What if my provider blocks VoIP?
Mobile operators and internet providers in some countries block their clients' access to VoIP via SIP.
In this case, it is still possible to connect to our service via alternative ports.
- Protocol: TCP
- Port: 5065
For example, you need to do the following in Zadarma app for Android and for iOS:
- Choose an account (Settings - Accounts)
- Select «TCP» in transport field (in iOS app choose port 5065)
- click Save
