I finally had enough after my previous posts and got my PAC for my 3 sims. I can't have messages and other issues such as calls going through to voicemail especially when contacting my 13 year old daughter. Just got 3 sims for EE now and paying £36 per month in total with 100b data I can gift to 3 sims. At least I know this issue will not happen and signal is much better with the added bonus of VoLTE.
I left Virgin Mobile about 10 months ago because of the delayed/missing push notification issue/messages combined with missing 2FA codes from Google (who at the time acknowledged a problem with VM which is more than VM did).
I just stopped by to see if this issue had been fixed, it obviously hasn't so I'll stay away.
For those expecting a quick fix, please don't! As I say I left approx 10 months ago and was having the issue for the months I was with Virgin before ending my contract early.
Same issue for a while with whatts app and any other notification tryed all fixes possible. In the end even tryed going back to an older phone i know works, still same problem if this is not going to be fixed my next solution will be to switch networks and never return i can not go on missing messages from my gf and friends because virgin do not want to recognise the problem.
