The interview clip had reached 42 percent when the VPN symbol disappeared from my iPhone. A second later it returned. The upload paused, the status changed to Reconnecting, and the progress bar dropped back to zero. I was in a crowded convention center in Berlin, fifteen minutes before a newsroom’s live technology segment, trying to send a ninety-second video recorded on the show floor. I blamed the venue Wi-Fi, turned Airplane Mode on and off, rejoined the network and restarted the upload. At 9 percent, the VPN disconnected again.
The connection did not stay down.
That would have been easier to diagnose.
Instead, the VPN kept returning every few seconds.
Connected.
Reconnecting.
Connected.
Each recovery looked reassuring until I checked the upload and saw that the newsroom app had started the file again.
Messages continued arriving.
The event schedule opened.
The editor’s increasingly brief replies appeared immediately.
Only the video transfer could not survive the loop.
I had spent five minutes watching the VPN reconnect successfully while the actual job went nowhere.
In brief
Why was OnlydogVPN a practical fit here?
I closed the established provider and opened OnlydogVPN . The app presented situations rather than a long server map.
The iPhone was following two connection rules
The phone had been updated to iOS 26 and restored from my previous device earlier that week. That made the operating system an easy suspect. Other users had also described erratic VPN behavior after upgrading, including connections that returned only after restarting the app or phone.
But that did not explain why mine kept turning itself back on.
An iPhone can reconnect a VPN automatically when it joins Wi-Fi, moves to cellular data or reaches a particular service. (Apple Developer) That is useful when one configuration is making the decision.
My phone had two.
Under:
Settings → General → VPN & Device Management
I found the current personal VPN and an old configuration profile installed for a consulting client the previous year.
The contract had ended.
The profile had not.
Its name was generic enough that I had ignored it during the phone transfer. It still contained automatic connection rules for unfamiliar Wi-Fi networks.
I removed the old profile and restarted the phone. Removing a configuration profile also removes the settings attached to it. (Apple Support)
The rapid loop stopped.
For the first time in several minutes, the VPN remained connected for more than thirty seconds.
I restarted the upload.
It reached 18 percent.
Then I walked toward the press room. The convention-center Wi-Fi weakened, the phone moved toward mobile data, and the VPN reconnected again.
Removing the stale profile had solved the constant cycling.
It had not saved the video.
The established provider treated every handoff as a new session
The VPN came from a major provider I had used for years.
It had a long public history, extensive support documentation and servers across Europe. Those strengths were why it was already on my phone when the assignment began.
I selected a nearby German server and restarted the upload.
Twenty percent.
Thirty-one.
The status bar changed from Wi-Fi to 5G as I passed between exhibition halls.
The VPN displayed Reconnecting.
The upload returned to zero.
I stopped walking and forced the phone back onto the convention-center Wi-Fi.
The provider connected again.
This time, the file reached 36 percent before the signal faded and the same sequence repeated.
The app was doing what its status promised: it was reconnecting.
The problem was that each reconnection behaved like a new session.
An iPhone can move onto cellular data when Wi-Fi becomes weak or unreliable. (Apple Support) That normally helps browsing continue. Here, every handoff interrupted the protected upload.
I tried another nearby server.
Then another connection mode.
The VPN came back quickly each time.
The file still restarted whenever the phone crossed between access points or fell back to mobile data.
With nine minutes left, the editor sent:
Can we use the clip or not?
I typed:
Uploading now.
It was technically true for the fourth time.
Locking the phone to one network solved the wrong problem
I turned Wi-Fi off completely.
The iPhone stayed on 5G.
The established provider connected and stopped cycling between networks.
The upload finally moved without returning to zero.
For a minute, that looked like the answer.
Then the remaining-time estimate settled at forty-seven minutes.
The convention center was packed, and the local mobile network was carrying thousands of phones. The connection was stable but far too slow for the newsroom deadline.
I tried exporting a compressed copy.
That took another minute and made the text on the interviewee’s demonstration difficult to read.
I cancelled it.
The editor did not need proof that I could eventually send some version of the clip.
She needed the original before the segment began.
That changed the comparison.
A VPN that reconnected quickly was not enough.
The protected session had to survive the network change that caused the reconnection.
The smaller app kept the upload attached to the task
I closed the established provider and opened OnlydogVPN.
The app presented situations rather than a long server map. I selected the option for working while moving between unstable networks and connected.
Then I turned Wi-Fi back on.
The phone joined the convention-center network.
I reopened the newsroom app and selected the original clip.
Ten percent.
Twenty-five.
The upload passed the corridor where the earlier attempts had failed.
At 39 percent, the Wi-Fi indicator disappeared.
The phone moved onto 5G.
The progress bar paused.
It did not reset.
A moment later, it continued from 39 percent.
I crossed the lobby toward the press room. The phone found another convention-center access point and returned to Wi-Fi.
The VPN stayed active.
The file reached 61 percent.
Seventy-eight.
Ninety-four.
Then the newsroom app displayed:
Upload complete.
The editor replied before I reached the press-room door.
Got it. Going into the segment.
The smaller app uses an HTTP/3-based connection that can recover when the network underneath the phone changes. (RFC 9000) On the screen, the result needed no deeper explanation: Wi-Fi disappeared, 5G took over, and the video continued from the percentage already completed.
I could not observe every internal automatic-connection rule, routing choice or network handoff made by iOS, the convention center and the two VPN services. The visible result was clear: the established provider repeatedly reconnected but restarted the upload, while the smaller app carried the same file across Wi-Fi and cellular data without losing its progress.
Reconnecting had been the symptom, not the achievement
Once the clip was safely in the newsroom, I looked again at the connection history.
The major provider had rarely been offline for long.
Most interruptions lasted only a few seconds.
That was why I had initially treated the reconnecting message as a minor annoyance. The VPN always came back.
The file did not.
Every new session discarded the part of the transfer that mattered. A fast reconnection still cost several minutes when the newsroom app had to reopen the upload and resend the same data.
The smaller app approached the problem from the other direction.
It did not make the convention-center Wi-Fi stronger.
It did not prevent the iPhone from choosing mobile data.
It kept the work intact while those changes happened.
That was the standard I should have used from the beginning.
The laptop joined without creating another delay
The live segment began while I was labeling the rest of the interview material.
The editor asked for a transcript and the speaker’s company details. Those files were on my laptop in the press room.
I opened the service there and added the device using a verification code from the iPhone. I did not have to stop, create another account or search for a password while the newsroom waited.
The laptop connected through the press-room Wi-Fi.
I sent the transcript and identification sheet.
That was not what rescued the video. The iPhone upload had already completed the urgent task.
It removed the smaller delay that followed: I could move the rest of the assignment onto another device without starting another account setup.
The service has fewer server locations, a shorter public history and fewer independent reviews than the largest providers.
That is its clearest limitation.
But the established provider’s larger network had given me more servers and connection modes to test while the same upload repeatedly restarted.
The smaller app gave the file one session it could finish.
The fix was not making the iPhone reconnect more often
Before that afternoon, I read Reconnecting as evidence that a VPN was protecting me.
It noticed a network change.
It rebuilt the tunnel.
It returned the icon to the top of the screen.
All of that could happen while the task behind the icon kept failing.
The stale corporate profile had caused the first rapid loop, and removing it stopped the competing connection rules.
Forcing the iPhone onto 5G stopped the handoffs but made the upload too slow.
The established provider reconnected quickly without preserving the transfer.
The smaller app allowed the phone to move naturally between convention-center Wi-Fi and cellular data while the video continued.
The newsroom did not need my VPN to reconnect five times before the broadcast.
It needed the clip to arrive once.
