How secure is the OpenAT application once on the Modem ?

Are there security features that I should be using to protect my application ? I can’t find a way to upload the code once on the device, but presumably that doesn’t mean that it can’t be done.

as wavecom doesn’t provide a way to do this, there is no easy way.

there will always be a hard way…  
(i mean, if even Nintendo and Sony etc can’t prevent this from happening…)

and also, security by obscurity is no security at all!

But, when it comes to “obscurity”, Wavecom must be masters…?! 😆

Do you mean there is no easy way to protect my application ? Or no easy way to upload my application from a modem ?
