Yeah the unfortunate situation of Android devices means that you may have only just bought the phone but if it isn't supported you could be running a very old OS version. In this case I think Android 5 was 2014, so almost 7 years old a this point. Amaysim are pretty good, Though if you can convince them to add a security note to your account its worth it (Colleague of mine had his mobile number hijacked while on holiday and they used it to access a few of his online accounts)
