At Commtel, we’re dedicated to making the install experience as seamless and straightforward as possible. In 2012, we launched our intercom SIM card solutions, offering our customers a range of tailored tariffs alongside their Telguard or Optimus door entry systems.
Our enhanced M2M SIM cards are specially designed to be used in machines, with a range of tariffs and a quick and easy activation process.

Which Security System SIM Card Should I Use?
With so many network providers out there offering a wealth of tariffs to choose from, it’s tough to know which is the right Intercom SIM card for your system. Most SIM cards are designed for use within mobile phones and not static machines, so choosing the right one is crucial.
It’s hard to know what to look for when selecting your M2M SIM card, so here are our top tips on what to look out for!
