With SIM hosting, a SIM card is hosted in a modem that, just like a regular GSM connection, makes connection with the GSM network. Therefore, an ordinary GSM subscription is required, and all incoming and outgoing SMS messages are sent via that number.
We have a direct connection with the operators for our virtual numbers, who send all traffic directly to our numbers. This allows for faster and more reliable traffic. In addition to the virtual number's monthly costs, no additional subscription needs to be closed with an operator.
With a virtual number, there is no restriction on the number of messages you wish to send per day. With SIM hosting, most operators allow a maximum of 300 messages per day.
