network problem - Xiaomi Redmi 3s Questions & Answers

Hi guys,
Please help. My redmi 3s prime has lot of network problems. Network signals keep on going and coming back. Volte is also not stable. In wifi there is no connection problem but in Data on situations can't get signals enough to be able to use met. Service center can't solve my problem. All types of network settings has not helped.

You have a thread here too: https://forum.xda-developers.com/xiaomi-redmi-3s/help/network-problem-3s-prime-t3635728
Are you close to the cell towers? Do you have good signal strength?

I have not such network problems in my area. Problem is as I switch on the mobile data, network goes off. No services and emergency calls appears on top. It has something to do with Data.

Fixed. National roaming not working. Norway

Edit: writing it down helped me understand that i actually never activated "2g or 3g or 4g" in elixir2>information>telephony>turn 4g on.
So this was how i got onecall to work properly, in case there's other Norwegians with the same problem.

In areas where my provider doesn't have reception it uses another provider. My phone then shows that it's roaming and that it has data connection, but in reality it doesn't, i can't access the net. Roaming is activated, the apn of my provider is setup correctly. My provider uses 2g and 3g, the other provider uses 4g as well. When the issue appears it doesn't help to turn on and off airplane mode, doesn't help to turn off and on obile data or to reboot the phone. The problem appears no matter if I choose the other providers network manually or let the phone do it automatically. I tried every possible setting in elixir2 regarding "preferred connection speed - 2g only, 3g onlyn 2g or 3g or 4g and so on.
Anyone with a similar issue on this or a different phone and a possible solution?

[Q] Help! Diagnose network connection issues

Hi guys
My n9005 has been having mobile connectivity issues for a while now. I'm not very knowledgeable about mobile networking and standards so I need some help diagnosing the problem before I either find a setting to alleviate the troubles or get some hardware replaced. For your reference i think has been caused by dropping my phone quite a few times so there is likely a hardware issue, i just want to better understand it to see if theres a workaround before i go spending money!
My phone works flawlessly when it displays its connect to 4G or H+ networks. However when it drops to 3G it usually does not send or receive any texts, calls, and I have no data connection.
I have fiddled around in the service menus and tried setting the band preferences to GWL, WCDMA & GSM, LTE Only, etc etc, with not much luck either having no connection or having the same issue. For reference I don't have 4G coverage at my home only H+, but when I was on holiday in the middle of no where at the National Park (I live in New Zealand) I had 4G connections the entire time with no dropping.
Now I have no idea what mobile networks use what standards/protocols so if you could recommend a setting change or identify what I should get replaced that would be great!
Cheers

Redmi 3s Mayor issue continuous drop to 2g Network with full coverage 3g/4g

Hi all,
I have a redmi 3s, i have a major issue with this phone with one sim configuration
Signals drops from 4g/3g to 2g (edge) with minimal drop of signal. With other mobiles no drop of signal, stay at 4g/3g continuously. Then the mobile takes forever to recover from 2g to 3g/4g at a full coverage of 3g/4g. The configuration at the mobile is preferred LTE. I have tried with other mobiles and the coverage it is fine. With other sim providers and I have same problem.
I am looking for any trick for fix the network mode. I have tried different programs from google play and modifying the build.pro, exposed but the networks mode comeback if you reset the phone or change from air plane mode.
Any ideas?
Thanks and regards
Fix for MIUI 8
Look here or here
Different issue. it is described here:
http://en.miui.com/thread-320293-1-1.html
The workaround is to enable GPS (for example open Maps), the phone will return to 3G.
Turns out, I'm not the only one facing this problem. From the above post, having 2 SIM card active will fix this problem. Too bad I don't have second SIM.

Signal loss

Hi everyone,
I already looked for an answer in the forum but nothing conclusive.
My moto g4 play loses signal during calls. The sim card is 3G and so I changed the network manually to 3g on the phone. However the problem continues and I think it even got worse. It happens especially when I'm moving, in the car, etc.
Is there any real solution for this problem? I have seen many users complaining but I did not realize if there was a solution or not.
Can you help me?
Thank you
Since the SIM is 3G, I'm going to assume the network you're using is GSM (ATT/Tmo). It is possible that the cell towers in your area operate on a specific type of GSM frequency, and your signal loss is due to the phone trying to connect to towers not supported by your carrier. If a call drops again, check the Roaming status of your phone in Settings and see what turns up.
Also, it seems odd that you would have to change the network settings at all. Even if the phone is set to prioritize LTE, it should automatically detect the 3G signal and adjust accordingly.

network mode option to change it to GSM/WCDMA/4G

HI,
Can someone help me to to change the network mode setting to change the mode to either GSM/WCDMA or 4G which will improve cell strength in poor signal areas.
Thanks,

I had to find a solution since my cell signal was constantly dropping switching from 3G/4G/LTE...
With this app, I leave it on 3G/4G, no LTE and everything is now fine. This app should work for you as well
