There are a few jailbreak apps on Cydia that let you use FaceTime on 3G: 3G Unrestrictor, My3G, and FaceBreak. If like me you’re on an unlimited data plan, data usage is not a problem. If however you are on a capped data plan, using FaceTime over 3G could take you overboard.

A few days ago, I made a FaceTime call over 3G for 10 minutes to figure out how much data FaceTime uses on 3G. As you can see on the image above, I sent about 15 MB of data and I received about 12 MB. I think I sent more than I received because I was moving around a lot.

Total data usage for a 10-minute FaceTime call on 3G: 26.5 MB. That’s about 2.65 MB per minute.

Obviously your mileage may vary but these numbers shouldn’t be too far from what a FaceTime call over 3G will cost you.

    Well, now I’m sort of wishing I hadn’t been a cheapskate & dropped my unlimited for the $15 package. I’d never gone over 200mb before, so I figured it’d be cool. I guess I wasn’t using my brain on this one!

  • I have owned my iPhone 4 a total of 23 days and in that time I’ve used 364MB up and 5,500MB down. 2GB a month is not enough if you want to actually use the features the phone was designed with. Do you know if Cricket and or Metro PCS are using GSM? If so we need to start lobbying to have service plans compatible with the iPhone. It’s clear AT&T doesn’t get it and never will so we need an alternative.

    that $25 iSpot unlimited plan is looking more and more sexy…. lol

  • And the battery usage isn’t a picnic either, haha.

    Same results I found on my wife’s I4.. I also dropped her back to the $15 plan since she never used more the than 40m in a month in the past. Now we facetime with her on WIFI and all is good..
