[Q] gsm calls ? - Thunderbolt Q&A, Help & Troubleshooting

Rezound has turned out to be a global phone as per this thread
http://forum.xda-developers.com/showthread.php?t=1421341
How about thunderbold ? I don't have one so can't check but would be interested in buying one if this does turn out to be global phone too.

Same radio and LTE chipset, so yeah, should in theory apply to it as well.
The particular phone radio chipsets are known to be capable of picking up GSM bands besides LTE if you go read the tech specs for it around the net. However, if you cannot make a go of it, don't blame me
Also, the sim card in the thunderbolt is larger than a normal sim card. Newer devices like the Rezound and the Galaxy Nexus, have the smaller, standard sim card.

HTC ThunderBolt locked

Hi,
I have bough one HTC ThunderBolt Verizon in America,
I tried to insert my sim card without success, can I unlock it? or is it impossible at this moment?

this post was a fail
the sim card in the phone is meant only for the 4g. the phone is only cdma, not gsm. you can't put the card in there and assume it's going to work.
The Thunderbolt isn't a GSM phone. It uses a sim card only on Verzion for 4G purposes. I doubt it would be useful to do any unlocks on it.
I think this thread is a fail.
I'm nearly certain that as of right now, the Thunderbolt will work on no other carrier but Verizon. MetroPCS flashing isn't really possible since the phone uses some of the new technology to activate itself, the old activation code doesn't work, I believe. And the voice technology is still CDMA, so even if the Verizon bands match up to a Euro/Canada carrier in the future, you'll have to wait for LTE to carry voice, which could still be quite some time.
My sim is 3g, and my operator are gsm/umts but 3G not 4G.
I cannot to use it? If I understand well it works only with operator 4G?
Thanks a lot
Z.
There is a solution to put it on metro and cricket.
Wow, how did you even find xda?

[Q] Sim card support?

Looking at pictures of the Rezound, it looked as if it has sim card support, is there any known way to root/unlock the phone to use on T-mobile/AT&T?? if so i need one...
no the sim card is for LTE only. Sorry! It doesn't have GSM or HSPA support. Only CDMA EvDo 1xRTT and LTE
Ah bummer. Well ill definently have to consider virizon instead of tmobile when i get my own contract

Excuse my ignorance, but just trying to sort this out. Realise it uses an LTE sim card, but as I live in China was hoping to put in a china telecom sim card and use it on their CDMA2000 network (which it does support).
This possible? Thanks in advance.
The sim card is solely for LTE if that helps. It may be possible to flash it to their network but I cannot answer a yes or no
It depends on the spectrum your LTE network uses. The phone should function CDMA only if you or your carrier know how to flash it correctly. Verizon uses a special LTE spectrum range they bought from the FCC known as C-Class if I remember correctly. It was sold after the US went from Analog to Digital TV. There were A-E Class Spectrum and C apparently was the best for whatever reason. I don't know to say anyone on here would know any more info than that in regards to the frequencies.
Thanks, I don't know how to flash it and I assume my carrier probably doesn't know how to or want to either. Shame. Really wanted this phone. It is being sold on taobao here (Chinese ebay equivalent) so maybe a solution will be found in the future.
There is a program called CDMA Workshop that most places in the US use to flash CDMA phones from major carriers to pre-paid carriers. I am sure someone over there could do the same. I lived in South Korea for 2 years, the stuff they could do was ridiculous, and I know China is the same. Actually, my neighbor is from China and is pretty tech Savvy too. I will text him later as he was just in China a couple weeks ago.
He said his girlfriend was able to bring her iPhone from China and have it flashed. Should work the other way around. As far as LTE though, beyond me.

[Q] World phone capability

If the qualdcom processor on the EVO is ment to support LTE which in turn uses a sim card shouldn't that make the phone a world phone I know it is suppose to have an embeded sim. But my true question is will we be able to reporgram the sim once we get root or will write have to go with more of a hardware mod if we wish to make it a world phone.

Sprint uses embedded LTE technology to my knowledge, so its not like on Verizon where there is an LTE sim card. Also, this phone is a CDMA phone, and therefore does not have a regular sim card slot (Like phones on ATT or TMo). No software modifications will change this, and I highly doubt that anyone could even attempt to make a hardware modification to make this phone a world phone. Also, and LTE sim card is not the same as a regular sim card, as they perform different actions (access to LTE and the rest of the network is seperate).
Yeah I was thinking that it does not have the slot the thing is that the processor does support gsm also I was kinda hopeing it was like the rezound it is cdma phone on Verizon. It was found out that just by removing verizons LTE sim card and adding a gsm one it allowed the phone to work as a gsm phone.
the evo lte does not have the GSM and HSPA+ radios to be a world phone
When I preordered, the rep told me it was a world phone. I didn't think she was right but I didn't say anything.
Yeah i read the same post on Engadget i think. What a bummer was hopping it was since it is rocking the same processor that the at&t one (correct me if im wrong). Plus like i also stated was hopping it was like the HTC rezound on Verizon that with a experiment it ended up working. O well .... still kinda wanna take it apart and try wouldn't be xda without some experimenting or moding.
My friend has a Droid bionic which wasn't supposed to have GSM support, but it did through some hacks on rootzwiki and using a T-Mobile sim card. I think that the s4 includes a GSM radio, so its probably possible at least if the sim card can be accessed. Lte is GSM based so it is likely that GSM support is there if software is modified like it was on the bionic.

Sure, you can use it anywhere in the world that has a compatible CDMA network.
Many identify world phone with GSM radios (which the Evo 4G LTE does not have), but CDMA (which it does have) does work well for roaming in Asia.
I've roamed with my Evo 4G across Japan, Korea, and China for both voice and data. There's a full list of countries with CDMA roaming on the Sprint website. As soon as you arrive in country (if roaming works), you receive a free text with the rates and instructions on how to make international calls.

UK/EU release this year?

I see this phone isn't getting released in the UK/EU first, which is..... different!
I would like to know if there are plans to release this device or a similar HTC device anytime this year in the UK/EU region.
I hope HTC it will be available for sale before the beginning of December
I would rather have had the Droid DNA/J Butterfly instead of the One X+ in the UK.
You would think that with HTC's recent financial results, that they would be looking to release this highly anticipated device in many markets as possible.
Does anyone know if the Droid DNA will work on GSM 3G HSPA networks? Obviously the LTE wont work.
I wonder if any of the Frequencies Vodafone or O2 are going to use are the same as the US ones? I do remember reading it somewhere, and I don't think they are the same.

The problem is not the LTE, it is the basic network of the phone. The Verizon network is not compatible with any European network - they use a completely different system as the base which is not GSM compatible. Same reason the Nexus 4 "world" phone works pretty much everywhere except on their network.
Until HTC make a model with different radio chips (GSM standard) this phone will only be for Verizon and a couple of Japanese networks.

From Verizon's DNA specs list:
CDMA1x/EV-DO Rev A, LTE/DO Rx diversity
Global Network: GSM (850MHz, 900MHz, 1800MHz, 1900MHz), UMTS (850MHz, 900MHz, 1900MHz, 2100MHz)
Since it has GSM, will it be possible to use in Europe or Australia?

Yes.. It's just a matter of whether or not it is unlocked out of the box like the Rezound was (Limited at first before update). Or sim locked like previous droids.

Thank you for posting this... I hate when people (read: nexus161) give outdated facts based on the way the tech ran several years ago... vzw has released several devices with a quad band antenna in the past several years. The gsm bands listed are frequencies that all gsm providers currently use at least one of so the answer to the original question is yes, in theory. I'm assuming the international bands are unlocked so there should be no issue using it with a gsm provider, however I'm not sure how vzw has played this in the past so I can't speak to how this will work in practice. My guess though? Similar to the rezound. Locked for first 6-8 months, then an unlock will roll out in an update later.
That's great, so it will work over here. I'm not bothered about 4G yet as its only in a few cities.
I'm new to this whole Verizon CDMA unlocked thing. Can I use a US T-mobile SIM card and pop it into the SIM slot and it will work? What size SIM does it use? Micro?
Do you think it will be possible to buy a Us handset and unlock it?
Will it be 4G enabled?
I just spoke with three different verizon customer service representatives and they all said the phone is locked to Verizon. Two of them said Verizon never unlocks their phones and the last one said devices can be unlocked if you have 90 days of good payment history. Is there a different way to unlock android devices other than having carriers do it for you?

Sometimes... I think you need to have S-Off though... I could be wrong though.
Just because it has GSM support in the radio, doesn't necessarily mean it has a SIM slot! If I'm not mistaken, the Photon Q or whatever the Moto slider for Sprint is has a pentaband radio but no SIM slot...
Anyone got details on that?
That phone have sim slot
That phone have SIM slot, please watch any "hands on" review and you will see that.

It has a SIM card slot due to LTE connectivity.

Great news. Hopefully I will be able to order the device soon from a US eBay seller. That is unless HTC actually announce a UK/EU release before then. But that seems extremely unlikely.

Dual Sim Unlocked Android Flagship Phone?

Hi, I would really like some help picking out a new unlocked dual sim phone. I will be traveling around the world consistently and need to be able to jump on some kind of GSM service in X country. I'd also like to keep my USA based sim card in my phone as well....just in case someone back home needs to get a hold of me. And lastly, I need a phone with decent hardware specs.
So what phone would you suggest? I don't mind if the phone isn't factory unlocked...I've unlocked my Evo, Evo 4g, and Evo 4g LTE phones in the past just fine with the tutorials.
I'd really like something that isn't garbage. I keep seeing these Blu phones, but they are like $100 and seem a bit lackluster on hardware.
Is there a GSM based flagship phone out now that I can simply install a dual sim adapter into, and acquire my desired results?
Just curious what people smarter than I in the phone arena would do in my situation.
I'm using thé HTC zone m7 dual sim and it's work perfectly for me. I' m living un africa
I have same situation as you, but I am not able to find such a phone. There are dual sim flagship phone selling in Asia, however it does not support all bands in US. I may buy the new Windows phone Lumia 950XL from MS store(not from at&t because ATT version is single SIM, but MS store unlocked version is dual-SIM).
