Not receiving security texts after porting

[Sls1972]

I ported from Vodafone to Three today, mostly working however, security texts eg NHS app Universal credit, banks are not coming through.  Had no issue when I was Vodafone.  

SMS are also slow to send out.  

Presuming something hasn't quite worked in the porting? Lady i spoke to from Three first was not helpful.  2nd lady was but I'm lacking faith... 

Any suggestions?  

Thank you

I have also tried the old phone and doesn't work either.  I've reset the network etc rebooted airplane mode... it has to be a porting issue

Update I've tried all the steps on other posts and it's not working at all. In google messages the RCS chats is stuck on trying to verify my number.  I've rebooted etc.  Seems to me this is a porting issue... all three said is the wait 72 hours thing. 

Does anyone know what to do?

Porting can take up to 24 hours.

If you are able to receive  calls from other operators it's likely that is NOT a portability problem.

If you have received confirmation that your number been transferred/ported, I would try to enable airplane mode, wait a minute or so and then disable the airplane mode, and try again.

The others users had problems since Tuesday or Wednesday of last week, so your problem is newer.

If no luck contact support on 333 (in case you are on a contract) or chat with them from the app.

Out of curiosity who was original provider when you got your number for the first time(I assume years ago)?

Vodafone I believe.  I've had the number years.  When I ported to Vodafone 2 years ago from three I move a lot.. I had similar issues.  But it's simply now OTP now getting through

ok. for you information, if you failing to make calls/sms and/or data these would not be a problem related with portability. Portability issues manifest mainly on receiving calls and standard sms (not RCS which is over data). If RCS settings verification (of your number) are "stcuk" makes me think that you number was not ported yet to/by Three .

By the way, maybe from your three sim, ring your fixed phone or other person's mobile phone and check whether your ported number is shown.

the other guys are now going on around sometimes being able to receive OTPs depending on wether they are (different areas), but imo it doesn't make sense to me being the problem being related with coverage or cells or mobility or spectrum or "radio frequencies" (whatever name).

My number shows but still not verifying.  I can no longer receive texts either whatsoever.  

Makes me wonder if they're doing something to my phone number?
