Caller gets several rings even when I have no signal

[Anonymous]

I always used to get O2's missed call (technically the abandoned call type of alert) texts to say someone had called but couldn't get through, now I don't get these - unless I've been trying to ring someone at the same time they've been ringing me or when Do Not Disturb mode is on.
Sometimes someone will ring me and I will have no service but it will still ring a few times and then divert to voicemail but I don't get any notification of it. Very frustrating!
I have Tugo and wondered if this could be responsible for it ringing when I don't actually have any signal or connected to wifi. I have also changed phones and SIM card since this problem first began and no difference. My call forwarding is off so it's not that.
Any help/similar experience would be greatly appreciated!

with tugo this will happen due to its voicemail service.

Is there anything you can do to reverse this? Even when I delete Tugo it still happens.

Are you after removing tugo then turning voice mail off ?

follow @MI5's guide http://community.o2.co.uk/t5/Other-Products-Services/All-you-need-to-know-about-O2-Voicemail-901/td-...

You need to turn off VM in tugo then logout of app.

It doesn't let me turn it off in the app, just keeps saying error?

Solved!!
I had to actually delete my Tugo account and then uninstall the app. I then turned off my voicemail (1760) and turned it on again (1750) and then reactivated my missed call alerts and it works!
Also it goes straight to voicemail when I have no signal now - FINALLY!!

When deleting the app you always need to tick the  box to remove all data. Your o2 voicemail or text alert on 1710 will then work as it should.
