Does anyone have any recomendations as to what is the best way to measure Data daily usage on an iPhone
Thanks for posting about you data usage. So I can give you the best recommendation I would like to ask a few more questions.
Are you just trying to view what app uses what amounts of data or are you looking to restrict apps using mobile data?
What software version are you currently running on the Iphone?
It may be worth having a read of the Geek Squad's guide on how to monitor your data usage.
If you would like more assistant just let me know.
