Not receiving security texts following port

[bearfluff100]

Hi everyone. I ported my number from Vodafone today - all seems ok but I am now unable to receive any security verification texts which means a lot of the apps aren’t working (WhatsApp, online banking etc). From a quick google it looks as though this is a common error. Online chat haven’t been very helpful. Has anyone got any advice? 
Thank you!!

Hi @hertspaul,

Is this only affecting automated texts? We've seen a potential solution on a related thread Not Receiving Santander OTPs 

Please check your messaging app for spam/blocked messages. On Android you open the Messages app, then click on the menu in the top right, and you'll usually have a "Spam and Blocked" option.

For iPhones there should be a couple of relevant settings in Settings > Messages. "Message Filtering" and "Blocked Contacts" should appear in this menu.

If these option don't seem relevant, then you'll be best to advise customer services that you're experiencing a split port. This usually affects calls and texts, but if you let the team know that specifically since porting you aren't receiving messages, they can query this with our porting teams.
