How to activate cellular service with Mangoh Yellow?

[jyijyi]

Here says voice call is not supported in wp77

Voice call sample app available

Hi Asyal, What WP modules can handle Voice calls? I was going back down and find WP7502 working fine on Mangoh red as the only one. Is the limit on module hardware or legato support? Is voice call support planned for Mangoh yellow with WP7702? Thank you Mirek
