Does Android support Multi-APN function in UMTS network?
which means the mobile phone activate two (or more) primary PDP contexts belong to different APNs.
for instance, in LTE networks, for IMS based VoLTE, it's pretty common for two primary PDPs
one for SIP signaling and another for voice.
but is it possible for UMTS network?
when you downloading via "internet" APN, an APP tries to activate another PDP by APN "wap"
will the "inernet" PDP context been deactivated or not?

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:
Hi,
I have a samsung s3 with cyanogenmod 13. I can't use the data connection since I use a new sim of a italian MVNO.
The data connection is only allowed in 3g but I've set all the settings of frequency band, APN and roaming so I can't understand what's not working in it.
Please help me!
Check apn settings and check cyanogen and the phone are capable

Hi all,
This is a strange problem I don't find anywhere. In summary, I cannot create or modify APNS. This is the relevant information:
- I have a Pocophone Global version with MIUI 10.1.3.0.
- I'm using a Lebara UK SIM card with an active data plan.
- Data are available when in the UK but not when roaming in Europe (Spain in particular)
- Data are available with a different phone and the same SIM card and plan.
- It only does not work with the pocophone.
- All solutions I see are to add a new APN with the right configuration.
- In my pocophone there are two APN set by default, and none of they work when roaming (Vodafone UK and Vodafone UK Prepay). The configuration seems fine, although the APN type is set to "default,supl,mms"
- I CANNOT modify the existing APNs.
- I CANNOT create a new APN.
- In the APNs menu the only option is to "Reset to default" but there is no "New APN". I can see the "New APN" button when using a different SIM card, from a different company.
- With other SIM cards in my pocophone I can actually create or modify APNs. In that case I can create or modify APNs, but not with the Lebara UK SIM card.
The only solution Lebara is suggesting is to create a new APN with the correct settings, but I cannot do that in my pocophone. I would really appreciate if someone has some clue on how to deal with it, or if there is an alternative way to create APNs.
Thank you very much to everyone in advance.
Cheers.
U mean data roaming?
go setting ==> Sim cards & mobile networks ==> Data roaming ==> Never to Always.

Thank you for your answer. Yes, I meant data roaming. The setting you mention is already set to "Always". In fact, I did that before leaving the UK, as someone recommended some time ago.
I have tried to link snapshots of the current APN configuration in this post but I can't because I'm new to this forum. These are some of the relevant APN parameters in Edit access point (that cannot be modified):
Name: Vodafone UK Prepay
APN: pp.vodafone.co.uk
Proxy, Port: Not set
username, password: wap
Authentication type: Not set
APN type: default,supl,mms
APN protocol: IPv4/IPv6
APN enable/disable: APN enabled
MVNO type: None
I cannot change it, and also I cannot add a new one (the button Add new APN does not exist when this card is inserted, so something seems to be blocked in the phone?). Also, the Preferred network type is set to "Prefer LTE", although I also tried "Prefer 3G" and "2G only (saves battery).
Thank you again.
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 ...
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.

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.
