Nextel i730

hey all! i am new to this phone game. like customizing and all. and i really would like for someone to help me out on a problem. I currently have a T-mobile number and phone, a Samsung t309. I had a nextel i730. So i was wondering if i can unlock the i730, so i can use it with the T-mobile SIM card. If someone can help, it would be greatly appriciated.

can someone please help me!!!???

i dont think it can be done its 2 diffrent networks

no, you cannot unlock your i730 to use your T Mobile sim in it

Sniper is correct. T-Mobile is a GSM provider, Nextel is a iDEN provider.

There are a couple of IDEN phones used by nextel that WILL work with tmobile, but the i730 is NOT one of them. The i920 and i930 will both accept a GSM SIM. That is because it uses both IDEN and GSM 900/1800/1900. The phones must be unlocked to work with tmobile or another GSM SIM. They would work well for Europe, but would not have GSM 850 in the US. If you were only using tmobile PAYG in the US this would be fine because they operate on only GSM 1900. Also, the walkie-talkie wouldn't work with a tmobile SIM.

the i930 wont work properly in the US with a GSM sim in it. it doesnt use 900/1800/1900. its mostly for overseas use...

well there you go, proved me wrong. i have never used an i930 before, and that was something i heard from an owner of a i930. i will have to send him that link and show him he is wrong. thanks roberts!
