[Q] Problem with new SIM in an unlocked phone
My i9001 has served me well for over a year and a half, and with 2 different mobile operators (I've had my current one for over a year), but now I want to change, got my new sim 2 days ago and here's the problem : my phone shuts off with my new sim approx. 30 seconds after i've entered the pin code. Had the same problem during summer, it wouldn't take my foreign sim card (for the country i was staying in) and would shut off 30 seconds after i'd typed the pin. The new sim works well on another phone (old nokia). And my phone works well with my old sim.
I used to have CM10 (before that, I used EhndroixII and III). I tried to flash another baseband, then I erased data and flashed back to stock (I9001XEFKP1).
If it is of any use, I'm in France and have used Sosh (Orange) for a year (before that I used Leclercmobile (SFR) for like a month), and I'm now changing to B&You (Bouygues).
The SIM is unlocked as I bought it on Amazon and the seller was German (if that's of any relevance). Also, after flashing stock rom my former SIM card doesn't work.
Also as I was (again) trying to reboot hoping that it would work, the old sim began not to work either (shut off after 30 sec)
Thanks for your help
