Hi Carol, I sold my 9210I to a friend when I got my 6630 and she just transferred her T Mobile sim card from her old handset to the 9210I with no problems at all. Don't know if that helps any but the sim cards were exactly the same. Cheers, Sandra. ** To leave the list, click on the immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=unsubscribe] ** If this link doesn't work then send a message to: ** access-uk-request@xxxxxxxxxxxxx ** and in the Subject line type ** unsubscribe ** For other list commands such as vacation mode, click on the ** immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=faq] ** or send a message, to ** access-uk-request@xxxxxxxxxxxxx with the Subject:- faq
