SIM card vs eSIM vs pocket WiFi: practical decision notes
This choice should start with the phone. If the phone supports eSIM, eSIM is simple. If several devices need data, pocket WiFi deserves comparison.
| Before paying | Why it matters |
|---|---|
| Phone support | A locked or unsupported phone can make any plan useless. |
| Arrival route | Airport, hotel and first train route affect how urgent setup is. |
| Data habit | Maps and messages use less data than video, hotspot or work calls. |
| Backup | Airport WiFi, hotel WiFi or another device can save the first day. |
