Locked phone

Is there any way you can remotely unlock my phone remotely as it is locked after trying to change to a local sim whilst travelling os.  I have tried all my usual passwords with out any success. And my nominated trusted buddie is also os and has roaming blocked so can not send me a text.  Did the password have any requirment for a combination of letters and numbers , capitals ? Or a maximum number of caracters?
