Set Data roaming on/off

Question

How could I programmatically set data roaming on/off in my android application ?

Answer 1

Apologies in advance for reopening a dead post but I have managed to achieve it by calling this executable:

su -c settings put global data_roaming0 1

Also to get the roaming setting for first SIM card:

su -c settings get global data_roaming0

If your app is signatureOrSystem/Privileged app (app resides in /system/priv-app) and your have valid android.permission.WRITE_SECURE_SETTINGS permission in system/etc/permissions. Then you can do it as below.

Enable :

Settings.Global.putInt(context.getContentResolver(), Settings.Global.DATA_ROAMING, 1)

Disable :

Settings.Global.putInt(context.getContentResolver(), Settings.Global.DATA_ROAMING, 0)

I hope that it's not possible to turn on data roaming programmatically as this would be a serious security issue from my point of view ... Data roaming (i.e. UMTS data transfer via a foreign network) may result in a huge bill from your network provider - at least in europe.
