Does ZenSim offer 5G and hotspot sharing?+

Yes to both. 5G and hotspot sharing are confirmed, and instant activation is also listed under 5g, hotspot and instant activation. The featured plans therefore cover the three features most travellers look for on a travel eSIM.

Who runs ZenSim and where are they based?+

Can I top up ZenSim data while travelling?+
