Will Mi A1 work with Tmobile in California, USA? - Xiaomi Mi A1 Questions & Answers

Hi everyone,
Does anyone purchase this phone in CA, USA with Tmobile? Does LTE 4GB work for you OK?
I checked on https://willmyphonework.net/ USA, T-Mobile and the results were:
2G
1900MHz Device is compatible with the network carrier
3G
1900MHz Device is compatible with some of the network carriers frequencies. It may work.
4G
Band4-AWS Device is compatible with some of the network carriers frequencies. It may work.
Thank you!

I have it in Santa Clara, CA (Bay Area), its working pretty well.
I hear some bands are not supported, but I've yet to see a network drop.

I'm getting 40 to 50 Mbps consistently

I use it in Puerto Rico and Florida with Tmobile. I can get 80mbps. It connects to Band 4.

I'm about 30 mins north of Los Angeles and my LTE speeds are up and down. I was in the West LA area yesterday and I was seeing 22Mbps. Locally I'll see less than 1Mbps, to 12, to 22Mbps in the late evening.

I just arrived to NYC for short vacation. Tried buying T-Mobile travel SIM card (30$ for 2gb od data and 1000 minutes) but IT didnt worked at all. Guy in the store wasnt able to make IT work. So, im little bit disapointed..

I live in Florida with T-Mobile, it works but it's either 2.5G or LTE you cannot 3G or HSPA+, so if you get bad coverage it will switch to 2.5G which is extremely slow. But other then that it works great. Speeds are good with LTE

Works great in Long Beach CA, USA. 4g and decent reception. Very happy so far.

Techeretic, what APN settings are you using? I'm also in Santa Clara but can only get 3G on this phone. Thanks.

I just got my Mi A1 and I'm in the Riverside area in Temecula. I have been stuck with 3g so far, never had a 4g connection yet. I have the global version that says it supports bands 1(2100), 3(1800), 5(850), 7(2600), 8(900), 20(800), 38(2600), 40(2300). Am I missing something here? Is there another version other than global that you guys are using that supports different bands?

Moving to USA (CA) ...

Hi,
I'm currently living in Europe (France) but I will be moving to California (San Francisco) in early December. I own a blackstone, which I bought here in France.
How should I expect it to work in San Francisco? From what I understood, I might not enjoy 3G+ ... Is that true?
Any informations welcome
it will not have 3G service. Only the Tesla model will work with 3G in the states. My touch HD works works vary well in San Fran but it is the ausy model
As stated there is no 3G service.
However, plenty of free WiFi areas.
​
Ok, thank you very much! I guess there IS a 3G service, but my phone isn't compatible, right? In that case I'll just sell my phone before moving ... Or is it possible that there is still no 3G service in SF??

3G service in available in all major US cities; your phone needs to have the right US 3G bands. for at&t the 850/1900 band is used for 3G, for T-Mobile (i believe) it's 1700/2100.
what he said, so make sure the phone you buy next is North america 3G compatible (850-1900htz 3G). My Blackstone only has 850 htz 3G but I have never had a area where my ATT fuze was 3G and my Touch HD(ausy model) wasn't.
Okay, all clear now. Thanks a lot for all your help.
Cheers

[Q] Which Network ????

Hi All
I am visiting the USA in September for holiday and am doing a bit of travelling while i am out there. I was going to buy a prepaid sim to use with my SGS II which is sim unlocked. I am visiting Los Angeles, San Francisco and Vegas what network would you guys recommend for coverage and costs ?? it would have to be a GSM network.
Thanks
I would say T-mobile because they have a awesome pay as you go plan
I would say T-Mobile
T-Mobile and AT&T are the only ones compatible with your SIM. However the SGS2 is only going to get EDGE on T-Mobile if you're wanting data. It's compatible with the HSPA for AT&T however. From what I understand there really isn't a difference in price between the two for prepaid. Nothing to make a difference when you're taking an international trip anyway.

European 3G bands are different than US ones. In Europe the UMTS band is operating on 2100MHz. AT&T operates it's 3G service on 850 and 1900 MHz.

Yeah but the SGS2 has the 1900MHz band in it, so it would work on AT&T's 3G network, but only on T-Mobile's EDGE.

You need both bands for AT&T 3G. 850 provides downlink. 1900 provides uplink. In Europe, 2110 is downlink and 2150 is uplink. It is normally just included in one spec of 2100MHz. The 850MHz band in this device would only provide 2G speeds.
AT&T is your best bet.

Note 10.1 2014 USA Verizon LTE

Spoke to someone who I trust on the inside and was told Verizon has the Note in hand & is testing it.
They are modifying it and working the kinks out. Conservative estimates are that it will release in February 2014...but the absolute latest is April 2014. These are conservative estimates and it could possibly release earlier.
This is good news. If Verizon is testing it, that means they have a version with 700MHz LTE (and likely 1700/2100/2600 as well).
Currently on the fence about buying the European version with its limited LTE capability. Please keep us updated if you hear more!
don't mean to hijack the thread but dont feel this warrants a new thread...

It will be limited on LTE. AT&T uses 700MHz and 1700/2100MHz for LTE. I'm unsure if they use 2600MHz as well. The three Canadian carriers use 2600MHz for their 150Mbps LTE Max network, which is has limited coverage in major cities.
The European P605 supports 850/900/1900/2100/2600.

What does limited mean?
I'm not entirely aware of how AT&T's LTE setup is, but according to reports there are some areas where they are using 1900MHz and 2100MHz for LTE signals. The note will have connectivity in those areas. However their main frequencies are 700 and 1700 I believe, so in most areas you wont see an LTE signal.

OnePlus One Carrier Compatibility

Hey everyone!
I've been looking on the OnePlus forums lately, and lots of people have questions about carrier compatibility with the One. Personally, carrier compatibility is the biggest factor when it comes to buying an unlocked phone, so I decided to make this thread to help guide people with compatibility with their carriers. According to OnePlus's website, the bands that are supported are as follows:
GSM: 850, 900, 1800, 1900MHz
WCDMA: Bands: 1/2/4/5/8
LTE: Bands: 1/3/4/7/17/38/40
Now, I am going to start with USA compatibility. If anyone else would like me to add compatibility with their carrier, please reply to the thread, and I'll see what I can do. Hopefully, this will benefit all members of the community.
USA
AT&T
2G/EDGE/GPRS : Supported on both 850 and 1900 MHz bands
3G/UMTS/HSPA : Supported on both bands 2 and 5.
LTE : Only supported on bands 4 and 17. Bands 2 and 30 are not supported; however, they are usually only deployed to create extra bandwidth in high capacity areas. Band 17 is AT&T's major LTE band.
MVNOs of AT&T : Straight Talk, Net10, AIO
T-Mobile
2G/EDGE/GPRS : Supported on both 850 and 1900 MHz bands
3G/UMTS/HSPA : Supported on both bands 2 and 4 ("4G" HSPA+)
LTE: Supported on currently deployed Band 4. However, T-Mobile plans to deploy Bands 2 and 12 to extend coverage. So, if you have LTE signal now, you're okay. If you don't, then you most likely never will with the One.

How to figure out whether AT&T or T-Mobile would be best for Straighttalk?
UNITED KINGDOM
It'll work fine on:
EE (Bands 3 & 7 supported by OPO)
Partially:
Three (Band 3 supported, Band 20 isn't by OPO. Band 20 people say will be used for rural areas)
No LTE:
O2 and Vodafone (Both use Band 20 which isn't support by OPO)
3G will obviously be fine however.

You check the coverage map in your area for each of those providers. The one with better service in your area is the one to go for.

I have the Samsung Galaxy Light SGH-T399. It works on T-M's current LTE 1700/2100MHz (band 4), but also 700MHz (band 17), which T-M just purchased from Verizon. A few other newer T-M phones are also made to work on this 700Mhz band. It seems that they were planning ahead.

The OnePlus One also works on this 700HMz (band 17) frequency.
Good news for those lucky enough to have LTE with T-Mobile. The 700 band penetrates buildings better, so you'll have a better signal inside Wal*Mart or if you live deep inside a large apartment complex.

Very true. T-Mo will probably use this band to expand coverage, Good catch :good:
However, it should be worth noting that T-Mo plans to cannibalize (AKA "refarm") its EDGE network into LTE. This may sound great; however, this EDGE that they will be converting will be broadcasted on the 1900 MHz spectrum (Band 2 LTE). The OPO will not support Band 2, so OPO users on T-Mo will not be able to take advantage of LTE in many rural areas and markets.
Will the phone work in India? Vodafone is my carrier.
Portugal
2G - Full compatibility with Optimus, TMN and Vodafone
3G - Full compatibility with Optimus, TMN and Vodafone
LTE - Compatibility on 1800MHz and 2600MHz frequencies which should cover big population agglomerates on Optimus, TMN and Vodafone. 800MHz left out, so outside cities (and probably inside buildings and small cities) it will most likely revert to 3G.

Curious, was this written by OnePlus's P.R. team? Because it really downplays what I consider one of the biggest problems with this phone, namely that it is missing half the LTE bands used by AT&T, the biggest OPO-compatible carrier in the U.S.
The argument, "Oh but they're barely deployed", is pretty weak. The fact is the bands ARE deployed, and they're only going to get deployed more because carriers aren't exactly in the business of wasting their valuable licensed spectrum. In high traffic areas where they're in use I assume it would be pretty desirable to have them because the other two bands might be over capacity, or maybe they aren't even operating on the tower you're hitting.
Everyone seems to be brushing this off. I guess it's OK to settle after all?
Italy
2G: full compatibility with TIM;
3G: full compatibility with TIM;
4G: compatibility with TIM only 1800 and 2600 MHz, band 3 and 7.

I agree, the lack of proper LTE bands really are a turn-off for this phone. Just look at our friends in Europe, whose widely-deployed LTE Band 20 is not supported. I'm not saying that the LTE bands here on AT&T are optimal, but it's worth pointing out that it could be worse. The fact that the One supports Band 17 should be satisfactory for many users; it's AT&T's low-frequency band, so theoretically, it should cover the most people. The higher frequencies would only make sense being deployed in areas with mass congestion. So in cities, it's fair to assume that you'll get lower-than-average LTE speeds.
Now, it could be worse. Take a look at T-Mo users (like myself). We're pretty much getting screwed over. Band 4 LTE, the band that they're using now, is very high frequency. Building penetration sucks. Coverage and range sucks. Their network currently is weak. The new bands they are deploying will be lower frequency, so they should provide more coverage and reliability. However, of course, the OPO doesn't support them, which is a major blow to T-Mobile USA customers.
But hey, for $300 for an amazingly-spec'd phone, we have to expect that some compromises had to be made.

Any H870DS users getting LTE?

Hi Folks,
I thought I had found a gold-mine here in the United States in the H870DS because it has the quad-DAC and the bands look to be compatible with AT&T and T-mobile. The seller listed band 2 LTE and sadly, according to the box, it is not supported and this is one of AT&T's main bands in my area in California. It still has band 12/17, so, I figured I'd be okay. I cannot for the life of me get it to connect to any LTE though. I've checked and re-checked the APN settings, the network settings (4G preferred) and am out of ideas. Does anyone have this phone and have you successfully gotten it to connect to LTE in the United States? I don't have a T-mobile SIM anymore to try.
-Collin-
I believe AT&T SIMs have issues with LTE on non-AT&T devices until the device IMEI is added into their system.
I am not an AT&T user so I forget the specifics but people often have to call in and have the device IMEI added to their account.. or sometimes this happens automatically after a few hours.
What bands are listed on the box? The thread on XDA listing all the bands shows your model as having B2 LTE (Possible the thread is not correct though) https://forum.xda-developers.com/lg-g6/how-to/info-lg-g6-models-bands-t3571221
I have searched some of the AT&T user forums, it is because different areas have different coverage and certain bands are not licensed properly, so you might not get any LTE signals. I do not know if that is true. But my G6 sure does not have LTE whatsoever.
Thanks for the replies guys. Well, I managed to pick up Band 4 when I walked down the street. I still cannot get 17/12 which is weird because it's the primary LTE band for AT&T. The bummer is that now that I know LTE is working, I can 100% confirm that LTE Band 2 is missing. The eBay listings are wrong and the XDA listing is wrong. I've attached a photo of the box. Oh well
-Collin-
I was interested in picking up an 870DS unit myself. I noticed the discrepancy when it comes to band 2. That had me worried, so I did not pick it up. The 870 DS box shows that band 2 is missing. I have to assume that is correct, so I did not buy.
Sorry to hear that i was thinking of picking up the Korean version myself but if I can't get reliable LTE on att no thanks. I wonder if you could return it to the seller since its technically false advertisement
Well this is unfortunate. I just got mine from Ebay today and was wondering why I couldn't get an LTE signal. The seller did list Band 2 so I'm hoping they will refund my purchase or there is a way to edit the radio.
Sorry for the off-topic question but could anyone tell if the H870DS would support 3G simultaneously on both radios (or 4G on one and 3G on the other simultaneously)? If so it would be worth mentioning here as well.

I am using T-Mobile SIM at SIM 1 and my home country carrier's SIM at SIM2.
It is getting LTE at SIM 1 and UMTS (roaming at AT&T network) at SIM 2.
Fi (T-mobile) is working perfectly for me, full LTE. Cricket (At&t) is hspa+ but no LTE.
For the price I am not unhappy even though I usually use cricket as my primary data sim. It's not what I expected but I knew going in I was shooting craps as there just wasn't a ton of information out for this H870DS variant. It's not a huge upgrade over 3t, just needed to switch it up for a while. I am quite enjoying the screen, camera, and HiFi dac without losing my 2 sim setup.
Edit: Sim one does have full LTE while Sim 2 does not.
The references definitely need to show that there is no B2, B17, or B30 for ATT users though, pretty much a let down there.

I actually got Band 4 to connect on AT&T, but it's pretty sparse and not reliable. I switched that line over to T-Mobile and it works perfectly just as you describe.
I like the phone a lot more than I thought I would. It feels so solidly constructed and the camera I really missed from the V20. I prefer this camera to the one on my S8 9 times out of 10. It's a hair slower to focus, but everything else is better for me.
What's odd is that on AT&T Band 12 is supposed to be compatible with Band 17. On T-Mobile, I connect to Band 12 just fine, but not on Cricket. Oh well, my Cricket line has been canceled anyhow

I'm in San Francisco and unable to get LTE on AT&T or T-Mobile on the H870DS. These LTE bands are listed on the box: 1, 3, 4, 5, 7, 8, 12, 20, 26, 28, 38, 39, 40, 41.
Hi there,
I'm in new Mexico on a at&t go phone plan and on a h870ds.
and I'm defenetly getting LTE.
Does the LG G6 actually reveal the used channel and so the frequency band?
On many Android phones this information will show up after dialing *#*#4636#*#* and tapping "Phone Information" - on the very bottom of this screen you will find a list of available cells including their channel number (called EARFCN for LTE/4G, UARFCN for UMTS/3G and ARFCN for GSM/2G). You can then lookup to which frequency band the EARFCN/UARFCN/ARFCN belongs, e.g. at http://niviuk.free.fr/lte_band.php
Take a look at the 'LTE Discovery' app. The free version will probably have what you need.

As noted on the box as well as other first hand accounts, the H870DS does support both B4 and B12 required for T-Mobile. My G3 and my wife's previous 860N both connect(ed) with B4.
On top of this, I now have a solution to the problem via updating the APN settings. The magic change was simply adding ”xcap” to the APN Type setting and setting the Network Mode for SIM1 to GSM/WCDMA/LTE auto radio button.

It's possible that if you're in an area where only T-Mobile B2 or ATT B30 is available then you wouldn't have LTE.
Was finally able to get 4G LTE in AZ on Band 4. Create a new APN with these settings and make sure network is GSM/CDMA/LTE Auto.
Edit: Also, I had AT&T update their system with the IMEI number of this 870DS that I'm using. That might have something to do with it. It took a couple of weeks too.
