I bought a used Nextel blackberry 7100i and I put my boost sim card in and all it lets me do is regular calls and chirp. I can't text or anything. How do I unlock this?

Boost Mobile has the cheapest (and slowest) data service around, and the Nextel Branded BlackBerry is the only smart phone that works with Boost's iDEN service.

The old 7520 and 7100i BlackBerry's can be purchased for around 50 dollars, and are very usable smart phones.

The newer BlackBerry 8350i is one of the best blackberry smartphones available. However on Nextel it costs more then 120 dollars a month for unlimited everything and on Boost mobile you can get unlimited service for $50 a month.

The difference however is that Boost mobile does not offer a Blackberry Data Plan and Nextel does. So if you want to browse the web, send emails, and be able to download apps, you have to convert your Nextel Blackberry to Boost Mobile.

The email works a little differently in that you can set up your yahoo or aol mail to forward to your Blackberry by using the email address

[email protected] as the forward to email address.


What are the differences of the Nextel Blackberry models?




Besides the obvious difference which is the design of the phone and the applications and memory available, the 8350i runs BlackBerry OS version 4.6 whereas the 7520 and 7100i run version 4.1. The older OS does not support as many apps and features.

To sum it up Boost Mobile Phones aren't good and Blackberry's are. It's really that simple.


Does Boost support the BlackBerry?


Not officially. Boost sells their Starter kit to "give new life to a previously used Boost or Nextel phone", but they make no specific mention of its compatibility with the BlackBerry. Using a BlackBerry on Boost is consistent with their terms and conditions, but you won't get any help from Boost for configuring your BlackBerry.


Which features work?


Voice service and basic data service work.

3rd-party apps work, including apps for web browsing, email, GPS, and instant messaging.

Over-the-air installation of apps using the BlackBerry Browser will work if youfollow the how-to.

Text messaging will work if you follow the how-to.

Apps can also be installed using the Desktop Manager software on your PC.

Which Boost plans included data service?

All Boost plans include basic data service

You can get your unlock code for your 8310 from http://blackberrymep.com , it's the best -fast, cheap and 100% accepted codes.

You do not need to "unlock" that blackberry.  If you put your boost sim in it the phone calling and direct connect will work immediately.  Getting the txting and internet to work require you to install other service books.  Try this link http://www.howardforums.com/showthread.php?t=1530734  which explains how to remove the old books and add the correct service book to use mms and internet.

I activate phones for Boost Mobile.

I'm sorry to tell you, but an ic902 can never be unlocked to work properly on any other system - to include the Boost system. Here's why. The ic902 is a hybrid phone. That is, it uses two different cellular systems to operate. Specifically, voice calls on the ic902 are placed over the Sprint CDMA network and Push-to-Talk (PTT) calls are transmitted over Nextel's iDEN network.

Boost Mobile calling (both, voice and PTT) uses the iDEN network from Nextel. Thus, the ic902's radio transmitter (which is CDMA) cannot make calls on the Boost ( iDEN ) system.

Moreover, if you plan to use Boost Mobile, I STRONGLY suggest that you NOT purchase a Nextel phone and have it unlocked to use for Boost.

Although Nextel and Boost phones seem the same - they are not. If you look at the model number of Nextel phones most of them end in a zero. (ie., i850, i870 etc.) where Boost Mobile Phones end with the number five. (ie., i855, i875, etc.) This is because the transmitters in the phones are set to different frequencies for different purposes (like for texting.)

If you go to eBay for example, those who sell unlocked Nextel phones to use for Boost (if they're honest) will inform potential buyers in their eBay listings that their unlocked Nextel phone will not (text, for example) on the Boost network. These unlocked Nextel phones will have limitations when used on Boost.

To prevent problems down the road, ALWAYS purchase a Boost phone to use on the Boost network.

If this information has been helpful, please give me a big thumbs up when you rate my answer.
