Does anybody know or experienced if an unlocked Skyrocket works on European cell carriers with data and voice?
Our 3g here in Belgium is on 2100 mhz and I seen that the Skyrocket has the 2100 mhz radio, but heard it only works if you have an AT&T sim.
Thanks in advance.
Got my SkyRocket (AT&T, unlocked version) and it works flawlessly in Belgium, Germany, France and the Netherlands so far. No problems at all connecting to voice, voice mail, data on Edge, 3G and HSPA+. GPS and Google Maps works great. Very nice phone!!
Good to know. I have a customer her that wants to use his over there. Now I just have to help him unlock it

Flash or use Odin and install the Rogers stock radio(XKJ7), it works best for me here. More dependable when it comes to locking onto cell signals and less battery is used when it's searching for data networks. I'm also running Jugg v4.1 from the Tmobile dev forums. It's based off of Rogers as well with no CIQ. Also faux kernel from Tmobile for extreme smoothness and lag free phone use.
Just throwing this out there and hope it helps somebody along the line. I travel mostly between Germany, The Netherlands, France, Luxemburg and live in Belgium. This setup has proven to work flawless for me. Bluetooth in my truck as I travel, wifi as needed, data network the entire time I travel and I always have cell signal. While on the road traveling my battery can last anywhere between 18-22 hours
Is it no problem about agps fast fix issue?
I think att device using att agps supl server.
So another country can't access
Att supl server, may be it will cause slow agps fix.

Hi
Do you mean that you flash the T989 rom to our T727 phone ?
Hi Guys, I am planning to buy this phone, I am from Mexico and before I make the purchase I have a few questions and since I have been around with the HD2 for about a year now, I don't know anything related this one.
- Is there as much development for this specific model as the vanilla S2 one?
- I saw in a sticky thread that there is a way to unlock a S2 with an app, is it possible with this model?
- Since I will be using it in Mexico (Telcel carrier, GSM) I won't receive the ICS update right? but I guess I will be able to root it and then upgrade it following a guide in the Android development subforum?
- Does anyone tested the MHL (HDMI adapter) with this specific model or at least with the vanilla S2? How is it working so far?
- What are your thoughts overall about this phone?
Thanks guys, I posted this as a thread with no luck but I would like to know your opinion

Yes the hardware is the same, it also works in reverse. It's an I727 not T
i think this phone will work pretty much anywhere in this world as long as there's umts. I think it has 850,1900,2100 and also i believe it works on 1700 too.
Although we don't have that many development compare to internation s2, we still have some great development ongoing here.
for the ICS update, you can just flash it from here as long as it arrives.
Also you can flash the tmobile version rom to our phone too.
I'm using the Skyrocket fine in Sydney, Australia.
My 3G frequency is also 2100 MHz. We don't have LTE here yet but the HSPA+ speeds are amazing on this phone. On my old HD2 I was averaging about 3.5 Mbps. On the Skyrocket my average is about 7-8 Mbps with my highest test being 12.77 Mbps.
Not sure what the "agps fast fix issue" is but I've had no issues with the GPS. I'm using GPS Status to download the data file. My average lock speeds are between 5-7 seconds.
The only complaint I have about the phone is the whine/hissing sound I get from the audio at low volume when playing music. Other than that I'm loving the new phone: the impressive responsiveness, faster than ADSL2+ data speeds, very bright screen I can use outside in the sun and the sexy white case with the 'HID' back lit capacitive keys.
All the rom for i727 or T989 all work with i727 . The best radio is : T989UVKL1 .
BTW , compare to my all Samsung GAlaxy S2 i9100 , the i9100 have better singal .
I think skyrocket does not match our korea 2100 mHz network.
Data disconnection often appear, poor signal bar, can't establish call in some area.(like bed room)
I also flashed i727r, T989, T989D radio, but all problems are same.
So i decided my phone changed to T989 hercules.
Is it a good idea?

I'd like to ask, specially PARADOGZ and TREATCON, if any of you perfomed a special procedure to make the phone work on 3G or 3G+. I live in Brazil and bought a I727R(Rogers). My carrier name is CLARO and it works on 2100Mhz... everything is working fine (phone call, wi-fi, 2G) except that I don't 3G .... 2G is very very slow.
when i go to phone status i get a variation between UMTS and HSPA and the symbol on the screen actually says I'm on 4G (3G or 3G+ on brazilian saying) but...of course this is not real....data goes lower than 50kbps... believe.... i'm not mistaken.... only 50kbps....
something is definetely wrong.. please help !!

I'm confused... specs states that I727R works on HSPA 2100 but I can't find WCDMA 2100 on *#2263#. so I can't disregard is a hardware issue.
I hope that the solution be only software.... maybe update BASEBAND....
I need help and I'm very worried.

I'm gonna use my at&t skyrocket in turkey. So is stock radios make a problem wtih custom roms?

USB unlock? sorry could you elaborate more please. Is it a file to download/where? or which website you bought it from?
(well, everything short of new SIM card)
The situation:
-bought a 32GB N5 from a guy
-I'm on Rogers in Canada
-on Lollipop
-cannot get LTE, only 3G and 4G (H)
-APN is correct
-checked everything in *#*#4636#*#*
-cleared cache
-reflashed facotry image
-tried Cataclysm
SOMETIMES, I'll get "LTE", but it's a phantom - there actually isn't a connection at all.
I've swapped phones many times before; never had an issue. I read in threads someone saying that on AT&T that you need to register IMEI with them to get new device working with LTE. I never had to before, but called Rogers to check if this is something they've started doing.....no.
Under device model, it doesn't say either 820 or 821. It says "Nexus 5"
I started thinking that I stupidly bought the international model off the guy, but then when i was in fastboot mode I saw that it did say 820.
So.............I'm stumped, puzzled and pissed.
Does anyone, ANYONE have suggestions or ideas? Many thanks!
Sanity check but worth investigating:
- Definitely have LTE coverage in your area? I assume other phones around you connect to same LTE network no problem
- Does the SIM connect to LTE in another known working phone?

Yep, coming from my old phone. Have always had coverage in all the areas I've been with this new phone. LTE SIM, LTE area...it SHOULD work, but is not.
Try a new sim at the store, if it doesn't work return it on the spot. No harm, worth a try
Does 3g work? What bands does your carrier run in your area? You might try the diag LTE screen (requires root, there's an app from the Play Store) and see what band it sees. Also have you tried doing a scan of which carriers are available?

3G and 4G work.
I went to Rogers store and got a new SIM. No change.
Same thing...
I'm just posting to let you know I've had EXACTLY the same problem..
Mine occurred after I smashed the screen and sent it away to a company to be repaired. My N5 came back with a new screen, so immediately I upgraded to lollipop...
Then the LTE stopped working. Occasionally the device would say it was connected to 4G but, like you, it didn't work when it showed this. I tried everything, flashing, checking access points, flashing different radios...but nothing worked.
Now I can't work out if the repair company had somehow damaged the 4G antenna when they were fixing the screen. So I sent it back to be repaired (again)
Now i've got it back. 4G works but it has lost a lot of speed. Where I was getting 25mb/sec on average, I now get 10 max.
I've e-mailed the repair centre to find out what they did, but honestly, I've given up a bit now...
Wait, you upgraded to Lollipop? You realize that they included a new radio right? Try reverting modems.

Hi,
I have recently purchased a used OnePlus One 16GB Unlocked phone from CEX, and it looks and performs great. However, upon trying my SIM it shows No Service/emergency calls only.
Ironically enough emergency calls arent possible either. I'm with giffgaff, (O2's network) and it would not make/receive calls where I live (West-London). Tried a Lebara sim too, same results.
IMEI number is fine, checked with CheckMend. Faffed about with APN settings, manually connecting to the network, but while I'm home it could hardly find O2's network and even then it shows no service. (usually finds EE and Vodafone but I haven't got those sims.)
Took it to work today and it seems to be working "fine" at work. What I mean by "fine" is that I can make/receive calls, watch HD youtube videos no problem, but download speed from various websites and from the play store would be about 20kb/s and connection would drop every now and then. Switching between 3G and 4G makes no difference whatsoever. Also tried the *#*#4636 options but if I switch preferred modes it doesn't save, it defaults to whatever it wants to upon reboot.
It improves outside of work and it's pretty usable, but it drops just before I get home. This area does have bad O2 coverage but with my old Samsung Galaxy S2 and sh*tty Sony Xperia E1 I always get a decent signal even at home.
So originally when I thought it had a dead antenna, I thought I would return and get a replacement, but upon googling around I found that OnePlus is at war with O2s network on some devices, so I might have the same issue. Flashing isn't really an option as I've never done it and even though I'm within 30 days I don't think I should brick it.
At this point if I get a replacement I might have the same issue, if I change networks I might have the same issue. I have a hard time convincing anyone at work to lend me their sims for a day.
Any advice would be appreciated. :fingers-crossed:

Could be band issue,but as you say it works on work(outside home) then for sure the sim is compatible with OPO bands.
This issue can be fixed by changing firmware of the device.
I know it would be seem hard at first but it's worth the work.Flashing firmware can greatly increase your signal strength and likely to cop out any issues with data and calls.
But first you need to flash Custom Recovery Twrp and before that you need to unlock the bootloader of your device.
To start with,
https://forum.xda-developers.com/showthread.php?t=2788632
You don't need to do the root section,just the bootloader unlocking then flashing Twrp.Its easy.
https://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-lollipop-t3300907
Here's a firmware compilation thread just try them and use the one which suits your carrier the best.
Good luck
Hi folks,
I've got the US LTE original Shield tablet, which is the replacement that NVidia sent me for my original "pyro edition" tablet. Since ATT haven't released the Nougat (Android 7, software package 5.0 or 5.1) builds for this tablet, but the ROW tablets are able to get this update, I flashed my tablet using adb/fastboot with the full ROW 5.0 package downloaded from the NVidia site. I then connected to WIFI, and let it pull down the 5.1 update. Factory reset, flash TWRP, rooted with SuperSU. Easy peasy. Then I set up the tablet with my accounts and such.
Based on good info from user @Son-j I made two build.prop edits, changing ro.build.flavor to wx_na_do-user (was wx_un_do-user) and ro.product.name to wx_na_do (was wx_un_do). This changed the reported signal type from H+ to 4G. Unfortunately I'm having trouble finding the thread where he suggested doing this. I think it was on the geforce web forum.
The only problem I've found so far is that I'm not getting LTE speeds. I was in Chicago for a couple days, in an area with strong LTE signal, and my other devices were reporting LTE and getting ~20Mbps down / 10+ Mbps up. My Shield was pulling maybe 8 Mbps down at best , and 1-2 Mbps up. At home in my suburban location, the difference is negligible (most devices here do 5 Mbps down / 1 Mbps up, LTE or 4G).
Still, I'd like to fix this if possible. Are there further edits or flashings that will let my US device running the ROW build get LTE? I have gone in and verified that my APN settings are the recommended ones from ATT. These showed up automatically, and matched the ATT recommendations.
Thanks in advance!
Hi I'm not sure but I there was a thread here in XDA that says it's still difficult to change the LTE (RoW to US, and vice versa) bands because developers couldn't find yet which part of the code to modify... It's not also confirmed if it is indeed possible to change the LTE bands to support.
So basically, flashing RoW LTE on US LTE device will still result in US-LTE supported bands. That's what I understood.
But what you did is quite a revelation. Can anyone else confirm that modifying the build prop will work? Boy I'm excited!

Hi @Son-j -
Thanks! Do you happen to remember which thread had those two buildprop edits? I found them after seeing a post from you a few days ago, but now I can't find it at all. My google mojo has fled me.
I'd like to have a link there so others can see the original source.
It would be nice to get LTE speed, if someone knows how, but most places where I use the tablet don't have super fast LTE, so the difference for me isn't enough to make me downgrade to the marshmallow US LTE build. I'll stick with nougat for now, and hope eventually to get full speed. Who knows, maybe ATT will eventually release the 5.1 US LTE build...
For clarity here is the set of APN settings I'm using. I'm going with the column in the center at the bottom for Tablets:
https://www.att.com/esupport/article.html#!/wireless/KM1062162
All of this was correctly entered by default except I did need to edit two keys:
APN was listed as broadband instead of Broadband (yes, I'm picky, but wanted to match case)
APN type was listed as just default. I edited it to match the listed setting of: default,mms,supl,hipri,fota
Also I'm set to LTE for "Preferred network type"
Ok I think there's a misunderstanding. Uhm, I'm trying to look for the related posts here at the Nvidia threads but it seems to have disappeared.
Just to set something straight, LTE speed is influenced by:
1. LTE device with specific supported LTE bands
2. LTE sim
3. Location with LTE signals
I take it that for your specific device - US LTE Shield Tablet (just like mine) - you satisfy all 3.
For the record, flashing RoW LTE on our US device won't change the supported LTE bands (check baseband code in About Tablet section of settings). So if you used to have AT&T LTE speeds/signals using US LTE ROMs, it shouldn't change if you flashed RoW LTE ROM on the same device.
We are speculating though that there might be a way, software/firmware speaking. We are hoping it's not hardware-baked.

Thanks Son-j. It kind of freaks me out that just a week ago I found the thread that recommended those two changes in buildprop, but now I can't find it, and apparently neither can you! So maybe I'm not crazy, since it's more than just me having problems finding it.
Anyway, yes, I used to get the LTE indicator on the tablet, when in an area that has decent reception of those bands. At my workplace, which is a building built like a Faraday cage, we can get only ATT service, via repeaters spread throughout the building (I switched from Verizon in part due to this). Phones almost always report ~3 bars of LTE in places I usually find myself within the building. However, speeds tend to be <10 Mbps (tested using Speedtest.net from either my phone or tablet). So, despite getting "LTE service" there (prior to my software update), the speeds were nothing so great. For this reason, I'm not TOO worked up that my US tablet running ROW software isn't reporting LTE... most places where I use the tablet don't have blazing fast LTE, and the difference between the 4G service it actually gets and the LTE it "used to get" is not that great.
I would like to fix the problem if possible, but it's not a critical thing, and I may just put it on the back burner until the US LTE 5.1 image comes out, then flash back to that. I've got lots of other fish to fry these days.
Always interesting discussion. Thanks Son-j!

If it's just a speed issue, that will be the provider's end. If it's a signal issue, that's device problem.
It's possible to get an LTE signal but with HSPA speed in some areas.
There is an app called LTE Discovery. It will tell you which band it is currently connected to. I've got it on my tablet on T-Mobile. I am having problems with it connecting to anything other than 3G. But I have read others with the Shield tablet having similar problems with T-Mobile.

Thanks @caseyatbt,
I was unaware of that app. I downloaded it on my phone (which gets LTE just fine at my house, most of the time) and it reports all kinds of fun stuff about the LTE signal it's connected to. On the US Shield tablet running ROW stock, this is what I get, which frankly makes me think the tablet is connecting via CDMA of all things, despite having chosen all the correct options in the Settings / Mobile section:
The fact that my radio seems to be connecting to WCDMA instead of GSM is kinda freaking me out, folks.
I'm tempted to try flashing the US LTE device Marshmallow recovery image, and see if that fixes it. I understand the flashes don't change the baseband, but since I flashed 5.0 and the the device did an OTA update to 5.1, that might have changed the baseband, eh?
So, if me flashing the marshmallow files doesn't fix it, I might reflash an earlier edition and let it OTA to latest edition, which presumably would install correct "latest" baseband for the model.
We'll see ... I'm still not committed to one direction or another.
Marc
OK, I just flashed the 4.4.0 version of Marshmallow. (full flash of all Nvidia recovery image files). After letting it reboot the first time, it checked for update and found none, as expected.
NO LTE. Downloded the LTE Discovery app, and it still only sees WCDMA signals. Uggh.
Now I'm going to install the 4.3, and let it OTA to 4.4, and hope that refreshes the modem/radio. If anybody is following this, wish me luck!
EDIT: OK, I'm in idiot mode. I downloaded what I thought was the 4.3 US LTE image and it was actually the 4.3 ROW image. I didn't notice this until after flashing, and seeing the H+ icon, and noticing lack of ATT usage tracking app. Oops.
I don't see the 4.3 US LTE image on the site; I'm now downloading the 4.1 image, and will do OTA updates from there, checking as I go how which signal my radio is getting.
No Joy.
I flashed US LTE 4.1 image. AFter the flash, LTE Discovery still reports just HSPA+ signal from WCDMA towers. I then let it take the OTA for 4.4... the latest available for the US LTE tablet, and after it ran through its update process, I'm still on WCDMA.
Uggh. I doubt there's any WCDMA signal where I work so I may have killed my tablet, at least as far as using it at work is concerned.
I'm sure there IS a path back, I just can't imagine what it might be, at the moment. I'll start a new thread to be more specific to this current problem.
Sigh.

I just checked my Shield on T-Mobile. In the same area on LTE Discovery that yours says W-CDMA mine says the same thing (under Neighbor Cells). When you scroll to the bottom, what does it say for carrier?

Here are screen shots of my sim status (personal details redacted) and the LTE discovery window:
I am thinking that it is possible that W-CDMA doesn't mean what we think it means. It shows you connected to AT&T so you are not on someone elses network.

I talked to ATT. It's sort of their backup network, not available everywhere. My other devices definitely show LTE. Will post a screen so from my phone a bit later which shows that.

Here are some pictures taken from my phone, which is working properly. In settings, you can see the LTE network type and in the LTE Discovery app screen capture, all the LTE towers.
ATT maintains a "vestigial" WCDMA to allow some level of connectivity by devices that don't have GSM/LTE, but it's not everywhere and it's pretty slow.
The Shield used to show LTE in the Settings Cellular network type, as well as giving the LTE icon, when appropriate. Now it's just HSPA. Sigh.

My T-Mobile phone shows similar to your phone with LTE. T-Mobile must have a similar vestigial WCDMA that is showing up on my tablet. I still haven't found anyone that was able to get T-Mobile LTE working after it was only giving them 3G and HSPA. I have heard it either worked or it didn't.
My F1 Global Version arrived this afternoon. I popped in my T-Mobile SIM and set the phone up. I've been using it for less than an hour.
Good News:
Voice works fine. I made multiple test calls with WiFi off. All sounded great.
Bad News:
So far I've not been able to get a data connection via 4G. It says I have service but pages won't open. I'll play around with it more.
Anyone else on T-Mobile in the US and able to get data?
EDIT: Data seems to be hit-miss. For the last 20 minutes data seems stable.
After about 10 hours of use, I can confirm that US T-Mobile users cannot get 4G on the F1. Even though it says it has an LTE connection.
Voice and 3G work fine. If you're planning to use this with data on T-Mobile, you might want to look elsewhere. I use mine mostly on WiFi so not a deal breaker for me.
I too am on T-Mo and live in Chicago. Voice sounds great. Same experience with data - the phone shows "4G" but I am getting 3G speeds. I've run Speedtest numerous ties, and I'm consistently getting 10 Mbps down, and a few up. Absolutely adequate for my needs (Spotify, email, etc.). In fact, Spotify runs so much faster than my previous phone, that it is a huge improvement for me. So, I've had the same experience, and for me, as well, 3G is not an issue.

My Speedtest results are attached. There's some variance, but about 10 Mbps down on 3G. Of note, the Wifi results are crazy, and easily 2x faster than my previously phone (LG V20) on the same exact network. In my experience, at both home and work, the Wifi on the F1 is ridiculously good.

I agree on the WiFi. I have FIOS gig service I'm getting 400 MB down and 450 up at home on WiFI. with the F1. Better than my S9+ or OnePlus 6
I'm very impressed by the F1. More so than I thought. Just waiting for my unlock code. I have not run into an app yet that has given me an issue. I'll be testing Android Auto later today when I get home. This is truly a nice phone at an amazing price. While no 4G is disappointing, I'm wondering if the band is there, just not turned on. Won't be the first time we have seen that.
Come on development!
Thanks for the follow-up. Also, although a little off topic, I'm interested in hearing about your experience with Android Auto. For me, "Ok Google" isn't currently working. I understand that's a Google issue, not a problem with the F1 (I hope). Haven't been able to text in the car, like I usually do, so I'm anxiously awaiting a fix for that!
My pocophone will not connect to T-Mobile. I have the correct APN settings and it does not connect. I'm surprised you guys are seeing connectivity. I'm in the new york area

Just information "OK Google" command already fixed on miui 10 8.9.11 closed global beta rom,,,
Thanks! Here's hoping the F1 updates to MIUI 10 soon!
Compared to my Mi A1 or Redmi 4X I don't get a LTE symbol here in austria (three), speed is probably mediocre.

Weird. Have you reset the phone with the SIM in? Selected USA as country?

I've done everything. I even unlocked the boot loader and still nothing. I downloaded the LTE discovery app and it will connect for 2 minutes then drop. I think it's a software issue. I'm on 9.6 build

So you can't get 2G or 3G? No TMo connectivity at all? Sorry for all the questions - I have a trip to NYC in December, and want to know if I'm going to have a problem!

I assume the SIM works in another phone? If not, could just be a bad SIM. If not, maybe you got a bum phone. I'm 60 miles from NYC and only LTE is not working.
It will be another day before I can test Android Auto. Wife has that car and working late tonight.

My sim card is fine. It works just fine with my other phones including my new Xiaomi Mi max 3. I'm getting LTE connection. This is why I don't understand why this pocophone won't connect.

T-Mobile has Band 5 in limited markets (which F1 includes). 2, 4, and 12 are prevalent in NY. My current phone has B5 and I've never seen it connect to that band personally.
As for OP. 4G is probably HSPA (3G) but that's very slow. Can you use Network Signal Guru to confirm signal type?

My phone is not rooted so network signal guru doesn't work. I did however install LTE discovery and that was a failure. The app didn't work because I wasn't connected to T-Mobile network

Same here. Got it yesterday and requested unlock code last night.
