The main problem You face when opening a bulk SMS business, is SIM blockage. Cellular providers keep blocking SIM cards for what they consider "excessive use" which forces You to buy more and more SIMs, which turns to a major drain on Your revenue. To help you combat that, there are several features installed into the Gateway.
The SMS Server has a page which enables You to apply counters to each SIM installed in the Gateway. Daily quotas will prevent You from exceeding the daily amount for Your cellular plan. The counters can be configured to disable sending from a particular SIM card after a given number of messages, which will enable You to distribute the load between several SIM cards - each module can hold up to 4 or even 10 SIM cards, depending on the cellular card's model. You can configure each module to swap to another one of its SIMs after a given amount of messages sent, so You don't have to send all its relative portion of the job at once, reducing the risk of blockage. You can, for example, configure the counters to swap to another SIM in the module every 150 messages and completely remove it from the SIMs' roster for that same module after 900. That way, the module will send 150 messages from a SIM card and swap to another, until it has gone through all of them (there's the option to configure it to switch between SIMs at a random order) and repeat that 6 times over, until they are all disabled from sending (6X150=900).
CHANGE IMEI (EMS+):
The SMS Gateway has an optional module that will enable You to assign a different IMEI to each SIM, so the module will assume a different identity when swapping to that SIM. That way it will not show a single cell phone using 10 different SIMs, but rather 10 cell phones, working at different times, which is normal activity.
VOICE CALL GENERATOR (VCG+):
The Gateway also has an optional feature that allows You to send messages between the different modules, thus showing it's not only sending them, but also receiving them, further giving the appearance of regular human behaviour.
To complement the VCG feature, the Gateway also has a feature that will make messages to the same number go out the same module, making it seem that there is regular traffic between two cellular phones, just like in every day communications, by and large, You exchange messages with the same people.
