Unbreakable VPN Connection by Combining Starlink, Wi-Fi, 4G, 5G, and DSL with Speedify
As we explained in a previous post, a VPN is software that encrypts everything you do online. A VPN for mobility, surprisingly is NOT a VPN running on a mobile phone.
In the now classic book Mobile VPN they say the key is “uninterrupted connectivity or the ability to stay connected and communicate to a possibly remote data network while changing the network access medium or points of attachment”.
So, a VPN for Mobility is a VPN which lets you change from one internet connection to another while maintaining the same session and not interrupting all of your apps. This means you can switch from Wi-Fi to Cellular without having your streaming music stop.
Many companies have gotten the older, conventional desktop VPN software (OpenVPN, IKEv2 or IPSec) to work on phones. But these protocols aren’t made for mobile users.
Speedify delivers an unbreakable VPN connection by intelligently bonding multiple internet sources, ensuring continuous uptime and encrypted protection.
Should you have a backup 4G, 5G, Starlink, or cable internet connection?
Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.
4G/5G cellular
Works anywhere. Just a SIM or hotspot — no installation needed.

Best for fixed locations. Different network, so outages rarely overlap.
Learn more →Second Starlink
Adds redundancy and throughput for remote sites or heavy usage.

- We joined a Wi-Fi hotspot,
- Connected the VPN,
- Ran a Speedtest.net speed test, and
- Pulled the Ethernet cable from the Wi-Fi router while the test was still going on.
This is a simple test, to see how where ideally the VPN would just switch to cellular data, or at least disconnect and reconnect on mobile data after a few moments pause.
There are two possible results for this test, that are summarized in the “Maintain Connections” column:
- Yes – Means it switched from WiFi to cellular without needing to change IP addresses or stop a Speed Test in progress (Best!)
- No – Indicates that the VPN stopped working when the WiFi failed, and never recovered, without the user either quitting the Wi-Fi or going back into the VPN app to disconnect and reconnect (Bad)
If we know what protocol the VPN uses, we added it to the Protocol column, as well.
The Results
| VPN Top 10 App Store | Maintain Connection | Comments | Protocols |
| Speedify | Yes | Yanked the ethernet to the router so it was on a “dead hotspot” in the middle of the Speedtest and Speedify recovered almost immediately and successfully finished the speed test. See here a recent video of how it works in the context of live streaming. | VPN for Mobility |

That’s the power of the VPN for Mobility. All the conventional VPNs just stop working when they hit a bad Wi-Fi hotspot, and take you off the Internet. This might be tolerable on a desktop computer, but it’s certainly not acceptable for someone walking around with a mobile phone, roaming from a hotspot to another.
Only Speedify is a true next generation VPN for Mobility that can keep you online even when your Wi-Fi stops working.
