Virtual numbers for SMS: why an eSIM will not help

Two different products

A virtual number

A phone number tied to a service rather than a SIM. Incoming texts and calls arrive in a web interface or an app. Separate companies sell them, often by the day or month, sometimes per message. We do not cover such services and do not include them in the catalogue.

A travel eSIM

An operator profile in the phone's chip giving mobile data in a specific country for a specific volume and period. From the user's point of view it has no number: technically one exists inside the network, but you are not told it, incoming traffic is not routed to it, and it appears nowhere in the plan's specification.

Hence the confusion: both are sold online, both concern mobile connectivity, both are described with SIM-related words. They solve different problems.

What the catalogue data say

This field exists separately in the catalogue precisely because the question keeps coming up. The answer is identical across all six despite the services being very different: from an Uzbek Telegram bot with 1 111 plans to a Swiss company with an app.

The coincidence is not accidental. Travel eSIMs run on roaming agreements and partner networks where data is included in the plan while the voice leg and SMS reception are not. That is how the market is built, not an economy measure by a particular vendor.

So what do you do about the confirmation code

1. Leave your main SIM in the phone. The eSIM becomes a second profile, your Russian number stays on the network and keeps receiving SMS. Most operators do not charge for incoming texts in roaming, but check with yours.
2. To register with a foreign service you need a number from that country — and that is a job for a virtual number or a local SIM, not for an eSIM.
3. A local SIM requires a passport and a shop visit in most countries. But the number is real and the code arrives.
4. Check whether you need a number at all. Some services accept confirmation by email or through an authenticator app.

A separate note on data: an eSIM solves exactly the part of the problem that needs traffic. If the code arrives in a messenger rather than by SMS, then an eSIM is precisely the right tool — it supplies the data for the messenger to receive it.

How to avoid buying the wrong thing

Signs that what you are looking at is a travel eSIM rather than a number:

• The plan is described in gigabytes and days, not in minutes and messages.
• The listing has a destination country and a package volume.
• Nothing at all is said about a number — as opposed to «a number is included».

If a seller does promise a number, that is a different product and its terms must be read separately: which country's number, who owns it, what happens on non-payment, and whether it is later reassigned to someone else. Our catalogue holds no such offers, and we will not invent their specifications.

In the eSIM table the «own number» and «tethering» fields are shown explicitly for each service. A blank field there means «the vendor did not declare it», not «yes».

What else a travel eSIM does and does not do

• Tethering is declared by four of six: eSIM.World, Unisim, eSIM365, Just eSIM. Undisclosed at eSIM Tayyor and Yesim.
• Speed after the package is used up drops on «unlimited» plans, and the figures differ: up to 32 kbit/s at Just eSIM, up to 512 kbit/s at eSIM.World, up to 1 Mbit/s at eSIM365. A thirtyfold difference, usually absent from the plan listing.
• The threshold for that drop is not named by Yesim on any plan — it depends on the partner network.
• Permanent roaming — the number of days after which the partner operator may disconnect a profile — is undisclosed at all six.
