How to Use Wi-Fi and 4G/5G Cellular at the Same Time on iPhone with Speedify

Enjoy Full Speed and Reliability with Speedify – the Fastest VPN for iPhone

Using a VPN on your iPhone is always recommended – it keeps you safe from snooping ISPs and cyber hackers, especially in today’s context with the net neutrality repeal. But security isn’t everything – you also need your connection to be fast.

Have you ever connected to a WiFi hotspot in search for fast Internet, only to discover that it’s running very slowly and you can’t get anything done? LTE is an alternative, but what about your data plan?

Introducing Speedify – the one and only fastest VPN for iPhone that combines WiFi and LTE at the same time, giving you security, speed and reliability, all under your iPhone’s hood!

Quick answer

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.

Speedify bonds any two connections into one — automatic failover, more speed, no dropped calls.
