Is a boost mobile sim good in a sprint black berry 8830?

Suggest use the Boost Mobile SIMM card in another Boost Mobile phone.

Try a sim card from a carrier that is not for the phone. If your carrier is boost mobile then use a Verizon or sprint sim card, even a new sim card will not work if it is the carrier locked to the phone. It must be a non carrier sim card.

Your sim card is only "programmed" to work with your current phone and carrier. For example, if you took a windows program DVD and tried to install that windows program on Apple's OSX, it would not work. That sim card is like the DVD. The program for your phone's carrier (since Boost uses other carriers like Verizon, Sprint and AT&T) will not work and may ruin your phone or sim card. Happened to me, so I know.

Yep, the 1776 is a boost phone...you can NOT put a nextel sim in a boost, but putting a boost sim in a nextel works fine.

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.

will not work with boost mobile, (even if it is unlocked) you might be able to use it with boost mobile cdma, which uses sprint service. they no longer advertise this service, but still accept new users. give boost a call and ask them for the boost mobile cdma number

Your BB 8830 from Sprint cannot be unlocked for use in the US.
Check with Sprint before you hit the road just in case. But you can still get it unlocked from here.
