The SimFuse app and your phone may show different usage because their counters cover different lines, periods or reporting times.
Compare like for like
- Confirm that the phone counter is for the SimFuse line.
- Compare the same dates. iPhone counters may need a manual reset; Android devices can use a configured billing cycle.
- Include hotspot traffic and background downloads.
- Refresh SimFuse with an internet connection and allow for delayed network reporting.
The plan balance is based on network records, but the latest usage may not have reached the app yet. Neither an old reading nor a missing reading proves that data remains.
If the gap is large or persists, contact support with both readings, their dates and the eSIM concerned. Do not run repeated large downloads just to test the counter.
