When you're on a train, your Wi-Fi and mobile data (4G / 5G) might be slow or unreliable. With Speedify, you can combine both connections on your iPhone or Android for a smoother experience. If you need even more speed—like for video calls or live streaming—there’s actually another way to get that. You can connect to multiple hotspots at the same time and use them together with Speedify.

Speedify's Pair & Share feature lets you easily share your 4G / 5G cellular data across multiple devices, including PC, Mac, iPhone, Android, and even Linux. No need for cables or complicated setup—it all works through the Speedify app. Check below to see how you can connect to multiple hotspots at once and use them together.

When you’re traveling by train during your work day, you need Internet connectivity that you can rely on. Here are a few reasons why you usually don’t get that from the train Wi-Fi:

• Poor cellular coverage - sometimes the train goes through areas of poor cellular connectivity where you are not able to use your 4G / 5G mobile data connection. This also impacts the train Wi-Fi you may be using.
• Crowded Wi-Fi hotspot - there are hundreds, if not thousands of people using the same Wi-Fi hotspot that the train operator provides. So each of those people eats up a certain amount of bandwidth, which is limited.
• Mobile data handover - when the train is traveling at high speeds, your 4G / 5G cellular connection will keep switching to new cellular stations that are closer to you, with the available bandwidth fading in and out as you move from one station range to another.

That’s why it’s important to use Speedify to combine multiple Internet connections - if one of them becomes sub-par, Speedify enables the others to compensate it and provide fast, reliable and secure connectivity.

The easiest way for this is to use Speedify’s Pair & Share functionality. This allows you to easily share and combine 4G / 5G cellular connections between devices to create a faster, more reliable connection for everyone.

Speedify's Pair & Share is like a supercharged personal hotspot. Instead of just one device sharing its internet, all paired devices can both share and receive connections at the same time.

Here’s what you need to do in order to use Speedify’s Pair & Share functionality,:

1. Get the Speedify app on all your devices and connect to the same Wi-Fi network. This can be created by one of your devices or you can use a public Wi-Fi network.
2. Make sure you have Pair & Share enabled on all devices. Start by pairing a device to share and receive.
3. You are now taking advantage of both your and others’ Internet connectivity for faster, more reliable and secure Internet while traveling by train.

Traffic between devices is fully encrypted, and you always maintain full control over which devices can do what - set permissions, limits, or unpair from other devices at any time.

Forget about Internet issues with the train Wi-Fi. As long as you have more than one phone to help, preferably from a different carrier, then you should be all good when using Speedify to join all available connections with the Pair & Share functionality.
