Even the connection says good but the other side cannot hear from me and keep telling me that the connection is bad, tried a few calls... I am sure my phone is working fine as it doesn't happen on mobile network calls, conclusion --- this is a crappy useless app!
please add support for dual-SIM phones when have csl sim card and another sim card in the phone, KingKing prompt me to enter my mobile number. but it will never work, unless I turn off the other SIM card.
Not work on dual SIM models Such as lg v10 and g5, please fix. More and more phones have dual SIM slots
USELESS if your device is dual sim model unless you just have 1 sim or switch off sim2.
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.
poor quality, always could not connect!
