    Exclamation problem with IMSI-Sprint Sierra Wireless 250U USB Modem 3G

    Hello youth ..
    I hope to found solve for my problem here ..
    i have Sprint Sierra Wireless 250U USB Modem 3G/4G.
    i need to flash it to other CDMA carrier.
    every thing are OK ...
    16 digit pass, MSL, PRL, 3g configuration..
    but the problem when i want to write IMSI by using different programs ..

    for Example..
    my MCC:421 MNC:03
    my IMSI that i need to write it is: 421-03-100-xxxxxxx
    i know it's different number but it's not a US carrier.
    when i want to write 421-03-100-xxxxxxx it's changed automatically after restart it to
    421-03-400-xxxxxxx and all 3G user ID configurations reverts back to as the photo in attachment.

    the problem is in area code only with (100) it's doesn't accept it, but when i change the area code to 200 or 300 or any number like 421-03-200-xxxxxxx it's accept to write and save it without any problem and the 3G user ID configurations doesn't reverts back to it's stays with

    if you can help me to solve this problem really i'll be grateful to you..
