O2 launch WiFi and 4G calling

O2 have launched a WiFi and 4G calling service, giving customers a new way to connect when making voice calls.

The move should make for clearer reception and better coverage, especially when making calls indoors.

What are 4G and WiFi calling?

Customers can now make and receive calls over the internet as well as using their standard mobile network.

O2 say calls will automatically and seamlessly switch between the network, WiFi and 4G to deliver an uninterrupted experience and reduce the chance of calls dropping mid-conversation.

The ability to make calls over the internet is nothing new – available on many apps including O2’s own Tu Go, but the new service’s seamless transition between WiFi, 4G and the mobile network makes these apps somewhat redundant.

Which phone and plan do I need for 4G and WiFi calling?

Currently, this service is only available to customers with an iPhone 7 or iPhone 7 Plus but O2 promises that support for more devices is coming very soon.

Pay-as-you-go customers are unfortunately out of luck: only SIM-only, Pay Monthly and business tariffs have access to 4G and WiFi calling.

Where can I get 4G calling?

While WiFi calling is immediately available to all eligible customers, 4G calling is only available in London, Leeds and Slough.

Coverage will gradually increase in the coming months, but there is no word yet on which areas will be prioritised.

“We’re rolling out this service slowly, so we get it right the first time,” says O2 in their announcement video.

4G calling also uses up the minutes on a tariff instead of the data.

This is certainly welcome news as many customers easily eat through their monthly data allowance while only using around 30 percent of their available minutes.

Who else offers WiFi and 4G calling?

Both EE and Three currently offer 4G calling services, both with significantly more coverage and handset compatibility than what O2 is offering.

O2 may wish to “get it right the first time”, but they’ll need to start extensive rollouts soon to keep up with the competition.
