[Q] telephone ID code change
Dear N4 users,
I'm writing here to ask a (maybe silly) question. I live in Italy, and my carrier (TIM - Telecom Italia Mobile) has implemented a certain number of VoIP filters on our data connection to limit tethering and skype calsl on certain monthly data profiles.
Due to this reason, according to the different APN availables (two APNs are available: the first is a wap profile with proxy, and the other one is only for iphone users with no proxy), we have some problem sending and receiving whatsapp images/video or we have delayed notifications.
Essentially, whatsapp is mis-identified as a VoIP program and is filtered by the network. The odd thing is that this problem is present only on android phones: iphone users have no problem with whatsapp, no delayed notifications and no delay in sending/receiving images. If we try to connect to the wap APN we have fast sending/receiving of images, but delayed notifications. If we connect to the iphone-specific APN we have fast notifications, but delayed sending/receiving of images. Thus we think that the carrier activate or not the VoIP filters according to the telephone ID connected to the network.
My question is the following: is it possibile to change the ID of the nexus 4 in some configuration files to fake the iphone ID? If I connect to the online service of my carrier, inside my account details is shown the code of my telephone (LG E960), so this information is somehow sent to the carrier. Essentially I'm searching some kind of "user-agent", not for the browser but for the network.
Thank you in advance and I hope that my a little bit-too-much-articulated-question can be answered.
