FAQ

Common questions

Is it accurate?

SimQuota

Does it drain my battery?

No. SimQuota samples usage every 60 seconds using a lightweight timer — the same approach used by the iOS clock. There is no continuous background process when the app is closed; iOS background refresh handles periodic updates.

Does it work with any carrier?

Yes. SimQuota works with any carrier on any network (4G, 5G, LTE). It includes a built-in database of 111 carriers across 35+ countries for automatic detection and roaming zone identification.

What happens to my data?

On the free tier, all data stays on your device — nothing is sent to our servers. Pro users can optionally sync usage snapshots to our backend for the web dashboard and family monitoring. See our Privacy Policy for full details.

Can I cancel my subscription?

Yes, at any time. Manage your subscription in Settings → Apple ID → Subscriptions. You keep Pro access until the end of the paid period.

Does it support multiple SIMs?

Yes. Pro users can configure up to 4 SIMs with individual limits, billing cycles, and roaming configurations. SimQuota can suggest switching to a different SIM when you enter a roaming zone.
