Invigoӳ SIM OTA module allows to remotely control SIM parameters such as SMS-Center address, preferred network lists, and cell broadcast channels.

Roamers contribute significantly to operator revenues. It is therefore essential for both operator and roamer to control network selection. On one side, steering a roamer to a preferred network allows the roamer to save in roaming costs and on another side, it allows group of operators to consolidate roaming revenues within the group. Invigo's SIM OTA module, integrated with the SMS Welcome service, allows dynamically and remotely updating the roamer's preferred network list.
