I switched to O2 from Vodafone and now can’t receive calls from Vodafone sims

[Tirumalatha]

For several months now, my phone hasn't been able to take Vodafone calls. It started with one of my contacts and now there are at least 4 people on my contacts list who are not barred but get the message "this person's phone is switched off" if they try calling.  They can WA me.  I reported this to customer support, the people tried but could not remedy it - SIM swap, tried the SIM in a different phone, etc.  I called customer services and after lengthy conversations and a whole lot of actions  which did not work, including disconnecting my account, they were unable to do anything and referred me to tech. Weeks later I have heard nothing from tech, have raised a complaint (and received no response) and am no further forward. Short of closing my account, what should I do?  Has anyone else had this problem.? (Also been to Vodafone who say it's not their problem either). It is so annoying and frustrating that no-one will take responsibility/fix this issue.

Did you port your number in to o2 when you joined @Tirumalatha ?

It sounds similar to a split port, in that not all the messages in the background are working correctly and unfortunately it is down to o2 to resolve...

@gmarkj Yes I ported my number to O2. tried reaching out to customer support multiple time but still issue not resolved.

Unfortunately we can't really do much more here @Tirumalatha except say keep trying.

Have you been through social media as well as calling?

• Twitter - @O2
• Twitter – DM
• Facebook – @o2uk
• Messenger – @o2uk
• Instagram – o2uk

Whether in the case of split ports or (as here) incomplete, legacy or rogue porting data on a donor network, it is always the responsibility of the current host MNO to resolve - including chasing down the source of the issue, often external.

Apps such as WA, Messenger and suchlike don't use network routing - both your phone & the network operator, handle all usage as pure data traffic. So all this proves is that your phone has a working internet connection.
