Thread: Affordable iPhone 3g SIM Unlock

  1. #21
    Im actually wondering about that too, does it mean you cant use 3G at all, or do you turn it back on after the SIM starts working ?
    It does support 3g but you have to deactivate the feature the first time you insert the sim.

    I have rebelsim which I think is the best one because you can update it and it works with 2.0.1. But even with the new update they have out my problem isn't fixed: if I enable 3g it works but I cannot receive calls. I can call people myself and get and receive SMS. Also I have two rebelsims and one got broken when I tried too hard to reinsert it in the iPhone. I know now that you have to push it a certain way. Also updating the sim can be pretty hard (and risky) because you need the big card inside which your original mobile carrier sim came from the store (hope you understand which one I'm talking about).

    The big idea is that they don't prepare you for all the problems you might have (which can depend strongly on your country and mobile network) but as far as rebelsim goes I can attest from personal experience that it IS legitimate.

    My mobile carrier is Vodafone. Country: Romania.

    Also: do any of you guys have issues with your unlocking sims?

    In the US, T-Mobile runs on a completely different frequency not supported by the iPhone for the uplink, the downlink is the same but it will not switch off between Edge up and 3G down (or at least I don't think it will). I am in a T-Mobile 3G area and it doesn't work.

    In short, in the US, no 3G on the iPhone for T-Mobile USA.
    Sorry,

    Don't worry people..... someone will come out with something... they always do.... what I would like to do is this.... I would like to clone my sim card and use it in my first iPhone..... so I can use both... I feel I am not breaking any law by doing this... as I pay for unlimited phone calls per month..... so I feel I should be able to use both of my phones if I want to..... anyone know of a fix for me?

    I have tested many many sims with different firmwares and patch counts for chris from yessim. My best results for iPhone 3g on 2.01 firm is:

    T-mobile USA Im in AZ
    Using Yessim Fully working edge
    Do not drop service after a few hours
    Been working fully with T-Zones & Push Mail
    Firmware 2.0.1
    Sim Firm 2.4 beta 4C
    Patch count 29
    MCC-MNC: 00101

    3g disabled and data roaming enabled.
    I can even pick up other carriers. I am typing this from VT US

    On a UNICEL network

    I do not have 3g as everybody knows t-mobile does not support 3g where I am and on the same frequency.

    Im fine without it though

    so here is the questions if the 3G signal is not compatible with tmobile why in earth are tmobile customers buying 3G?

  10. #27
    I tried to purchase this from brando, but they cancelled my order TWICE. The sent me one anyways lol. This does work with the iphone 3g on 2.0.1, but you have to have 3g off. Also with data roaming on you get edge. The only problem i had is that i almost destroyed the sim card tray trying to get the sim card back out. I am taking the 3g iphone back until there is a software unlock. Cincinnati Bell doesn't get 3g until later this year anyways.

    that's kinda what i wanna know. i bought a first gen iphone and am a legit ATT customer so i'm eligable for an upgrade to a 3G. but if i get one of those it kills the SIM for the OG phone and i won't be able to use it any more. i want to be able to switch back and forth incase i go camping or if i do something with a greater poss. of it getting broken. anyone know how?

    Default Universal-SIM
    I have just only one thing to say.
    Universal-SIM is the only and cheapest solution for iPhone 3G.
    Their prices start at 3.5 USD at more than 100 pcs and at around 7 to 10 USD / pc at 1-2 pcs.
    So 20 USD as the article says is WAY to much!

    Also check out sohaib.com for new Turbo Sim Technology its 19.99 plus $4.99 shipping. The good thing about this is you don't need to cut your Sim. I bought this for my Iphone 3g and it is working.

    Default Sim Unlock Card Does Work
    The Simunlock does indeed work.

    You may need to use a very small piece of tape on the side that is being inserted and slowly push it in. It will work. I have already tried it using T-Mobile but I had to disable 3G as it will not be available in my area until October 1st. Without the small piece of tape it kind of snags going into the phone. The tape may unroll slightly if you need to remove the SIM but be patient and slowly insert and/or remove the card and you will be just fine.
