A 300 MB service from AT&T costs $20.00/m. Go up to 1GB, and it's $45.00/m.
No way this is any less than that... 3G/4G or whatever.
Yeah, I'm inclined to agree, although those are retail charges. My guess is that Tesla was waiting for the AT&T announcement to finalize plans.
While it's fun to speculate what Tesla *could* or *should* do, it's probably easiest to take a look at what their peers are up to and extrapolate from that. Granted, Tesla have done things its own way (mostly), however in this domain they have considerably less control. This is recurring cost to a third party supplier.
I do think Tesla will include vehicle diagnostics and remote access for free. That won't cost them a ton, and they can control the amount of traffic that goes over the network easily (and off-load to WiFi when needed).
Tesla *will* charge for enhanced features such as Google Maps (data hog) and Internet radio access (another potential hog depending on bit rate), and other application access (when other apps come).
Audi connect is anywhere from $15 to $30 a month on
T-Mobile (depending on your commitment), and Mercedes
Mbrace is $14 to $20 a month. It's hard to compare directly because these services differ in some ways, but the basic premise of "internet connectivity" is the same. I expect Tesla to be in the same ballpark (but closer to $30). Tesla doesn't have the same scale as the others.
As far as the network debate goes (who's better), it really comes down to a ton of factors. AT&T makes the most sense for connected car services in the US because of two major reasons: GSM/UMTS and 850 MHz licenses. GSM/UMTS because it's global - the complexities and cost of adding CDMA for 1 market when they can focus the global GSM market, well, it doesn't really make much sense. That leaves AT&T or T-Mobile in the US. T-Mobile doesn't have any 850 MHz spectrum, which means, rural coverage suffers. AT&T has a ton of it. In general, AT&T has much broader coverage than T-Mobile - just take a look at a coverage map and compare).
The question of coverage quality is highly variable and personal. It's about where you live and where you travel. Some will have superior T-Mobile coverage, some AT&T, and some Verizon. Site density, technology, frequency, and network management (generally in that order) dictate what your experience is going to be.
Verizon got a jump start on LTE deployment because CDMA was clearly on its last legs (Sprint got distracted by Clearwire and Wimax). AT&T followed behind, and T-Mobile and Sprint are playing catch up. LTE, unfortunately, is moot at the moment because Tesla's hardware doesn't support it. The Faux-G (4G) marketing mess (thanks, AT&T) makes things a bit confusing for the average consumer (when it's intent was to make it easy). Based on current generation hardware (3G, not 4G), if Tesla chose Verizon instead of AT&T as their network partner, Tesla customers would be stuck on the extremely slow CDMA EVDO network, and not Verizon's LTE network.
You think you have problems today with AT&T? I shudder to think how bad it could have been on Verizon 3G.
On the LTE front,
this article from CNN mentions only 4G (HSPA) from Tesla. I don't have much faith in the accuracy of CNN as a news agency (especially in the technology domain), but it's not encouraging. I'm hoping Tesla just hasn't made the switch yet.
Oh, and one more thing... it's doubtful Tesla will let you pick carriers (I too, would love this), but I'm sure some enterprising folks around here will be able to figure out a SIM swap easily enough (it's the APN settings that may prove difficult to change).
