To reduce latency in mobile networks, send game and call traffic over more than one internet connection at once, so a delay on one network does not hold up your packets. Speedify is an app that combines Wi-Fi, 4G/5G cellular, Ethernet, Starlink and satellite internet connections, and its Redundant Mode sends every packet over all of them so the fastest copy wins. On a single connection there is no second copy to race, so Speedify works as an encrypted VPN and cannot lower that connection’s ping.
If your ping jumps around on 4G/5G cellular, you are not the only one: cellular networks delay packets at random. Here is the real-world test showing how much Speedify cut ping times.
Speedify makes your internet faster without a new plan or new hardware
How do I use WiFi and 4G/5G cellular at the same time with Speedify?
Pick your two internet connections and your device below and we'll take you to the step-by-step setup guide.
Testing Whether Redundant Mode Lowers Ping Times
Redundant Mode is a Speedify setting that sends a copy of each packet over every connection you have. Users have been writing in to say it steadied their calls and games, so this test looks at what is happening under the hood.
The obvious question is whether such a system can really improve ping times. If ping is essentially a measure of the speed of light, you might expect little difference from sending duplicate packets in parallel.
Ping Times on Two 4G Connections without Speedify
Here are real ping times from two 4G wireless cards in the Speedify office, first without Speedify at all.
Verizon 4G MiFi
Ping statistics for 74.125.29.147:
Packets: Sent = 47, Received = 47, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 56ms, Maximum = 411ms, Average = 120ms
Clear 4G USB modem
Ping statistics for 74.125.29.105:
Packets: Sent = 45, Received = 45, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 68ms, Maximum = 388ms, Average = 125ms
While there is a clear minimum ping time, there isn’t really a limit on the maximum ping time. 4G cards have ping times around 50 ms when everything works well, but sometimes they randomly delay packets by hundreds of milliseconds!
Ping Times on the Same Two 4G Connections with Speedify Redundant Mode
Next, the same two connections run through Speedify with Redundant Mode selected, and the pings run again. In Redundant Mode, each ping is sent on both connections, and whichever copy gets through first is the one delivered. The results:
Clear 4G + MiFi 4G through Speedify Redundant Mode:
Ping statistics for 74.125.29.103:
Packets: Sent = 41, Received = 41, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 52ms, Maximum = 106ms, Average = 69ms
Average ping drops from 120 ms and 125 ms on each connection alone to 69 ms through Speedify, about 42% lower. The maximum ping falls even more, from around 400 ms to 106 ms, and those spikes are the lag you notice in games and calls.
In this case, Speedify’s Redundant Mode delivers because 4G networks suffer from jitter (variable latency). There are other scenarios where Speedify helps, too: packet loss, and of course, networks losing connectivity altogether.
So next time you load up Battlefield or trade stocks online, try it: download Speedify, connect two internet connections such as Wi-Fi and your phone’s 4G/5G cellular, and select Redundant Mode. Redundant Mode sends every packet over both connections, so it uses more cellular data. The free tier includes 5 GB per month with a free account.
