I have had my K850i for about a year now. i have been nothing but pleased. My phone is unlocked, i have only used T-Mobile prepaid with it. I got the prepaid chip out of a cheap 20$ phone you get at walmart. everything was great but i got tired of there terrible rates. I discovered net10. They are perfect for what i need. so i got a cheap net10 phone. I activated it using the phone that it came with. all was great but when i put it in my K850i it says inactive sim. does anyone maybe have any info on how to get net10 to work with my K850i ?
is there a firmware i can load onto it or something?
im not a cellphone guru but im sure there are many on here.

Thanks guys!
