[Q] Delayed notifications when using VPN on Android - Android Q&A, Help & Troubleshooting

Hi,
A question: I receive delayed notifications on my Android phone (Kitkat 4.4.2) when using PPTP or OpenVPN. Sometimes it takes more than 30 minutes to get a notification when receiving new e-mail or WhatsApp messages. Is there anything i can do about this? Thanks!
I have both PIA and CyberghostVPN. Same problem on both VPN providers.
I am connected to the mobile network (no WiFi)
This happens on all my Android phones.

[Q] Can't connect to mobile network

Hi guys,
I have installed CM7.2 nightly version on my ace, but not I can't stay connected to the mobile network (bell canada).
If I turn the airplane mode on and then off the phone is able to send messages and seems connected, but few time later, it seems disconnect (does not show a message that lost connectivity, just can't receive or make calls or messages).
Does anybody have a clue?
Thanks

MMS issue only while connected to wifi

I'm using the C6806 GPE edition z ultra, bootloader locked and unrooted. I've run into an issue with sending and receiving MMS messages while I am connected to wifi. I am not attempting to send messages over wifi and my APN settings are correct. If my wifi is turned off, I can send and receive without issues. But when it's on, my outgoing mms will sit "sending" forever. Incoming messages come through with the download link but I have to disconnect from wifi to be able to sucessfully download.
I've tried multiple messaging apps and all seem to have the same issue. These are the ones I've tested: Hangouts, EvoleSMS, 8SMS, Textra. Even with the recent update in 8SMS to enable mobile data to send MMS, it still gets stuck in a sending state and is never received by the person I am trying to send to.
Has anyone else had a similar issue or any idea of how to fix it?

Android OpenVPN connected no MMS

I am using the Google Play Nexus 5 on T-Mobile US.
I am running CyanogenMOD 11 Snapshot M9 hammerhead
Android 4.4.4
OpenVPN for Android
DD-WRT Router using the OpenVPN server
I currently have a phone and VPN connection as described above. It connects and works great. The issue I am having, and have searched xda and google for the answer, is that when the VPN is connected everything works fine, except MMS. The APN is correct, per T-Mobile's website. I can send and receive MMS without the VPN connected. The moment I connect to the VPN my MMS in and out fail. I have read on Cisco's website that android has something blocking MMS when connected to VPN.
So, my question is: Is there any way to remove this block or reroute only MMS traffic outside of the VPN? I do have Android Firewall installed, so iptables is usable to do this.
No one has anything for this?
Having the same issue here.

Has anyone ever found a solution/workaround for this? I had this problem on my Galaxy S4 on 5.0.1 and now I'm having the same issue on my S7 on Marshmallow. Thanks!

The only "solution" I found, but did not feel it was the true answer, was just a workaround. I noticed that when I am hooked to wifi as well MMS fail to send and to receive. I just have to turn it off and wait for the message than turn it back on. Sucks I know, but it works.

That's a bummer! My biggest problem is receiving messages. I don't get any notification that it's trying to receive a message so I don't even know one is trying to come in.

I do get these messages, but I am using a third party MMS/SMS client (ChompSMS) that tells me when it is trying to receive something.

I may have found a solution but I still need to do more testing. When looking through the settings of some messaging apps I've noticed some give you a "MMS Behavior" option. In Textra it says:
Code:
Try 'System' if legacy MMS isn't work (for example with Project Fi, VPNs, WiFi MMS, etc).
So I set it to System and so far it seems to be working fine while being connected to my VPN. If I change back to "Legacy" or to a different default messaging app without that option it seems like they stop coming through again.
So far I've only tested this with pictures messages and haven't had a chance to try group texts yet. ChompSMS has the option in there but I've only tested it with Textra. I'm using a Galaxy S7 on Verizon so I'm not sure if that affects anything either.
Well, I tested it in ChompSMS, but no luck.

I would bet this is because the MMS server only allows the carrier IP Range. If it's blocking over Wifi as well that would prove that it's not just VPN that is causing it. I would imagine you could receive MMS from anywhere if you have a way of getting your mobile/carrier IP address. (Some sort of proxy(?))

I haven't used these in a while, but when I did they both worked over wifi. Textra and 8SMS. See if installing either one helps, if not uninstall.
But beware, if your provider doesn't support MMS over wifi you won't be able to use it, here is the warning from 8sms on MMS settings:
MMS over Wifi
If your cellular network (ie. Sprint) supports mms over wifi, you can enable Settings » MMS Settings » MMS over Wifi.
If your cellular network does not support mms over wifi (or you are not sure), then DO NOT enable MMS over Wifi or mms will stop working.

I believe T-Mobile USA does support MMS over wifi

I had issues with having my VPN active and not getting SMS/MMS messages while connected. Went looking for an answer and found that there wasn't any one single solution for it so I thought I'd post what worked for me. FWIW I'm on T-Mobile USA with Android 6.0.1.
Within my VPN configuration I went to the 'Allowed Apps' tab and excluded my SMS/MMS programs and processes. Namely I made sure Textra, Messenger, and MmsService were all excluded from the VPN and this resolved my issue. After disconnecting and reconnecting the VPN my text messages are sent and received without issue.
Was a pain in the butt for me as I have tasker setup to bring my VPN to life whenever it's not connected to my home wifi network. Took me a day or two to notice that text messages weren't going anywhere while the VPN was active. Oddly enough being on my home wifi network along with wifi calling being active has never caused an issue with SMS/MMS not working, but having a VPN active did.
I have switched to the Nexus 6P and am running rooted stock 7.1.1 (beta). Still with T-Mobile. I still have issues with MMS on wifi and on VPN, but no issue with SMS. It is strange. Maybe it is time to ask T-Mobile.

Clarity on mobile network and texts

So have note 4 and gear s
If I leave my phone home how can I receive texts from my phone? Is that possible?
The other night I thought I turned off Bluetooth on phone, and gear and phone maintained some link through the mobile network.... Can't seem to reproduce.
Forwarding my phone to watch is easy... But doesn't help with alerts like texts.
Thanks!
When I leave my note 4 at home the watch switches to the mobile network and connects remotely to the phone.
I still get my texts and calls to the watch from my phone.
As long as you are using the Samsung message app it should link remotely and recieve texts via your Samsung account.
Thanks for the reply. Do you have to leave mobile network on the watch?

Txt messages sent to Gear S phone number only arrive after disconnecting from phone

I only receive text message sent to the phone's number (Google Voice forwarding to the watch phone number) when the device is disconnected from its bluetooth connection to the phone.
This is probably because the watch is connected via Bluetooth to the phone, and not to mobile networks. I thought I read that Samsung had set up special servers to deal with this and other issues?
Is there any way to have txt messages reliably sent directly to the watch when the watch is connected via bluetooth or wifi? (not mobile networks). Or will I have to turn on mobile network connection permanently (battery drain).
(As for why I don't have Google Voice notifications sent to the watch from the phone, it's because they can't be replied to from within the watch while Txt messages can.)
You'll have to have the 4G mobile network turned on all the time. This is the only way that the phone can receive a text sent to it's mobile number. If the Gear S is connected to Bluetooth or wifi then there is no way for the SIM to connect to AT&T's network and receive a text.
Another option may be if you have GV forwarding texts to your phone's mobile number, and you use the default SMS app then the text will be forwarded to the watch when the phone and the watch (Via WiFi) both have a data connection via remote connection.

Thanks. Yes, I'd considered forwarding GV texts to the phone's number, but that kind of defeats the purpose of using GV for texts.
I suppose I could disable the messaging app's notifications on the phone so as not to get double notifications on the phone every time a txt arrives. But would that prevent the watch from getting notifications as well? I'll have to give it at try.
Just switch "Gear Network" under settings to "Always On" rather than "Auto Switch" and it will solve this issue. Putting it to "Always On" will leave your Gear S's cell network connected while paired with your phone over bluetooth.

Yes, I've figured that out, but leaving mobile networks on all the time drains the battery much more quickly.
The best option is probably a custom notifications app that allows response to Google Voice messaging.
