Hi, i've been using data flawlessly on my z10, until yesterday it stopped working and am getting the message "The SIM card isn't compatible". Everything else is working perfectly, i can make call, send text and even use the wifi. Also my phone is already unlock. Any help would be appreciated.

It's because of data transfer problem generally, not because of Z10 mulfunction nor SIM itself. Most of times it linked with Your data plan with carrier is switched off or never was switched on.
So first step You need is communicate with You carrier techs to check have You any problem of You data plan account or not.
