    I did see it this morning. My guess is that it being an EU product, its gonna have their 3G spectrum rather than US 3G. I love the concept as well.

    U think the high speed networks are not CDMA, UMTS, WCDMA, HSDPA in the US?

    Sprint and Verizon are CDMA, EvDo Rev A. T-Mobile and AT&T are GPRS/UMTS. Verizon is rolling out WCDMA (true 4G) and AT&T is planning HSDPA (3.5G).

    However, the signaling and the protocols are not the only issues. The US and Europe also use different radio frequencies, two each, layer 1. Most GSM phones, including the iPhone, but not all, support all four frequencies ("World" phones).

    The GSM agreement requires that all GSM operators support any GSM phone that supports their frequency and that shows up on their network. Therefore, if I bring my iPhone to Europe, Orange will connect me but they will bill AT&T for all service at a rate agreed upon between them.

    When I show up on Orange or O2, they send a registration message to AT&T that says "I've got him, is he your legitimate use and will you pay us for his calls. If so send all calls for him to us."

    In AT&T's case, I must have agreed with them in advance of going to Europe. Similarly, if you bring your iPhone to the US, either T-Mo or AT&T will serivce you and charge your provider.

    So far so good. However, here in the US we have a scheme under which one may buy a phone form a carrier at a price subsidized by the carrier, in return for signing a contract of specified duration with the carrier. In this case, the phone will use a SIM from that carrier and the phone will be "locked" such that it will only recognize a SIM from that carrier. My understanding is that most iPhones sold in Europe are unlocked and will use whatever SIM is placed in them Thus, when you bring your iPhone to the US, you may use the SIM that you brought with you, or a SIM from either T+mo or AT&T. However, when I take my phone to Europe I may use only my AT&T SIM.

    For most of the phones that AT&T sells they will "unlock" the phone at the end of the contract or, at their discretion, upon request. AFAIK, they have not unlocked any iPhones. Of course, since the "lock" is software, there are hacks.

    Therefore, with "dual SIM" capability when you come here, you can continue to use your European SIM and also use a US SIM. However, since my phone is locked to AT&T, a dual SIM capability will not help me.

    Another way to think of it is that if one can switch SIMs, the dual SIM capability is useful. My understanding is that modt iPhones sold in Europe are unlocked and will use whatever SIM is place in them However, if one cannot switch SIMs (Most AT&T customers), then "dual SIM" is not useful.

    Therefore, the answer to the question that started the thread is that a "dual SIM" capability for the iPhone will work well with European purchased iPhones but only "unlocked" iPhones purchased in the US.

    OUAOU, thank you whmurray for this long and very usefull explanation

    FYI, europe works like USA, most of mobile phones including Iphone are basically SIM Locked by the network operator (Orange, Vodafone), they pay a part of the phone against a 12-24 month subscription. To unsimlock the phone, in most of case you do it yourself or in a shop (20-30 to unsimlock, can be more for latest mobiles) or wait 6+ month subscription then the operator is obliged to provide you with the unsimlock code for free.
    It is then possible to mix a Orange & ATT SIM card for coming in the US, that's my goal

    Is there easy way to get a prepaid card with internet illimited connections to internet in the US and how much cost such SIM??

    Thx

    Yes. Walk into any AT&T store. A pre-paid card for an iPhone is a special case. The data plan is $40- per month plus a voice plan. Expect to pay $60-.

    There are already one or two phones that feature "dual SIM." Given how cheap it is to do, I am surprised that it is not more popular. As SIMlocking becomes an anti-feature, I expect dualSIM to become common if not standard.

    Two questions ... will this work in a non-jailbreak phone? I have two At&T lines (one for business and one personal). Could I insert both sims and use the same phone for both? That would be amazing if it worked.

    yeah! Tmobile is your best bet. you can get a prepaid card for $6.99 with 10 minutes. here is the thing, you need a regular phone(like a RAZOR) to activate the card(just so their system registers that IMEI) then call to add the $25 unlimited data plan(i have not tried their T-zone plan that is $9.99 but i hear it does not work anymore with the iPhone), then get a refill card and that`s it. if you get the $100 you get more minutes, and they expire 1 year from the purchased day, so if you travel and stuff this is the best way.

    It might if you were paying iPhone data rate on both phones. Plain old everyday AT&T SIM will not work in an iPhone.

    There is a purpose-built tool for cutting the SIM that removes the risk.

    Looks like a workable solution. Does it require JBing? I may buy one of these before I go to Europe in October. I will be gone for a week in three countries. AT&T will charge me four times the value of the iPhone.

    Pay-as-you-go consumers need a high degree of flexibility and control with their mobile finances, and with 3's pay-as-you-go SIM card, no other PAYG service can match the flexibility provided by 3. The SIM card itself is free and will grant the user access to Skype and Windows Live Messenger at no extra cost -provided that you are using a mobile phone that is not sim locked and is 3G compatible.
    international SIM

    SIM flexibility has become more important as Apple's tie to carriers has loosened a little without JB. May become even more so it the iPhone5 is a "world phone." Is a world phone a better choice for Apple than half a dozen different phones for different markets?
