A SIM box aka SIM bank is a device used for GSM termination; in other words, it is used as a part of the installation for VoIP gateway installation. Depending on the model and capability, the device can hold a different number of SIM cards. Although the cards are stored or housed separately from the gateway, they are stilled linked to it.
A SIM box is not bound to a type or company of service provider as it can host SIM cards of different mobile service providers. This allows it to operate with multiple GSM gateways none of which are restricted to a specific location.
By holding the SIM cards separately from the GSM Gateways/VoIP, the operator can solve a number of problems such as SIM blocking and minimize their maintenance expenses. Most importantly, it allows the operator to manage any number of SIM cards belonging to different service providers which will enable work of different GSM gateways placed at different locations.
By connecting multiple SIM boxes to one system, the operator can not only keep an unlimited number of SIM cards from the GSM gateways but also use them to bypass VoIP installations. This allows keeping the SIM cards away from the GSM gateway. SIM box Gateway acts as a bypass key to enable blocked SIM cards to function even when a GSM gateway is at another location.
The way SIM box gateway works is quite simple but highly effective. For calls and SMS, it allows the operator of the SIM box to route international connections through the local VoIP connections which then lets the operator connect it as local traffic. This allows the operator of the box to bypass international rates; this means that the prices charged by the local mobile network operators can be undercut by the SIM box operators.
The SIM box gateway utilizes the internet to transfer the calls to a local area where the operator or the intended call is meant to be and the call is converted back to the local mobile network using a private exchange. The quality of service especially for international or non-domestic calls is quite superb as instead of using outdated technologies employed by the local mobile networks (like FR codecs or GSM HR), the modern technology of SIM boxes is armed with the latest cellular and telecommunication technology.
The process reduces the risk of blocking for SIM cards and enables a single card to be able to make calls from variable points. The way it does that is by allowing the operator to attach separate SIM cards for the GSM/VoIP gateways.
Different SIM box gateway systems employ different technologies which means that the amount of SIM cards they can cater to may vary. If the operator can arrange for high quality and a high-speed internet connection, they may place SIM cards separately from their GSM modules at a much greater distance. As the SIM cards that are utilized for different applications (for termination of SMS or for the termination of Voice traffic between the SIM box and GSM gateway) can be placed in the same SIM box irrespective of the destination, it becomes feasible for the operator to monitor and control them.
It is essential to have multiple locations (whether different regions of the same country or different countries in general) chosen for a variety of GSM gateways. This is vital as all the SIM cards that are being utilized for the termination of either voice or SMS traffic should not belong to single location and be placed in a single SIM box.
One way to further optimize the SIM box’s arrangement of the SIMS is by utilizing the algorithm for SIM rotation. This not only allows for better optimization of the resources each SIM card is taking but it additionally improvises to reduce the workload of each individual SIM card. This, in turn, reduces the suspicion of the original service providers. the way it works is by the division of the SIM cards in several groups that can be connected to different VoIP gateways of separate GSM modules. This allows for the system to switch or jump the functionality of one SIM card to another automatically, thus reducing the load of each SIM card over time.
To further block the SIM cards from being blocked, a technique called Migration of the SIM cards can be employed which creates the illusion of the movement of the user by transferring the specific frequency of the user form one GSM gateway to another. The technique is not limited to a specific location and the signal can be jumped from one city to another.
The usage of the SIM box gateway is becoming increasingly popular and facilitating the users on an international level. It is just a matter of its smart usage and a proper setup that can enable an operator to help corporations and businesses in affective and cheap marketing with increased outreach.

A good service provider will offer a variety of API options that include unsynchronized and synchronized options as well as have a good understanding on how to incorporate SMS into business applications and systems.
- Network Coverage
One should also consider how the messages will be delivered. Is the service reliable enough? Is it global or local? What is the quality provided? Many providers limit the number of messages and this is one way to determine the reliability and quality of service being provided.
Some upcoming providers can only connect to a limited number of networks while a truly established provider can connect with many networks on an international scale.
- Account Management and Support
Bulk SMS campaigns have to be properly managed with measured results. Hence, one should choose a bulk SMS gateway provider that offers easy-access full account management services. One can easily monitor the number of messages delivered or failed, and an overall traffic overview and a message log.
