Is it possible to change the details of my mobile that my carrier sees? Here is an interesting one. I have a mobile phone that I use daily. I have a PAYG package that allows unlimited Data with it. 

They have just changed their policy that now sees my particular mobile phone as a Tablet. With that they have blocked my Data use via the Sim for this mobile only!

What I am interested in is if there is a way to make my mobile look like another model of mobile to my carrier.

Like this.....

My mobile is a Samsung Galaxy P1000 - I want it to look like a Samsung Galaxy S3 to my network... Hope that makes sense..

I have used this phone for 14 months every day without problems and spoken to my network provider at length regarding the problem. They said if the SIM is used in any other Smartphone it will work, just not mine!! 

Look forward to your answers on the matter..
Your TL;DR; answer is: NO.



Your carrier will always see the IMEI code of the phone. It is like a MAC address on a LAN.

Spoofing or changing the IMEI of a device is Illegal. 

Since in S.E. we won't go beyond the law, nobody is changing the IMEI.

You can check the model and status of any device by its IMEI, in this link here.

The P1000 sits on the boundary between a phone and a tablet (Humpty Dum-P1000 sitting on a wall...). 

There are some like @onik♦ or your carrier that will see it as a tablet, but screen size (and there are several 7 inch phones out there) is hardly enough to make a device a tablet...

P1000 runs only up to 2.3 gingerbread (stock) - Several apps behave as phone only because of that. It makes calls and messaging, so I call a mistrial on this whole tablet or phone thing.

We are specifically talking of the P1000 here. The other generations of the Galaxy Tab series can fall into the tablet side of the wall, but the P1000? no.

Good luck convincing your carrier of either. My money is on them telling you to suck it (as bad as it sounds).
