How can I get a 3G signal on ATT or Tmobile Carrier in USA? I was able to get 3G signal in Asia.. Why not from ATT or Tmobile..?
Any hint to fix this ?
Because they are both using 3G bands that aren't supported by Desire S. You can't do anything about it.
Hi, everyone, I am new here in US, and have got an sim card from AT&T. But when I put it into my Nexus s bought in Europe, it cannot work in 3G mod. My phone is i9023, and the radio, or so called baseband is I9023XXKD1
It is already unlocked, and I am wondering if it is possible for me to let it working in the 3G mod of AT&T by flashing a new baseband. Does anyone know? Thank u

Unless your Euro Nexus has 3G on the 850/1900mhz bands (AT&T 3G bands), you won't get 3G on AT&T.

If this phone is anything like the orignal nexus one networkwise, it should work with T-mobile 3G.

correct to both of the above replies
I have bought a Verizon xoom 4g and brought it to the emirates. the network here is 3g and it will not activate. Is there any way to make it work on this netwok ?
It is not 4G or 3G but CDMA technology.
This is not GSM unit that works everywhere after unlocking.
Hi, I bought the defy about a month ago. I bought it in south america. I live in Italy, so, when I came back, and tried to connect with my phone to the 3g network it didn't, just the GSM (the little G on the top). I'm currently using CM 7.1, but with the Defy+ ROM it did the same. Now here's a strange thing: i searched over the internet and find out that with the Defy baseband I could change the band for the Italy one, but, I'm vodafone, and the network with Italia RT on the baseband says Emergency calls only. So I used the International RT, and it worked. I thought it may be the device, so I inserted a TIM chip, but now instead of GSM I get EDGE. WTF?
I know vodafone uses 900/1800/2100...any ideas? It is possible that because I bought it elsewhere I can not connect to 3g in europe?? (even if the defy's manual says it works on Quad band GSM with GPRS/EDGE (850/900/1800/1900 MHz in all regions)
Dual band UMTS with HSPA+/HSUPA (850/1700/2100 MHz in the USA, 900/2100 MHz in Europe, and 850/2100 MHz in Australia, New Zealand and Thailand)??
Thanks for the help!!
Please, help me get my 3G back!
No one can help me? Even a hint would be great.
Thanks

Use baseband switcher dude

As I said before: I used baseband switcher, but it doesn't change anything. I wonder if the 3G fixes on other forums are the same as baseband switcher

for 2G networks, Edge and GPRS are the data connections available.so G is for GPRS not GSM. E is for Edge (both E and G are GSM 2G). some networks have GPRS and Edge depending on the location, some only operate GRPS, it depends on the priority network planning etc..
when you tried different SIM cards you used different networks and thats why you have G or E, depends on whats available for that network in that location.
as for 3G, what country did you buy your Defy?
italy has : 900/1800 for GSM and 2100 for 3G/UMTS
south america:
-brazil has 2100 and other bands for 3G/UMTS depending on region/operator
-other countries in south america have no 2100 but only 850/900/1900
good article here on wikipedia

sadly the 3G radios in most phones are carrying one and not all frequencies so your device is as small and cheap as possible.

Does that mean that even if I use baseband if my phone doesn't have the 2100 will not work in 3g? I bought it in colombia. Thanks for the answer btw. There's any mod, way to give my phone the 2100 frequency? Maybe changing a hardware part? O just I should change the phone? If I change Rom does it do anything? Sorry for all the questions

In the box says made in brazil. Don't know if that's of any help. Any way I can change the 3g radio??
changing roms or baseband is of no use unless you have correct radio. did you use the phone in colombia? did 3G work? if 3G worked in colombia it will not work in Italy, if thats the case i think easiest is to change your phone if you want 3G, not sure if anyone tried to mod radio.

Yes it worked there. Well, thank you for the help, I think I'll keep this for a while, but at the end I'll have to change it. I'll try to ask if maybe some other company use the 850 or 900 here also for 3G. I think, if the topic is solved. Thank you nolimizz.

Hi. I'm from Sri Lanka and I bought a HTC 8x from Canada. It's had Rogers network.. It is unlocked. But there's no 3g in sim settings. How do I get 3g option on my phone? I'm using 2g. Help me please..
3G is a different technique than LTE.
LTE supported phones have a different modem. So 3G is not supported on you're phone model.
