    I own an HTC Thunderbolt, but I am forced to switch to AT&T. I am able to buy an unlock code for my phone, will I be able to unlock it and it run on AT&T? I would like it to run 3G or better. If you have any info, please let me know. THANKS!!

    It wont work because ATT and Verizon use different wireless technologies. Att being GSM and Verizon being CDMA.

    Different technology. Thunderbolt is a Verizon phone which uses CDMA tech. AT&T phones use GSM.

    Unfortunately Verizon used CDMA technology and AT&T uses GSM for their phones. You cannot use any Verizon phone on an AT&T network and vice versa.

    no it won't work. Like the above post states, AT&T is GSM while Verizon is CDMA. Basically, AT&T uses SIM Cards, and Verizon doesn't. Thunderbolt would work for Sprint though as Sprint is CDMA. T-Mobile is GSM.

    Thunderbolt COULD work for Sprint if they allowed you to swap between. Neither Sprint nor Verizon allow you to take each other's phones to the other network. Sucks, But it is what it is.

    Oh sorry for the misinformation then. I assumed it would work because they are both CDMA and AT&T phones work for T-Mobile and vice versa and I thought it'd be the same with Sprint/Verizon. Either way, your best bet would probably be to sell it. You could always get an Inspire. It's very similar, but a little less awesomeness. No FFC, no kick-stand, a bit different specs, stuff like that. It's a great phone though.

    The thunderbolt does have a sim card so I think it would work on att if it were unlocked?

    The SIM is the Tbolt is for LTE, not for GSM usage. Which is also why even though it has a SIM in it, it's not a Global phone :)

    ^Are you sure? If the TBolt would work on AT&T, I would definitely trade my Inspire for it.

    An EVO 3D on Verizon. Good lord that would be awesome.

    A SIM card is a subscriber identity module.
    Has nothing to do with the underlying radio hardware.
    That is why a sim slot does not mean you can change carriers on all devices.

    I wish it was more like the UK over here in the US. Over there everyone operates on GSM and you can unlock just about any device and use it on most carriers. It sucks so bad that there are two different techs here in the US, and CDMA phones don't use SIM cards.

    I'm on Verizon at the moment, but I'm switching over to T-Mobile because I'll be moving to Canada within the next few months and my DX on Verizon won't work on Canada's GSM network. I wish they'd do away with CDMA down here in the US.

    What's AT&T's LTE rollout schedule?

    I'm sure there would be myriad hurdles, but AT&T's planned LTE protocol is identical to Verizon's, no?

    You should check on that GSM T-Mobile...
    GSM is used for voice and you're probably safe using it in Canada.
    But WCDMA is used for 3G and the frequency used varies. T-Mobile in the US uses a frequency unique to T-Mobile in the US. I don't think you will get 3G data in Canada (AFAIK) with a US T-Mobile phone.

    Since, ya know, LTE is a European invention, it's gunna mean that all that useless GSM turf is going to become LTE. When we're all on Long Term Expansion, the European Telecommunications Standards Institute that owns the rights to the LTE brand will have created one global roaming space.

    I, for one, will /pogo furiously. I may host rituals that repeatedly bury GSM forever, much like what diners at Milliways enjoy.

    Verizon started an open network policy several years ago allowing you to activate a non-verizon ESN on their network. You just need to speak to the right person on getting it added to the network. Its difficult but It is allowed and can be done.

    Only after it's been shipped to their certification factory and certified to work on their network. Of course it still has to be a CDMA device as well.

    There are numerous services provided in the market of cell phone. Along with the large amount of services as well as fabulous freebies for customers, it is a little bit difficult to experience them all. So how can we handle this problem if we are bored with the only one service from our provider? Here is your answer. These unlocked cell phones have come into being to solve all the problems. That’s way the demand for Inspire 4G and the unlocked HTC Thunderbolt has become a chic among users of HTC phone.

    Mostly, service providers are willing to lock cell phones to make sure the exclusivity of usage for their phones only. That is to say, users cannot apply any other SIM card offered by other network providers. Usually a locked cell phone is the practice of certain companies on a brand-new product and it is sold with special offers and enormous discount. Therefore, an unlocked one is available to any GSM providers all over the world. What you have to do is merely insert the SIM card into the cell phone and then fast and convenient phone service is for you at once.

    Suppose you purpose is the flexibility of cell phone usage and you have to change the SIM cards frequently for different usage, I do recommend the unlocked HTC Thunderbolt. Probably, the operations of unlocked cell phones in different versions vary from one to another. As to HTC cell phones and Inspire 4G unlocked ones, they are hassle-free since many providers provide the services in four major concerns of the web. To unlock HTC Thunderbolt, the IMEI number or the serial number is required. It is labeled inside of your phone, exactly near the place where the SIM card is assembled or you can just key in *#06# on your phone. The good news is that no special hardware is needed to unlock HTC Thunderbolt and HTC Inspire. In addition, customers of HTC can get relevant services at the affordable prices offered by certain online companies.

    Once you phone is not locked, you can enjoy the convenience and flexibility of making use of various SIM card. For example, if you consider that the network of one provider is much more advantageous, you can turn to that one anytime without any problem. In the United States, there is T-mobile, AT&T and many other types that can provide your unlocked HTC Thunderbolt with great services. By doing this procedure, the cell phone charge can be cut down to large extent.

    Wow old thread. The simple answer is still no. You can not move a CDMA phone to a GSM network. No matter what you do to the Thunderbolt, you're not going to be able to use it on AT&T.
