I Have just bought an iPhone 6s Plus but my wifi for using on the internet, however seems that sometimes the connection is dropped and iphone automatically then connects with 3g, therefore I then get charged - has cost me loads this week
how do I switch the data servicing settings so It can only connect through wifi when available? Also I want just to make sure this wont have any effect on texting & normal calls. Thanks in advance for confirmation of this & any additional info
