What others say about the KingKing voice roaming service app

Probably the most critical / useful / unique app from CSL. It becomes one of the factors when considering subscribing to a service provider. Sometimes keeping the local mobile number while staying abroad is crucial to continue daily business. This app helps reduce roaming cost a lot.
When I call HK from Netherlands and Spain during a recent trip the clarity was amazing! The app is free; calls are free (as long as you have wifi), what else can you ask for? :) And people are complaining about the UI for goodness sake!
Just tried HK to HK, it works great no delay, just like a normal phone call. Can't wait to try this overseas. So this is a substitution of roam save? Finally something good comes free. Keep the freebies coming! SGS2
It's free and no lag during conversation. Conversation is clear and stable. No problem using at all. Just need to have stable wifi and don't add country prefix or they will charge u IDD call charges.
