Modern offices lose a huge amount of money due to colossal spending on conversations both within the company and with clients. Without this, it is currently impossible to develop a business, provide services, and attract customers. Mobile operators provide a certain amount of minutes for other operators, including landline numbers, but this is hardly enough for those whose work is in continuous negotiations. During the day, a person is forced to call from a work phone to mobiles, which leads to significant expenses. GSM gateways are designed to bundle existing communication formats into one device, the cost of which is relatively low.

A SIM bank is equipment that allows you to connect several SIM cards to the system at the same time. What is their principle of operation? After connecting SIM cards via a GSM gateway, control will be carried out through a preset IP network. The gateways themselves can be located anywhere in the world, and SIM cards will remain at hand. The operator will fix the location of the gateway, not the SIM. Designed for remote control.
Such a device for the majority of ordinary people remains incomprehensible, and therefore unnecessary. GSM gateways are used to convert analog signals into IP telephony or digital signals. In fact, it is a bridge that allows traffic to be transmitted in any direction.
The device makes it possible to connect several SIM cards to one unit. However, the functionality of the bridge is somewhat broader:
Sims can be replaced at any time or swapped. The operating scenario of gateways, which can be designed for 1000 SIM cards, are also programmed separately. Gateways can be docked with each other, which makes it possible to change SIM in different cities and even countries. Thus, the illusion is created that the card is moving.
The advantages of such equipment are obvious for large firms and large enterprises. For greater convenience, the main advantages are shown below in the form of a comparative table:
What to look for | Description | Benefit |
---|---|---|
Keep in touch | Installation of a cell parallel to a stationary bridge. | If the person does not answer on the landline phone, the call will be automatically transferred to the mobile. Employees always stay in touch. |
Long distance and international calls | It will be necessary to install VOIP-GSM gateways in another country or region. The connection is carried out through an active VPN channel through office PBX. | The cost of such services will be equal to on-net calls. |
Remote office equipment | The area must be covered by one of the existing bridges. There may be several reasons for this decision: • the signal level of the operator is not strong enough; • seasonality of the object's use; • irrationality of laying full-fledged wire telephony. The effectiveness of using an external antenna will be questionable. An ordinary telephone line interface is connected. | Irrational laying of telephone cables to remote objects. After installing the device, a mini automatic telephone exchange, a radiotelephone or a conventional device is connected. |
Save on phone bills | The signal is being converted from mobile to telephone. The cost will be equal to making a mobile call. Savings are made due to self-installation of SIM cards in cellular bridges, which are characterized by the presence of corporate tariffs. Traffic becomes unlimited, but for a fee. Thus, any calls will go into on-net mode. | A significant reduction in the cost of servicing mobile operators for individuals and companies. Saving on telephony up to 75%. |
