..

NP. I have had every major carrier offered in the US. I have had at&t, t-mobile, and sprint within the last year. I had verizon a while ago and dropped them because they could never get my bill right. Honestly, the service is about the same. The question is how is the service in your area. I mainly stay in my area about 90-98% of the time. I live in a major city so all carries have great service. But I have stayed with At&t for the last few years. Every time I go to another carrier I kept my at&t service, go figure. So I would just look at coverage to where you travel the most and go with a carrier that will give you the best coverage for the best price. Do i prefer a carrier over another, yeah. I like GSM carriers better because I do like to surf and talk at the same time. Sprint can do this if your in a 4G coverage area and have a 4G phone. Verizon is a no go with this feature until they release their LTE phones. But At&t has a better coverage footprint than T-mobile that is why I stick with them. Hope it helps.
Wondering a bit about this too.
I have service through Bendbroadband using a HSPA+ SIM with USB modem Dongle by bandluxe. The service is stellar on the speed, but I can't use the dongle with everything (iPad), so looking for alternate routes before i decide to move to a different provider.
I noticed that the CTO of the company said in a comment regarding their service that any unlocked UE that supports HSPA/HSPA+ in the AWS band could be used, but also had an unclear reponse on cell phones with HSPA+.
I have a Huawei Comet (unlocked), it lists the same AWS Bands compatible, but says HSDPA (which I thought HSDPA + HSUPA = HSPA+ but at higher speeds, correct me if I am wrong), and has hotspot tether that works with tmobile web service no problem.
I plugged the SIM in, and it updates the bar with BendBroadband but I get no data. (might need to provide the IMEI or something)..
Curious if you think it should work, before i go knocking on their doors.
Some other specs:
the mytouch 4g (HSPA+) lists the bands as:850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band IV (1700/2100)
The comet is listed as: 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (1700/2100)
I am fairly sure the comet is HSPA+ but not advertised that way.
According to comments on the site, Bendbroadband technicians do not actually support moving of the SIMs. Bummer.. trying to keep my business local.. Bumping and moving to Tmobile once the month is up.
I am currently in Japan with my htc inspire and I am not getting any signal at all. I tried resetting and going into the settings menu to change the "network operator" but its greyed out.
does anyone know what I am doing wrong? I desperately need it to work here and I have the international plan activated on my account.

Well in Japan you wont get 3g due to Japan using 2100mhz and The Inspire does not have that freq built in. You should get a call signal. Make sure you enable international roaming on your account. Or if your phone is unlocked buy a local sim card and pop it in.
I enabled international roaming on my account and have the $6 plan added for cheaper international roaming service.
I don't need 3g, just a phone signal to make calls and receive texts. but all I get is a "x |on top.
I have travelled to countless countries with my other unlocked phones and have never had a problem with my phone not picking up a signal.
is it possible that because I changed to a 3g sim card, it doesn't work abroad?
japan does not have gsm EDGE coverage i dont believe. they do have 3G HSDPA, but on 2100mHz, which the inspire does not have. so you are kinda out of luck i'm afraid.
Verified with AT&T's tool here
http://www.wireless.att.com/travelguide/coverage/roaming/step1.jsp
The Inspire doesn't get voice or data in Japan
Had the same problem in Korea last week - sucked big time. How can they call it a world phone and leave out 2100!!!!
That is absolutely terrible and false advertising since Japan and Korea re left out which are huge territories. I also have an unlocked samsung vibrant that I need to charge to see if it works.
Does anyone know if the vibrant has the right frequencies for Japan?

According to the same tool I previously posted, the Captivate will work in Japan and South Korea
Edit: Oh, Vibrant... hold on
Don't know about the Vibrant, does it have the 2100 frequency? If so, then probably yes
Yeah I still can't believe this phone left out the 2100 frequency. I posted about this a few weeks ago and still can't believe I didn't notice that it didn't have the 2100 when I bought it, as I travel to Japan quite often.
I don't like the Atrix and the Infuse 4G isn't out yet so I'm just waiting it out until some better phones come out and will just use a older phone in the interim. Those both support 2100 apparently. Kind of ridiculous that HTC left it out of this phone.
Just did a quick search and it looks like the Vibrant does have 2100 UMTS support.
Sprint CDMA works in Tokyo (and possibly Verizon). Not sure what carrier it uses but it does work for voice only. Probably not much help though.
Ok, so I've searched all over and haven't had much luck. I have no experience with cdma phones, as t mobile is all I've ever had.
I was given a new US Cellular HTC Hero s. I opened it up and saw the sim slot and though, sweet I can replace my sensation with it (I smashed the screen pretty bad). Well, that was a no go, as the phone is cdma. Looking online though, I see it can run in gsm (options global mode, cdma mode, gsm / umts mode. I unlocked the bootloader using the htc site (not sure it matters) and popped in my sim card again, and tried both global and gsm mode, though neither got signal or would dial out. (under networks, it had the tmo apn info.)
So, is the GSM mode offered on this phone only for non US bands? Would a custom rom (now or down the road) allow it to work on tmo? I read something about the HTC Merge and someone being able to switch out the modem in the rom that allowed it to work in the US, but that is well beyond me. I can follow instructions, work ADB and flash roms.. but thats about it.
Is it possible, or will it soon be, to have this phone work on GSM or am I just stuck trying to sell it as a us cellular phone (or perhaps another cdma carrier.. like I said, I don't know anything about cdma)
As a Canadian I'm not sure about who owns US cellular or if they are their own company but I'm guessing they work like Verizon world phones. They have sim card slots but will work only outside of the US. If those verizon phones are used within the States, they will only pick up Verizon's frequency, as opposed to T-Mobile or AT&T where you can unlock them and use them with any GSM carrier within the States. But yeah, you can unlock it and it will work with any GSM carrier outside the States but within the States I think it will only work under US Cellular CDMA network...please correct me if I'm wrong.
That's right, u.s. cdma "world phones" have gsm radios but are locked down from connecting to gsm networks in the u.s. This is not just the normal sim lock found on gsm phones but they are hard coded to ignore u.s. gsm networks.
Some have been unlocked to work on any network through various methods including flashing a modem from a non-us varient of the same phone and other hacks. I can't comment specifically on this phone however.
Sent from my SPH-D700 using XDA App
Well, that points me in the right direction, and confirms what I read about swapping modems (on the other phone mentioned).
So basically it's software telling it not use a certain frequency, and not that the phone itself is incapable of picking it up (had my doubts about that)
Pretty shady the way phone companies are allowed to operate (don't get me started on my unlimited internet in my contract [pre data caps in tmo]. "Hey! check it out, this phone uses data 5 times faster than your old one, oh, and you get half as much too) sorry, end of rant.
I'll keep searching, and post if I find something..
On a side note, can cdma phones be flashed to another cdma carrier like verizon or sprint, or is it the same deal, coded to only use a certain frequency range?
only thing I've heard of is flashing sprint and verizon phones to cricket, metro pcs and boost.
Got my FIDO Razr HD. Rogers SIM = all is good. AT&T sim = asks for unlock code, which i buy online.
After entering code, phone appears to do a factory reset. During the reboot, a box pops up:
"SIM not allowed MM #3"
Now the phone permits "Emergency Calls Only" with the AT&T sim. Rogers SIM = still good.
When I put AT&T sim into my other phone (HTC desire) it works fine on roaming (rogers network). So I know sim + signal is fine.
Don't understand this error message.
Did I mess up the unlock?
advice appreciated, thanks.
Do you have another Canadian SIM you can try? Bell/Telus etc?

Thanks for the replies everyone. to answer the questions:

2) they were regular sims that were cut down.
3) haven't had a chance to visit USA since posting topic- but when i do, i will test both cards and also visit an AT&T shop to bug them about it.
Is sim corrupted? I don't think so because it works fine in HTC desire. But I guess trying a new one will prove or disprove.

I am using this phone with at&t with no problems, I took my sim out from my iphone 5 and used a adapter to go to micro sim and it works fine, no issues.
I'm receiving a Fido RAZR HD to be used with AT&T this afternoon, I'll let you guys know if there are any issues.
OOI, is AT&T seen as a much better GSM network than T-Mobile in the US?
I was looking at the T-Mo USA site, and there are some amazing "Monthly4G" SIM only plans (e.g. $30/month for 100 minutes, unlimited texts and 5GB of HSPA data).
This seems much better value than AT&T, Verizon and even Sprint! But is their network sketchy compared to the others?

AT&T offers the second largest network coverage behind Verizon. They are also one of the two GSM carriers in the United States, and tend to be more popular with mobile phone enthusiasts because their UMTS bands are more common and used with other regions such as Canada or Australia. T-Mobile does indeed offer excellent value, but they use mainly AWS band in addition to PCS band in selected regions, thus making them the lesser choice for using unlocked phones from outside the country.
Hey,
Just looking on wiki:
http://en.wikipedia.org/wiki/T-Mobile_USA#Radio_frequency_spectrum_chart
http://en.wikipedia.org/wiki/AT&T_Mobility#Radio_Frequency_Summary
It looks like T-Mo mainly use 1900 for 2G and 1700 for 3G, whereas AT&T use 850 and 1900 for both 2G/3G, right?
So if I bought a Canadian Razr HD XT925 and came to the US, would I be able to use T-Mo's 3G network? I am guessing no, since it does not support 3G on 1700MHz.
But then there is a note on that Wiki page saying that they now have a roaming agreement with AT&T after the failed acquisition. So if I forced the phone into "WCDMA only" mode from the test menu, would it then fall back onto the AT&T 3G network?
Sorry for taking the thread slightly off topic
Cheers,
Su

As you have read, T-Mobile did acquire PCS bands from the failed merger with AT&T, but these bands are not as utilized as their 850 MHz band so it's not as widely available as you may think. Some areas might be able to use the 1900 MHz band for T-Mobile 3G, but I would check with fellow T-Mobile users to confirm first before you dive in headfirst. I know that there are T-Mobile users in the Dallas-Fort Worth area that are getting 3G data connectivity with their unlocked AT&T iPhones.
Well T-Mo do daily plays for like 2 bucks right, so I can always try this out before committing to a contract
Do you think AT&T would be the better bet if I am bringing my own device from Europe?
The reason I ask is that I may be coming to a US college for a couple of years, so naturally, I'm planning ahead to see if my phone will work over there

If you're using a device from Europe or Asia, then yes, you have a much higher chance of being able to get 3G connectivity with AT&T. Off the top of my head, Nokia seems to be the only one that tries to actively keep AWS band in their radios.
Hmm, so I did a bit of research on GSM Arena. Seems the Nexus line of devices consistently support 1700MHz 3G (including the Nexus S which I currently have).
Guess who cancelled their Nexus 4 order last week, and opted for a Canadian RAZR HD instead...

Hi all,
With Verizon releasing officially, the update making its SGS3 Global ready atleast for voice as of now, a lot of discussion is happening right now about the Global capabilities.
FYI. I'm a good reader and explorer on hofo,androidforums and xda. So any guidance is highly appreciated
So here is my question.
I have a Verizon S GS3. It is brand new.
1. Can I use it with Straight Talk T-Mobile SIM ( T-Mobile has good coverage near my house ) after doing the rooting, unlocking, etc. etc all the technical stuff
2. If I unlock the phone, will it be truly global capable, I mean, can I use my S GS3 on any GSM Network in the World, even in the USA, with 3G Speeds? Did anyone use it in any Country with 4G LTE Speeds?
3. I know this is really a very very strange question. But after unlocking the S GS3, will it be working on the AT&T LTE Netowrk in the USA? My thinking is, if it working in the LTE Network in the USA, then it will work in other countries as well, where LTE Network is going to be available in the future. Sorry, I know this is a bit weird.
If You can please refer and threads or links, it is fine with me. I'm also looking and not depending only on the answers that I get from this thread. But looking for replies/guidance/links though.
Thank You.
hope this is the answers you are looking for

for Q1:yes you well be able to use any network... install any mod now most of them are already rooted and unlocked
for Q2:yes you can... all you need to ddo is to download a program called hiapn.. wipe the existing apn settings.. then auto detect and you are good to go 3g and hspa
Q3: yes it works thanks to the magic of hiapn software... but not many countrys use LTE .. usa canada japan and maybe few others
Verizon SGS3 on any GSM Carrier
Hi experts,
I have a small doubt here.
If the Verizon SGS3 can be used with any GSM Carrier around the world, then that means, the Verizon SGS3 can be used with AT&T or T-Mobile as well along with Verizon Network.
But the T-Mobile or AT&T Versions cannot be used on the Verizon's Network. Is that true?
I'm have got a traveling assignment coming up to Europe this Summer and I need to know what is the best possible solution out there before I leave.
Thank You.
Verizon's GS3 uses CDMA technology for the phone calling and data, as far as I know the SIM in the verizon version is only used for LTE.
From what I have read in forum posts, (this one in particular http://forum.xda-developers.com/showthread.php?t=2013647) if you pop in a SIM card, calling and texting should work. If you want data to work then you need to change some APNs around. Stock touchwiz does not allow this so you would need an app to do that. AOSP ROMs should have a way for you to edit APNs.
On the topic of getting 4G on any other network besides Verizon, that is fairly unlikely as they all use different technologies/ bands. Verizon has LTE, T-Mobile has HSPA+, not entirely sure what AT&T has but I think its also LTE.
This phone will take any SIM card cut to micro-size.
3G+ speeds depends on the frequency the carrier uses. The VZW GS3 uses the following radio frequencies after the JB update: GPRS/EDGE/GSM (850/900/1800/1900); HSPA/UMTS (2100) [I had to search high and low to find this for my trip to China]
Each LTE carrier uses different radio frequencies, and global countries also use LTE frequencies different than the US ones. 4G is a very varied standard at the moment.
If you want fast internet on a non VZW carrier, it better have HSPA+, otherwise you are on 3G at best.
Right now, the only truely global phone is the iPhone5 on VZW, which supports 5 different LTE frequencies. Sad but true.
The US based SG3's dont even have the FM radio that the international versions have

Yeah, my girlfriend has a verizon s3 and with straight talk she is only on edge it never changes. It makes the phone nearly useless. Ive tried to talk her into letting me flash and unlock it but she isnt real interested in it. I dont even know forsure if unlocking the bootloader downgrading to 4.1.1 and using the att sim unlock method would work but I would assume that flashing it would allow you to at least get 3-4g. not?
