Ok, so im trying to set this up and it says to leave the mcc and mnc blank but if i do that it says it has to be a 3 digit number. Any help? Ive set it all up and still waiting my number to be ported but i cant even use the cell data...it sees the sim card but the bars are still grey. I didnt think the number would have to be succesfully ported to just use cell data. Does it? Thanks for any help!
