Kind of a dead thread, but thought I'd toss in here.
I got turned on to Line2 almost a year ago and was admittedly rather hesitant to start. I started with the seven day plan on a new number, but nobody knew the number, so it was like having a tree fall in the forest. I kept poking at it though and because a friend is on it, started using it more.
A few months later, I took the plunge and ported my main number to it. My reasons were simple: unlimited calls and texts on Line2 were the same price as unlimited texts alone on AT&T. With that being true, why not just give it a whirl and get a free phone number out of it? I liked being able to use my desktop computer with full speakers as a something approaching the quality of a high-end enterprise speakerphone. At this point, LTE had not made it to my home city yet and I had a T-Mobile PAYG account for mobile service.
Making calls from the T-Mobile account and having them appear from the Line2 CID (now my main number) was kind of brutal. I could do it, but not if I was chewing gum at the same time.
In fall, I spent two months in the republic of Turkey and was blown away at what happened. After picking up a Turkcell 3G SIM with data, my calls on Line2 (from Turkey) were amazingly clear. The quality of Line2 has nothing to do with their service and everything to do with the quality of the data. People had no idea I wasn't in the US.
When I got back, I got an iPhone 5 because of the ability for LTE data in my pocket. Once again, calls over Line2 were crystal clear. Because I need tethered data and didn't want to be bothered with the maintenance of a jailbroken phone, I bought the 5GB AT&T plan on top of the basic $40 a month. My bills were about $105 a month plus $10 for Line2, which isn't terrible for that much capability, but it was still more than I wanted to spend.
A month or so ago, my laptop keyboard went on the fritz and I realized I had no backup to work from. I bought an iPad Mini with potential intent to just return it after my laptop was fixed, but had been thinking about the whole iPad-as-phone thing for a long time and thought I'd give it a try, so I got the mini with LTE data. Everything Just Worked as expected, so if I was going to keep it, I had to consider what AT&T was going to do about my existing term commitment on my relatively new iPhone 5.
When I called them, I acted friendly but aloof (the kind of person that installs applications on their desktop, you get the picture) and asked the very helpful AT&T rep about lowering my bill. He said that, yes, I only had used ten mobile calling minutes in the previous two weeks, but unfortunately my billing plan was as low as it could possibly go. So I asked him about removing the phone number to save $40 a month and he said "well, you can do that with an iPad, but not with a phone".
So I asked if I could switch without incurring the ETF. He said yes, as long as I kept the account going for the term of the commitment, I would not incur the ETF. My next question was "gee, what would I do with the expensive phone now? Because it's locked, right?" Amusingly, he said "Well, I'd just put it in a drawer in case you ever need it", but I asked if "my girlfriend could re-register the phone with AT&T" and he said "yes, that's fine".
In other words, at that point, AT&T was not going to unlock my phone for me, but they would not restrict it from being used by a non-family member on a different account. This was key. A few short days later, I had the phone sold on eBay for the same price I paid for the iPad Mini with LTE and equivalent memory.
At that point, he did the configuration change and I swapped the SIMs between the phone and iPad before we hung up the phone. It might have taken fifteen minutes in all.
At this point, for $50 a month plus taxes for AT&T data and $10 a month for Line2, I have 5GB of tetherable data, unlimited text and voice minutes in the US as well as having a tablet that I can carry when I don't want to carry the laptop. Even better, I paid $299 for the subsidized phone, but sold it for the same price as the 32GB iPad mini with LTE. Basically, I got an unlocked and subsidized iPad Mini that is practically unlimited in every regard I need out of it for half of what I was paying to carry the phone each month.
Okay, so this sounds too good to be true. There are some caveats:
- One has to take calls with a BT headset or earbuds.
- Apple hasn't made the APIs to monitor the buttons on the headset or the earbuds public. So even though one is walking around with a dorky headset on, there's no way to use it to answer a call coming in over the iPad that's in your bag (or hang up the call after it's done).
- There is no camera flash on the iPad. Pictures that require flash aren't an option, nor are the flashlight apps (it's back to lighting up a darkened room the old school way with the screen).
- There's no linear motor in the iPad, so there's no setting calls to vibrate. You will be embarrassed at times as your iPad starts making a ton of noise.
- Line2 does not integrate with iMessage. This one is a really annoying oversight on the part of Apple, and it's unclear why they can't allow verification of numbers through an SMS (which Line2 would support just fine).
- The iPad doesn't fit in one's pocket. Going drinking with it is probably a bad idea, but finding your friends without a phone can be a disaster these days.
Some upsides: Turn-by-turn directions with an iPad Mini are a dream. The screen is large and clear and not a nightmare to focus on while driving. Reading PDFs or ePubs is obviously a lot better with the bigger screen. It's a tablet after all, so all that stuff is going to rock. Using Line2 means that one isn't letting Google do voice-to-text transcription of all your calls and treating your personal information as the product being sold. Etc.
Anyway, I hope that helps others in their consideration of this. Overall, I'm pretty happy with the experience and if the downsides don't strike you as a big deal, you'll love the savings and functionality that the setup provides.
