VPN not working with PM cellular data

loch_ness — Fri, 19 Dec 2025 06:56:24 GMT

Hi there,

I’m trying to connect my VPN to PM’s cellular data but it has been unsuccessful. I’ve reserved the APN, deleted the VPN app and re-installed, turned the e-sim on and off and nothing seems to work. Has anyone ever had this issue?

@loch_ness

let's start with make / model of your cellphone.

@loch_ness

first, this is not an PM issue, PM does not actively block VPN and I have been using without issue.

are you using NORD VPN? some seem to have problem with it

What you can do is to change the VPN Protocol on the app from Automatic to OpenVPN - TCP or WinGuard or try other protocol.

do you have an iPhone?

some mentioned it might have to do with IPv6 issue,

but another mentioned the he has NordVPN and it works on iPhone 17 Pro Max but not 16 Pro Max. So, I am not certain it is really a IPv6 problem. But almost certain it has nothing to do with Public Mobile

Yes, I do. I’ve upgraded my phone from iPhone SE to iPhone 17. And it is in fact Nord VPN. Thanks for sharing the thread! Very helpful although I’m not sure if I’ll be able to connect to the VPN now…

That would be me. I reset my network settings on my iPhone 17 Pro Max and bam NordVPN is broken and no longer connects. This isn’t a NordVPN issue but a Public Mobile issue if a simple network setting reset results in me not being able to use my app

Hey @SteveC1 @loch_ness, I had the same issue as you with NordVPN, and the solution was to install a configuration profile to disable IPv6.

I followed the steps here and it fixed it:

First download iMazing profile editor from the Microsoft App Store.

Within iMazing profile editor,

On the left hand pane, select Cellular, press the "+" button on the main pane.
For Data APN, fill in the "Data APN" column with "isp.mb.com". This is the only entry required in this table.
For Default APN name, fill in "isp.mb.com"
For Default APN supported IP versions, select IPv4 only.
As an optional step, on the left hand pane, under General, I updated the Payload Display Name to "public_mobile_disable_ipv6" and updated the Payload Description to "Set APN to isp.mb.com and IPv4 only." On the same page, change Target Device Type to "iPhone/iPod/iPod Touch". This step is just to name the configuration profile and set it for iOS devices only.
Next, press File -> Edit -> Save As. I named the file as "public_mobile_disable_ipv6.mobileconfig". Leave the "Sign profile with" as Do Not Sign as signing is not needed.
Transfer this file to your iPhone. I just uploaded the file to OneDrive and downloaded it using the OneDrive app into my iPhone's Downloads folder.
Open the file and it will say the profile has been downloaded.
On the iPhone, go to Settings -> General -> VPN & Device Management, and click on the new configuration profile. Install it. Your data will turn off and back on, and everything should be working after that.
Do a Google Search for What's my IP and it should only show an IPv4 value only now, and NordVPN should be able to connect again.

My understanding is that doing all these steps effectively disables IPv6 when using the Public Mobile network. I'm not entirely sure if there's any consequence in disabling IPv6, but everything I've tested so far seems to be working fine.
