The keyboard doesn't work well

When I Switch on my clock (it has a SIM card) I have to type the code, but there are a zone of the keyboard that it doesn’t work well, then it is impossible for me use my smart. But if I remove the SIM card and I use other keyboard, there isn’t any problem because it isn’t the initial keyboard.

is it a sim pin code? if so… please use your sim in regular phone, disable sim pin… and then use on lemfo … I hope you will not have to enter pin on in watch.

Thank you
