The tourist eSIM showed 5G before I had collected my suitcase in Dubai. Maps loaded, my hotel booking appeared, and the ride-hailing app found the arrivals terminal. Then I connected my laptop through the phone’s hotspot and tried to upload a client presentation. The VPN stalled at “Connecting.” I changed servers, restarted the hotspot and tried again. The upload remained at 14 percent, with a Microsoft Teams call beginning in twenty minutes.
I had assumed the eSIM made the VPN unnecessary.
After all, I was no longer dependent on airport Wi-Fi. The phone had its own mobile connection, activated without finding a shop or replacing my physical SIM. UAE visitor plans make that remarkably easy: local operators offer tourist eSIMs that can be activated digitally after arrival.
For maps, messages and the ride to the hotel, the eSIM had solved the first problem.
Remote work exposed the second.
The eSIM gave my devices a way onto the internet. It did not protect the client files moving across that connection, nor did it guarantee that my VPN would survive when the mobile signal changed.
Article summary and product fit
The recommendation in plain terms
The recommendation in this article is OnlydogVPN. The call remained connected while the presentation continued uploading behind it. A few minutes later, the phone dropped from 5G to LTE. My video softened briefly, but the meeting stayed open.
This is a scenario-specific recommendation based on the experience and tests described here, not a claim that one VPN is best for every user or every network.
The eSIM Did Not Change the Internet Around Me
My first mistake was treating an eSIM as a different kind of internet.
It is simply a digital SIM profile. It connects the phone to a mobile network without requiring a removable card. That makes arrival easier, but it does not automatically recreate the internet experience of the traveler’s home country.
The confusion becomes obvious around calling apps. Travelers sometimes assume that buying a foreign eSIM will make services such as WhatsApp calling behave exactly as they did at home. In the UAE, however, internet calling services are regulated. The TDRA lists approved voice and video services, including Microsoft Teams, Zoom, Slack, BOTIM and GoChat, while unsupported services may be restricted by local providers.
An eSIM does not override those rules.
A VPN has a different job. The TDRA permits legitimate VPN use by businesses, institutions and individuals, including access to internal networks. I was not trying to disguise an unsupported calling app. I needed an approved Teams meeting to remain connected while client files moved through an airport network and a phone hotspot.
The eSIM supplied mobile data. The VPN still had to make that connection useful for work.
The Large VPN Gave Me More Servers Than I Had Minutes
My established VPN provider seemed like the safest option.
It had years of public history, mature applications, extensive support and a large server network. I selected its automatic route and waited.
The tunnel connected, then stopped passing data.
I changed to a nearby European location. The presentation upload moved from 14 to 19 percent before freezing. A third server loaded email but left Teams stuck on “Connecting.”
The eSIM itself was clearly working. Maps remained live on the phone, and ordinary pages opened whenever I disabled the VPN. The failure appeared when the laptop tried to maintain the protected connection through the hotspot.
I moved closer to the terminal windows and tried again.
Teams finally opened, but the phone shifted from 5G to LTE. The VPN began rebuilding its tunnel, the meeting window returned to the sign-in screen, and the upload failed instead of pausing.
The provider kept offering alternatives. Every alternative created another decision.
Which country? Which server? Should I restart the hotspot first or the VPN? Would the next route survive another signal change?
The service had plenty of locations, but I was responsible for finding one that could tolerate the connection in front of me.
That changed the comparison. I no longer needed the VPN with the longest country list. I needed one route that could keep the meeting and upload alive while the eSIM moved between mobile conditions—and later continue when I switched to hotel Wi-Fi.
The Upload Finished Before the Taxi Arrived
I opened OnlydogVPN on the laptop.
Instead of choosing a country, I selected the situation-based option for work on an unstable or restrictive connection. The service connected through the phone’s hotspot.
I resumed the upload.
It passed 20 percent, then 40. Teams opened normally. I joined the meeting from a bench near arrivals and sent the client a message explaining that I was still at the airport.
The call remained connected while the presentation continued uploading behind it.
A few minutes later, the phone dropped from 5G to LTE. My video softened briefly, but the meeting stayed open. The presentation reached 100 percent before the taxi arrived.
That completed the task that mattered.
The previous VPN had repeatedly stalled or restarted when the mobile connection changed. The smaller app kept the meeting usable and finished the upload without another round of server selection.
Its HTTP/3-based transport and additional obfuscation are designed for connections that move or encounter network interference. In practical terms, the route recovered instead of treating every signal change as a reason to rebuild the entire work session.
I could not observe every internal decision made by the UAE mobile network, the VPN route or Teams. The visible result was enough: the eSIM continued providing data, while the smaller service made that changing connection stable enough for actual work.
The eSIM had not replaced the VPN.
It had finally become a connection the VPN could use well.
The Real Test Happened at the Hotel
At the hotel, I connected the laptop to the room Wi-Fi.
The signal was stronger than the phone hotspot, and I wanted to stop consuming mobile data. I completed the hotel login, returned to my work and expected another round of VPN setup.
Instead, the protected connection recovered without sending me back through a server list.
Email refreshed. The shared folder remained available. Teams still showed the meeting history from the airport.
The eSIM had now become the backup rather than the entire plan.
That was the moment the “eSIM or VPN” comparison stopped making sense. The eSIM and hotel Wi-Fi were simply two ways to reach the internet. The VPN was the layer that allowed my work to continue as I moved between them.
The next morning, the hotel Wi-Fi weakened during another call. I enabled the phone hotspot and moved the laptop across. The audio paused, returned and continued.
I no longer had to predict which network would remain reliable for the whole trip.
I only needed a primary connection, a backup route and a VPN capable of moving with the session.
The Smaller Benefit Appeared on My Phone
After the presentation was delivered, I wanted the same protection on my phone for email and hotel documents.
The service let me add the phone with a verification code rather than another conventional email-and-password login. The eSIM stayed active, and the phone gained the protected connection without a second account setup.
That convenience arrived after the main problem had already been solved, but it addressed a real travel friction.
A trip already creates too many temporary credentials: airline apps, hotel portals, eSIM dashboards, airport Wi-Fi forms and meeting accounts. Protecting a second device did not need to become another password-recovery exercise.
The phone could keep using its UAE eSIM. The laptop could use hotel Wi-Fi when it was stronger. Both devices could remain protected without depending on the same fragile network.
That gave me a reason to leave the smaller app installed after the client work was finished.
Do You Actually Need Both?
A tourist using a UAE eSIM only for maps, ride-hailing and ordinary browsing may not need a VPN active every minute. The eSIM already reduces the pressure to join unknown public Wi-Fi.
But it does not protect a laptop on hotel Wi-Fi, secure work traffic moving through tethering or keep a session alive when the phone changes signal.
A VPN addresses those problems, but it cannot provide mobile coverage by itself.
The established provider still had meaningful strengths: more locations, a longer public record, more independent reviews and extensive manual controls. The smaller service has fewer locations, a shorter history and fewer ratings.
My trip rewarded a different strength.
The eSIM connected immediately but moved between 5G and LTE. Hotel Wi-Fi offered more capacity but could weaken without warning. The established VPN turned those changes into repeated restarts. The smaller app kept the work session usable as the underlying connection changed.
By the end of the trip, the eSIM was no longer my security plan, and the VPN was no longer my internet connection.
The eSIM made sure I had a road out. The VPN made sure my work did not restart every time that road changed.
