Network Unlock and old Sagem RC 815 Plus - GSM-Forum

Lantizia · 11-15-2020, 17:28

Hey,

So I've got an old Sagem RC 815 Plus from the late 90's which is locked to Vodafone UK. I was wondering about doing a network unlock on it, so any UK SIM card (where the network operator is in the right frequency of course) would work (e.g. O2/giffgaff).

I've managed to access the third hotline menu using a technique I found online and I've written down the following values...

ram adr 219 nbr 6 :
prom 0 :
prom 251 :
prom 252 :

I thought I could use them with a utility I'd found called 'sgmslck' but when they're entered it just states... "incorrect data entered/retrieved or phone uses unknown SIM-lock mechanism".

Does anyone have any useful network unlocking tools for this kind of device?

Thanks

p.s. I asked Vodafone to unlock it, and after several months they've actually admitted they've lost the technical know-how to unlock it as it's so old.

Steven
