Group Texting contact limit

[s3nonothing]

SIII Galaxy,

Hi,

Can anyone tell me how to increase the group texting contact limit from 20 contacts to 50 contacts.

For the life of me I cannot find a setting for this.

Thanks

I tried to figure it out and I don't even know how to do group testing. Can you please help me out with group testing.
