How do i get a Nextel Motorola i710 to work with my Bell Wireless sim card?

I had the motorola v3 razor and it died, A friend let me have his old motorola i710 which accepts the same sim card as my v3 the only problem is the phone has nextel on it, Ive heard of people converting phones to work with there sims, i was wandering the sources and what i have to do to make the nextel phone work with my bell wireless sim card.|||Unfortunately, it's not possible. Nextel uses iden technology to power its phone network. Its not combatible with any other type of service. Your Bell Wireless phone is GSM based and cannot work with that phone. You'll have to check craigslist or ebay.com
