My friend just sent me this tweak via facebook and I was like good knowing this trick early enough before it starts spreading .
Now this is the way to get this 2go multiple unlimited credits
Just
Get any glo sim card which is already registered ==> create if
possible a new 2go account with that glo number ==> load 100 naira
worth of airtime or above into the glo line==> type 2go credits in
your message compose and send it to +35350 ==> then keep repeating
this last step and see your go credit bubbling up.
N/B.
tip 1 : ten (10) naira will be removed each time you send the message
tip 2: you can transfer the accrued credit to your main 2go account thereafter
