Does CoolApp allow multiple accounts on one phone?
No. CoolApp can only be registered to one phone number per mobile device. With a dual SIM phone, you must choose one number to register with CoolApp.

How does CoolApp messaging work with dual SIM phones?
Just as if there was a single SIM, CoolApp communication is available with the CoolApp registered number.

  • All CoolApp-to-CoolApp communication is private and end-to-end encrypted.
  • CoolApp can use whichever internet connection is enabled on your phone, WiFi or mobile data from either SIM.

Here’s how to manage dual SIM:
