What to Do With Your Own Number Abroad: Running a Home Line and a Travel eSIM
The question that stalls people right after buying a travel eSIM: what do I do with my own number? Switch it off and you miss bank codes. Leave it on and you fear roaming charges. The answer is simpler than it looks — keep your number, turn off only its data, and let the eSIM carry the internet. Here is why, and exactly how to set it.
Should I switch off my home number abroad? Three approaches
| Approach | Texts still arrive? | Roaming charges? | Who it suits |
|---|---|---|---|
| Keep the line, turn off its data roaming (recommended) | Yes | No data roaming charges | Almost everyone |
| Whole phone in airplane mode | No | No | Nobody who needs a verification code |
| Physically remove the home SIM | No | No | Only if the tray is needed for a travel SIM |
| Change nothing | Yes | Very likely | Nobody |
Pulling the SIM out was the physical-travel-SIM era's answer. The whole point of an eSIM is that you do not have to: one line handles texts, the other handles data, and both are true at once.

The two switches people confuse
- 🔑 Home line data roaming → OFF. This is what keeps roaming charges away.
- 🔑 eSIM line data roaming → ON. A travel eSIM reaches the local network by roaming, so switching this off leaves you with no connection at all. The two go in opposite directions — this is the most common misconfiguration we see.
Home number and eSIM together: FAQ
Should I turn my phone off abroad?
No. Keep your home line active and switch off only its data roaming. You still receive SMS verification codes, and no data roaming charges accrue.
Could I still be charged for voice roaming?
Only if you make or answer an international call. If you are worried about answering by accident, most carriers let you disable voice roaming in their app or by contacting support.
Why does the eSIM need data roaming ON?
A travel eSIM connects by roaming onto a local partner network, so data roaming must be enabled on that line. Confusing this with your home line's setting is the most common reason a correctly installed eSIM shows no data.
How many eSIMs can a dual-SIM phone hold?
It varies. Newer iPhones store several eSIMs but limit how many are active at once; Android differs by manufacturer. Check the compatible device list if unsure.
Should I delete the eSIM when I get home?
You can delete it, or leave it in place and buy a fresh plan next time you visit. Either way, switch mobile data back to your home line and confirm its data roaming is still off.
Still no data after all that?
