Call+ is changing! We have merged Call+ and Message+ to combine all calling and messaging experience in only one app.
You can download the new Call+ app in https://itunes.apple.com/gb/app/vodafone-call+/id833409201?mt=8 where we introduced a freshly design update and exciting features.
As for this Call+ app, you can confidently delete it as long as you have the new Call+ app installed - you will not lose anything.
Enjoy the new experience!
