CONTROL FREQ - CONTRACT SIM CARDS 

Control Freq offers SIM cards on exclusive tariffs set up for GSM products. Our SIM cards are on the major networks but not provided directly by them, we (our customers) don't have to deal with the major network's customer service, which is a bonus in itself!

Instead, our customers have dedicated account managers and customer service teams to deal with any enquiries. Our SIM cards run on a Virtual Private Network (VPN) ensuring more efficient and reliable service connectivity.

 


IDEAL FOR GSM ALARM DIALLERS WHERE CONNECTIVITY MATTERS!

Mission Critical SIM: Ask yourself 'what if?' ... If you can't bear the thought of failure or downtime, this is the SIM to take that fear away.

It connects to the strongest network to start with and literally jumps to another network if it loses signal. This SIM is recommended for GSM alarm diallers or when you're unsure which network would be the most reliable. It takes the pain out of SIM cards generally while providing peace of mind for a very low annual cost.
