Have an IoT project but don’t know where to start?

Why choose VoLTE?

VoLTE stands for Voice over Long-Term Evolution, representing the next generation of mobile voice services. Unlike traditional voice calls that rely on 2G or 3G networks, VoLTE utilises 4G networks to deliver crystal-clear voice quality whilst maintaining your high-speed data connection. This means no more switching between networks when making calls – your voice and data services remain active simultaneously.

Enhanced call quality & performance

Our VoLTE SIM cards deliver:

  • Superior voice quality compared to traditional cellular calls
  • Faster call setup times with near-instant connections
  • Seamless handover between different networks
  • Improved battery life through efficient network usage
  • Better indoor coverage in many buildings
  • Support for both voice calls and video calls over 4G

We are the M2M experts.

Network compatibility

Our VoLTE service operates across multiple UK networks including Vodafone and O2, ensuring comprehensive coverage. When 4G isn’t available, calls automatically fallback to 3G or 2G networks, guaranteeing continuous communication. As networks evolve towards 5G, our VoLTE SIMs are future-ready to support upcoming communication technologies.

Business applications

VoLTE technology is ideal for:

  • Remote workforces requiring reliable voice communications
  • IoT deployments needing both voice and data capabilities
  • Rural areas where traditional network coverage is limited
  • Modern office buildings where 2G and 3G signals struggle to penetrate
  • Businesses transitioning away from legacy 2G and 3G networks
  • Organisations requiring high-quality voice for professional communications

Technical advantages

VoLTE provides significant technical benefits:

  • Single Radio Voice Call Continuity (SRVCC) for uninterrupted calls
  • Simultaneous voice and data usage without compromising quality
  • Enhanced network efficiency compared to traditional voice services
  • Improved coverage through better building penetration
  • Reduced battery consumption compared to VoIP alternatives like Skype or WhatsApp
  • Superior call quality through advanced audio codecs
