Topcom Connect Prepaid

Worldwide Prepaid Data, Voice, and SMS connectivity

M2MData supplies Topcom Connect Prepaid SIM cards for global IoT, M2M, data, voice, and SMS connectivity without monthly subscription fees. With access to more than 500 mobile networks via MNO and MVNO partners in over 160 countries, these prepaid SIM cards offer reliable multi-network coverage for internationally operating devices and users.


Topcom Connect uses non-steered roaming. This means the SIM card is not directed to a single preferred network, but can connect to the strongest available network at the location. This improves coverage and continuity for GPS trackers, alarm systems, remote monitoring, mobile devices, travel applications, and long-life IoT devices. Non-steered roaming means that a device can choose a network based on available network strength, rather than following a fixed preferred order of operators.


The SIM card remains active until the prepaid credit is used up and can therefore last for more than 10 years. You pay for actual usage, without fixed monthly costs.

  • Data: from €1.75 per GB in the EU, no monthly fees
  • SMS MO/MT: from €0.20 per message
  • Voice MO: from €0.30 per minute
  • MT speech: free of charge
  • Optional phone number: European or British number possible
