Virtual telephone numbers, which are also famous as DID (direct inward dialing) and access numbers, perform the same functions as traditional phone numbers. However, a virtual number is not connected to any telephone line or operator, which makes it more flexible for users. What is more, DID numbers can work without a SIM card and they are not associated with a single device. All you need to start using an acquired number is to be connected to the Internet.

Online telephone numbers are used for various purposes. In fact, key features, which an online number can offer, depend on a certain type of chosen number. Thus, for example, if you need to provide verification in the social network account but you do not want to demonstrate your real phone number, it is a great idea to use a service of disposable SMS numbers.

It is possible to familiarize yourself with different types of network telephone numbers on the official site of Telnum virtual number provider.

It is customary to distinguish numbers according to the duration of use (permanent, temporary, and one-off), covered area (toll free and local), and main action direction (numbers for calls, fax, and messages).

Key Characteristics of Online Telephone Numbers

There are some reasons why the acquisition of a network number is a good idea:

• Money save (cost of international calls and SMS via a virtual number is lower than local communication via a standard number)
• It is possible to use multiple numbers
• No connection to any device
• Simple connection and deactivation
• Security of the personal and financial information
• Protection of the real number during verification processes
• Possibility to monitor calling statistics and billing reports

Virtual numbers are considered to be a technology of the future because they allow users to avoid a lot of limits and restrictions and open new communication opportunities.
