DID stays for Direct Inward Dialing number. They are visual numbers that allow you to route calls to your existing phone lines. That is the geeky explanation of the word. For the rest of humanity, a DID is a phone number that you can use for making and receiving through the BNESIM App. You can activate multiple DIDs from 40+ countries in seconds and receive unlimited calls for free! You can also activate the call forwarding to one of your DIDs to never miss a call. How cool is that!? To get a DID, visit the DID SETTINGS area of the Self Care and tap GET MORE PHONE NUMBERS. The first DID is free for the first month!
