Burner

If you ever need a second line on your mobile phone, you need to try the Burner app and give it a go. It covers calling, texting, and picture messaging. It’s also a great way of avoiding offering your real number.
 
The calls through the Burner service are rerouted through their servers, which means that no one can actually see when you’re calling is coming from. It’s a service useful for dating, sales, deliveries, online shopping, and much more.
 
The service also integrates with Dropbox, Google Drive, and Slack, allowing users to archive messages and voicemails. There are no cumbersome contracts that need to be signed, and you can try the service for seven days before having to pay for it.
