As for an alternative solution, have you considered using a free UK virtual mobile number for SMS receiving?
Some websites and services provide free virtual mobile numbers that you can use to receive SMS messages. Some examples include receivesmsonline.net and receive-sms-online.com.
If you’re having trouble getting the Sim plugin to work on iOS, using a virtual mobile number for SMS receiving may be a good workaround. This could help you get the information you need without relying on the plugin.
