US users on T-Mobile

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

Network connectivity issues

Hi there,
i am having serious connectivity issues on my MIX 3(bought from Gearbest) in Canada, Rogers/Fido carrier uses B4,B7 for LTE, but I never get that..stuck on 3G for voice and 3G+(H+) for data..tried both sim slots, different "preferred network" settings, nothing works..on chinese ROM and now Global ROM same thing, except Global is even less stable and it drops signal quite often..searched for it, but no results for Mix 3, although a lot of similar issues with other Xiaomi phones..anyone some ideas how to resolve this??
thanks a lot

Did you buy the 8/256 model? If not you may be missing band support.

I have 8/128, but that should be compatible with what i need for my carrier, B4 and B7. Spoke to my carrier tech support, nothing wrong with the sim, or my network...as i said, it was bad on china ROM, even worse after i flashed it to global. any chance it might be modem related?anyone with similar or same problems?

I flashed global on my 8/256 and didn't see any issues.

UPDATE:
Finally fixed it. Over the weekend I went to US and had perfect LTE connection while roaming with T-mobile, so i assumed it wasn't the MIX3 issue..I went to my carrier(FIDO) again and we figured that my APN had wrong name by default.but I wasn't able to change it or create a new one (some sort of blocking from my carrier with Android phones as I read on some other forums..). long story short, search "SOLVED-FIDO-APN-MIUI 10" if anyone encounter same or similar problem...can't post links

Unstable 4G connection

Hello,
is anyone facing the same problem, that the 4G Signal is often very weak and unstable. For me if the signal isnt the best, it switches to edge or hsdpa+.
With my old phone i have got always 4g at the same location... Any ideas? I have already tried a factory reset and changing the sim card slots.

I don't have that issue but I would say that's usual. All phones have different signal strength. It could be that your previous phone had better than op7. And its hardware related. Sometimes you can Improve it a lil bit with another firmware. But in most case there is nothing you can do.

I'm not getting good LTE reception either. I'm in Canada on Bell Mobility. I have the Chinese GM1900 model OP7 running the latest OxygenOS.
I keep switching between the OP7 and Pixel 2XL and I notice that even though the GM1900 supports all my carriers bands, the OP7 tends to choose different LTE bands than my Pixel 2XL does. Also, I noticed that the LTE Discovery app shows a weaker signal on the OP7.
I'm not sure what the issue is, and I am thinking a refund/exchange will be a hassle but I might give it a shot if I have to. I have only had the device since last Saturday so I am still hoping that there is a tweak or even another ROM I can choose to help this.

Nah. Coming from Mi9 I would say its the same compared to op7.
Edit: you could try to change your network type. Maybe there is something wrong selected.

Already tried to change the network type. No change.
Also it should work out of the box. Maybe the next system updates will fix this.

I have the same issue and I've replaced the phone already and it hasn't made a difference.
My partner's on the exact same network and gets 4g where I get H+?! In the exact same place on an iPhone 6s. Go figure.
I think a firmware update/fix is needed.
Anyone submitted it as a bug?
Sent from my GM1903 using Tapatalk

Finally someone with the same problem. This is exactly my problem. H+ where others get a stable good 4g connection at the same place. Where can we submit this bug?
Edit: I have opened a thread at OnePlus. Maybe all with the same problem can comment this so OnePlus actually cares about it?
https://forums.oneplus.com/threads/unstable-4g-connection.1069237/

The Op7 has not been released for my market, is it still ok to submit a bug report there?

Anyone with the same problem?

Can confirm this has been an issue on my 3rd 7 pro, haven't tried on the first 2 before RMA'ing them unfortunately. I want the 7 because I couldn't stand the curves and the weight of the pro in the end so i'm gonna return the one I got now as well....but if this is a widespread hardware issue with both it kinda sucks for me, on most days I use 4g for at least 2 hours.

I think everyone needs to include their views on the issue posted at OnePlus so that they can see how widespread this issue really is.

I'm also gonna return the phone and buy another one if this won't be fixed. It really sucks because with my old(er) Phone(s) I have got better signal strength than with the new op7. This is a nogo for me...

I created a feedback using the Community app, and I also created a log file while having the issue and sent it in with that report.

EDIT: Purchased a Redmi Note 7(the OPO7 costs 3 times more) and i have got stable LTE signal where the OPO7 only gets HSPA+. Gonna sell the OPO7. This is really a nogo for me.
Anyone else with the same problem(s)?

hey, It seems to me you have a problem with the 4g band itself did you try to change it to Europe or Us from hidden settings,
If you haven't tried that may I suggest to do so by searching on google play for an app called android hidden settings, by 0alex..
https://play.google.com/store/apps/details?id=com.kasitskyi.hiddensettings&hl=en_US
and change the band between europe and us and toggle as well between 4g and other modes just to make sure it was changed.
I hope that helps,

Wifi Calling Sounds Crap....

Is anyone using WiFi calling?
I have tried in the house as my cellular network is not full bars.
I have to say it sounds very distorted and crackling.

hmm strange... might be your firmware or something then .. .. i have crystal clear soung on VoWIFI, use it alot as most my friends live in small towns with ****ty to none reception ,,, so always use it there... :/

Hi,
I'm using p40 pro + and Vodafone in Delhi. I'm. Not getting option for WiFi calling. But in my jio which is in sim 2 I have that. Any idea why specifically in Vodafone it isn't coming?
Prior to this I was using S21 Ultra, in that WiFi calling was working as charm for voda.

WiFi calling feature depends on the phone model. Probably P40 Pro + is not currently supported by Vodafone in your country.

Hi, I am using the ELS-NX9 model of the Huawei P40 Pro. I don't see wifi calling feature any where in the phone.
how do you enable the wifi call? maybe you are using a different model?

I don't have 4g

Good morning
I have a samsung a51-sm515f.
I have a problem with 4g. I often have 3g or no network at all. Is it a software problem? I am on android 11. Should I flash android 12 or 13?

More likely a hardware problem. Does this problem also occur in close proximity to a GSM mast? At what distance from the mast do you most often observe 4G outages?
