[Q] HTC Desire Z A7275 (Bell Edition)

Hello, I have a HTC Desire Z A7275 (Bell Edition) phone, unlocked. The specifications are:
Network:
HSPA/WCDMA (850/1900 MHz)
GSM/GPRS/EDGE (850/900/1800/1900 MHz)
Here is my question:
I am planning to travel to UK & Europe next month. 1 Will this phone work on in UK & Europe? 2 Will this phone support 3G or 4G network in UK & Europe? 3 What are my options with phone in UK & Europe? What network will this phone support?
Thanks

My understanding is UK and Europe are on GSM 900/1800 MHz (voice, EDGE) and WCDMA 2100 MHz (3G). So you will have voice and EDGE service, but no 3G. But I have not personally been to Europe with this phone yet, so can't verify personally.

You will be able to use voice and 2G/EDGE data with any of the GSM carriers in Europe (just buy a local SIM and you should be good to go). Unfortunately, little or no 3G or 4G support (pretty sure that almost all countries in Europe support 2100 or 900 with the newer towers---850/1900 is limited to mainly the Americas and some parts of Australia, with a few other small regions here and there).

So what about this option: Sony Ericsson Xperia X10i
Specification: GSM/GPRS/EDGE 850-900-1800-1900
UMTS/HSPA BAND 1/4/8
will this work on 3G or 4G? All of this is so confusing to understand..Thank you

Every phone has two sets of bands.
GSM/GPRS (EDGE, 2G Bands)
UMTS/HSPA (3G Bands)
As posted earlier in the thread, most European countries use 2100mhz for 3G. So if you want a phone with 3G access, look for the 2100mhz band under the UMTS/HSPA portion of the specifications.
*Edit*: Not sure how reliant you will be on 3G but when I was in Europe last summer, data rates were not cheap. Also, Wifi hotspots were readily available in every major city that we traveled to and most times they were free to access. We purchased a cheap 'dumbphone' for emergency phone calls and used an Ipod Touch and my old Touch Pro to access the web over wifi.

Actually, 2100 MHz is Band 1 when talking about UMTS. 900 MHz is Band 8. So this phone will support 3G data in pretty much all of Europe.

[Q] International / Unlocked HTC 8 (M8x) - LTE bands?? Majorly confused

Hi - I got a killer deal on an international (Asian model) HTC One M8x on eBay so I jumped on it... After receiving it, I noticed LTE is not working with T Mobile. The phone supports LTE 700 / 900 / 1800 / 2100 / 2600... Before purchasing, I didn't notice AWS/Band 4 wasn't listed. Oh well, still a great device.
I did some research and saw that T-Mo just bought Verizon's 700mhz; but 'Block A' only..? my phone supports 700mhz, but I'm not sure which block it will work with.
I live in a pretty populated area in Southern California, so I would assume that this area will be covered when T-Mo rolls out 700mhz on their network around early 2015.
Will my phone work on Block A? What is the difference between blocks? I just recently learned about the different frequencies, and now I'm hearing 'block A, B, C,' etc.. I'm officially confused.
Anyone with extended knowledge of LTE - your responses are greatly appreciated.
thanks!!!

According to the following Wiki, the 700 MHz bands used in North America are also called Bands 12, 13, and 17. These seem to correspond with the blocks you mentioned (A, B, C) with "700 a" (presumably Block A) corresponding to Band 12.
http://en.wikipedia.org/wiki/List_of_LTE_networks
Of the countries and carriers in Europe, Middle East, and Asia (the "international" M8 is actually called the EMEA version) only Taiwan seems to use 700 MHz, and its Band 28. So presumably, this is the band that is supported by your version.
Not sure, but you might be out of luck (your phone supports Band 28, but T-Mobile bought Band 12?).
It is confusing, I agree. My main takeaway is that there sure a lot of different bands that make up 700 MHz!

Thanks for the info and the link!! After reading the wiki page I did some more Googling.. It seems as though the 700mhz is available through bands 12, 13, 14, 44, 17 and 28. It's crazy that my phone only supports one of them. Too bad I won't have LTE....HSPA+ is horribly slow where I live. (unless it's about 3am, then I get a few MB up and down)
I noticed you have AT&T...are you aware if this phone will pick up LTE on an AT&T gophone? I will consider their $60/month prepaid if it will.
Or maybe another GSM carrier that my phone is compatible with? I would really hate to leave T-Mo but I miss LTE.
thanks again for your help!

T-mobile's AWS platform is mostly going to be a 1900 and 1700 setup if i remember correctly. they have purchased the 700mhz spectrum from verizon but no one is really using it yet. Only Verizon has even started to populate that spectrum with their new X-LTE which no one can really take advantage of. and really the HSDPA isnt that bad. i mean i have a tmobile M8 and i get LTE like 70% of the time but the rest of the time i'm on HSPAP and its fine i get like anywhere between 5-10mbps...
http://en.wikipedia.org/wiki/T-Mobile_US
you can look further down the page it shows you every band that they use or own.

Its not really that crazy. When they say "700 Mhz" I think what they really mean is that the actually frequencies used are somewhere around 700-799 MHz. And this can be divided up to many different distinct "bands". If you refer to the Wiki page I linked, you will see in the notes under the North America section, for example:
700 Block B
(↓) 734 – 740 MHz / (↑) 704 – 710 MHz
So the MHz number can be misleading; and its really the Band (12, 13, etc.) that you need to pay attention to. Or both the Band/block and MHz in conjunction really, as its often the MHz that is listed.

Don't think it work on AT&T's LTE network. AT&T uses Bands 4 and 17 for LTE. None of these are supported on the EMEA version based on what we've discussed.
Buying phones from 3rd party sources can be very tricky. US carriers in particular use very particular and often proprietary bands. This was true with 3G, and seems to be even more so with LTE. The bands used by even foreign markets has become increasingly less standardized with LTE (there was a good amount of standardization in foreign regions with 2G and 3G). One has to be very careful and resource thoroughly before buying a phone from any source aside from your carrier.

hello , iam going to the USA with the same model m8x to t-mobile in Washington dc ,so basically iam in the same position as you , did u find any new solution to the LTE problem ? if not ,does only hspa+ working ? if so i have seen some good speeds with t-mobile hspa+ ( 15mb dowload ) . does flashing these (http://forum.xda-developers.com/showthread.php?t=2736921) helps ? please respond

T-Mobile bands...

I'm VERY concerned about buying this phone now. T-Mobile have only listed LTE bands 4 & 17 on their site.
International
Quad Band GSM; LTE: 4, 17; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850)
What in the eff?

Des just answererd this question on Twitter: https://twitter.com/askdes/status/581568102015569920
It has:
GSM - 850/900/1800/1900
UMTS - B1/B2/B4/B5
LTE - B2/B4/B12/B17 with CA + B3/B7 roaming
This is the perfect T-Mobile phone.

So the T-Mobile version does not have 1700, and is therefore identical to the other models? Do we know if it includes wifi-calling, or if we would be able to flash the T-Mobile ROM onto the unlocked dev version?

It does have 1700! That's Band 4, and for both LTE and HSPA.
The T-Mobile version also supports WiFi calling and texting. I have no idea if the T-Mobile firmware can be flashed to the unlocked version, but I don't see why it wouldn't be feasible.

T-Mobile (Des) confirmed: 2, 3, 4, 7, 12, and 17
AT&T lists: 2, 3, 4, 5, 7, 12, 17, and 29 (adds +5 and +29)
HTC Dev & Unlocked versions (per HTC on Twitter): 2, 3, 4, 5, 7, 12, 13, 17, 29, 30 (adds +5, +13, +29, +30)
Maybe the T-Mo phone supports more that could be unlocked, who knows. The extra bands aren't useful to me.

Sorry, but I just want to clarify.
Do all versions of this phone support BAND IV UMTS or not?

HTC has done this on the past couple of phones. Only the T-Mobile phone will do their specific bands (HSPA+). On past models I don't recall anyone getting the ATT/DEV models to work with those T-Mobile bands. I don't believe we ever found out why. Some speculated it was due to cost to license all the bands, or that it is actually different hardware. The M7 and M8 were both like that.
If you are on T-Mobile, I'd get the model specifically for them.

Oh yeah I remember my Dev version being like that. Fortunately, I live in an area that has been upgraded to mostly lte. This was actually beneficial for me and maybe others in the same situation because it actually saves battery life when the phone isn't constantly switching between edge, 3g/+, and lte. I'm sure many others have been in an area that's barely out of lte but still within h+ range and it's still slow as edge or even slower.

Yes, it is OK if you live in a major area that has lots of LTE. Here just north of LA, I get into the other bands pretty frequently.

I am not sure this was answered? Do all versions of the HTC one m 9 support band 4 UMTS? Many ATT carrier unlocked models are for sale and no one seems to know if they will pick up the UMTS 1700 band 4 on T- Mo?

They will not pick up the T-Mobile specific bands, which use 1900/2100 for 41bps speed. They will work with the T-Mobile LTE band.

Wow, still a mystery. I have the AT&T SIM Unlocked One M9 and I have a TMobile prepaid SIM and get Edge, 3G, 4G, LTE Band 2,4,12...I cannot find an app that shows the actual WCDMA (4G) Bands ? But, it notates 42 MBPS when it says HSPA+ 4G using Network Signal Info-Pro App..and also shows 384 Kbps when it says 3G....
So, seems Des is correct unless the Network Signal Info Pro app is wrong?

I turned off everything except WCDMA, and this is what I get being reported by LTE Discovery. HSPA+ @ -113. I have a ATT unlocked M9. I do have the T-Mobile 2.11.531.19 firmware installed as well as the T-Mobile rom.
Using XDA to unleash the power of Android on my HTC One M9

Thanks but as I mentioned I cannot find an App that shows the WCDMA Bands to confirm. As you can see even LTE Discovery says N/A for DL and UL Freq...when on WCDMA...
The only App I can see that helps is Network Signal Info Pro...and unfortunately it is limited and shows me the below in my market;
HSPA+ 42.2 MBPS
HSDPA 7.2 MBPS
UMTS 386 KBPS
But, does not indicate which Band or Frequency ?
Anyone know of an App or Command that will show WCDMA Bands???

HTC ONE M9 LTE Bands unlocked version Taiwan

In Taiwan the new HTC ONE M9 offers the following LTE Bands which sucks in you travel abroad often. I saw this info at the Taiwan Mobile shop in Taipei. If you travel to America and want to use T-Mobile then you will be missing Band 12 and other bands which keep you from having 4G LTE in the US. The new Galaxy S6 Edge is the better choice if you are a frequent traveler and want wider 4G LTE Band coverage.
LTE FDD 01,03,05,07,08,20,29
LTE TDD 38,40,41

Asian LTE bands have never matched American and vice versa..
P.S. It was even worse with M7 and M8 though..

Overseas Electronics made an unboxing video of a TW version. I have captured the back of the box. I see only 700/900/1800 Mhz LTE support.
But anywhere else FDD：1、3、5、7、8、20、28 頻段.
Can anyone confirm there is only one Asian unlocked version?

The bands are for SEA (south-east asia) version. Details at http://www.htc.com/sea/smartphones/htc-one-m9/
M8 did not support that many bands; so they have different models for different countries.
For those who travel around Asia including China and possibly Europe, the 4G coverage is pretty good. :victory:

Total of 10 Bands for the HTC ONE M9 and a total of 19 for the Samsung Galaxy S6 Edge in Taiwan. If one does not travel too often this is not much of a concern but if one travels often and especially between Asia and America then the Samsung Galaxy S6 Edge will have the edge over the HTC One M9 because one can use it on T-Mobile's 4G LTE Network in America and get 4G LTE service in Asia as well where this is not possible with the HTC One M9. Not sure why HTC decided to do this. They always manage to find a way to lose a sale.

Believe the 4G bands are provided by SnapDragon chip. There could be other models.
Any idea what is the exact Samsung model that supports 19 bands?
There seems to be many models around as per http://www.gsmarena.com/samsung_galaxy_s6_edge-7079.php

Those bands actually sick unless you live in America. For those that travel the important bands are still missing for 4G LTE

What's the correct model to get for use in Japan (and how!)?

Still love my Z3 but MM OTA update fried the wifi&bt within a week. (Bad Sony. Bad.) So OP3 I'm ready for you.
I'm going to order a USA version and have my friend ship it to tokyo.
question1- Is there a better way to get one? After all, it's originating in China...
question2- Is USA version the way to go? The only info I have to rely on is the result from http://willmyphonework.net :
OnePlus 3 North America Model + Japan + Japan Travel SIM (data only)

Still love my Z3 but MM OTA update fried the wifi&bt within a week. (Bad Sony. Bad.) So OP3 I'm ready for you.
I'm going to order a USA version and have my friend ship it to tokyo.
question1- Is there a better way to get one? After all, it's originating in China...
question2- Is USA version the way to go? The only info I have to rely on is the result from http://willmyphonework.net :

FYI, oneplus chat support referred me to willmyphonework.net. i ordered the north american version to a usa address. its getting shipped to me in tokyo for $26 USPS (6-10 days).

I bought the European model and will have a chance to test in Japan when I get back in September. Will be flying back to Europe for holidays.
As long as your phone supports the 2100Mhz (B1) band it should work (as far as I can tell, I sure hope so otherwise my oneplus would be useless hehe). Coverage in the country side and mountains might be poor but my Ymobile pocket wifi always had crap reception in the mountains anyway so no big change there hehe.
Edit: I believe the USA is a bit special when it comes to the frequencies used. Unless you are from the USA you might be better off when the European model as that seems to have better global support.

North America version ordered from and shipped to USA, then forwarded by post ($26, 10 days) works fine with data sim. I don't have a voice sim here in Tokyo to try.
