Almost no travel eSIM gives you a phone number: of 872 plans on sale in our catalogue on 21 September 2026, 12 include calls (1.4%) and 6 include SMS (0.7%). The other 860 are data-only. That single fact explains most of the confusion travellers have about verification codes, hotel callbacks and taxi drivers who want to ring you.
It is also the fact most buying guides skip. A data-only plan is not a defective phone plan; it is a different product. Here is the audit, what it means for the messages you actually need to receive, and the setup that solves it.
- Data-only: 860 of 872 plans (98.6%).
- Plans including calls: 12 (1.4%).
- Plans including SMS: 6 (0.7%).
- What you do not get: a local number to receive calls or bank codes on.
- What solves it: keeping your own line active alongside the travel eSIM.
What the audit found
| Finding | Plans | Share of 872 |
|---|---|---|
| Data-only, no calls or SMS | 860 | 98.6% |
| Calls included | 12 | 1.4% |
| SMS included | 6 | 0.7% |
| Both calls and SMS | 6 | 0.7% |
The pattern is consistent across suppliers and destinations: travel eSIMs are sold as data. Where calls appear at all, they are a bundled extra on a handful of plans rather than a feature of the category.
What actually breaks without a number, and what does not
Most of what people imagine losing, they do not lose. Calls and messages that run over data keep working: WhatsApp, FaceTime, Telegram, Signal, Messenger, Teams and Zoom are all data services, and a data-only eSIM carries them exactly like home Wi-Fi does.
| What you want to do | Works on a data-only eSIM? | Notes |
|---|---|---|
| WhatsApp, FaceTime, Telegram calls | Yes | They run over data |
| iMessage between Apple devices | Yes | Over data; SMS fallback needs your own line |
| Receive a bank verification SMS | No, not on the travel line | Keep your home line switched on |
| Receive a call on your usual number | Only if your home line is active | Roaming charges are your carrierโs |
| Give a local number to a hotel or driver | No | That needs a local SIM |
| Call an emergency number | Handled by the phone, not the plan | Emergency calling does not depend on your data plan |
The row that catches people out is the bank SMS. One-time codes are still sent as text messages by most banks and airlines, and a data-only eSIM cannot receive them. This is not a flaw in the eSIM; it is a reason to keep your own line reachable.
The setup that fixes it in two minutes
- Keep your home line switched on so calls and SMS to your usual number still arrive. Most phones let you do this while a second line carries data.
- Turn data roaming off on the home line. That is what stops the expensive part; the line can still receive texts and calls.
- Set the travel eSIM as your data line, so everything that uses the internet runs on the plan you prepaid.
- Tell people to reach you on an app for the trip. It is free, and it works on both Wi-Fi and the travel plan.
- If a local number is genuinely required, buy a local SIM in the destination โ but keep the data eSIM, because local SIM data is often the more expensive part.
Our dual SIM guide walks through those settings on iPhone and Android, and eSIM versus physical SIM covers when a local SIM is still worth the shop visit.
What about the 12 plans that do include calls?
They exist, and for a small number of trips they make sense: long stays where you will deal with local businesses by phone, or destinations where services call rather than message. But they are a rounding error in the category, and they are not a substitute for your own number โ the minutes come with a local number you have not given anyone.
For almost everyone, the better structure is the one above: your number for identity, a data plan for the internet. It also travels better, because the data plan changes country by country while your number stays the same.

Method, and what this audit does not prove
We read the calls and SMS fields on every product published in our own catalogue on 21 September 2026, excluding items hidden from the catalogue, and counted the values. The population is 872 plans from 14 suppliers across single-country, regional and global coverage. Stock changes daily, so the counts drift.
What it does not prove: this describes the plans we sell, not the entire travel eSIM market, and it reports what each plan states rather than what a network does. Whether your home carrier delivers texts to you abroad, and what that costs, is your carrierโs business and worth checking before you travel.

Frequently asked questions
Do travel eSIMs come with a phone number?
Almost never. In our audit of 872 plans on 21 September 2026, only 12 included calls and 6 included SMS, so 98.6% were data-only. A data-only plan gives you internet access, not a number that can receive calls or texts.
Can I receive bank verification codes on a travel eSIM?
Not on the travel line itself, because data-only plans cannot receive SMS. Keep your home line switched on with data roaming turned off, and codes sent to your usual number still arrive while the travel eSIM carries data.
Can I make calls with a travel eSIM?
Yes, over apps. WhatsApp, FaceTime, Telegram, Signal and Zoom all run on data, so they work normally on a data-only plan. What you cannot do is dial a local number from a phone number the plan does not give you.
How many travel eSIMs include calls and texts?
In our catalogue, 12 of 872 plans include calls and 6 include SMS, as audited on 21 September 2026. Where they exist, calls come with a local number that nobody has yet, so they rarely replace your own line.
Does WhatsApp work on a data-only eSIM?
Yes. WhatsApp is a data service and stays tied to the number you registered with, not to the SIM carrying data. Your account keeps working while the travel eSIM provides the connection, including for voice and video calls.
Will my own number still work abroad if I use a travel eSIM?
Yes, if you leave that line enabled on a phone that supports two lines. Incoming calls and texts arrive as usual; turn data roaming off for that line so the internet runs on the travel plan instead.
Do I need a local SIM to give someone a local number?
Yes. A local number for hotels, drivers or deliveries comes from a local SIM bought in the destination, usually with your passport. Many travellers keep both: the local SIM for the number, the travel eSIM for cheaper data.
Can I still call emergency services?
Emergency calling is handled by the phone and the networks it can reach, not by your data plan. Keep your usual line enabled where possible, and check local emergency numbers for the country you are visiting before you travel.
Bottom line
Travel eSIMs are a data product: 860 of the 872 plans we audited include no calls or texts at all. That is fine for almost every trip, provided you set it up properly โ keep your own line active with data roaming off so verification codes keep arriving, let the travel eSIM carry the internet, and use apps for calls. Buy a local SIM only if someone specifically needs to dial a local number.
