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.
