Whether you're at home, in a coffee shop or at the office, if you're having a signal problem, you can use WiFi to call as normal. And 4G Calling lets you make calls over 4G, meaning clearer calls.

Wifi and 4G Calling use your minutes and not your data. Your calls are included as part of your usual voice tariff allowance, and out-of-tariff calls are charged at your standard rate.

You'll move seamlessly and uninterrupted between WiFi and 4G network coverage to continue your call, while being able to check your mail or browse the Internet at the same time.

If you have a compatible handset¹, a connection to a WiFi service or 4G network, and your data profile is correctly configured to the plan.com data service², WiFi/4G calling is available to you.
