I got this brand new bb 7100i about 6 months ago but i did not add the blaberry plan until now (nextel didnt know i had a bb of course) but when they put me the service they told me that i needed to get the bb sim card because some of the features in in the web browser wouldnt work, actually alots of them r not working. WHERE CAN I GET A BB SIM CARD, the nextel stores do not seem to know either. plz help me

No such thing as a "blackberry" SIM card. You need a Yellow 64K card from any Nextel phone.

does it necessarily have to be yellow? mine is white, and i thought the capacity was bigger than 64k

Haven't seen a white Nextel SIM before. Is it grey? Those work as well but they don't support MMS messaging.

well damn i knew that that is what customer support told me but I did notice how hotmail wasnt working, they havent upgraded it my account yet because they said i needed a "blackberry sim card" , i get errors when i logging into ebay, it says that i have to upgrade my browser (which it didnt the first day i sued it), well thank you i will call again....how bout the 128k sim?
iLOVE MY BERRY THOUGH

I Called Nextel And I Told Them That And They Said Well Maybe They Meant A 64k? Wtf Whatever So Then I Switched My 128k To A 64k And Everything Worked Amd So Hapy Now My Nextel Is Full Force !!!!!!!!!!!!!!!!!!! Thank You Blackberry Forums Is The Best!!! Thank Southwestcomm

What, wait a minute. You downgraded your SIM and it worked?

Nextel has multiple flavors of SIM cards. Some work better in BBs that others do.

yes but i thinki it had something to do with the options of the browser too they werent checked but according to nextel bbs r suposed to work with 64ks but now i will never now until i get more than 300 contacts because they switched my contacts to a 64ksim card so i rather just stayed here is a pain to changed it back (not really but...i had enouhg problems plus is working full force right now)
