I’ve been using Caller id Changer Sec for a couple months now. It’s basically an app that lets you make calls and call back missed calls without your real number showing up. Pretty solid if you’re into that kind of thing.
Here’s what you do: you can use the app to place calls through the internet instead of your cell provider. There’s also a feature that checks if the number you’re calling is a premium rate number, and it’ll alert you and cancel the call if it is. And you get some free credits to use the app, which is nice.
Look, if you’re the kind of person who cares about privacy and avoiding charges on your cell bill, you’ll probably like this app. It’s not perfect – the setup can be a bit confusing at first – but overall it does the job. Worth checking out if that’s what you need.
