I'm questioning the "unwanted data charges" related to SMS/MMS text messages. I never read the details of the bug fixes on patch updates, but for some reason today, I did and I noticed the above in the list. Strangely enough, I updated my iPhone 5c and less than an hour later, Verizon started the automated text alerts for data usage warnings. I received 6 messages within 10 minutes in the following order: 75% used warning, 90% used warning, 100% used warning, back to 75%, back to 100% and then to 1GB in ADDITION to my allotted amount. So, of course, I called customer service and explained to the very nice representative that I use WiFi 99% of the time on both lines - we have a network at home, my fiancé' is retired and is home everyday and I work in a medical facility with WiFi. I asked the rep to review our data usage history for the duration of the last 12 months, showing that we have never used above 0.3GB combined! The crazy part.....the rep believed me and started working on trying to contact Tech Support for us to see if they could help. Tech had a 20+ minute wait, so the rep checked back with us about 15 minutes in to let me know she was still there and she says, "Wow, you're right! While we have been on the phone, you have now used an additional 500MB of data, which is IMPOSSIBLE while in an active cellular call. I love my Apple products, but come on!! Please do better than this!! I have now spent over 2 1/2 hours on the phone with Verizon (who is scratching their heads btw) trying to figure out a way to make this stop. Fair warning my friends, CHECK YOUR BILLS!!!
