I used to use DIDlogic with my Nokia phones and, after some torturous\nsupport issues to get the config right, it worked great with the VOIP\nfunctionality built into Symbian.\n\nI never got it working for incoming calls, properly, because Nokias\nnever had the keep-alive processes needed to keep NAT holes etc etc\nopen.\n\nBut I need outgoing calls only, and need to present my UK mobile\nnumber, which DIDlogic did fine.\n\nNow I have a Samsung S6 (android) and using Csipsimple which is one of\nthe most popular VOIP apps.\n\nBut I am unable to make it work. It *may* be logging in, but DID\nchanged their web control panel to no longer show whether you are\nlogged in so I cannot tell, and I cannot make any calls. But I get no\nmore login error messages.\n\nAnd DID have blacklisted me from continued tech support... they seem\nto have a quota on emails and then cut you off.\n\nCan anyone recommend another good PAYG service which actually works?\n\nI have tried VOIPdiscount but they would not connect to people I tried\nto call in Germany and France. Eventually I got some of my money back.\nThey later claimed they fixed it...\n\nI don't want a VOIP firm which forces you install their own app. Those\nare nearly always horrible.\n\nMany thanks for any tips.
