Answers
Answer:
1. There maybe number of reasons for the delay in delivering of Nick's message. The most common one is the lack of proper network connection. It usually happens to us as well. The signals lag behind and so the message is not capable to be delivered.
2. Although network connection is most common problem in undelivered message, there are yet other reasons that can come into light if network problem isn't the problem.
- Invalid Number - The message won't be delivered if it is not valid. By valid, it means it should exist. A valid number always have 10 digits.
- Router - Although most of the messages are directly sent to the recipients, some are sent through a different router, which can unsend the message if it violates any of router's criteria.
- International communication - If you are sending message outside your country, that requires special networks and they cost more as well. Not having these, the message won't be delivered.
3. Telecommunication companies play a vital role in the whole thing of message delivery. They are the one who possess technology which is basically required for communication through internet, phone, cables, etc. They have the infrastructure required for sending voice, video, text, etc messages anywhere in this world by means of their technology.
4. Apart from mobile phones, radio waves are used in number of operations. They are basically used in broadcasting of FM radios. They are also used in military communications. Wireless computer networks can also be included. They are used in number of other fields as well.
