    Thumbs up iPhone 4 IMEI / Buying Overseas

    I have an iPhone 2G and got it before AT&T forced all smart phones into a data plan. I live and work surrounded by Wifi and I do not need to pay $15 +tax+surcharge ($30) a month for data, I rather get unlimited Text.

    Now I have two questions:

    1) I am not sure if is illegal, but is there any way to use the IMEI of my iPhone 2G on an unsubsidized iPhone 4?

    2) I am traveling overseas soon and where I am going they sell unlocked iPhone 4s, If I buy that iPhone 4 there does AT&T going to know that I have a smart phone?

    Thanks in advance,

    P.S Please note that I am not debating whether or not is worthless to have smart phones without data plan. Every individual has his/her own circumstances. $30 USD a month for 2 years is a lot of money for a service that I am not going to use.

    1. NO way you can do that ... Also messing around with IMEI is illegal in most countries

    2. If you buy a factory unlocked iphone then you can use any SIM with that phone. If you choose to use ATT SIM with it (such as PAYG), that will be ok as well. However, if you have an account with ATT and decide to use ATT with your factory unlock iphone, ATT has the ability to audit their system to find out what phone you are using and they can slap the data plan onto your existing line. Their policy is that if you use a smartphone, you must have data plan regardless of you using it or not. Finally, the $30/month plan is no longer available. They can add a $15 or $25 plan ... YMMV

    mmmm... I was unable to find law for the US about IMEI change, however, you are right I shouldn't be messing with the IMEI. I rather change phone company.

    About AT&T auditing their system, I don't know since my cousins bought smartphones (not iPhones) from New Zealand and AT&T is unable to determine what phones are they. So I was thinking if I buy the iPhone 4 overseas then the only way for AT&T to know is if Apple supplies them with all the IMEI for the iPhones being sold world wide.

    All the hoops that I have to go to save $720 in 2 years.

    IMO IMEI tampering is illegal once there's a U.S. court ruling that declares it so. Otherwise - while there may be FCC rules against it, I can't imagine it being a crime.

    That said, AT&T knows iPhones, I am not sure how.

    I used my 3GS in the USA - purchased legally in Thailand from the official Apple partner here. Thailand iPhones are factory unlocked.

    In the USA, I popped in my GoPhone SIM and purchased the (insanely expensive) $20 / 100 MB data plan. Only data didn't work. There was no way to get it to work either. After spending literally an hour on the phone with tech support, it still wouldn't work, and they couldn't tell me why either. They could tell me that they don't offer prepaid plans for iPhones - but I had bought this prepaid plan before that policy was in effect, and also I didn't use an AT&T iPhone at all. So what's it to them?

    But apparently they don't want me to pay $20 for 100MB of data. Oh, well.

    I'd just switch to T-Mobile or SimpleMobile if I lived there. For my purposes, short visit, I am going to use Mrsimcard.

    The first 6 to 8 characters of the IMEI is the TAC, this identifies the manufacturer/device. The rest of the IMEI is unique for each device. I am sure with the partnership that Apple and AT&T have that AT&T have a database of all iPhone TACs (worldwide) and compare this with IMEI they see registered on their network. Really quite straightforward.

    Angry So then need to switch

    I ordered a T-Mobile pre-paid sim to test the waters and I have signal only in the parking lot at work. So I guess I may have to give up on the iPhone for now and get another device.... I am considering a Nokia or HTC.

    It is very frustrating trying to get an iPhone 4 w/o dataplan and now I only have bad blood with AT&T. Just wait until I have another option and bye bye At&t.
