From checkout to connected in four steps

An eSIM is a SIM built into your phone. Instead of buying a plastic card when you land, you download a plan before you leave; and keep your own SIM for calls and texts.

  1. 1

    Check your phone

    Your phone needs eSIM support and must be carrier-unlocked. Dial *#06#; if you see an EID, it has eSIM hardware.

    Install before you go

    Your eSIM arrives by email and in your account within a minute or two. On Wi-Fi, scan the QR code (or enter the codes manually). It takes about two minutes.

  4. 4

    Switch on when you land

    Turn on the Wayline line, enable data roaming for it and select it for mobile data. Your phone connects to a local partner network.

Installation and activation are not the same thing

This is the single most useful thing to understand about travel eSIMs.

Installation

Downloading the eSIM profile to your phone. Needs Wi-Fi. Do it at home a day or two before you travel. Usually possible only once per eSIM.

Activation

When your plan starts counting days. For most plans, it happens when the eSIM first connects to a partner network in a covered country; the plan page always says.

FAQ

Questions, answered

Short answers to what travelers ask most. Our Help Center goes deeper.

All questions
What is an eSIM?
An eSIM is a SIM built into your phone. Instead of inserting a plastic card, you download a mobile plan to it; usually by scanning a QR code. Most phones released since 2019 support eSIM and can hold several eSIM profiles at once.
How does a Wayline eSIM work?
You buy a plan for your destination, we email your eSIM, and you install it in your phone's settings. When you arrive, your phone connects to a local partner network through the Wayline line, while your regular SIM stays installed for calls and texts if you want it.
Is my device compatible?
Your phone needs eSIM support and must be carrier-unlocked. The quickest check: dial *#06#. If you see an EID number, your phone has eSIM hardware. You can also search your model in our compatibility checker. Support can vary by the country or carrier your phone was bought from.
How do I install an eSIM?
On Wi-Fi, open Settings → Mobile (or Cellular) → Add eSIM, then scan the QR code from your order email or account. If you can't scan, enter the SM-DP+ address and activation code manually. Our step-by-step guides cover iPhone, Samsung, Pixel and other Android phones.
Can I install it before I travel?
Yes; we recommend it. Install at home on Wi-Fi, then leave the Wayline line switched off. When you land, switch it on, turn on data roaming for that line and select it for mobile data. For most plans, validity only starts once the eSIM connects in a covered country.
When does my plan's validity begin?
It depends on the plan, and each plan page states it clearly. Most plans start when the eSIM first connects to a supported network in a covered destination; not when you buy or install it. Installation and activation are separate steps.
Can I keep my WhatsApp number?
Yes. WhatsApp is linked to your account and phone number, not to the line carrying your data. Keep your usual SIM installed, use Wayline for mobile data, and WhatsApp keeps working with your normal number.
Can I keep my existing SIM?
Yes. Phones with eSIM support two lines. Keep your home SIM active for calls and texts (your home carrier's roaming charges may apply if you use it), and set Wayline as the line for mobile data.
