Lumia 640 Dual SIM TE - Field test ##3282#

[zeb066]

Hi,

Does anyone know if there is a firmware that supports the field test in WP8.1? The phone is L640 DS LTE.
The menu can be accessed by dialing ##3282#.

Thanks

is it the ATT branded version?

I was able to do the field test on the T-mobile version but I didn't try to change anything.

I just joined Insider on my T-Mobile branded 640 (.318) build and I had no problem going to the field test.

Mine is dual sim , unbranded - so I'm not sure it will work
