Ours is a mobile banking application which contains UPI facility provided by NPCI. For registering in UPI service customer need to complete SIM binding. But our customers who are using iPhone 14 and above with iOS version 17.2.1 and above are unable to complete their SIM binding process during registration process and thereby registration is failing which is causing dismay among our customers. In addition the customers are having enough SMS pack. We have cross checked with the service providers as well but they are also not getting any hits at their end. Kindly help us to resolve the issue so that the users can register without any hassle.
