Hello my name is David and last week I have been in Seoul and I bought a samsung galaxy note 10.1 and I want to know if is there any problem to use with a spanish sim card. I know that I can not use with 4g because the bands in spain are different from korea but I would like to know if I could use in 3g mode? I don't have problems with wifi.
Moreover, now I am in Malaysia and when I put the sim card in the tablet appears an a message that says something like that: wifi oz failed... and then failed authentication...and appears and dissapears continously.
Can someone help me and say me which is the problem?
