My iPhone 5 is using up data like crazy and it is unable to connect to any wifi networks. There will be people near me that can connect perfectly fine, but my phone will not connect. I talked to someone with technical support and they told me to update my phone to the new software update and I am unable to do that because to update your phone you need to be connected to wifi. I am wondering if anyone else is having similar problems or if anyone has any advice. Thank you.
