I can certainly understand the importance of the UDP for those who need a lot of mobile data.
However, with the loss of the $450 subsidy, and the impending $5/month price increase, it made sense for me to give up my old UDP, too. I liked the idea of never worrying about my data usage, but in reality, my record month was 1.3 GB. Wi-Fi is available almost everywhere I go. I'm a Comcast customer, and in my area, Comcast not only has a massive indoor Wi-Fi presence, but also has even started putting up outdoor Wi-Fi antennas.
I've switched to the 2 GB MSP, and will save about $4+/month initially - $19+ when my wife's phone comes off-contract. (She's been on the $15/month 200 MB data plan for the past four years, and never went over!)
The "+" represents two costs:
- We never texted enough to justify adding a text message plan (thanks iMessage!), but a la carte text messaging was adding $4-$6/month (worst month $15) to our bill, which is now covered by the unlimited text messaging on the MSP. Added bonus - telling family and friends without iPhones that it's now okay to text us.
- My wife was buying, on a semi-regular basis, the $25/1GB/3 month PAYGO data plan for her iPad, and typically using only 300 - 400 MB over that three month period. Now she can tether the iPad from her iPhone. That should add approximately $80/year to our savings.
