I would like to unlock my Siemens CL75 and Samsung SGH-E900 phones - both locked to Virgin Mobile. I bought these many years ago and no longer have access to the virgin mobile sims.
Well you would need to try Customer Services.
However, if they have to get the unlock codes via the manufacturer there may be a problem if they are not available, especially the Siemens who have long since exited the phone market
