So here is my situation...what do you guys thing, is it worth to switch? Currently we have four iPhones on a FamilyTalk plan. 700 shares minutes, unlimited text and unlimited mobile to mobile. Line 1 (mine): Unlimited data grandfathered plan (Uses 1.0 - 3.5GB/month) Line 2: 3GB data plan (Uses 200MB - 600MB/month) Line 3: 3GB data plan (Uses 100MB - 400MB/month) Line 4: 2GB data plan (Uses 0.5GB - 2GB/month) Our total bill for the month comes out to $235+tax. Our total data usage right now is about 6.5GB on the high end (just looking back at 1 year of history and taking the highest month for each person). I'm thinking of switching to the 10GB/month Mobile Share plan. It would be practically the same price ($240 vs $235) but we would gain the use of FaceTime over Cellular as well as the ability to tether our iPads to the phones which is a big plus. It seems like we have a pretty good amount of headroom for additional data so the 10GB/month should be enough but is it worth giving up the Unlimited Data plan I have now, even though it seems I never use that much anyway?
