I have 2 Japanese apps which required authentication codes. 1 of which was previously installed a couple of years ago and at the time, I received the code as expected within a few seconds.
One of the apps has a ticketing feature. I cannot access the ticket screen or receive my ticket without the authentication code. I checked all of my settings for app and phone. All seemed in order. I contacted the app support staff. I contacted EE technical support twice. Staff stated that everything is in order on my end, nothing is blocked and I should be able to receive SMS codes without any problems. I receive SMS messages from the UK with no trouble. She said it is not possible for them to block anything coming in unless it is in my blocked number list. It is not. Friends in Finland, Greece and the USA using the same app have not experienced problems receiving the code or tickets. Based on that, I deleted and re-installed the Japanese app that had previously been authenticated with no trouble to see if the code would come through for that one. It did not.
The issue has not been resolved. I turned spam protection off, cleared all blocked numbers, cleared app cache and data, deleted SMS messages that were sitting on my phone, re-installed the messenger app, re-installed the Japanese app, removed photos from my phone etc. I removed my SIM card and put it back in. I have followed all advice but to no avail. No matter what I do, the authentication codes from Japanese apps do not arrive. After failing to get an authentication code for the app with the ticketing feature, I searched online and can see that a number of other EE customers are experiencing the same problem since the major security update. Getting an eSIM will not solve my particular problem because in order to download my ticket, it can only be sent to the mobile number on the ticket application without exception.
Has anyone else experienced this issue, followed advice, spoke with tech support and still not resolved the problem? At this point, I am convinced that the network security may be causing the problem and it cannot be resolved unless I switch to another network. Can anyone help? I am desperate to resolve this. Thanks.
