I have AT&T Family plan. 5 accounts. $15/month per user for unlimited talk, txt, +125/month for 10 gb data shared ($200 total a month). As i posted earlier, AT&T stopped subsidizing phone prices for upgrades, making upgrades useless. Meaning, that instead of you just paying a flat fee for new upgrade (they give you the phone for cheaper price) and paying same amount/month, now they charge you full price over 12/24/30 months, so your monthly bill goes up (usual+upgrade).
Is it worth it to just get upgrade and pay more, or buy phone on ebay and change phones? Has anyone bought a phone on ebay and had smooth/problematic transition on AT&T network?
