Find 7a no data on T Mobile network and Oppostyle response

I bought the Oppo Find 7a 2 weeks ago. Everything is great except that the phone would randomly lose data connection on T Mobile 3G/4G network. I am aware of the APN fix and the phone seems to work fine when the data connection is established. I have to keep toggling mobile ON/OFF but it seems more miss than hit.
I also contacted Oppostyle of the issue and it has been 3 days without any response.
Has anyone have similar issues? I bought this one to replace a Nexus 5 (which I moved to another network) and that phone never had data issue in those locations. I sure hope Oppo responses soon. Not expecting this much of trouble from a top of the line phone and I thought Oppo service was good.

Problem confirmed
I have the same issue. Usually once in 24h period.

Hi jebulol,
My success rate is pretty low. I would say less than 30%, data connection would work.
Still no reply from Oppostyle... crossing fingers..

Well so much for buying the 7a
I guess I will wait for the OnePlus One

I've got the international version and get 3G/HSPA+ back and forth, though I suspect the flaky H+ is more due to my area than the device. Seeing ~8Mbps down / 2 up on H+- not going to be setting any records, but plenty for my purposes (all the heavy lifting I do with data is by wifi anyway- I'm on the pauper data plan). If anyone has any particular tests or diagnostics they'd like run I'll be lurking around.

My 7a Don't have these issues. LTE works fine here.
Sent from my X9006 using XDA Premium 4 mobile app

I am not able to get any data connection if i have data mode set to automatic. As my provider offers no 4G anyways i set it to 3G only and that way it works fine. No idea if this helps, just what i found out.

this loss of data is starting to annoy me so much that my 7a could be going on gumtree

I never got any response back from Oppostyle.
The phone has improved a bit after a couple of system update. I would say a 50/50 chance that data would work now. Btw, I live in Houston which is a major Tmobile hub so it seems I got a lemon and Oppo decided NOT to do anything about it.

Yes, I have the same problem. When I got mine initially the data was working. My problem started after I upgraded to the latest software.
I contacted Oppo support and they asked me to perform the following on my phone and send the data back to them. I just sent it yesterday and I'm waiting for them to get back to me. So, you may want to do the same thing and open a support ticket. 1st you will to create an account on the Oppo support web site.
And to save you time follow this procedure and send it to them as well. It's a large file, zip the file and send via your email once you get the acknowledgment from them on your support ticket..........
" Please follow this simple steps:
1. Input *#800# to Dial pad to enter Engineer mode, entry device_log.
2. Click delete histroy log(the first button), then click the open device-log(the second button).
3. When you encounter this issue again, navigate to file manager(path: Files > Phone storage)
4. Copy the folder diag_logs to the computer and compress it to a ZIP file.
5. After you're done repeat Step 1 and turn off device-log(the third button).
Once you obtain the file please let us have it attaching it into your next email."

Apple had about same problems with iPhone3 - solved in 2 weeks

Try the KulayOS ROM, it works flawlessly on T-Mobile LTE.

Also for some reason the APN settings don't stick, so the solution is to create a while new APN then delete the old one. That worked for me.

oppo find 7 data drop
Hey i have the same or similar problem with my oppo find 7t. Most cases the phone shows that data is running but even though it does not work.
I turn off and on the data and then data works for 1-10 minutes if I'm lucky more. Data drops so often...
I have been looking for a solution through Google but have not found anything, guess this is a big and serious problem that exists in all colorOS for find 7a or 7 and OPPO has not solved it.

What Find 7 do you have? The 9007(US version) works flawlessly on T-Mobile. T-mobile 4g operates on band 4 @ 1700 and 2100 Frequency. The international version Oppo F7 doesn't work on the 2100 frequency only 17000 so that may be your problems.

Greetings...
Have you simply tried to do a Factory Reset?
Try that.. and set your device up as "New.. Get A Fresh Start"
And finally.. are you sure your Wi-Fi is functioning properly? you may want to reset that as well.
What about open Hot Spot Wi-Fi's at the Mall or a Hospital... Have you checked your Wi-Fi there?
Don't be quick to send in your device.. it's usually the simplest thing that is the issue.. :angel:

Issues with apps over WiFi after upgrading to Android 9

Hi. At the start of December, I upgraded my Mi A2 Lite to Android 9 and ever since then I have been facing issues with a few apps over WiFi. The following apps are being affected:
- YouTube
- Twitter
- Facebook
- WhatsApp
- Chrome
*These issues are only on my WiFi. On 4G or any other WiFi these issues don't happen*
The issue with Facebook and Twitter is the same. Both won't load any new feed and behave as if my WiFi is not turned on. YouTube only works at times, other times it would just keep loading and nothing would happen. Sending images or videos on WhatsApp is impossible now. It even has troubles making the backup to Google Drive on my WiFi. As for Chrome the issue is that sometimes even though WiFi is turned on, it would not load any page and just say that I'm not connected to internet. I've been reading other people's threads online and even emailed Xiaomi and Google. I tried the steps (hardware test etc) as told in the email by Xiaomi but that has not helped. Some said that using WiFi and Bluetooth at the same time caused this issue but I have used WiFi with bluetooth turned off yet the issue is still there. Now if this was a WiFi issue then I would have contacted my provider but with the same WiFi connection I have not faced a single issue on any other mobile devices and laptops. As for my WiFi I can't seem to change it from ipv6 to ipv4 (or I just don't know how to). If anybody has faced this issue and knows how to solve it then please help, It would be greatly appreciated. Thank you for your time.

Have you tried disabling Bluetooth and then reconnecting to the WiFi in question? Having both enabled at the same time causes WiFi speed transfers to be really bad, it's an already reported Pie bug.

Btw, can u see 5ghz wifi networks?
Cause i can and have same problem with slow wifi+bluetooth

Yes I have turned Bluetooth off and used WiFi like that but the issue is still there with all the apps mentioned

Any update on this? I'm having the same issue. Using a VPN seems to solve the problem but the connection is slower.

I am facing the same problem on my A2 lite Android One Pie. Even the further upgrades including March upgrade did not resolve the issue. It really sucks.
Has anyone found any solution?
Is MI even concerned or acknowledges the issue?
Is there a way to go back to Android 8?

Hello Dear Sajid Abid,
Good Day !
1st Remember One Thing. Downgrade Is Not A Easy Task, Downgrading Has Also A SIM Issue Problem,.But If You Still Want To Go Back Your Mobile Device From Pie To Oreo You Need To Unlock The Boot-Loader (Off-Course Unlocking Boot-Loader Will Void Warranty) Then Download Stock Oreo (From MIUI Forum) And Flash It With The Help Of IMFlash Tool. After Successfully Ported The Stock Oreo Rom You Can Close The Boot-Loader.
All Instructions/Steps Can Be Easily Found On A2 Lite Forum.
Here Is The Link Which Can Help For Resolving SIM Issue Problem.
https://forum.xda-developers.com/mi-a2-lite/help/sim-card-issue-downgrading-pie-9-0-t3874350
Have A Nice Day.
Thanks,
MUHAMMAD Asif Qasim

Suddenly extreme slow wifi speed

Hi guys. I have 100mb fiber internet in my home. I bought a Mi A2 Lite in monday of last week. My Mi A2 Lite stock Android 9 4/64gb works fine, the wifi signal and speed was never a problem, but in the last 3 days my wifi speed goes extremely down. Youtube can't even load the thumbs, the videos don't open, It takes a lot of time to download some app from Play Store, etc. All the conection is extremely slow, like a 2G internet or older. The phone was working fine until the last days, I didn't have installed any new thing, don't touched the wifi router... PC, notebook and another Android devices working fine in Wifi, except my Mi A2 Lite. The 4G in the phone works fine. I've already turned off the bluetooth and location and nothing happens. Already reseted the wifi configurations and nothing, changed the wifi channel in router and no way... This is as far the worst Xiaomi I've ever bought :crying: :crying: :crying:
With speedtest apk the donwload and upload speed can't eve reach 20 kbps. No way to use.
What can I do? Mi Mi A2 Lite is brand new, last Android 9 (10.0.18.0) that I updated in tuesday (and make a factory reset), all working fine until this sh** starts...

Same problem here. Nothing changed, no ota update the last days. Very slow internet connection, tested with different router. Of course phone not dropped or something. Sometimes the speed goes up to 50 mbit and the download also is optimal and reached 10 mbit. I can't see where the problem could be because it sometimes seems to work normally.

Remember this coronavirus thing that's happening worldwide now? Your WiFi is probably slow because most people are home and have nothing to do but stream movies etc.
Yesterday I was supposed to get a free upgrade from 20Mb to 120Mb on my fibre subscription but during daytime I see 2-4 Mb only.

Question Problems with mobile data - Stop working but looks good

Hi,
I own a Xiaomi 11 Lite 5G NE. I have updated to the latest MIUI Official V12.5.8.0.RKOEUXM.
From the beginning, I'm facing the issue that mobile data is not working. You're navigating and suddenly all stop and finally it shows the error no network.
After restarting is working fine again but it's very annoying. I've been looking for help but nothing found has helped.
Is anyone else facing this issue?
Thanks for your help and time!

Post seen by 26 people so far and no answers.
I suppose then mobile data is working fine for all of you... Mmm... My bad, it looks I will need to use the guarantee...

Hey. There
For some Days I also having mobile data problems. My phone så browser says No internet connection..
When i turn phone off or disable mobile data off for 30 min IT Works for a short period, then IT stopps again. I can use Wi-Fi at home.
I have factory restored my Device but its didnt helped. Swiched to second sim slot and nothing..
Gould be cool od someone knew how to fix it. Or need to send it in. Had this phone 3 months .
Specs..
Xiaomi 11 Lite 5G NE
MIUI 12.5.7.0 stable
Model 2109119DG

Same problem here. I'll preface this by saying that I work in a place where the reception isn't great, but with my old Huwaei it never happened.
When I lock the smartphone and then unlock it after a while it shows 4G+ but in reality there is no connection.
Last night at the gym (in a basement where the reception is zero) after I left it wouldn't pick up the network again.
To solve it I have to put on and take off the airplane mode.... Very very frustrating.
I also replaced the sim card with a new one but no dice.
MIUI 13.0.5.0 Stable

Thanks all for the replies.
So I'm not alone, but it looks that some people have not issues.
Looks also problem is on MIUI 12.5 and also on MIUI 13.
I think it is a hardware problem, not software.

In these days Ill take it in assistance and I will update you.
Unfortunately, it has been too many days since my purchase and I can no longer return it. Super regretful that I didn't get a samsung a52s!

Need to that we had igły weather here with lightnings and storm . Many trees was Tilted.
But checked mobile operatora site and nothing there.

Hey again.
I have talked with my phone carrier..
Tv'et said that there ser problems with the antennas or something and in some Days they will fix it . They said i need to chance from LTE to 3G till its fixed..
They should have write something on their homepage. Will have helped , so I didnt had to factory reset.
That's All for now.. Have nice weekend you All.
Hope you will have yours problem fixet.
Bye

I also had major issues with my mobile network on 1 of the simcards. (I am using dual sim)
If your provider supports 5g then call with the dialer *#*#4636#*#*
you will see a menu with 3 options. the first selection is simcard 1 the second simcard 2.
change the prefered network type to NR / LTE / GSM /WCDMA or whaterver ur provider is supporting, NR = 5G network.
Make sure you disable VoLTE for both the sim cards since this was disabling my download from mobile networks.

hi guys, yesterday I took my cell phone out of repair. They replaced the motherboard and now it seems to be working fine, no signal loss.

Hi @ddanielee , that's a great news!
Is it still working since then? All fine?
Did they say something if this is a common issue?
Thanks for your comments and feedback!

Hi Raulci, i replied u in the other thread!

Just wanted to let you know that during the last weeks, I haven't experienced any other mobile data issue again. I have changed anything. Let's see if it continues this way.

Yes its a problem. Initially i thought its miui 13 problem. But reading above comments with slow speed/ 4g connectivity issues in 12.5 it seems its hardware related. Inferior modem or low quality antennas could be the case. I was hoping to fix by reverting to 12.5.

Same problem i have mi 11 x i even go to the service centre they factory restart my device and it's not fixed they said it must bu hardware problem
