Outrageous Overages!
Worried about going over your mobile data cap and getting hit with overage charges? Speedify can limit how much cellular data you use while keeping you online.
Speedify is an app that combines two or more internet connections at once – such as Wi-Fi and your phone’s 4G/5G cellular data – for faster, more reliable internet. It’s cost-aware too: set daily and monthly data limits and Speedify favors Wi-Fi so you stay under your carrier’s cap. It works on Android and iOS.
With Speedify, your internet stays on when one connection fails.
When one of your connections drops, Speedify automatically routes your traffic to your remaining connections — so calls don't cut out and downloads don't stall.
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.

Know your Notifications
Nowadays, most service providers offer free, automated tools to remind you about your monthly data allowance. But, before you get to thinking your home or mobile Internet provider is doing you a favor, you should know that most of the time these tools aren’t enabled by default. If you want an automatic SMS sent to your smart phone when your data plan reaches within 1 GB of its monthly limit, you’ve got to enable those notifications in your service plan’s account settings.
Why not Wi-Fi?
Of course, just knowing when you’re close to reaching your bandwidth cap isn’t really enough. You pay a lot for Internet service so you can stay productive at home and on-the-go. But, if you’re left twiddling your thumbs because you’re just a few megabytes shy of your monthly data limit, what’s the point? We suggest you take advantage of Wi-Fi whenever you can. In coffee shops, hotels, and at your office, remember to always switch over to the free wireless network, leaving your precious mobile data intact for the times you need it most.
Speedify is Smart
Constantly keeping tabs on your available networks is a pain. But, that’s where Speedify comes in. Speedify lets you combine multiple Internet connections for faster speeds, increased reliability, and much more. One of Speedify’s coolest features is its ability to prioritize your networks based on cost and other factors.
In Speedify, each Internet connection lets you choose:
- Primary– Use this Internet connection all the time
- Secondary– Only used when connections set to ‘Primary’ are congested or unavailable. This setting is perfect if you want to use your 4G card or other costly Internet connections only when they’re needed to help keep your connectivity smooth
- Backup– Only use this connection to keep you on the Internet if none of the ‘Always’ or ‘Secondary’ connections are available
- Never– Don’t use this Internet connection
Once Speedify has the skinny on the various Internet connections you use from day-to-day, you can rest assured that you’ll be making the best use of the free bandwidth around you, and avoid overage charges without so much as lifting a finger.
