Most potential dangers of SIM replacement are physical.
Key facts
- On Samsung devices: open the Their Files app, find the SD Card, tap the three-dot menu next to it and choose Unmount
- You'll get a similar result if you turn on airplane mode, wait 30 seconds before swapping the SIM and turn airplane mode off again once the new SIM is inserted
- If you have a dual-SIM phone that supports two physical cards, check which SIM you intend to swap before you begin
- If your phone has a SIM tray, it's not something you likely open often, but there are still reasons
Summary
A quick step removes the small chance of anything going wrong and requiring more of your time. If your phone has a SIM tray, it's not something you likely open often, but there are still reasons to. Most of today's smartphones let you switch SIMs with the phone on, so you don't need to switch your device off for the process. They're talking about physical SIM cards, which you have to remove from your phone by hand. eSIM replacement should be as simple as using a QR code, carrier app or direct transfer between different smartphones. Optionally, power down your phone or enable airplane mode.
