We would like to remind you that our new service ZeroBalance is available for your clients starting 21 March 2016!
If your client has run out of funds, ZeroBalance will allow him to request a callback from any another user by simply making an outbound call.
Even with 0 balance user A can dial user B, who will receive an inbound call and will be able to call back. User A should be in the country with free incoming calls, otherwise he should have some balance for at least 1 minute of incoming call.
Please also note that ZeroBalance is not available with extra numbers and in countries with extra rates.
There is no need to install or dial anything additionally. It is absolutely free of charge for you and your clients on TravelSim Classic and TravelSim New cards!
