In theory - it's possible - there a parameter called MS location and Update location is used from BCC to identify in what BS cell group is placed MS / to avoid brodcasting to all MS units - this will overflow GSM network / - so you need to "cheat" BCC with random / different, old, what you want... / locations ... there will appear one SO INTERESTING thing - if you make this - for sure other side of GSM conversation will not catch your number / like CLIR is used / because you will not exist at all for GSM network
- also your account will not grow up - funny - isn't? - speaking without money

P.S. it's only theory ...
