5G Alarm Diallers

These are the most sophisticated and up to date alarm diallers available. They use the mobile phone networks but don't require SIM cards with the connection to the networks pre-paid for 5 years at the point of manufacture (renewable).

They will dial and message an unlimited number of phones and have unique features such as conference mode where you can talk to other call recipients to discuss why the alarm is sounding and how to handle it. They can be wired to silence the alarm by pressing the # key on your phone or by saying the word 'silence' during the call.

These diallers have access to the latest IoT networks (LTE-M and NB-IoT on Vodafone and O2) which are part of the 5G 3GPP specification which is being rolled out across the UK. We already have 98% coverage in the UK with the rollout completion expected at the end of 2024. Where there is no IoT coverage the device reverts to 2G on EE, Vodafone or O2.

If my dialler stops working how would I know?

The 5G IoT networks, particularly NB-IoT, offer connectivity deep underground and inside buildings. They work where mobile phones do not work. The network sends the data to the dialler 2048 times so the dialler can determine the data from the background noise where there is barely any received signal. This is how the 5G dialler achieves such high levels of sensitivity. The downside? It's a slower. Messages can have up to a 1.6-10s delay. 1 bar on your phone outdoors will give almost full signal on NB-IoT.

Where the signal is better the dialler will use the high speed Vodafone or O2 LTE-M network. Finally, where no 5G networks are available, the dialler will fall back to 2G.

It's worth noting we discontinued our 2G, 3G and 4G diallers because they're the wrong technology for dialler applications. Use a 5G dialler. It's the correct choice. There are no VoLTE or IMS issues with the iot-portal diallers.


The Alarm Dialer is ideal for use in Burglar or Fire Alarms as a universal fit cell phone GSM Auto-Dialer/SMS Message Sender with email. With 4 inputs both the intruder alarm bell and set/unset status can be monitored.

Similarly, on fire panels the fire alarm bell and fault output can be monitored. By default, alarm activation on input A triggers SMS messages and telephone dialling (messages are read out during the call). Set/unset or fault activation on input B triggers emails sending which is free.

All setup is done online using a PC or smart phone. Each messages can be fully customised using the online portal. Basic programming can also be performed by SMS.

Every 4 minutes the unit is contacted by our server to ensure it is functioning correctly. Any critical faults found are sent to the master user by SMS and email.

Service charges on all 4 UK networks (and 100+ international) prepaid for 5 years (current service charge is £20/5yr). 

Can be programmed and controlled via SMS and email in addition to the PC/Smart Phone.

Can I use my own SIM? No this is not possible. We don't recommend using mobile phone SIM cards in alarm diallers. The networks provide the IoT bands for this purpose. The mobile phone bands and SIMs are for mobile phones.
