Intercom stopped working after the 3G shutdown?
Many GSM intercoms dialled residents or gate phones over the 3G network. When the networks closed, those units went silent. We’ll explain your options, from replacing the communication module where possible to upgrading to a modern video intercom.

Common signs of a 3G intercom failure
1
Visitors press the button and nothing happens
The panel lights up, but the call never reaches a resident’s phone.
2
Gate or entry intercom that dials mobiles
Systems that call a list of phone numbers are the most likely to be affected.
3
The SIM or network indicator shows no service
The unit can no longer register on a mobile network.
4
Residents can’t open the gate remotely
Dial-to-open or SMS commands have stopped working.
From a quick fix to a proper upgrade
The right option depends on the age and model of the intercom, the building and what residents need. We’ll be upfront about the trade-offs.
Option 1
Replace the communication module
Where the intercom supports it, a newer network module can restore calling. It’s usually the lowest upfront cost, but it keeps an older system in service.
Option 2
Replace the GSM intercom
A current-generation unit that calls over 4G or the internet, often reusing the existing mounting and wiring.
Option 3
Upgrade to video intercom
For apartment buildings, a modern video intercom with app calling, remote management and access control integration.
If it’s a whole building, it may be time to upgrade properly
If the intercom serves a whole apartment building, the 3G failure is often a good moment to fix other long-standing issues too.
Common questions about 3G intercoms
Can our existing intercom be fixed?
Sometimes. If the manufacturer offers a newer communication module for your model, calling can often be restored. We check this during the site review.
Will a 4G replacement stop working in future too?
Mobile networks do change over time. We explain the expected life of each option so you can weigh a lower-cost fix against a longer-term upgrade.
Does an upgrade mean new wiring?
Not always. Many replacements reuse the existing mounting and cabling. We confirm what can be reused on site.
Is there an ongoing cost?
Mobile-based intercoms need a SIM service, and some app-based systems have a subscription. We set out any ongoing costs clearly in the proposal.
