July 7th I cancelled the account I’ve had with AT&T for the past twelve years and embarked on an experiment to see if it was possible to go carrierless and retain a somewhat normal existence. I’m happy to report after 30 days that this situation has worked surprisingly well. This post will summarize the key things I learned over the last month and offer some helpful nuggets of advice for anyone contemplating doing the same.
Context
The goal in cutting my mobile phone service was very simply to eliminate a non-critical expenditure in the effort of getting extremely lean financially while working on our startup. I had used skype on my iPhone prior to the switch and knew that it handled calls well. My concerns were primarily whether running daily phone calls over Skype via iPhone would be annoyingly cumbersome.
My setup
I have an oldschool iPhone 3GS, a Verizon 3G Mifi mobile hotspot (grandfathered in under the unlimited bandwidth plan they used to offer) and the Google Voice and Skype apps on my iPhone.
The Switch Process
I ported my AT&T number to Google Voice for $20. Doing so automatically triggers the cancellation process w/ AT&T. You’ll want to check what your early termination fee is if you’re still under contract – mine was $70 so I more than covered it in the past month. It took a day for the number port to complete during which time all SMS messages sent to my phone blackholed. SMS apparently doesn’t work like email where it will keep retrying to send until it goes through. It took about 3 days before I began receiving SMS after the port. Once completed I spent another $20 to keep my previous GV # as an alternate phone (it was printed on all the business cards I had recently ordered and I like the idea of keeping separate business & personal #’s).
Unfortunately the GV app alone on your iPhone won’t enable you to send and receive calls. You’ll need to setup a Skype account if you don’t already have one and get an online number to be able to forward your GV # to. Skype offers a $3/mo option that gets you unlimited calls in the US. With the Skype number configured as the primary forwarding number in GV I was now able to receive and send calls from my iPhone.
The Good
- The obvious benefit is that this eliminated a $130/mo phone bill.
- There is an undeniable psychological win in saying FU to AT&T.
- I’m navigationally-challenged and rely heavily on the iPhone for directions. The good news is the GPS is a true GPS and works via satellites (the cell tower triangulation is apparently the fallback method when it can’t acquire a GPS signal). This means the location-based features continue to work in spite of not having a cell carrier.
- An indirect result of going carrierless was that I picked up all the benefits of using Google Voice. Transcribed voicemails is an awesome feature that eliminates listening to long messages.
The Bad
Now, the not-so-good:
- You lose the ability to send picture messages over SMS. This isn’t a huge deal and I’m sure there are apps out there that give this capability. I haven’t really missed this – it’s easy to just email photos but if you rely upon sending picture texts for some reason, this is something to consider.
I have no 911 emergency dial. This is an acceptable risk for me but if you have dependents or frequently commute through dark allies, losing this might be unacceptable.UPDATE: apparently 911 does still work – thanks Dave for the clarification. Now I can continue to live dangerously!- Call quality is flaky over slow connections. Skype degrades the call quality when you have poor connectivity. It hasn’t been a problem yet but there have been a few instances when I’m working over a shady connection that I have to relocate to continue a call. The Verizon Mifi has been surprisingly good for calls with the exception of about 10% of the time it just seems to be unreliable. If you have a 4G mifi card I’m sure this isn’t even an issue. The answer when making important calls is to plan ahead to be working over a solid ground-based wifi connection for the call.
- Unfortunately there’s no way to disable voicemail on Skype – this is a known shortcoming and a lot of people have complained about it. So to ensure that GV handles your voicemail the workaround is to enable call screening on GV (formerly known as “call presentation”). It’s only mildly annoying but means you’ll have to answer calls and click the “1″ button to patch the person through.
Headsups
So here are some random tidbits of advice based on what I learned:
- Use Google Talk when in front of computer and save on outbound calls. I went through $9 in calls over the past 30 days on the pay-as-you-go plan. If you have the unlimited plan then this is irrelevant but Google Talk is free for US calls and you can offload some of your paid outbound calls to GT while you’re in front of the computer.
- You need to setup Google Contacts for caller ID to work. This is simple/obvious but you need to have all your contacts loaded in GV for it to be able to associate names w/ calls and text messages. Skype will automatically pick it up from your Contacts in the iPhone so inbound calls should still register with a name.
- If you’re calling someone who happens to have Skype the call quality is way better if you can just use Skype instead of Skype->phone.
- Get the Chrome extension for google voice. It’s pretty slick – it gives you a toolbar button that lets you quickly make calls and check messages.
- You need to remember to launch Skype when you restart your iPhone to keep it running in the background. Otherwise your phone won’t ring when you receive a call- you’ll just get the missed call alert via GV. I have it running on both my phone and computer and will typically just answer via the computer when I’m on it. What’s neat is the iPhone earbuds w/ the mic will work for talking on the computer and actually perform pretty well even in a noisy coffee shop.
- The battery life on the Verizon Mifi is about 5hrs which is not enough to last all day. You should turn it on when in transit and switch over to a local wifi hotspot when you get where you’re going. If you forget and leave the Mifi on all day you’ll kill the battery. It has a USB input so you can get a standard cigarette lighter USB charger if you do a lot of driving.
Conclusion
The bottomline is this setup has proven totally adequate for my situation. There is some admitted flakiness over slow connections and annoyances like lack of ability to send SMS picture messages, but it’s 90% of the service for literally 6% of the price. Ultimately the factors you’ll need to consider in determining whether it’ll work for you are 1) criticality of 911 emergency calling 2) tolerance for occasional call flakiness 3) guilt level for not supporting your phone carrier. In tight economic times, saving $130/mo is significant – I would be re-examining my core business if I were a cell phone service provider. If anyone else has cut the cord and successfully run a similar setup I’d love to hear what your experience has been and if you have any hacks you made that improved it.

Let me explain. I just returned from spending the last ten days at SXSW Interactive and Music. The attendance for Interactive was just shy of 20,000 people and Music this year was apparently about 10x that number. Having attended SXSW three years back the best analogy I can give is that this star of an event has super-nova’d into a Red Giant that’s borderline overwhelming. With such an intense amount of condensed human interaction it’s like trying to drink off of a fire hydrant: you better have a formalized system for taking baby sips or you risk getting your head blown off by the stream. So here’s the three-part “GTD-like” system I used to extract meaning from this event:
At SXSW you’ll meet no less than 20 interesting people each day. These will be folks from all over the world with shared interests and with whom (if you had hours to sit and chat) you would almost certainly find incredible commonalities and opportunities to help each other via sharing contacts/advice/experiences. Sadly you have only limited surface area at an event like this though so you have a tiny window of interaction to make a meaningful connection. 
BTW I hate paper- it’s something extra that takes up space and inevitably you end up losing it. And yet in spite of all our ability to put a man on the moon we still rely upon paper as the lowest common denominator for exchanging contact info at conferences. Go figure.


The two most effective traffic generation activities for me were making physical signs to get foot traffic and doing the Craigslist ads. For signs I recommend the big bright cardstock at an office supply store, a fat magic marker and taping it to a box that you anchor with rocks. Figure out the closest main traffic arteries and place the signs strategically so they’re visible from both directions and so there’s a sign of the same color visible at every turn until they get there. Start early (6am) – you’d be surprised how many people are up at that hour and looking for yard sales (the majority of my foot traffic came before 10am). There’s seemingly a whole culture of people who drive around looking for these signs and scavenging at yard sales. And that leads to the next point:

Next you need to grid out the scene and slice it up. Whatever your individual panel size is (again mine was 8.5″x11″) make a selection box that is exactly that size and put it in the upper-left corner. Make sure that under the View menu both Rulers and Snap are checked. Now all you do is drag the guides from the rulers across to the boundary of your select box. This is a little tedious but as long as you have the snap settings enabled it’s not bad – drag a ruler, then drag the box, drag a new ruler, etc. Do this until you’ve gridded out the entire scene like so:
Now you’ll have some scrap on the right and lower edges. Crop the picture until it has only full panes (in my case a 6×6 grid). If you want to make any color adjustments to the image, now is the time. You can get crafty and use the paint effects if you’re looking to simulate a watercolor or pastel piece of art. Once you have it looking the way you like, it’s time to slice it up. My antiquated version of Photoshop has a slicing tool that unfortunately assumes you only ever want to output .gif files for use on a web site. Gif’s mean unacceptable compression for our situation though so we’ll need to bring the image into Imageready and use the slicing feature there. Once in Imageready simply do Slices > Create Slices from Guides to get this:

Now it’s just an exercise in pain tolerance as you plug ‘n chug through tacking in the rest of the panes. WARNING: now is no time for pride, get a thimble (or a bottle cap if that endangers your ego- some kind of thumb protection). Tacking 150 pins into a wall I’m pretty sure is a twisted form of torture reserved for special criminals – your thumbs will hate you for it (mine do days later). After a solid hour of tacking you’ll wind up with an end result something like:
