What About Your Home Number?
Most travelers keep their home number working too:
- Use travel eSIM for data
- Use home eSIM for incoming calls/texts
- Set roaming off for home line to avoid charges
- WhatsApp from home number remains accessible
This is the “best of both worlds” approach.
Setup Before You Leave
Best practice:
- Buy eSIM 1–2 weeks before trip
- Install profile while still home (need internet)
- Don’t activate yet (some plans start immediately, others on first connection)
- Read provider’s activation guide
- Test on arrival at destination

| Cuba | Limited options |
| Some African countries | Limited coverage |
| Most major destinations | Excellent options |
Always verify your specific countries before purchasing.
