Gsm or cdma?

Ok I have a tmobile us g2 I'm lookin for the latest radio to flash with my supervillian Rom. But they say make sure its a gsm hero not a cdma..... how do I know witch I have?

You can rest assured knowing you have GSM..

Your looking in the wrong forum i guess... You say 'GSM or CDMA Hero' (Hero is also a G2 Touch... ) don't flash either of those radio's you'll brick your phone.... I think

this is the forum for the G2/Desire Z (HTC Vision), not the G2 Touch.
the G2/Desire Z comes only in GSM versions afaik...
and just for future reference as you go along. Typical CDMA devices do not have a sim card (unless they are global roaming on GSM). GSM phones have a SIM card.

Thanks guys!

WCMDA is one of the air interface standards for UMTS (so simplistically, it signifies the 3G radio while GSM represents the 2G radio).
WCDMA is a completely different standard than CDMA (and actually competes with CDMA's 3G successor, CDMA2000).

[Q] If I simply Root the G2 does that allow me to use with AT&T SIM card?

Pretty much what the topic says...
My wife has a Tmobile G2... I want to move her to my AT&T plan... but she DOES NOT want to loose her G2... that thing is her baby.
So would Rooting her G2 allow me to run a AT&T SIM card through it?
If not... how would I go about unlocking it so it could?

Yes, it will.

^^ I know for sure using this method will unlock the phone. It's the one I used and it seems to be the easiest especially if you don't know adb too well.

1) Choosing the right option in gfree will allow it.
2) Just making sure you're aware - if it's a T-Mobile G2, it won't work on AT&T's 3G frequencies, so she'll always have either 4G or 2G.

Huh? According to quite a few people the G2X is the only 4g phone that can utilize atts bands..because its quadband..I don't think this phone. I could be wrong but I'm pretty sure this device will only allow connection to edge

The T-Mobile G2 WILL NOT get have a 3G connection with AT&T. The G2 does not have the proper HARDWARE to connect to AT&T's 3G/4G network as far as I know. Only the Canadian Desire Z or (maybe) the Euro Desire Z have the proper Quad-Band radios that would allow for it to get a proper 3G connection on AT&T's network.
If she can live with 2G speeds, then it won't be a problem, simply SIM-Unlock using the gfree/rage method and away you go!

Whoops, my mistake.

I second that. And no simply having root is not the same as sim unlocking.

The method I posted above will unlock your phone. Tried and tested.

Sorry to burst your bubble but the g2 will NOT work. The g2's 3g band is based off t mo's specific dual frequency set up (one for uploads and one for download). Att uses only 1 frequency and it's completely different from tmo's. If youre going to ask me which one, i dont remember but a quick wiki will answer that.
So, sorry, you'll need to get her the desire Z from bell (A7275) not the G2.

Your right. The way I look at it, if your gonna root you might as well go all the way while your at it.

I have a G2 that I swap from tmobile to att all the time. 2g sucks but at least there is wifi pretty much everywhere

Rooting will not unlock it. You MUST make sure that Gfree unlocks the CID - then you're phone will be unlocked to another GSM carrier, however, will not be capable of 3G/4G on their networks.

You could leave the 4g off this statement. Att doesn't have 4g, despite what they are trying to pass off as 4g

4G is HSPA+ though
Both Tmobile and ATT have it

Hahaha.....no att doesn't have squat for a network
Tmobile's 3g is faster than att's "4g"
Sent from my atrix

the 4G that the carriers are calling right now is technically 3.5G. the ITU was pressured to lower the original specifications from LTE Advanced to the current so called 4G.
HSPA+ still isn't really 4G. It's simply forced to be called 4G thanks to carrier pressure.

unlocking your phone will allow you to use any simcard. Cost 25$ for unlock code if you dont have it

UK Bought DHD usable in Canada?

Hi
I have had my DHD for almost two years. I've mow come to canada for 2 month and was wondering how I can get TELUS aim card working.. no signal is found. It worked ok on multiple UK networks.
Do I need to do more than root. My phone?
Many thanks
Sent from my Milestone using xda app-developers app

It will work if its carrier unlocked. You just need to get a TELUS sim card at any telus in canada. Hspa speeds wont work though because European desire hd uses 1900/2100 MHz and here in north America is 850/1900 mhz.
Sent from my HTC Desire HD using xda premium

I've tried it but no signal was found. It wouldn't connect. My brother thinks it could be hardware. Im using this milestone at the moment which works great on TELUS.
Sent from my Milestone using xda app-developers app

Update:
It's still not working, help would be great!
The APN settings seem to correct for TELUS, however, the only networks which show are Rogers Wireless. The phone still doesn't find TELUS when scanning for networks. Anyone have any idea's?

Could be as simple as the Sim card. Sometimes for what ever reason it just doesn't work and getting a new one helps.

It works fine in an older phone.

You should still try a new sim. Little example of what happend to me
I gave my sister my old iPhone.phone was fully unlocked. Her sim worked in her T-Mobile phone but not in the iPhone. My brothers tmo sim would work . We picked her up a new sim, problem gone

Doesn't seem to make a difference. I think it's to do with the Band Frequencies as I have a UK phone. Would it be because I'm on ICS at all? I've flashed a TELUS radio too which didn't help.

Well you would only be able to get 2g in north america. But now that I think about it I believe telus 2g is cdma then if so theirs nothing you can do
OK I looked it up and telus 2g is cdma. Somebody had told me this on xda a while back but its been so long I forgot about it. Unfortunately you can't use your dhd on telus,though their are other GSM providers

Ah okay. That sucks but thanks for the definitive answer

If you have an att logo, then I am afraid that it is an inspire 4g and not a dhd. So, probably you won't have 3g on,Europe. Make sure in about phone.

that does not exist. Dhd is not att branded, inspire 4g is. Changing radios won't solve the issue, because it is hardware issue and not software.

I am not sure, but if the device has an att logo at the back, is definitely an Inspire 4G. You can set that to say Desire HD in about phone if the phone was rooted by modifiying the build.prop.
Check your apn setting with your carrier, if it is well set and you have no 3G, then ask the seller.

[Q] 3G not working on my DHD/inspire 4G

hi, I have installed JT R30 by RB on my DHD but 3G is not working. checked the APN setting, but no luck. do I need to install any Radio for 3G to work? right now its 12.56.60.25U_26.10.04.03_M. plz help. it did not work with ICS by blackout. :crying:

Whether ur phone is Desire HD or inspire 4g and are u from india. If inspire 4g, then 3g won't work in India as the inspire uses different network bandwidth than present in India.

hey OP, welcome to the forums.
I would change your username as it is your googlemail account and can be used for malicious purposes.
Secondly I don;'t believe that the IG4 works in India
Third, have you tried a different ROM or a full wipe?

Inspire 4G works like a charm in India including 3G. I have used it. Please mention your carrier. Many 3G carriers are providing connectivity problems in India right now.

Airtel does not have its own 3G footprint in Gujarat, it connects to !dea cellular 3G when a subscriber attempts a connection. Try a different 3G SIM of Gujarat like !dea or Tata Docomo.

There is difference in Network
HTC Inspire 4G
HSPA+ 850/1900MHz
GSM/GPRS/EDGE 850/900/1800/1900 MHz
HTC Desire HD
Europe:
•HSPA/WCDMA: 900/2100 MHz
•GSM: 850/900/1800/1900 MHz
Asia Pacific:
•HSPA/WCDMA: 900/2100 MHz
•GSM: 850/900/1800/1900 MHz
So if you have Inspire 4g then you will not get 3g network in India.
