My native cellular operator has very bad internet speeds.
However, when i'm in some area which isn't covered by my native operator, i'm able to use network of other cellular operator, whose network is so much better - but i'm able to do it ONLY when there is no my native operator coverage.
My question - is there any way to be always connected to that other operator? If i select it manually, it quickly switches me back to my native operator.
I'm ready to root my phone, if there is any way to do it - I have Xiaomi Redmi Note 7.
Thank you in advance
Have you tried changing the APN?
yes... phone is still on native network
By default, in "Mobile Network Settings" network operator is set to "automatic". But there's an option to "manually select". This will then scan for available networks, and let you chose one (obviously only possible with the desired network in reach). Having done that, whenever the chosen network is not available, you'd simply have "no network" – it wouldn't switch to any other operator, however strong his signal might be.
At least on Android Nougat this works ...

[Q] Unselect "Use only 2g networks" causes phone to loss connection to network
Since Monday my Galaxy S2 can't use 3g networks anymore.
It only connects to my carrier if "Use only 2g networks" option is selected, otherwise it won't give me the possibility to make calls.
Anyone has a clue about what should be ruining the radio communication?
Is there a way to try to "reset" the carrier configs to the default?
I mean, I hadn't change a thing but on Monday my carrier had some signal issues in my area and I think this could be the reason of my phone's confusion.
More than likely carrier issues.
Please contact your provider to see when the work / fault will be completed.
Please update me with your progress xd, who is the carrier by the way?
fkofilee,
But if the phone can't connect to 3g, it should still connect to 2g networks, right?
I mean, unchecking the option should not make the phone lose signal, because 3g would be only another way to reach the carrier.
I'll try with a SIM card from another carrier to double check.
The carrier ir OI, I'm at Campinas-São Paulo-Brasil.
Unchecking the option will disconnect the phone signal very briefly.
Please ask your carrier tech team to give you carrier APNs info.
That way you can be sure the info your getting is correct.
Also check your APN settings...
All of sudden everything is back to normality.
Surely it was carrier's fault.
Thanks for the answers!
I was wondering if there is a way to permanently select a operator?
My network operator (Play) allows free roaming on other carriers inside the country (Orange, Plus, T-Mobile)
I get horrible signal in my work and at home with my "home" carrier and I always roam on one of the others. But I have to manually select that network and every so often I get a "refreshing SIM" message and it switches back to my home carrier (Play) which then gives me 0 bars. I then have to go into settings and select a roaming partner all over again (and this happens at least 2x/day)
Is there a way (either by editing a file/deleting a file or some app) that I can force my phone to only and always roam and not connect to my home network?
pssss.... there is top secret solution... when you will be in the roaming range, go to mysterious hidden menu, called: Settings.
Then, in the section called Network, go to the Mobile networks sub section.
When you'll be there, you possibly would find the most hidden secret feature: Network operators selection mode.
when you will enter this one, you can choose between manual and automatic operator selection.
Please do not populate this advice, is for highly advanced users only, and because of that it is hidden so deeply... in the secret document called: Owner Manual.
haha funny. But if you read my post you'll see I do manually select the network, but it still kicks it over to the home network every day.
if you unticked auto mode, it should not switch back...

I did but it clicks back when there is some "refreshing sim data"
I looked more about the operator and it seems others have this issue with their android phones. It seems the operator forces a network update (I guess to cut down on their fees they pay to the other providers)
So my option would be somehow removing the home operator from the list of operators that the phone can connect to (if there is such a list) or some app that forces to only go on certain networks that I pre select. Nothing is set in the network providers as auto, everything is on manual.
Or of course change providers (but I'll have to see what the canx policy is)
Hi.
I am using a virtual network operator which relies on 3 different networks:
1st is his own now-in-deployment network
2nd that has no 2G
3rd that has 2G and 3G.
all three networks uses the same network name.
I usually manually select the third network through Settings->Mobile Network->Network Operators.
unfortunately, after every reboot of the phone (Nexus 4), it doesn't register on the network I selected, and I have to search it again and select it (it CAN find it when I search for networks).
my ultimate goal is to use tasker to switch between networks relying on the MCC which is different between all three.
is it possible to make the phone use a specific network operator based on MCC, and initiate a network refresh so it would "catch" that network?
I'm talking about a command I could issue through terminal emulator (shell).
my needs are somewhat related to this thread: http://stackoverflow.com/questions/...n-network-provider-as-soon-as-it-is-available
which is unanswered fully.
I'm rooted and willing to make the appropriate changes to system apps and recompile my OmniROM if needed.
thanks :good:
My H961N does not allow me to independently set my network band for each sim card. Both my network providers operate on 2G/3G/4G however since I have gotten this V10 I have had inconsistent network usage. At first I would strongly get one network and the other would mostly be on Emergency Calls when indoors depending on where I was. I used the hidden menu code *#546368#*961#-> Field Test -> Modem Settings, from Modem Settins I have tried to set the RAT Selection and the Network Mode however when I check Engineering Mode both sims show the same band if I am on WCDMA Only or GSM Only but neither provider operators on the same band except for one on 3G. If RAT is set to selectively move between two or more frequencies then one sim shows Invalid Band in Engineering Mode. Using Network Mode I have tried to set each sim to different band but both would either show the same band or one would appear invalid under Engineering Mode.
Another Issue I have is I am unable to use data even though I have the correct APN for both of my Network Providers. I have verified that both sims do work when used in another phone, at one point I visited both Providers but none could give me an answer to my issue. One of my Providers did however try and activated a data plan while I was in their office and the V10 did show 3G and received data however upon returning back to my regular surroundings I no longer got any data. I have tried upgrading the V10 to Marshmallow and Nougat but the upgrade did not solve this problem, neither the one I stated before. But on Nougat both my sims did show 3G but strangely only when I have my Wifi active and using a VPN. Currently I am on Lollipop and rooted I considered trying to flashing a qcn, sec and nvm files since I saw a site listing them as fixing network and data issues on this particular phone, I have the files just in case. Any help would be greatly appreciated.
We have a small local carrier in Southeast Oklahoma called Pine Cellular. They roam on ATT. When ATT recently turned off their old networks, it caused problems with roaming for Pine. They told my mother-in-law she needed a new phone with volte so I bought her the Oneplus Nord N200 5g as my son has that phone on T-Mobile. Insert her sim card and wifi calling and volte still don't work. Insert my T-Mobile sim and they work fine.
I took the phone to a Pine store and they lady even put in her personal sim which had allowed her to roam in Dallas (so volte was enabled) and it still wouldn't allow volte or wifi calling. She said Pine was in the process of updating their systems but she had no idea when it would start to work. They sold my father-in-law a cheap Alcatel and it works fine. I had been convinced it was something to do with the settings on my mother-in-laws sim until the sales rep tried her personal one.
Can anyone tell me what the heck was going on and why the phone wouldn't work on their network? I'm assuming it has something to do with Pine Cellular's internal settings but really WTF?
No one?
This was an unlocked phone bought from Amazon. It worked with the local Pine network, just Wi-Fi calling did not work and VoLTE did not work for roaming, but I could make and receive calls within the Pine Cellular service area. The old Pine Cellular network was GSM.
The Wi-Fi calling menu options appeared when I inserted my T-Mobile sim.
It sounds like you purchased a carrier variant (T-Mobile) version of the N200 (DE2118). Your phone model number is different than the unlocked generic version of the N200 (DE2117). AT&T operates its VoLTE network using whitelists. This means that AT&T will not use VoLTE with any other phone models than the ones they have approved on their list. Since AT&T has "shut down" 3G, phone calls can not be placed on their network without the use of VoLTE.
Only the unlocked generic version DE2117 is on their whitelist, as you can see here:
https://www.att.com/idpassets/images/support/pdf/Devices-Working-on-ATT-Network.pdf
You will not be able to use VoLTE on AT&T with that model of phone.
Wi-Fi Calling is similar to VoLTE, and operates under the same restrictions. (VoIP over Wi-Fi instead of over LTE cellular).
VoLTE is not a true standard. It relies on the implementation of custom VoIP software unique to each carrier and each device. Hence not a standard. The goverments have not forced carriers to standardize 4G like they did 3G, so the carriers have not. AT&T is using this chance to restrict access to their proprietary VoLTE implementation as a weapon to lock down phones to AT&T approved models with locked bootloaders and/or restricted software.
Many phones which support the VoLTE "standard" are not able to operate in VoLTE mode, neither with AT&T nor the other carriers. Even changing the system software on the phone can break these proprietary VoLTE implementations, as I have found personally.
It was the unlocked version. It did work on pine cellular. She could make and recieve calls on the phone network, just not roam because volte could not be enabled.
Amazon.com
In that case, there are many steps to getting VoLTE working roaming on AT&T
1. The SIM card must have proper settings in it, sometimes requiring replacement of the SIM card.
2. IMS software must be installed on your phone (the proprietary VoLTE software made by your carrier). If you are running stock software, this is already done.
3. APN (IMS) settings must be correct. It seems your local carrier is still running 3G, and you do not need VoLTE there yet, so the pine cellular APN can be skipped.
Two APN entries are needed, one for data (carrier) and one for voice (IMS).
One will be named IMS with uniform settings, the other will be named after the carrier, with specific settings.
Settings -> Wi-Fi & Network -> SIM & Network settings -> Access Point Names -> APNs
Uniform IMS settings
VoLTE－Manually add the IMS APN - SUN Mobile
SUN Mobile
www.sunmobile.com.hk
The IMS APN is not the active "checked" one, but must be present in order for the voice (VoLTE) network to work on top of the data (LTE) network.
Each carrier has specific values that must be programmed. Sometimes Apple and Google will program these settings through their management controls for the major carriers, otherwise they must be inputted manually.

Thank you so much for writing all that out. i bet it's the APN settings. There was only the one for pine and putting the sim in another pine cellular phone had it working. I'm going to try one more time before I send it back. I'm not very confident that pine customer service knows that they are doing at this point.

I guess I'm going to send this phone back and buy something from Pine. Bought a new SIM card from them this morning and it still doesn't work. I now have data roaming on ATT but still no VoLTE or WIFI calling.
The Pine rep I talked to this morning was much better than the previous one and she said she had experienced this previously with a clients new phone. Pine was "old school" with some of their internal system.
I did notice they aren't selling any 5g phones yet so it's possible it's something with this being a 5G phone or maybe Android 11.
