the 3G bands

3G frequencies

MT15i	HSDPA 900 / 2100
MT15a	HSDPA 850 / 1900 / 2100 / 800

in other words, if you live in the US

MT15i will work with Tmobile and MT15a with AT&T

the i version works with most countries all over the world and the a version mostly the americas

Thank you very much again, uliwooly-wooly! 😃

Do you think there will be any problem if I use a firmare for MT15i on my MT15a? I use the 2100 3G frequence.

you are only using the firmware the 3G bands stay the same. I know that for a fact on other Xperias so if you use MT15i software on MT15a, it will work as an MT15a

Sorry, but incorrect.

T-Mobile uses the AWS band which is 1700 MHz. Not supported by the "i" version nor the "a" version. There is no 3G T-Mobile (US) compatible version. The 900/2100 MHz 3G bands are used in Europe and Asia primarily.

T-mobile USA utilize

2G/Edge 850 MHz / 1900 MHz

3G/H 1700 MHz / 2100 MHz

Since your original reply referred to the "3G" frequencies, it implies that both AT&T and T-Mobile will work on 3G with this phone.

AT&T will get 3G with the "a" version only. T-Mobile will get 2G only with either version.

Hi everyone:

I know this post is pretty old but I'm very interested in a response about this:

It is possible MT15i behaves as a MT15a ?

I am absolutely sure what I need in my country is MT15a band compatibility. So, if my MT15i can be flashed or formatted or something to act as a MT15a, please I need to know what should I do for that.

I am sorry if I am posting in a wrong way or site; please help me to do it right if necessary and thank you in advance for help.

Best regards,
CD

Hi uliwooly-wooly:

I write directly to you because I was looking for an explanation if my MT15i could work as a MT15a and your comment opened a little window to belive that can be true.

Please let me know if MT15i can be flashed or reinstalled or something to work with 3G/H in bands 850/1900 as MT15a does.

Thank you very much in advance.
