How SAIMING works
Get SAIMING, install one persistent eSIM and choose the connection that fits each journey.
From phone to destination
Before you install

Confirm the exact phone, tablet or laptop supports eSIM and is not locked to another carrier.
Use the guided setup on Wi-Fi. Add the eSIM once and keep it on your device for future journeys.
Leave your existing SIM as the default line for calls and messages unless the verified SAIMING guide tells you otherwise.
When the service is ready, select SAIMING as the mobile data line for this journey.
Turn on data roaming for the SAIMING line only when the destination guide instructs you to do so.
Open a page or map, then check the App for the current connection and usage state before relying on service.
Device paths
Names can vary by phone model and software version. Use these paths as orientation, then follow the on-screen SAIMING guide.
Open Settings, choose Mobile Service or Cellular, then choose Add eSIM and follow the guided installation.
Open Settings, choose Network and internet or Connections, then open SIMs or SIM manager and add an eSIM.
Only cellular models with explicit eSIM support apply. A Wi-Fi-only tablet cannot install a mobile plan.
Confirm the laptop has both a cellular modem and eSIM support, then use the manufacturer mobile-network settings.
Stop before deleting an installed eSIM. Open troubleshooting or contact Customer Support with your phone model and the step you reached — never send an activation code.
