auto reboot after i put the sim card topic

Dear All,

Please help,

I have purchased the Redmi1s in Singapore, it worked good there,
When i travelled to india, with the indian sim card it worked well.
But now i am in Netherlands, but when i try putting the new local sim card, the system keeps going auto reboot continuously.

Somebody please help me or suggest tips to overcome this.
Lots of thanks in advance,

regards
Karthick
