Where can I buy a Commtel intercom from?

Commtel operates on a strict trade-only policy. You must be a reputable installer (minimum of an NICEIC registration required for electricians) of access control, security systems and or gates and barriers, with the requisite electrical, IT or telecommunication qualifications.

If you are a current customer, you can purchase online when logged into your account on our website. If you do not have an account on our website, please contact our sales team who will be able to get this set up for you.

Please note that Optimus products can only be purchased through one of our approved distribution partners. You can find a list of our distributors here.

If you are not an installer, please contact our sales team for further information and to find a local installer.

What size SIM card do I need?

Our 4G and IP intercoms use a MIRCO SIM.

What type of SIM do I need?

We always recommend using one of our own SIM cards, as they’re designed specifically to work with our intercoms. However, if you’d prefer to use your own SIM, please make sure it has the following:

Calls
Texts – required for SMS alerts and when using one of our apps
Data – only a small amount is needed if we’re programming your intercom remotely
Marketing messages switched off – these can sometimes interfere with the intercom
Voicemail turned off

If you’re choosing a PAYG SIM, pop it into a phone first to register it with the provider’s app, so you can easily top up when needed.

For the best performance with our 4G intercoms, we recommend using SIM cards from EE, Vodafone, or O2. These networks provide the most reliable coverage and call quality. While third-party MVNO SIMs may work, choosing a major provider gives you the most dependable experience.
