Motorola CHARM on AT&T 3G - Android Software/Hacking General [Developers Only]

So I have an Unlocked charm running on AT&T but I only get 2G service. I understand this is because TMobile runs on a different band and the firmware on the phone is of TMobile.
But is there a way to mod some files and get 3G service on AT&T USA on Motorola CHARM?

anyone knows how?

Simple answer is no. The hardware doesn't support the band ATT uses for 3g

And 3G TIM Brazil?
I buy Motorola MB502, but get only 2G in TIM Brazil.
In others (CLARO, CTBC, OI, VIVO) I'm get 3G.
How I fix that?
And... have 'baseband-switcher' to MB502? Because 'baseband-switcher', fix that in my Motorola DEFY.

Fuze use in Germany

Hello everyone. I recently moved to Germany from the US and had my Fuze SIM unlocked. Well today I went to a T-mobile kiosk and the rep told me that I can use the phone for regular phone service with no problems but he didn't think that the US spec Fuze would work on the Internet with their data plan? Does anyone know if this is true? Why would it not work? Does T-mobile in Germany use a different band for Internet that the US Fuze doesn't support? Any information that anyone can provide would be greatly appreciated.
Thanks,

http://en.wikipedia.org/wiki/GSM_frequency_bands#GSM_frequency_usage_in_Europe
for normal gsm
http://en.wikipedia.org/wiki/UMTS_frequency_bands
for umts (3g)
and of cause if you got a non gsm device like a simcardless cmda phone == nowhere
itll work fine for phone and data up to 2g. if you want 3g check if it can do international bands or just us ones.

tmobile htc pro 2 GSM/UMTS Band !!!

hi there
well my problem is that when i choose the band of 850. the phone cant really find my network band......
im from costa rica , and our 3g band is 850.
i used to have htc pro from att and it worked 100%
but now with my tmobile, i really dont know why i cant connect to my 3g network. EVEN that my phone gives me the option to change the BAnd.
T-Mobile's 3G band is 1700/2100MHz. Most of the world is different. If your phone isn't T-Mobile branded, it probably has no way to get on the T-Mobile 3G network.

[Q] Verizon TP2 on Bell Mobility

I've read many post and can't get an exact answer. I would like to buy a Verizon Touch Pro 2 Phone and get it Unlocked and then use it on my Bell Mobility network. If I use My Bell SIM card will I get full 3G connection or Will I get block by any incompatible BAND due Bell Settings?
Thank You to help me with my question.
No. The only US carrier to share the same 3G WCDMA bands as Canada is ATT.
An unlocked VZW TP2 will only work in 2G/EDGE mode on Canada's GSM carriers.
Thank You.
Yes I finaly find the Information (more technical)
Bell use 3G HSPA 850/1900MHz so any other phone that not have these frequency in HSPA doesn't work.

Xoom EU 3G with AT&T in the US

I got a question concerning the european 3G version of the Xoom. I was wondering whether I can use an AT&T simcard in my european Xoom 3G when I am in the US to get AT&T 3G to work?
Nope 10 char
But why not? I mean the european Xoom supports 1900Mhz which AT&T uses for their 3G. So what is the reason it won't work?

[Q] Verizon Razr Maxx HD LTE in Canada?

Hi Guys,
So I got a new Razr HD from Verizon, and took it to Canada where I live. I travel a lot from the USA to Canada. The phone specs seem to indicate that it has all the bands necessary to support all the GSM and LTE bands as well as CDMA when in the states. I was able to easily get 3G/H+ service from Rogers in Canada by simply changing the Network Mode to GSM/UMTS instead of Global and then adding an APN for Rogers. However, I cannot get LTE service. The LTE choice seems to be bundled with CDMA LTE/CDMA but I don't think that matters, I think its just a radio choice. However, when selecting this, I get an error from the phone saying "No LTE networks could be found" and Do I want to switch to GSM?
This is sad because the phone would be excellent on LTE. Does anyone know how to get a Verizon branded phone to run on Rogers LTE?
If you have any ideas let me know, I will test them.
Thanks,
Blue

Short answer, you can't. Different LTE bands. Rogers is 4 and 17, Verizon is 1, 3, 5, 13, 25. No overlap, and no-one currently makes LTE hardware that supports ALL LTE bands.

Just wanted to add to this... I tested my Samsung Galaxy S3, a generic version that I got from Amazon, works on AT&T in the USA on LTE and in ROGERS in Canada. Too bad the Verizon Droid does not support a similar global LTE band. Or does AT&T and Rogers simply have the same LTE bands???

Yes, AT&T and Rogers have maintained the same bands since they were partnered maybe 10 years ago. Fido is owned by Rogers, so it also uses the same, from GSM up to LTE.
Neither AT&T or Verizon use "global" LTE bands, because there aren't any. Almost every country/provider uses different bands. There's some crossover, but with LTE, buy a phone for the market you are in, because you probably couldn't afford the roaming rates abroad anyway.
Hey guys, I think I have a related question.. maybe you guys can help
I live in Toronto and Rogers is my wireless carrier. From my understanding, Rogers operates on band 4 (1700 / 2100 mhz) as well as 2600 Mhz.
I am thinking of gettnig the new DROID MAXX from Verizon. I have tried asking the Verizon / Motorola reps about whether the LTE would work in Canada but wasn't able to get a firm answer.
From the Motorola website, however, as well as from gsmarena.com, it looks like the DROID MAXX will have access to not only LTE 700mhz, but also at 1700 and 2100 mhz.
What are the chances that this phone will work on Rogers LTE?
Really hoping it could work out... let me know if you guys have any ideas..
