Is it something new or just instructions for installing roto`s modem switcher?
Can u make calls on AWS?
In canada voice calls are only possible as canadian aws carriers do not have gsm network.

the link to the modem doesnt work. i doubt this will give US tmobile folks 3G and phone tho.

rangercaptain · Jan 7, 2011

I have read so many threads and I need answers.
1. How do US T-mobile users get 3g and phone?
2. Will the modem switcher do this?
3. What is the most current rom to install?

The title is very misleading. It's wether 2g and voice or 3g only made available using the modem switcher.

It will never be like the AT&T that can use 3g and voice. Boo!

He used modem from a cell phone that can do both voice and 3G. The modem switcher is just used to flash the modem but is completely unnecessary, he could have used redbend or heimdall just to flash the modem and be done with it. This is a major win for TMO users.

Can some clarify what has been done here?

The title of the thread claims "for non us users" ... so who/what network is this for?

Here's another link for the JL5 modem.

Yes you are right! but I wished to make modemswitch process more safe for users who do not like use Odin or heimdall flashing several times

No 1700 so that means no 3G and voice on US tmobile tab

It might work for tmobile /wind users as well if somebody can replace RIL libraries / modules with vibrant stuff.

Big thanks to author of thread. It's helped me a lot! A thought that problem im my tablets receiver ^^
But now appeared another problem – leak of battery. During night, in sleep mode it’s discharges on 30% (around).
Can u propose another modem?

nguyenphucthanh · May 4, 2011

Thanks @irkkso for this post and @android-rules for your mirror link. I using T-mobile Tab version with [ROM] Overcome 1.6.3.

Country: Vietnam.
Mobile Carrier: Viettel Mobile.

I was unable to use 3G with phone call but now I have both on my Tab. Thanks so much.

My result: (I don't have a screen shot to show you guys) "H" sign (HSDPA right?) on notification bar and, of course, phone function works!

Thanks again.
