Virtual SMS.

Many companies use SMS messages to communicate with customers. For example :

  • Marketing or Advertising
  • Second of two-level security on financial transactions
  • Notifications of events
  • IoT notifications
  • Voting in entertainment shows and maybe in UK elections.
These messages are not typed in through a phone keyboard but are generated and managed by a virtual SMS supplier.

There are many uses for SMS messages. They communicate with a user but as there is a cost associated with the SMS message as opposed to email there are fewer scam messages. SMS is inherently secure as opposed to email. SMS can work with low connectivity; email requires an Internet connection

There are a number of third part services that provide a send and receive SMS messaging service through an API. No actual SIM involved.

  1. To send an sms there will be a procedure within an API (such as with a number of POST parameters that will include the message, receiver_number and sender_account.
  2. To receive an SMS the sender will send their SMS to your virtual number, or a share of a virtual number. Some logic will route the SMS to a script on your server which will have the sender, data_time, rceiver, and message text as POST parameters.
