Not receiving security texts after porting

Sls1972 — Tue, 13 May 2025 21:44:14 GMT

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

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

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

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).

Hi @Sls1972,

Sorry to hear about the issues with your port. We're looking into some similar issues around security/OTP (One Time Passcode) messages for a few customers who have recently ported. The element of your RCS not registering, and slow texts hasn't been mentioned by the others though,

Can you both make and receive calls okay? When you ring someone does it show them the number you ported or the temporary Three number? How about with normal texts from other mobiles, are they being received?

Thanks,
Jonathan

Hi Jonathan.

I can make and recieve calls okay. I'm getting some texts.

OTP are the ones not getting through, plus my number is stuck on verifying on RCS on google messages.

Everything else seems to be working.

I've checked the sim in my old phone same issue. OTP not being received.

Three said it should be working tomorrow... and allow 72 hours but I'm not so sure. It's got to be a three issue as I had no problems on Vodafone whatsoever.

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?

Hi @Sls1972,

It sounds like this could well be a split porting issue based on what you've shared. I'm not certain your case is the same as the others we've been seeing as there's a few differences, or possibly you've been affected by 2 issues simultaneously.

Does your phone settings allow you to switch RCS off, or is it "stuck" on this on but verifying message? I think it may be best to switch it off till the porting issue has been addressed, then try activating again once you're receiving normal SMS consistently.

Did the team advise they'd raised an investigation with our porting team, and that they'd be back in touch within the 72 hours?

Thanks,
Jonathan

Hi @Sls1972,

The more widespead issues with receiving OTPs and verification texts appear to be resolved. Are you now receiving these? As I mentioned before, I'm not sure this explains everything you've been experiencing, but please let me know how you're getting on and if you're seeing any improvements?

Thanks,
Jonathan

Hi Jonathan,

I didnt want to start a new conversation as i think my issue is the same but please let me know if i should.

I just ported to Three and i have been having the same issue. I cannot receive NHS A2P messages to my device. I checked to see if it is a NHS issue by registering a different number and it worked. I changed it back to my number and no messages are arriving which means i cannot log into my NHS App.

Contact 3 and tell them you are not receiving the OTP (one time passcodes). Mine was a porting issue, they didnt port correctly. Get them to check it for you.

I meant to add, you will get the three texts but theirs always seem to come through. I did get theirs but no one else's.

Hi @g1105t,

This topic relates to a past issue which was resolved, but if you're still having issues, and the messages definitely aren't popping into a spam/junk inbox, then please contact customer services and they can raise an investigation with our porting team.

Thanks,
Jonathan
