Yesterday marked day number thirty since I posted my walk-through on how to use your iPad 3G ‘s Micro SIM in an iPhone for data only service, and more importantly its been thirty days since I last used AT&T’s voice service to make a call. While I’ve been using only VoIP to make calls and send texts, I did leave my service active until June 1st just incase things didn’t work very well. But as of the first, I am no longer paying for AT&T voice service.
As you might have concluded from the canceling of my service I’m happy to report, that at least in my neck of the woods, using data only with Google Voice, GV Mobile, IPKall, Backgrounder, and Acrobits Softphone has been a smashing success. While I admit that it’s not as straight forward to place calls, it’s still easy to receive them. Which fits quite nicely with my phone usage.
Overall call quality was surprisingly good, naturally it worked better over WiFI, but it was more than passible over 3G. Over the course of those 30 days I only used 291 minutes of talk time, but I sent over 1,000 texts and used over 16GBs of data streaming content. I also installed MyWi to use my iPhone as a hotspot so my iPad could still browse the net from anywhere I had 3G coverage.
How my setup works is simple(ish). IPKall provides a SIP number for my Google Voice account to call, which rings to Acrobits Softphone, so if I use GV Mobile to dial a number it then rings my iPhone via that IPKall SIP number. Along those same lines, anytime someone calls my Google Voice number the call rings through to my iPhone using Acrobits Softphone. You can find instructions on how to setup SIP calling in this post.
Texting is handle through Mail.app as I have Google Voice forward my texts to my email. For a more real time texting experience I used Boxcar configured with my Gmail account to push notifications of text messages and new voicemails. I can also use GV Mobile or Google Voice’s own website to send texts from my phone.
I did try all of this without jailbreaking my iPhone, and while it works, I wouldn’t recommend it. It’s a bit more complicated to do things like make calls or even answer them (opening Softphone is rather slow). Plus, jailbreaking was necessary in my case since I wanted to run Softphone in the background and completely remove Apple’s Phone.app from the phone so it wouldn’t continue running and using memory (be advised, this removes your ability to call E911 in an emergency).
I will admit this option isn’t quite as appealing since AT&T decided to change their iPad data plans, but for those lucky enough to still have unlimited data it might be worth a try. I’ll likely post another update in 30 days or so, as I refine the process.
