FAQ
What people usually ask before getting started
What is OneSIM?
OneSIM is a premium SIM / eSIM service built for global connectivity with privacy and control as core product values.
Is it only for travel?
No. OneSIM is designed for cross-border use, but it can also be used in everyday domestic use.
How do I activate my OneSIM?
Three simple steps. First, choose your service option and complete checkout — your included number(s) are selected at that stage. Second, install on your device: for eSIM, scan the QR code sent to your email via Settings → Mobile/Cellular → Add eSIM; for a physical SIM, insert it when it arrives. Third, connect — security-first defaults are active automatically from that point on. No further setup required.
How do I manage my service after purchase?
Users use the OneConnect Client Cabinet to manage options, features, numbers, and account settings.
What identity and calling controls are included?
Set your visibility, control which number is displayed when you call, and switch your network ID whenever needed.
What does "unlimited" data actually mean?
Unlimited means you don't buy data packs or track every gigabyte. OneSIM is built for everyday, high-reliability mobile use — travel, work, messaging, navigation, email, browsing, and moderate hotspot use. The service is subject to a fair usage policy to protect network quality for all users. Not covered: continuous HD/4K streaming, 24/7 background downloading, torrenting, P2P sharing, running servers, or reselling the service. OneSIM is premium unlimited for normal use — not a replacement for home broadband or a streaming box.
