Hi guys,
I have a strange problem, I guess.
I bought my HTC Desire 610 on amazon. It is AT&T.
I use it in a different country with GSM sim. Everything seems to work fine. I am connected to 4G network if I am in 4G coverage zone. But when I dont, it won't switch to 3G, it just goes offline.
long story short: 4G seems to work, but 3G don't.
network mode is set to WCDMA/LTE Auto.
could anyone help?
I think this is something to do with the Rom, if you were to install the cyanogen mod or the slimkat Rom, 3g works just fine in both, idk why though

I Installed GSM signal monitoring application. As it turns out the phone only receives HSPA+ (3G) signal, but somehow thinks that it is 4G. Because 4G is displayed on top of screen. that is why I thought it was working on 4G network. but now I guess it works on 3G but thinks that it's 4G
now I want to enable 4G but have no idea how

Depending on what country you are in 4g probably won't work with an at&t phone as the different variants have different 4g bands unlocked in the radio firmware and probably antennas. See the following extract from desire 610 network specs. US 4g bands are quit different from those available in most regions.

Its hard to say for sure. Try a ROM from the region your in or cm11 which is for all regions. This probably won't work but is worth a try. Otherwise to that you would have to go s_off with sunshine (costs $25) and flash changes to radio firmware( either someone's dump from a phone in the region your in) or modifying it (google "XDA qcom unlock radio bands) but either way it's very risky unless you really know what you doing you can easily end up with an expensive brick and it still depends on whether you phone is equipped with a suitable anttena for the frequency the band your carrier is using.

Hello All,
I am on tmobile and had samsung galaxy s before i got SGS2 from at&t (my wife upgraded). i unlocked/rooted the phone after reading through the posts and it worked like a charm!
My concern right now is that I am always on edge data network with tmobile. can anyone help me on this. Tethering is also not much of use when i am on the slowest connection. Please help.
Can't do much about it since AT&T version doesn't support the 3g/4g band for T-mobile.
At&t gs2 doesn't support t-mobile frequency for 3 g.

No only AT&T.
My guess is that international version supports all the bands not the carrier branded sgII
^Even international version doesn't support T-Mobile 3g/4g (HSPA+) network.. Not many phones support their network. Or maybe it will.. but not everywhere

The AWS (1700) bands are supported only by a handful of carriers. It doesn't exist at all in Europe and Asia. There's little reason for manufacturers to include it on their global phones as so few people use it. It's the reason the T-Mobile SGS2 has a Qualcomm chip instead of Exynos like the rest of them. After the merger, it won't even exist in the U.S. any longer as AT&T plans on using it (1700) for LTE. If you want versatility and the ability to use unlocked phones, change to AT&T.

In order to get T-mo 3G, a phone must support HSPA on 1700MHz AWS band, not 850MHz. As such, only phones from T-Mo or some Candadian carrier support 1700 band. Rest of the world use 900/2100 for 3G and AT&T uses 850/1900 for 3G/4G.
You are never going to get 3G on T-Mo on any phones from AT&T. Period. Give it up.

TMobile uses 1700 up, 2100 down. If the handset doesn't support 1700, you are out of luck.
Correct. Many phones support the 2100 MHz International band.
T-Mobile's network is weird though, and uses both 1700 and 2100 MHz at the same time.
My guess is that UMTS1700 support and not 42 Mbps HSPA+ is why the T-Mobile variant of the GS2 is such an oddball phone.
NO AT&T phone and only a small handful of international phones support T-Mobile's 1700 MHz band.
Similarly, only one or two T-Mobile phones (The Vibrant being one of them) support any of AT&T's 3G bands, but none support all of AT&T's 3G bands to my knowledge.
The interesting thing about this entire thing is that if you go into the modem band selection it lists 5 different wcdma bands including the aws 1700. I enabled those bands and tried using a tmo sim but alas it still only worked on edge. It may have just been there cosmetically rather then actually supporting aws bands. use dialer code *#2263# to access the band selection menu. Maybe there is a way to get it to work.

I agree with you and have tried exactly what you did (along with other bands) but still not working.

Typically, the s/w supports multiple versions of h/w. Just because an option's in the menu doesn't mean the h/w's available to support it. The same thing happened with the T-Mobile G2X. It was supposed to be quad-band, the option was in the ROM, but the radio wasn't there to support all the bands.
I have the HTC Radar 4G on T-Mobile. Once I unlock it and use it on At&T, it will definitely do calls, but will it pick up 3G or 4G on the AT&T network? I asked HTC and they were unsure. Thanks!
Do a search in this forum to find your answer.
Sent from my Titan using XDA Windows Phone 7 App
AT&T uses 850 MHz / 1900 MHz for GSM/GPRS/EDGE and the same two frequencies (850 / 1900) for UMTS/HSPA (their 3G/4G service).
T-Mobile uses the same frequencies (850 / 1900) for GSM/GPRS/EDGE, but uses 2100 MHz and 1700 MHz for UMTS/HSPA/AWS (their 3G / 4G network).
If you want to know what phones will work where, compare the frequencies they receive with those of the carrier you want to use.
In the case of the Radar, it uses the following frequencies
GSM/GPRS/EDGE: 850 MHz; 900 MHz; 1800 MHz; 1900 MHz
UMTS/HSPA: 1700 MHz; 2100 MHz
So, for GSM phone calls and data you have a match with AT&T (and, of course with T-Mobile). 3G / 4G is a different story. The Radar has the T-Mobile 3G/4g bands, but not the bands for high-speed data on AT&T.
So, if you are happy just making phone calls and using EDGE data, then you can use the phone on AT&T. If you want 3G /4G as well you have to stick with T-Mobile.
bleh bleh +10
I finally was able to get the h2O SIM card (AT&T service) and surprisingly it picks up 3G! I definitely notice the difference from when it goes from 2G up to the 3G speeds
http://www.htc.com/us/products/radar4g-tmobile?view=1-1&sort=0#tech-specs
Apparently. It says it does 2100/1900/1700/850
*T-Mobile only uses 1700/1900 bands. source
Interesting! I took my specs from the T-Mobile page which omits the UMTS 850/1900 band. Thanks for the correction.
The box clearly states GSM 850/900/1900/2100 AND HSPA/UMTS: 1700/1900/2100
AWS 1700 = T-Mobile, Wind, Mobilicity
UMTS 1900 = AT&T (although they use 850 extensively too), Rogers, Telus, etc
UMTS 2100 = Asia/Europe
My Radar picks up AT&T 3G. Not sure if UMTS 1900 band will be omnipresent on AT&T as a lot have been extended with HSPA 850 as well.
So, whereever you find UMTS 1900, you'll definitely catch AT&T 3G
Hope this helps.

Hi,
All Guys in Singapore specially pay heed
I bought this lovely phone to be able to enjoy quad core for one and LTE data access. It seems that when I try to connect to the 4G LTE on Starhub (in Singapore), I only get 4G, not the LTE speeds.
Please correct me if I am wrong, that the e970 has 1700 and 2100 band for the LTE, while Singapore only has 1800 and 2600 bands available.
Is there any possibility of enabling 1800 and 2600 bands?
The local variant is the E975, can I flash the stock e975 firmware to the e970 without adverse effects?

You can use 2G, not sure what the 3g band is in Singapore.
Sent from my Optimus G
My quick search shows Singapore uses 2100 for 3g, so the phone will support it. However, you cannot add or enable new frequencies. The hardware does not support them unfortunately. Your local LTE is not compatible with the E970

You can use 3G/HSPA+, I was there last week and I was getting 5-6 Mbps using SingTel prepaid.
EDIT- No LTE, sadly. But 3G was enough for anything I'd do on my phone.

HI,
yes the HSPAP works quite well. Im on the StarHub network, I also get a decent data rate. But LTE is LTE, it would have been nice to be able to coax the E970 somehow into those bands.

Bump. I have the same question.
GSM Arena says this about the device:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 800 / 850 / 900 / 1800 / 1900 / 2100 / 2600
If what wikipedia says, AT&T uses the following frequencies:
2G: 850 / 1900.
3G: 850 / 1900.
4G: 700 block B (main frequency) / 1700 AWS / 1900 / 2300.
So, if I read correctly, you can use the international Alpha for 2&3G, but for LTE, you are covered only by one LTE band, 1900, and this being not a main frequency, won't have good coverage everywhere, I think.

Yes. If it was me to make the decision, I'd want my phone with an unlocked bootloader, HSPA+ is good enough speed for me.
Though, practically, I've never tested LTE in my life, until recently we didn't have any 4G networks.

I bought an unlocked international/Euro Galaxy Alpha SM-G850F at the London Samsung store... Installed my USA ATT SIM and have no prob w. calls or H or H+ data but can NOT get LTE band in the USA on either ATT or TMO even though the device seems to have the right bands for ATT or TMO LTE. On advice from an ATT Wireless store manager, I updated my APN settings to match ATT setup but still did not get LTE. FYI my H+ is quite fast for most purposes but I want LTE. Hope that answers your question.... Mine is how can I get LTE???

I am trying to solve this also.
I think that the Euro Version with the Exynos does not have the proper LTE Bands for North America LTE.
But the Qualcomm version does, though not sure about
TMobile.
I am looking at this from Canada GSM for $ 549. Factory Unlocked with following Bands:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G & LTE 2100, 1900, 1800, 1700, 2600, 700, 850
Obviously for AT&T you just buy theirs.
I have read that the EXYNOS versions do not function in North America on LTE.
With all phones it seems that you must be very very
Specific about Model Numbers including Suffixes etc.
Especially SAMSUNG loves to make 24 versions of ALPHA, 50 versions of S4 etc.
Frequency Bands are a real WTF for amateurs like me:
For example are there TWO DIFFERENT 1700 bands, one for4G LTE and one for 3G , HSPA + or are they the SAME BAND with dual usage ?
In example ABOVE the Alpha Factory Unlocked Canada GSM @$ 549.
IF used for TMobile the LTE Bands look fine, but the 3G
1700 Band is not there. Will 3G merely use the 1700 LTE
band or does the SOC ( QUALCOMM) need to have
allocated the 1700 band for dual usage LTE and.3G
?

the supposed bands are similar to what is on the Honor8Pro. in which case, 2G and 3G should be fine but 4G might not be possible. it also depends on which carrier you use in US later on -- probably your telco choice would be the non CDMA ones -- AT&T and TMo.
anyway, see these two threads:

As long as I will be able to use 3g is ok for me.
I am. Going to read those links you posted. Thanks!!
