Suitable Android device for engineering project

Question

I'm working on an Android application that can get low level information from a GSM modem. It depends on sending AT-Command to the modem and receive the answer. The application is done but there seems to be a problem with the device.

Most of the commands return error, that means the modem's manufacturer locked these engineering commands.

I wonder if there is a mobile device that's permit for the engineering purpose and let me send all AT-Commands I want.

note1: my mobile is Samsung Galaxy Win Duos.

note2: maybe there is an other way to get low level info. I saw this link. and it get every thing in GSM modem even L3 message.

Conclusion:

I want a mobile name that run all AT-Command (is nexus work for this app?) or an other way to get these info.

Answer 1

AT Commands What you should know

Different phones support different sets of AT commands. This means that a specific phone might not support all AT commands

Better u try out lower versions since they have less restrictions

You can go for T-Mobile modded phones since they are the ones with very less restrictions
