[HTC EVO 3D] RVDigital:
Just wanted to add some updated information and additional thoughts to consider. I have till Oct 9th to make a move. I went to T-Mobile and gathered some info.

First, I should outline WHY I'm doing this. I've been with Sprint a VERY long time. They are far and away one of the best value plays out there. I have two lines between myself and my fiancee, each of us with an EVO 3D. Lately, and even before the 3D, we've had poor/sub-par service with Sprint. Handoffs between towers have been horrible. We even frequently drop calls in static locations. I'm no CDMA expert, but I too wonder if the issue is related to a network that has become even more oversubscribed as of late as someone else mentioned earlier. The final straw for me was the $10 a month 4G charge. I live in Phoenix, the 5 (or 6th) largest city in the nation. As of today, Wi-Max is STILL in test phase, even after stating that we'd be a roll out city nearly 2 years ago. With the latest issues between Sprint and Clearwire, and with Sprints imprending plans to roll LTE, I have litte faith that our EVO3Ds will ever see a significant Wi-Max presence. At 24 months, we're looking at $480 in 4G payments alone.

This post (AMAZING find by the way) has provided a significant oppurtunity for us to look elsewhere. With the Fall 2011 launch of the SGS2, and the current promotion T-Moible is running for the Unlmiited Everything Plan, it's hard to not give it a shot.

As far as the T-Mobile plan vs. Sprint, consider the following numbers.

Sprint

129.98 - Two Lines

Unlimited Voice and Text

Unlimited Data

2 Year Contract

"Instant Discount" on Phone

+$10 4G Data Charge per Phone (2 Phones)

Out The Door Price

Per Phone: 500 - $300 Instant = $200

Plan Price Over 20 Months

149.98 * 20 Months = 2999.60

149.98 * 4 Remaining Months = 599.92

Grand Total = 3599.52

T-Mobile - Classic Unlimited Plus Family

139.98 - Two Lines

Unlimited Voice and Text

2GB of Data

2 Year Contract

"Instant Discount" on Phone

Out The Door Price

Phone: 500 - $300 Instant = $200

Plan Price Over 20 Months

139.98 * 20 Months = 2799.60

139.98 * 4 Remaining Months = 559.92

Grand Total = 3359.52

T-Mobile - "Best. Plan. Ever."

99.98 - Two Lines

Unlimited Voice and Text

2GB of Data

2 Year Contract

No Instant Discount on Phone, Down Payment equal to Phone with Discount on Classic Unlimited.

Out The Door Price

Phone: 500 - $300 (Monthly Installments over 20 Months @ $15/Month) = $200

Plan Price Over 20 Months

129.98(99.98+30) * 20 Months = 2599.60

99.98 * 4 Remaining Months = 399.92

Grand Total = 2999.52

All in all, its cheaper for us to go to T-Mobile. Furthermore, its more cost efficient to take the "Best. Plan. Ever." so long as you plan to stay in your contract. The overall cost of the Phone with the Plans shows almost a $360 difference between the two T-Mobile plans. Best of all, your phone hardware installments are interest free. I dont know how long T-Mobile plans on keeping this around. I would assume most consumers dont do this kind of math when looking it over. One very big point to make here is the fact that T-Mobile has plenty of HSPA+ (42MB/s) coverage in Phoenix and no "extra charge" to have this on the plan. After doing the math, I no longer think Sprint was the #1 value play I always thought it was. Even before this post, I really didnt hink about some of the things I've outlined here. I think the numbers speak for themselves.

EDIT: Forgot to mention our Data use. Both of us are total Geeks, we use "Tons" of data and data intensive apps. My fiancee used 1.7GB last month. I can tell you I use MUCH more in terms of data and data intensive apps. My use (lol), a little over .5 GB. This is thanks to Tasker and my use of profiles that instantly switch to Wi-Fi in locations I've been before. I will be getting her on Tasker from a purely Data Efficiency point of view.
