Hey all! I've tried googling/searching XDA, but I must have my terms wrong or no one is talking about it.
Question: Is there a way to restrict which mobile networks my phone will connect to?
Device: Google Nexus 5 32gb, Stock Rom/Kernel with Root access
I'm switching to a T-Mobile Simple Choice plan with free 2g data in 100 countries, and going on a cruise shortly after. A couple of the ports of call are on the list, while others are not on the list. It sure would be nice to just leave my phone on and have it only connect to the free networks. I contracted T-Mobile and was pointed to a document letting me know that I will be notified if charges are incurred, but I'd rather not get charged at all. This I could solve manually by carrying the list of countries with me and only turning off airplane when I am there, but that does seem like a pain to me.
The other problem, cruise ships have cell networks onboard now. These networks are charged as international and not included in the Simple Choice deal. Even if I am in port, I am concerned I may still connect to this netowork. I imagine there is an app I could use to at least see which network I am on (I can't find it indicated in Settings anywhere - probably blind), but I would need to prevent my phone from roaming onto that network when both are in range.
I'd really appreciate any thoughts/suggestions. The only thing I can think of is some kind of custom block that would like me restrict network connections. All way over my head.
Thanks again
Matt
You're going to have to manually select them. I'd turn data roaming off until you get some where you know you can turn it on. Also, most port of calls have Wi-Fi and I'd use that where you can. You can often even get it on the ship at a port, although you might have to find the right location on the ship where you can do that.

Thanks for the tip about Wi-Fi networks. Absolutely. Unfortunately, I'm not even sure how to manually select the network to which my phone connects. Any advice on where/how to select that?

Hello,
I'm having trouble using my phone in roaming. My home mobile provider is Vip net., in Croatia. I'm currently in England, and my phone is currently connected to Vodafone network, which a partner of Vip.
I'm unable to get mobile data connection unless I'm connected to Vodafone 4G network. When I do a manual scan of networks, I can see (most of the time) three instances of each network (4G/WCDMA/GSM). Whenever my phone decides to switch from 4G to WCDMA or GSM, I lose the mobile connection.
APN is of course set correctly since otherwise I wouldn't be able to connect to the network on 4G (I've even had my provider send me the APN configuration message to make sure that's correct - I also tried various modifications to settings of the same).
I've talked with my providers technical support and they haven't been able to provide me with a solution, so I'm wondering if anyone here might have a clue about what is happening?
I've tried doing some basic diagnostic with adb, but haven't been able to gather much from modem logs, which I've attached here, and I would be grateful if anyone would take a look.
Here is the log, please note that it starts with me turning on mobile data and ends with me turning it off:

The phone in question is LG G5, Android 7.0 Nougat, Stock rom. (I had the same issue on 6.0)
Thanks guys!
Hello,
Does anyone know what I can do to lock my OnePlus 7 pro to T-Mobile? I live quite close to Canada and the phone always tries to connect to Rodgers or Bell. I tried going into mobile networks and unchecking the box to automatically choose a network operator and selecting TMobile, but it still tries to roam and I get no service.
After some research, I see there's an app that may help me: Network Signal Guru. It requires root, and I don't really want to go this route unless I have no other option.
Thanks in advance

Can't you go into the phone settings and turn off roaming?.
Open the phone app, three dots at the top, settings, all the way at the bottom, Sim and Network, Sim 1, turn off roaming in there.

If I do that then I'm in the same situation with no bars, no data. I need to force it to connect to TMobile

Go to sim and network, tap on the sim you are using. Scroll all the way down, tap on Network operator, disable the option to choose automatically, it will scan for available networks, choose T-Mobile. Leave the option disabled. it should be it.
I have the one plus 8 uw from Verizon. I cannot for the life of me get this device to connect to a 5g network nor my 5ghtz router. Is there something I'm missing. I have changed my plan, reset network settings and even tried safe mode on the device. I'm in a 5g area as another device can connect sitting next to me.
Try going into settings, Mobile hotspot, find wifi 6 standard hotspot an try either enabling or disabling it.
Hey guys, I’ve recently entered the android headunit world and purchased a android 10, 10.1” joying headunit (octa-core 1.8ghz, 6gb ram 720p).
The headunit is fantastic and exceeds my expectations in every way, except the 4G mobile data function doesn’t work.
I’m from Aus, so I’m using a verified working 4g mobile broadband Telstra sim that is a GSM type (which joying says is compatible).
The unit detects the SIM as it should, identifies it as a Telstra sim, shows full 4G signal in the top bar however it has no data stream.
I have the mobile data function enabled, roaming enabled, no data saving features turned on and have made sure to set all my apps to unrestricted access.
The interesting thing is, if I turn the headunits hotspot feature on, and use the units 4g network as a hotspot and connect my phone to it, everything works perfectly and it shows a perfect data stream.
However the unit itself cannot use its own data.
I have followed all of the instructions given here:
Android car stereo, Android 10.0 Head unit
How to solve the 4G problem on Joyin --> How to solve the 4G problem on Joying head unit? Following ideas are for solving the 4G problem when there i
www.joyingauto.com
But seeing as how the unit can actively stream 4g data via the hotspot function, there doesn’t seem to be an issue with SIM card settings or anything hardware related.
Has anyone come across this or have any idea what I should do next?
(Let me know if you need any unit details)
I don't know if this will help because you said your hotspot works but have you checked your APN (access point names) settings to see if there are two options to switch between?
There was only one in there which was the default automatic setting. But I figured that if the headunit could still send and receive data via hot spot to another device that the APN must have been correct?

Yeah, that's what I would have figured too. But I'm not an expert. Is there a DNS setting you could change? Perhaps add a custom DNS hostname such as dns.quad9.net ? I'm just guessing here.
I’ll have another look tonight but I don’t remember seeing any settings to change the DNS host name.
I was able to hotspot data just fine however the headunit had no internet.
Verify that the acces point names (APN) are set correctly. I had to copy the settings from my phone (using telstra) and apply them to the headunit.
This can be done by going to Mobile Networks > Access Point Names > [first one in list]
I had to change APN to telstra.wap and APN Protocol to IPv6. Also, there's a bug where the text is white on the input box. Have to select it to read it.
This worked with both the newer Android 10 (universal 10.1") and older Android 8 (Honda acord kit) on telstra data sims
Absolute legend, thanks mate.
I’ll try that tomorrow and see how it goes!
Thought I’d let you know it worked a dream, just had to change the apn and the protocols.
Thanks again!
I ordered a JY-UQD11N6G about 10 months ago and since then I have tried EVERYTHING that has been suggested here and by Joying. I've tried the universal build from FYT from this very informative post. The head unit recognizes the SIM and properly populates the APN data, but for some reason the time on the device sets back to the build time and date of the ROM every time the device reboots. I have also deleted the prepopulated APNs and created a new APN according the information on my phone when the SIM is inserted and functional which corresponds to the information here.
It does get (or keep) the right time zone, but it will not keep a persistent time through a reboot with a consistent power source.
Joying has sent me an unreleased ROM that doesn't fix the issue. I've tried different external antennae and I've torn the device apart to ensure that the internal antennae are properly soldered to the carrier board (they are). At this point I'm tired of paying $30/mo for a line I can't use.
I just noticed two one pixel wide green lines vertically traversing the LCD, but before I request a warranted replacement, is there anything else I should try?
I tried 4 different SIM cards. T-Mobile pre-paid didn’t word. The head unit recognized the card and everything looked right but no data. T-Mobile post-paid card taken straight out of a display phone in the store worked perfectly, but the cheapest plan was $40/month, and that’s too much. The Verizon card I took out of my iPad and tried did the same as the pre-paid T-Mobile card.
The 4th one I got is from Mint Mobile. Since they use the T-Mobile network, I thought it was worth risking $45. From their website I bought a SIM card with the 4GB phone plan at $15/month for 3 months. It works perfectly! After 3 months I can renew the plan for 12 months and stay at $15/month. 4GB is more data than I will ever use in a month just streaming my music, navigating and doing a few other things, like checking weather/weather radar.
Go with Mint Mobile. It may fix your data issues.

I tried Mint and had the same positive experience, and a Visible (Verizon mvno) card did not work.
But it had bars and showed me an lte connection, it just didn't give me any data. Apn settings were blank, but also wouldn't let me change them, oddly. I'd like to try again as I'm sitting on a visible sim for the next two months that would be cool to use but wondering why some carriers work and others don't, even if they are the same carrier (mvno vs non)?
I have Verizon working on mine, you have to add the APN settings manually via an app from the playstore. However....the device is unknown to verizon so they keep adding it as a phone to my account....for like $50+ a month...I told them i just want data and it should be classified as a connected device.

what provider? what are they charging you for on your account (device type)?
I haven’t used the data service for a while since I started just using apple car play, however my Carrier was Telstra (Australia) and it was something like $15 a month for a
2 GB 4g data sim.
At least as far as I can remember, it did have a mobile number associated with it so I think they were classifying it as a phone plan.

What’s the APN app you got from play store?
I used an app called AddAPN on the Playstore for my Joying and it worked well.
AddAPN - Access the Add APN se - Apps on Google Play
Brings up the Add APN page directly without going through settings
play.google.com
Because the settings app doesnt allow access to edit them...the app edits the apn information since the stock settings app doesnt allow this for some strange reason..
