SIM Card Problem

[robertmost]

Hello,
I am new here and have a problem, my SIM card can not be activated, it tries to verify and then brings an error message that they can not be activated, but the card is fine and other maps I have already tried the same error message. Does anyone know that and has a solution?
Greetings Robert

I had the same with a business sim card of Vodafone. When I tried with the sim of my wife, no problem. So try an other on.

I am now using in my country T-Mobile, this provider is the only one in my country that is not using band 20 (800 mhz). It's working perfect. Wireless can be put off, still working.
So you have to look in your one country what band is used by the provider like this schema,
