Is it worth to sign up for GAC if you can only attack in one match?

Next week it looks like I will be somewhere with no cellphone or wifi during the attack phases of the 2nd and 3rd matches. I think it is still worth signing up for the whole week anyway even if I will probably lose the first match, but can make at least one attack for that round. I'll lose ranking, but get some rewards. Is that correct?

Thanks.
