Custom map for GSM operators - Android Q&A, Help & Troubleshooting

I installed 15 different apps, still no luck.
I need to know which is the strongest operator in my home... but without subscribing ALL operators just for testing!
I can't find an app capable of mapping all operators.
BUT:
1) I'm sure my phone can see all available operators: I can see them when selecting "manual operator selection" option.
2) I'm also sure my phone can see the signal strength of at least one operator: when I have no coverage from mine, I can anyway see the signal strength icon changing.
3) I'm sure any app on my non-rooted phone can read MNC code of the closest base station, and MNC identifies the operator.
Is there any app capable of collecting all these data and thus allowing me to build MY OWN map (not just a downloaded map) of operators coverage for MY specific phone?
I don't know if 1) and 2) info are available to apps, but even an app just using info 3) would be very useful to me.

[Q] How to enable 3G on Viewpad 7

I have recently purchased a viewpad 7. I have also enabled 3G services from my operator. Can somebody help me in the following:-
(a) How to start a video call?
(b) What will be the indication for 3G services running on the pad?
(c) Can someone show me a display of the screen with 3G services enabled?
What is your mobile operator (and country, if applicable) since we have users around the globe on this sub-forum?
Based in US, I've used a prepaid 3G Sim from AT&T (also, tested my China Mobile HK/China dual phone # prepaid Sim) and getting E(dge) or 2G+ voice/data services only along with much faster secured wifi (20GB broadband) - but I'm setup to use Google Voice for all voice calls.
Regardless, the upper right portion of the status bar (on top of the display) should show the "H" or "3G" symbol when data is active.
Try by going to Settings, Wireless & network settings and check your Mobile networks - check that Data is enabled (including roaming, if applicable) and that Network Mode is configured properly, also APN is set for MMS per your mobile operator specifications, etc. etc.
I'm doubtfull about its ability to easily take/make video calls over mobile network (possible & probably easier to configure over wifi - with the proper software as bandwidth needed could be part of the issues) - however, I could be mistaken & not fully up-to-date on this.
I am using BSNL network India. In the mobile network settings on enabling data, the download E symbol shows up on the top right with arrow marks. I am able to load/upload data but no video calls. The review says that video calls are possible with the viewpad 7. But how please help.....
view this thread i have just run into the same problem
http://forum.xda-developers.com/showthread.php?t=1267297
and there is the solution, if you have a different network, pm me ill work out the solution for you
note im with o2 in the uk, as for your other questions, to indicate you have a 3g signal, there will be a 3g icon next to the signal bar, in my case its a H as im connected to a HSDPA signal.
I put my automatically: S

DOes it mean, your VP7 can not connect to internet via mobile/SIM module? I had the same problem with the latest official ROM from VS. I Had to install FM6-3350-0-1008-A01.nb0 which I have to find on this forum. Unfortunately I have lost Czech localization.

select a network operator based on mcc

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:

Anyone using this phone with AT&T in the US?

I love this phone....there, I said it. But it's driving me crazy.
I bought it from a Chinese retailer, who shipped it with X821 firmware, but the box states that it's an X820. I doubt there is any difference in the hardware.
I would have left everything as it was, but I can't seem to make phone calls (don't have a data plan yet...yeah, I know....) with anything other than 2G, and that is about to go extinct. When I set it to WCDMA, it shows a UMTS connection, with no carrier designation, but the tower is the same one I connect to with 2G. The phone does sometimes show an AT&T 3G connection in the status bar, but I can't make calls, even though I have full signal. When I place the same SIM in my old HTC Inspire, the same monitoring app shows "UMTS - AT&T HSDPA+" and works just fine.
I'm at my wits end. I have rooted, installed TeamSpain recovery, replaced the firmware with the X829 and even tinkered with the frequency configurations through DFS Studio (which did a lot of complaining, and I'm still not sure if the changes stuck 100%). I also played with APN settings and tried the SIM in different slots, both alone, and with another SIM. And after all of that, still no progress in getting this phone to use a 3G or 4G connection to make calls. If I don't set it to "GSM only", no phone calls in or out. I'm essentially right under a tower, so signal shouldn't be an issue.
If anyone is using the same provider in the US, and is not having these kinds of issues, I'd really appreciate hearing what firmware you are using, and/or what you did to get things working.
I am using it on x820 with official stock 0.17s firmware, and did a dirty flash to cuoco92's 17s firmware. Everything works including HD voice calls, and full LTE.

I tried this, as well as the Remix ROM. In fact, I think I've tried just about everything, without success. At one point, I had one of the apps indicating a 4G connection, but the phone diagnostics showed GSM (2G). Even the apps aren't all sure what to make of what's going on with the connections reported by this phone.
Currently on the cuoco92 v35 ROM. When WCDMA is enabled, I see simply a good UMTS connection , sans carrier name, in the "Network Cell Info Lite" app, and no ability to make calls. I also often (but not always) see the "AT&T 3G" sign. 4G or LTE never shows at all, even though the diagnostics show that the phone is communicating with an LTE transmitter, when preferred network is set to "unknown". It won't even let me set things like "LTE only".
Any chance you could set your phone to WCDMA and see what the "Network Cell Info Lite" app shows you? Anyone else with this phone on AT&T?
BTW, I am now using a data plan, which I thought might make a difference. It doesn't. EDGE data only for me . New SIM card is on the way, but my hopes aren't high.
Is it possible for a Chinese seller to have borked the phone so thoroughly with their x821 ROM (it's an x820 marked phone), that it keeps any subsequent radios from flashing properly? I don't know how/why it would work for some and not others.
Starting to really dislike this "phone"......it's more of tablet at this point.
Thanks.
I think APN is not set for AT&T
try this:
"Main steps
To use data services on our network with a non-AT&T device, you may need to program the data settings. The sections below provide the correct settings and steps for programming based on your device type and operating system.
.
Access the Settings menu.
Locate and select Wireless & Networks or More Networks.
Select Mobile Networks.
Select Access Point Names.
Locate and select the option to add a new APN. This is usually accessed by a + symbol on the screen or by tapping the menu button.
Program each field using the settings below.
Save the changes to return to the APNs menu and select the new APN.
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC
MMS proxy
MMS port
MCC 310
MNC 410
Authentication Type None
APN type default
APN protocol IPv4
Bearer Unspecified
Note: If you are unable to program your device following the steps above, refer to your user manual or contact the manufacturer for assistance."

Thanks, but I wish it were so simple. I have tried this, and other APN settings. None work to get this phone to be usable on anything other than 2G.
I just received and activated the replacement SIM. Still no improvement. While typing this, I have Network Cell Info Lite app running, and with the Set Preferred Network Type showing "Unknown" in the phone's diagnostic screen, It will switch randomly between "EDGE AT&T" (which works fine) and "UMTS -" (which is useless). Both have strong signals. For a split second before it switched to "UMTS-", the app showed "GPRS AT&T", but only for a split second before it kicks over to "UMTS-".
I wish someone using this "phone" on AT&T in the US, would run this app to compare notes. It may be that that the phone works fine on a full implementation of LTE (i.e. in locations where AT&T have already deprecated 2G) but not in other areas. Still, that doesn't seem to explain why this phone seems unable to register on the same 3G network, used easily by my other phone, with the very same APN settings and SIM.
You would have to call att and check if they turned our phone on to use lte. If your phone is not "registered" as an LTE capable phone it wouldn't be able to pick it up. This phone has all the bands needed for AT&T because I am using it now. All LTE work straight out the box, and i'm on the latest 19s cn rom

I'm a bit confused. Is this what you did to achieve proper function of this device? I.e. calling AT&T and getting them to do this for you? My conversation with their tech person didn't seem to bear fruit in this regard.
Also, which slot do you have the SIM card in? I've used the stock 17s and now on cuoco92 v35 ROM. There definitely seems to be a difference in how the network settings behave, based on the location of the SIM. At one point, after selecting BAND 6 (when it would let me), the phone showed a constant "AT&T 3G" connection, but it was useless. No calls and no data.

H961N Network Issue

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.

Choosing preferred cellular operator

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 ...
