GALAXY S 2 TMOBILE frequency.

Does galaxy s 2 tmobile support 850mhz frequency in 3g?
I saw gsmarena that they updated the details and it is supported now, is it true?

This phone supports:
2G: 850 / 900 / 1800 / 1900
3G: 850 / 1700 / 1900 / 2100
Anywhere else that says otherwise is wrong. This is what's printed on the box.

[Q] How to swich between bands?

I need to swich bands to get 3G speeds on my unlocked XPERIA PLAY (R800i), could you help me with this??

It can't be done, on smartphones the radio frequency is hard coded into the CPU chipset, so there is no way to change it.

Are you sure? Acording to GSM Arena it supports the following bands:
-2G Network: GSM 850 / 900 / 1800 / 1900
-3G Network: HSDPA 900 / 2100
HSDPA 850 / 1900 / 2100 / 800
And the bands that are currently working on my phone are: GSM850, GSM950, GSM1800, GSM1900

Are you sure? Acording to GSMARENA the Phone supports the following bands:
-2G Network: GSM 850 / 900 / 1800 / 1900
-3G Network: HSDPA 900 / 2100
HSDPA 850 / 1900 / 2100 / 800
My phone is currently using thos bands: "GSM850, GSM900, GSM1800, GSM1900"
It aslo says "UMTS-BC1, UMTS-BC8" under working bands.

BTW: I found a similar post, wich says that this can be done( On Galasy S )

2G Network GSM 850 / 900 / 1800 / 1900
3G Network
HSDPA 900 / 2100
HSDPA 850 / 1900 / 2100 / 800
Notice how there are two different HSDPA combinations? Thats because its talking about two different models. I know its a pain I had to get the HSDPA 850 model (R800i) to use Telstra in Australia and its actually more expensive.

I have the same problem u.u

[Q]gio samsung modem frequency

Hi, my question is, if there is no way the cell works in the frequency of 1900 MHz for 3G? (WCDMA 1900 MHz)
thanks for replying! .

2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 2100
You're welcome

A 5660M would work on HSPA 1900 MHz...

[Q] Is it possible to turn E980 into E988 or E986?

Hi Guys
My question is related to the LTE frequency they use I have an E980 and I am now in Qatar, the model they have here is E988 which is "LTE 1800 / 2600 - E988" however my E980 "LTE 700 MHz Class 17 / 1700 / 2100” and I am experiencing very slow 4G connection, is it because of the bandwidth or it might be something else.
Thanks in advace
