It takes about a minute, and you can do it before you leave.
On iPhone
- Open Settings, then tap Mobile Service (or Cellular).
- Tap your FairSIM line. Your iPhone may have named it Secondary, Travel or Mobile Data; these are default names. If the line is off, turn on Turn On This Line.
- On the same screen, turn on Data Roaming. If you don't see it, open Mobile Data Options first.
- Go back and tap your usual line. Turn off Data Roaming.
- Go back to Mobile Service and tap Mobile Data. Choose your FairSIM line.
- On the same screen, turn off Allow Mobile Data Switching. This stops your phone from using your usual SIM for data.
