Not receiving OTP passcodes

[AngieFoskett]

I’m currently in Cyprus. I have a UK number, enough data and haven’t used my phone excessively. Since yesterday I’ve struggled to receive OTP passcodes. It took a few attempts yesterday but they did come through. Today, nothing. I’m struggling to do mine and Mum’s online banking without access to the passcodes. I’ve also had issues with sending text messages as it says they haven’t been delivered when they have. Mum in turn gets the same message when she replies. I’ve tried everything. I’ve updated to the latest iOS, reset network settings, turned off and on again. I don’t know what to do any more

These are some tips to try :

•   Reboot phone.
•   Manually search for a different network
•   If using an iPhone, change data apn to  mobile.o2.co.uk
•   Call customer service to check for any roaming bars
•   Or if you message O2 using the social media links below, they should be able to help you with this

Remember, OTP's are sms not iMessage.

You might need to increase your spend cap too @AngieFoskett as we sometimes see that a £0 cap interferes with receiving OTP messages.

I had the same problem after moving from Vodafone to O2 and getting a new iPhone15. Not sure if this would work for all but I turned off wifi on my phone, then initiated an OTP from one of the sites that requires them. That worked. I then turned wifi back on and initiated several other OTP requests, all of which also worked. Since then it has been working fine. Note all of that was whilst based in the UK

Thanks for the suggestion. You have actually posted onto the end of a thread that was last active a year ago, but I am tagging @AngieFoskett in case she is still active in this community.
