The question of portability with eSIM causes a lot of confusion: Can I keep my phone number if I switch to an eSIM? Can I change operators while keeping my number and using eSIM? The answer is yes in both cases, but with important nuances.
What is portability with eSIM
Number portability (NP) allows you to change operators while keeping your phone number. eSIM adds a layer of flexibility: you can port to an operator that uses eSIM and receive your new digital SIM, without waiting for a physical card to be shipped.
| Portability type | Possible with eSIM? | Time |
|---|---|---|
| Change from Movistar to Orange (keeping number) | ✅ Yes | 1–3 business days |
| Change from physical SIM to eSIM with the same operator | ✅ Yes | 1–24 hours |
| Portability to a virtual operator (Simyo, etc.) | ✅ If they offer eSIM | 1–3 days |
| International portability (Spanish number → foreign country) | ❌ Not possible | — |
| Keep number during travel with travel eSIM | ✅ Yes (Dual SIM) | No wait |
Do you keep your number with a travel eSIM?
Here's the most important concept that many confuse:
- Travel eSIM (PuraSIM): this is a data-only eSIM. It does NOT replace your Spanish number. You can have it active simultaneously with your Spanish SIM thanks to Dual SIM. Your number remains the same.
- Spanish operator eSIM (Movistar eSIM, Orange eSIM): this replaces your operator's physical SIM. If you have already ported to the operator, your number remains the same — only the physical SIM format changes.
How portability to an eSIM operator works
- Contact the new operator (Movistar, Orange, Vodafone, etc.) and request number portability
- The operator initiates the portability process (1–3 business days)
- When portability is complete, you receive an eSIM QR via email or app
- Scan the QR on your mobile and install the new operator's eSIM
- The physical SIM of the previous operator is automatically deactivated
Spanish operators with eSIM
| Operator | eSIM available | Portability to eSIM |
|---|---|---|
| Movistar | ✅ | ✅ |
| Orange | ✅ | ✅ |
| Vodafone | ✅ | ✅ |
| Yoigo | ✅ | ✅ |
| Simyo | ✅ | ✅ |
| Más Móvil | ✅ | ✅ |
| Digi | ✅ | ✅ |
| Pepephone | ⚠️ Limited | ⚠️ |
Conclusion
Portability and eSIM are compatible. For travel, you don't need to port anywhere — simply add a travel eSIM as a second line with Dual SIM and you keep your number. To switch operators with eSIM, the process is identical to a normal portability, but you receive the SIM digitally instead of physically.
Frequently asked questions
Can I port my number when using eSIM abroad?
Number portability is a process that occurs on the Spanish network. You can initiate portability online from abroad, but your number will remain Spanish regardless of which eSIM you use for data.
If I port to an eSIM operator, do I lose my number?
No. Portability is legally guaranteed to keep your number. The process moves the number from one operator to another.
Can I cancel portability if I change my mind?
You have 1 business day to cancel an initiated portability. After that period, the process continues.
Does the PuraSIM eSIM give me a phone number?
No. PuraSIM data plans are data-only. For calls and SMS on your Spanish number, you need to keep your Spanish operator's SIM.
Can a travel eSIM number be ported to Spain?
No. Temporary numbers from travel eSIMs are not portable. They are temporary numbers from the plan's country of origin, not permanent.
