Help Will Unlocked HTC Thunderbolt work on AT&T?

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!!

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.

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.

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.

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.

HERE FOUND THIS POSTING ATMobile Phone Lover NOT MY OPINION JUST FOUND IT.........

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.
