Call and text on your home tariff from another country
WiFi calling routes ordinary calls and texts over a WiFi or data connection instead of the cell network. Abroad, that means you keep your own number and your home plan's rates — with no roaming surcharge just to connect.
What WiFi calling is
Also called Wi-Fi Calling or VoWiFi, it's a standard feature your carrier and phone support — calls and texts carried over the internet, using your normal dialer and number.
Over WiFi or data
When there's no good cell signal — or you're abroad — the call travels over WiFi (or your data connection) instead of a mobile mast.
Your real number
It's not an app. Calls and texts use your actual number and your normal phone dialer, so people reach you as usual.
Home-plan billing
Calls follow your home plan's rules — connecting over WiFi carries no roaming surcharge, though plan minutes and international rates still apply.
Why it means calling on your home tariff
This is the part travellers miss: with WiFi calling on, being in another country doesn't automatically mean roaming charges for calls and texts.
- A call over WiFi calling is billed as if you were at home — no per-minute roaming surcharge to connect.
- Calls to numbers back home are usually treated like a normal domestic call on your plan.
- Texts (SMS) to and from your number keep working — handy for bank and two-factor codes.
- Your plan's normal rules still apply: it can use up plan minutes, and calling international numbers can still cost extra.
How to check and turn on WiFi calling
It's a single toggle, but the path differs by phone. Pick your platform to see the steps.
- 1Open Settings and tap Phone.
- 2Tap "Wi-Fi Calling".
- 3Turn on "Wi-Fi Calling on This iPhone".
- 4Confirm your address for emergency calls if asked. A "Wi-Fi" label by your carrier name means it's on.
Don't see the option? It's set by your carrier — some don't offer it, or only on certain plans. If it's missing, ask your carrier whether WiFi calling is enabled for your line.
Pair it with a travel eSIM
The strongest combo abroad: a travel eSIM for cheap data, plus WiFi calling on your home SIM so calls and texts stay on your number without roaming — even when you're not on WiFi.
- 1Add a travel eSIM and set it as your default data line.
- 2Turn OFF data roaming on your home SIM so it never buys pricey roaming data.
- 3Keep WiFi calling ON for your home line so its calls and texts ride over the eSIM's data or any WiFi.
- 4On iPhone, "Allow Cellular Data Switching" lets the home line borrow the eSIM's data so calls ring through even off WiFi.
Check before you rely on it
WiFi calling is a carrier feature: some carriers restrict or charge for it abroad, and your plan's minutes and international-call rates still apply. Confirm with your carrier that WiFi calling works overseas on your plan before you travel — and always keep a way to reach local emergency services, which WiFi calling may not route correctly.
WiFi calling questions
There's no separate charge to connect over WiFi — calls follow your normal plan's rules. But plan minutes can still be used, and calling international numbers may cost extra.
Generally no — a WiFi call is billed as if you were home. Some carriers do restrict or charge for WiFi calling abroad, so confirm with yours first.
Any WiFi works. On a dual-SIM phone your home line can also place WiFi calls over a travel eSIM's data, so you're covered even without WiFi.
No. WiFi calling uses your real number and normal dialer, so anyone can reach you; app calls only work between people using the same app.
It's controlled by your carrier. Some don't offer it or limit it to certain plans. Ask your carrier to enable WiFi calling on your line.
