No surprises

  • When it starts: the 15 days count from the first attach to a covered network.
  • Speed: no slowdown from us before the 2 GB are used; the local network sets the top speed.
  • Hotspot: Yes, it uses the same GB. We never block it; rarely, a local network limits it. It counts toward the 2 GB.
  • When the 2 GB are used: nothing more is charged and nothing renews by itself. Add GB to the same eSIM from your ticket page.
  • Data only: your own number stays on your main SIM for calls and SMS.
  • Unused and not installed: cancel within 30 days of issue for a refund to your card, less the card fee (within 14 days in the EU and UK, your whole payment). After the profile is on the phone, remaining data is not cash. Refund policy
  • Not connecting? A person answers at hello@inboxesim.com in minutes, 24/7 and works it out with the network. No chatbot.
