It is recommended to use Call Out when you have a flat rate in your mobile phone that also includes call set-up charges. Please verify there is a local Infocaller number in your area. Thus, you’ll be able to make calls using Infocaller App’s competitive rates.
Call Back is recommended when you do not have a flat rate on your mobile phone or when you are traveling abroad with a SIM card that does not include minutes of use. Making calls through Call Back with Infocaller App are cheaper than using your carrier’s tariffs to the main destinations. In addition, Call Back has no call setup charges and does not use minutes inbound from your phone company.
VoIP call is recommended if your rate does not have available minutes or if you only have access to data, we connect you by Internet without using minutes of the rate that you have with your operator.
