I ported my number to iD Mobile last week and have had an ongoing issue since the transfer completed.
Calls work normally, mobile data works normally and standard person-to-person text messages are also working without issue. However, OTP / authentication text messages from several important services are not arriving, including Barclays, eBay and my work authentication portal (InTime). Some automated texts from certain providers do come through, which suggests SMS is only partially affected.
I raised this with iD Mobile on Friday, followed up again on Sunday and then again yesterday. The issue was escalated to Three for investigation.
I have since been informed by support that Three’s network team advised that the line has been provisioned correctly and everything is showing as active on their side, and the case was effectively treated as resolved from a provisioning perspective.
However, the issue is still ongoing in practice. OTP messages from several services continue not to arrive, despite repeated testing. Given that calls, data and normal SMS all work, but authentication texts fail inconsistently, it still feels like there may be a backend routing / shortcode / propagation issue somewhere that has not actually been resolved.
Has anyone experienced this after porting a number to iD Mobile / Three, where support says provisioning is complete but OTP texts are still not arriving? If so, what finally fixed it?
