What you see
The dashboard shows the phone offline, or the service stops overnight or after a restart.
Why it happens
Battery optimisation, manufacturer task killers, Data saver and force stop can interrupt the service. After a restart, SMSKit starts only after the first unlock.
What SMSKit needs and why
Background execution, internet access and startup handling keep the gateway reachable.
Permissions referenceHow to fix it
- Search Settings for SMSKit battery settings and choose Unrestricted or exclude it from battery optimisation. The Play build opens the optimisation list; the direct build can offer a one-tap request.
- Samsung: add SMSKit to Never sleeping apps. Xiaomi or Redmi: allow Autostart and set Battery saver to No restrictions.
- Tecno, Infinix, itel, Huawei, Oppo, Realme and Vivo: search Settings for auto-start and background activity and allow SMSKit. Labels vary by model.
- Allow background data for SMSKit and exempt it from Data saver. Keep Wi-Fi or mobile data connected.
- Do not force stop SMSKit. If you did, open it again and tap Start service. Unlock the phone once after every restart.
