    Question Convert a 2g phone into 3g or 4g?

    That's a weird question that popped into my head when I read about 2g/gsm essentially having shut down in canada, with rogers the only carrier still using that network.

    I'm a weirdo who loves old cellphones (I'm planning on getting a nokia 3330) and I've been wondering, would there be a way to mod those old phones into using 3g and/or 4g frequencies? I don't really care if it'd require soldering skills.

    I used to know engineers that might be able to do this. I estimate the project would cost nearly a million dollars of time and materials, mostly time. It is a pointless exercise. You can buy a 3G phone for $10-$20.

    If you want to home brew a cell phone for fun, buy a Raspberry Pi and the other needed modules. You can hack together a bad cell phone that is worth $0 plus bragging rights.

    You missed the point by a mile here. I know I can get a 3g phone. What I asked was if I could take a 2g phone (again, not 3g) and turn it into something that worked on modern networks.

    And you missed the answer.

    You obviously don't understand mobile technology/electronics if you are asking this question.

    Whats this 2G to 3G converter app I've been hearing about elsewhere? Is it actually converting it to 3G or is it just altering the existing 2G connection?

    OP: a phone is primarily a piece of integrated circuitry; it's not a big pile of discrete components like old fashioned radios.

    You'd literally have to reverse engineer the operating system to support the new technology, get an entire new board that can somehow fit inside of the phone with 3g or 4g, and somehow run nokia's operating system on the new board. You can't just put a 3G sticker on the phone and make it 3g.

    I don't mean to burst anyone's bubble. But I am an amateur Research and Development associate. We have been taking old tech and revamping it, mainly in the camera and lighting world. But this exact same topic came up recently, and we think their may be an answer.

    It's a GSM converter box that you would have to take with you everywhere you go. The old 2g GSM frequencies are in a sense "Daisy-Chained" through the converter box. The modern (real) SIM card goes into the converter box and can also act as a wifi router from the SIM broadband signal. The Converter box can also accept calls and activate the then dummy GSM 2g signal from the outdated phone, relaying the information.

    This device would also work for All old phones that didn't even originally have the correct frequency band to be used in the United States (1900 band for US, others for global usage, ect). So the possibilities are basically endless.

    But It would require having this mobile device likely plugged in at home, with a range of possibly 500ft or something like that, and then bringing the device with you (charge-able), on the go.

    We are still in development for this product, but if you have any suggestions, please let me know. Thanks

    Yes, if you consider it stupid to activate old rare/vintage phones (kind of the whole point of the Howard forums by the way), on modern 4g lte networks.

    Honestly I can’t believe you just said that. If that’s true, why are you on this forum, so you can brag about old phones you bought that you will never actually use without a proposed device like this? Hmmmmmm......thought so.
