Travel eSIM + Virtual Number: Data Abroad Without Losing Your SMS

Fully Signal Team Published 3 min read
Quick answer

A travel eSIM gives cheap mobile data abroad but usually no phone number. A virtual phone number adds a real number for SMS and calls that you read online, so you get local-priced data and still receive verification codes and calls. Fully Signal sells both — data eSIMs in 210+ countries and UK, Australian and Brazilian mobile numbers — and partners can bundle them under their own brand.

Most travel eSIMs are data-only: great for maps and WhatsApp, but no number for SMS or calls. Pairing a travel eSIM and virtual number fixes that gap — and gives resellers a second product to sell with every trip.

The gap a data-only eSIM leaves

A data-only eSIM gives internet access. It does not give:

  • A number that receives SMS verification codes for bookings, banks or ride-hailing apps
  • A local number for hotels, drivers, landlords or employers to call
  • A stable number that stays the same across trips

Many travellers keep their home SIM on for SMS and pay for roaming. A virtual number replaces that.

How the combination works

NeedHandled by
Mobile data abroadTravel eSIM (what is an eSIM?)
Messaging and calling appsTravel eSIM data
SMS codes and textsVirtual number — read in your online account (what is a virtual number?)
Phone calls to a real numberVirtual number — forwarded to a SIP app over the eSIM's data (SIP forwarding)

The eSIM's data connection carries everything: the SMS inbox in the browser and calls in a SIP app.

Three common scenarios

1. Long stay in the UK or Australia

A student or working holiday maker arrives with a UK eSIM or an Australia eSIM for data, and a virtual UK or Australian mobile number for job applications, landlords and banks — set up before the flight.

2. Expat keeping a home number

A Brit living abroad keeps a UK virtual number for their UK bank and family, and buys a data eSIM for each trip (UK number without living in the UK).

3. Business in Brazil

A company entering Brazil uses a Brazilian virtual mobile number on its website and a Latin America eSIM for staff visits (Latin America guide).

Why resellers should bundle both

  • Higher order value. A trip becomes an eSIM plus a number.
  • Recurring revenue. Numbers renew every month or year, long after the trip ends (eSIM customer retention).
  • One supplier, one balance. With Fully Signal, partners buy eSIMs and numbers from the same panel, API and prepaid balance (one supplier for eSIM and numbers).
  • White label. Both products carry your brand, not ours.

FAQ

Does a travel eSIM come with a phone number?

Most travel eSIMs are data-only and do not include a number for SMS or calls.

How do I receive SMS while using a data eSIM?

Use a virtual phone number: its SMS arrive in your online account, which you open over the eSIM's data.

Can I take calls on a virtual number abroad?

Yes. Calls are forwarded to a SIP app on your phone, which works over any data connection, including a travel eSIM.

Which virtual numbers are available?

Fully Signal offers UK, Australian and Brazilian mobile numbers, with more destinations added regularly.

Can a reseller sell both under one brand?

Yes. Fully Signal partners sell white-label eSIMs and phone numbers from one account and one prepaid balance.

How to Price Virtual Phone Numbers for Resale: Margins, Plans and Bundles

To price virtual phone numbers for resale, start from your full wholesale cost (the monthly number price, any one-off fee and the outgoing SMS you expect to pay for), add a margin that covers support and failed payments, and round to a clean retail price. Most resellers charge a monthly price with a discount for 12 months, pass outgoing SMS through with a small markup, and keep incoming SMS and calls free, since they cost nothing at wholesale.
