Hi, I’ve changed sim card in my X750 device. After power up I typed new pin (replacing) old one. Unfortunately I received ‘sim card not registered’ error. After putting sim card to mobile phone again I had to type PUK to unlock sim card. It sees X750 locked the new card by trying to use incorrect pin three times.
Shouldn’t modem emit error when wrong pin is set and stop card unlocking with wrong pin?
How to type PUK code from X750 web interface?
