If you have a business and frequently travel abroad, an eSIM combined with WhatsApp Business can be the ultimate solution for maintaining professional connectivity without paying exorbitant roaming bills. This guide is designed for freelancers, entrepreneurs, and executives who travel.

Why eSIM is perfect for the traveling entrepreneur
| Traveling entrepreneur's problem | eSIM Solution |
|---|---|
| Exorbitant roaming bill every month | Travel eSIM: local price, no surprises |
| Losing WhatsApp Business number when changing SIM | Dual SIM: keep your number always |
| No internet at destination to serve clients | eSIM active before landing |
| Local presence in destination countries | eSIM with calls for local number (optional) |
| Manage multiple lines/projects | Multiple eSIMs installed, activate the one you need |
WhatsApp Business setup with Dual SIM
The optimal setup for a traveling entrepreneur:
- Spanish SIM (physical): your business WhatsApp Business number — always active
- PuraSIM eSIM: cheap data abroad
- In Settings → Mobile Data: select the eSIM as your data line
- WhatsApp Business uses eSIM data, but your number remains the Spanish one
The result: your clients call and message you on the same number as always, while you pay local prices for the internet you use.
Real savings in communications
| Scenario | Annual cost without eSIM | Annual cost with eSIM | Annual savings |

| 10 trips/year of 5 days, Europe | €420 | €90 | €330 |
| 10 trips/year of 5 days, LatAm | €1,200 | €150 | €1,050 |
