Pls contact with Sunsion Technology Co.,limited in China. www.sunsion.com or www.made-in-china.com/showroom/sunsion

The problem is you got the old version tri-band. For US network you need to use a phone with 850mhz. but your n99i is 900/1800/1900MHZ.

    3G network is not okey for the 2.5G phones frequency so...just like if your car takes gas but not water.

The network on the phone is what you need to check you need to find out if it is a quad band or tri-band model.....and what network your simcard works on e.g 850mhz/900mhz/1800mhz/1900mhz

Make sure its not a 3G sim card. The phone doesn't work with 3G sim cards. Try a diff non 3G sim card and see if that works.

MMS TV N99i


Unfortunatly these phones can only send up to (usually) 128kb and recieve up to 50kb. That isn't that big but there is nothing you can change on the phone to make it work. You can resize the pics and try to resend, and have friends send you smaller pics.

This was my major issue with this phone too.
