# Why Your Office Doesn’t Receive 2FA SMS Messages (And How to Fix It)

It is Tuesday morning. An employee boots up their laptop to start working. When logging into the company network, the familiar message appears: “Enter the code sent to your mobile phone.” The employee looks at their screen: no service. After waiting a moment, they sigh and walk to the window on the other side of the department. Only then does the text message come through.



This scene, the now familiar walk to the window for a bit of signal, is a daily reality in many office buildings.






    
        
                                                
        
                            From a minor inconvenience to a productivity drain FACT
                        

Almost all business software today requires two factor authentication (MFA or 2FA) via a mobile phone. A failing mobile connection is therefore no longer a luxury problem. It is a structural barrier that interrupts workflows and wastes an unnecessary amount of time and frustration on an annual basis.


        
    
    


Why the Mobile Signal Stays Outside



The cause of this poor coverage lies in the building physics of modern and renovated buildings. To meet sustainability requirements and energy label regulations, buildings are heavily insulated and fitted with HR++ or triple glazing. This glass contains an invisible metal coating to regulate the indoor temperature.



This is great for the energy bill, but metal blocks radio waves. As a result, the office acts as a Faraday cage. Because the government only requires telecom providers to guarantee outdoor coverage, the 4G and 5G signals often simply stop at the front door.



The Dilemma: The Risks of Illegal Cell Phone Signal Boosters



IT and facility managers are well aware of this problem. The helpdesk regularly receives complaints about the lack of connectivity on the work floor. In the past, out of desperation, companies sometimes resorted to ordering cell phone signal boosters online, also known as repeaters.



However, installing this equipment is strictly prohibited. Uncertified boosters disrupt the public cell towers of telecom providers, which can lead to network problems for the entire neighborhood. Companies were therefore stuck. There was no workable indoor coverage, but actively boosting the signal was not allowed.




    
        
            The illegal route (Uncertified repeaters)
        
        
                        
                Purchase                Cheap cell phone boosters ordered online without a European certification mark.            
                        
                Technology                Blindly boosts all signals. This causes interference on the public telecom network.            
                        
                Risk                Strictly prohibited. Regulatory bodies actively track down this equipment.            
                        
                Consequence                Immediate disconnection, confiscation of equipment, and corporate fines running into the thousands of euros.            
                    
    
    



    
        
            The legal route (Smoothtalker via Voclarion)
        
        
                        
                Purchase                High quality, professional systems that comply with all European and local telecom legislation.            
                        
                Technology                Intelligent network control. Picks up the signal and distributes it locally without sending any interference back to the cell tower.            
                        
                Risk                Fully compliant and risk free.            
                        
                Consequence                Stable, reliable, and legal 4G and 5G coverage throughout the building for all providers. No fines, just productivity.            
                    
    
    


















A Legal Solution with Smoothtalker



Fortunately, there is now a workable and permitted solution on the market. Voclarion has entered into an official partnership with the Smoothtalker brand.



Smoothtalker equipment has all the necessary certifications for legal use. The system solves the indoor coverage problem and ensures that your organization remains completely within the law at the same time.





How the Smoothtalker solution works


    
                
            
                
                01
                
            
            
                Capturing the signal                An external antenna on the roof or facade captures the existing strong mobile signal from outside.            
        
                
            
                
                02
                
            
            
                Smart amplification                The signal is routed via a cable to the intelligent Smoothtalker amplifier inside the building. This optimizes the signal without causing any noise.            
        
                
            
                
                03
                
            
            
                Indoor distribution                The powerful signal is distributed evenly across the office floor via discreet indoor antennas.            
        
            
    


Compatible with All Providers



A highly practical advantage of Smoothtalker systems is that they work independently of specific telecom providers. The system amplifies all incoming mobile signals simultaneously and regardless of frequency.



It therefore does not matter whether employees have corporate devices from one provider or use their private phone with a different subscription to receive their 2FA code. Once the system is active, everyone in the building will have sufficient coverage again.



Reliable Coverage Everywhere



A normal workday demands reliable communication and logins that work instantly. Put an end to the frustrating walk to the window and ensure a seamless workflow for all your employees.
